Fix design of the pad filter. Previously the pad filter just drawed borders in the surrounding of the input without checking if this area was allocated or writeable. Now we check and allocate a new buffer if the input is unsuitable.
Add w,h,format back into AVFilterBuffer, these are required for direct rendering. These fields are needed to be able to know which area of memory is allocated and which is off limits. This reverts 24291 and parts of r24424.

Change the default dB-per-bit code from 2 to 3. This gives slightly better quality in PEAQ tests. Code 3 gives a dBpb value of 2816 = -132dB (128 psd units = -6dB), which corresponds to 22 bits. Since the exponents have an offset applied, the 16-bit source looks like 24-bit source to the bit allocation routine. So using dBpb code=3 is a closer match to the exponent range.

Check user-specified cutoff frequency in validate_options().
10l: fix encoding for LFE channel
Increase buffer size because the header itself can be larger than 8192 (largest size according to spec: 64k). Fixes playback of mmsh://a1635.v24937.c2493.g.vm.akamaistream.net/7/1635/2493/v0001/premrad.download.akamai.com/2493/premiere_rock_report/Country_Report.wma

Simplify bit allocation search by using a loop for the SNR offset increment.
Improve layout and clarify / complete documentation for the yadif filter.
Do not calculate psd and masking curve if exponents are being reused. Approx. 20% faster in function bit_alloc_masking().
cosmetics: reindent after last commit
Copy bap from previous block when exponent strategy is EXP_REUSE. We can do this because exponents are the only bit allocation parameters which change from block-to-block currently. Approx. 57% faster in function bit_alloc(). Approx. 25% faster overall encoding.
Count grouped mantissas for each block all at once at the end of bit allocation for each block. 24% faster in function bit_alloc(). Approx. 10% faster overall encoding.
Count bits for fixed parameters at start of encoding rather than in every frame.
Use a LUT for number of exponent groups.  This avoids recalculating it for every block and channel for every frame.
Speed up group minimum and group output calculations for EXP_D25 and EXP_D45 in encode_exponents_blk_ch() by removing the inner loops. This is about 30-40% faster for the modified sections.
Convert a for() loop into a while() loop for the downward part of the exponent delta limiting.
Redesign encode_exponents_blk_ch() so that duplicate exponent sets are no longer required. This gets rid of the temp buffer as well as encoded_exp in AC3EncodeContext. It also allows for skipping the exponent grouping for EXP_D15. 56% faster in encode_exponents_blk_ch().
Use optimized function DSPContext.sad[0]() instead of calc_exp_diff(). 90% faster compute_exp_strategy().
configure: Avoid warnings if av_always_inline is disabled

Write results of post-rotation complex multiply directly to output. 2% faster in function mdct512().
Use memcpy() instead of a for loop in mdct512(). 8% faster in function.
Allocate all large per-channel arrays using av_malloc(). Decreases memory usage for less than 6 channels.
Make windowed_samples 16-byte aligned. This will allow future SIMD optimization of the window function.
Allocate planar_samples using av_mallocz(). Lowers memory usage when encoding less than 6 channels.
Allocate bap and bap1 buffers using av_malloc(). This reduces the memory footprint when using less than 6 channels. Modify bit allocation to swap the 2 buffers instead of using memcpy() and use per-block pointers for bap. This is slightly faster (0.3%) in function cbr_bit_allocation().
rtsp: Don't set the RTP time base from the sample rate if no sample rate is set
Remove last_samples[] and copy directly from planar_samples[]. Avoids memcpy that was used to store last samples for next frame. Approx. 3% faster in function deinterleave_input_samples() and reduces memory usage by 3kB.
Remove unneeded line. key_frame is already set to 1 in avcodec_alloc_frame().
cosmetics: comment clean-up and misc cosmetics

Cosmetics: put "if (...)" and "av_log(...)" in the same line for improving vertical alignment and readability.
rawdec: Properly pass reordered_opaque through the decoder

Use sse2 variant of put_pixels16() for no_rnd also. Provides a minor speed increase to e.g. vc1, snow and mpeg decoding.
Allow setting the impulse block bias for libvorbis through a private codec parameter. First example and test of private codec parameters.
Move allocation and init to defaults of the private codec contexts to avcodec_get_context_defaults3(). That way the user app can set codec specific parameters in the private context before opening it.
Merge b_idx and edge variables, and optimize the ASM to directly load variables from memory locations/offsets depending on b_idx plus constants, rather than having gcc do this. This saves several lea calls and together saves about 10 cycles in h264_loop_filter_strength_mmx2().
Remove mv_mask variable. Replace the related pand -1/0 instructions by either a pxor, or remove the instruction alltogether. Altogether, this saves 1 instruction.
Remove d_idx as a variable, and instead load it as a constant in the asm. This has no measurable speed effect because the surrounding code doesn't take advantage of this yet.
Unroll inner bidir loop in h264_loop_filter_strength_mmx2(), which gets rid of the d_idx variable and therefore allows for future optimizations. No speed difference by this commit itself.
Unloop the outer loop in h264_loop_filter_strength_mmx2(), which allows inlining various constants within the loop code. 20 cycles faster on cathedral sample.
Put if (...) av_log() in the same line, more compact and increase readibility.
Amend constraints for the src_format and dst_format options in the SWScale context.
Fix compile on Darwin (FATE). Compile error: yadif.c:226: error: can't find a register in class 'GENERAL_REGS' while reloading 'asm' yadif.c:220: error: 'asm' operand has impossible constraints

Check avctx width/height more thoroughly (e.g. all values 0 except width would have been accepted before). Also do not fail if they are invalid but instead override them to 0. This allows decoding e.g. MPEG video when only the container values are corrupted.

The 24-bit ydt also should not depend on endianness, since all of it ends up in a single 32-bit pixel. This seems likely to be wrong though, since it is different from the 15 and 16 bit modes and might explain the half-width issue for 24 bit truemotion.
Since the 24 bit format is decoded to endian-dependant BGR32 and not BGR24, do not swap red and blue on big-endian for this format as well.
Do not swap red and blue when decoding truemotion on big-endian.

Only check for for libvpx decoder/encoder if libvpx is enabled.
fix configure when --enable-libvpx is not specified
Split libvpx check into decoder and encoder check. This allows using a libvpx that has been configured as decoder/encoder only. patch by Frank Barchard, fbarchard google com
Split h264dsp and h264pred in configure. Many H.264 derivatives, like RV40 and VP8, use the H.264 prediction functions but not the weight/loopfilter functions. This should reduce the size of builds with one of these derivatives but without H.264 decoding itself.

vorbisdec: Return AVERROR(ENOMEM) on malloc() failure.
vorbisdec: Prevent a potential integer overflow.
The VP8 decoder does not depend on cabac.o.
The VP8 decoder does not depend on vp56.o and vp56data.o.
Remove redundant h264pred.o from VP8 objects list. It is already selected through the H264DSP dependency of VP8.
VP8: eliminate a dereference in coefficient decoding
VP8: much faster DC transform handling A lot of the time the DC block is empty: don't do the WHT in this case. A lot of the rest of the time, there's only one coefficient: make a special DC-only transform for that case. When the block is empty, don't incorrectly mark luma DCT blocks as having DC coefficients.
vorbisdec: change a uint_fast32_t to 'unsigned', fix llvm-gcc build
VP8: move zeroing of luma DC block into the WHT Lets us do the zeroing in asm instead of C. Also makes it consistent with the way the regular iDCT code does it.
lavfi-regression: trim \r line ends from showfiltfmts output
Add -Wno-parentheses to CFLAGS. Without this flag -Wall generates warnings that nobody wants to see fixed or worked around. Disabling those warnings is thus the best solution.

lavfi-showfiltfmts: print one format per line
Remove temporary files in lavfi-pixfmts test
Fix fate-lavfi-pixfmts test cross-compilation.
Use the ffmpeg specified in $ffmpeg in the pixfmts lavfi test, otherwise the test will be running whatever ffmpeg is installed on the host system.
Put the filter name before the pixel format name in the lavfi pixfmts test output files, and add a prefix with the name of the test. Make per-filter grouping of the generated output files easier, which is more useful than per-pixel-format grouping.
Introduce and use a variable $output in the lavfi pixfmts test code. Consistent with the lavfi pixdesc test code, and slightly improve readability.
Split the lavfi pixfmts tests in _le and _be, this is required as the test results and references depend on machine endianess.
Rename the not yet enabled test lavfi_pix_fmts to pixfmts, which is simpler and consistent with the names of the other lavfi tests.
Add WebM to the Matroska demuxer name.
Use word-writing instead of dword-writing (with two cached but otherwise unchanged bytes) in the horizontal simple loopfilter. This makes the filter quite a bit faster in itself (~30 cycles less on Core1), probably mostly because we don't need a complex 4x4 transpose, but only a simple byte interleave. Also allows using pextrw on SSE4, which speeds up even more (e.g. 25% faster on Core i7).

Resize AVFilterBuffer to hold 8 planes/linesizes worth of data.
Rename the av_fill_image_linesize() formal parameter linesize to linesizes, for consistency with the function declaration.
Reimplement av_fill_image_pointers() using the information stored in the pixdescs.
Make av_fill_image_linesizes() return a meaningful error core rather than -1.
Rename av_fill_image_linesizes() internal variables max_plane_step and max_plane_step_comp by removing the "plane_" word, and add a comment for explaining what they represent.
Make avpicture_fill() directly call av_fill_image_linesizes() and av_fill_image_pointers() rather than their wrappers ff_fill_linesize() and ff_fill_pointer().
Make avfilter_default_get_video_buffer() use functions in libavcore/imgutils.c rather than ff_fill_linesize() and ff_fill_pointer().

Reindent after r24516.
Use inverse error branches, i.e. instead of if(something){success} else {error}, use if(!something) {return error;} success;, which needs less indenting.
Use av_log(.., AV_LOG_ERROR) instead of dprintf() for logging errors. This should help in making mmst a little more userfriendly, or at least debuggable. Also use helpful error return values instead of -1.
Use pmaddubsw for the mbedge_filter (>=ssse3), 6-10 cycles faster.
VP8: Much faster SSE2 MC 5-10% faster or more on Phenom, Athlon 64, and some others. Helps some on pre-SSSE3 Intel chips as well, but not as much.
Define static functions fill_image_linesize() and fill_image_data_ptr(). ff_fill_linesize() and ff_fill_pointer() now wrap these functions.
Enable no-loop memory/register saving for ssse3/sse4 also.
Save a register (or regsize of stackspace for x86-32) for the no-loop mbedge loopfilter functions, by re-using space that holds a variable that we no longer need.
Use nested ifs instead of &&, which appears to not work with %ifidn (i.e. this construct was always enabled, even for <ssse3 versions).
Rename pow variable to pwr.
Split pextrw macro-spaghetti into several opt-specific macros, this will make future new optimizations (imagine a sse5) much easier. Also fix a bug where we used the direction (%2) rather than optimization (%1) to enable this, which means it wasn't ever actually used...

Only 4-bit ADPCM IMA WAV files are supported.
Cosmetics: rename enc -> dec in opt_input_file().
Move ffm_close function up to avoid a forward declaration.
ffmdec: Do not manually free streams on read_header error, this is always handled by upper layers. Fixes double-frees (issue 2003). Instead call ffm_close to ensure rc_eqs are freed also in the error case.
Fix obvious bug in assignment. Somehow, the test vectors don't test this...
add SubRip muxer and demuxer
Fix SPLATB_REG mess. Used to be a if/elseif/elseif/elseif spaghetti, so this splits it into small optimization-specific macros which are selected for each DSP function. The advantage of this approach is that the sse4 functions now use the ssse3 codepath also without needing an explicit sse4 codepath.
Simplify lavfi test script a little
Unbreak parallel lavfi testing

VP8: use AV_RL24 instead of defining a new RL24.
swscale-test: scale from reference to source only once for each algorithm
indent
swscale-test: change order tests are run, maintaining the same algorithm for sequential geometries instead of running all algorithms sequentially for each geometry.

Add VP8 sign bias code regtest. Not tested by the official conformance suite.
VP8: fix broken sign bias code in MV pred Apparently the official conformance test vectors don't test this feature, even though libvpx uses it.
VP8: optimize DC-only chroma case in the same way as luma. Add MMX idct_dc_add4uv function for this case. ~40% faster chroma idct.
VP8: Clean up some variable shadowing.
VP8 asm: cosmetics (spacing)
VP8: 30% faster idct_mb Take shortcuts based on statistically common situations. Add 4-at-a-time idct_dc function (mmx and sse2) since rows of 4 DC-only DCT blocks are common. TODO: tie this more directly into the MB mode, since the DC-level transform is only used for non-splitmv blocks?
VP8: smarter prefetching Don't prefetch reference frames that were used less than 1/32th of the time so far in the frame. This helps speed up to ~2% on videos that, in many frames, make near-zero (but not entirely zero) use of golden and/or alt-refs. This is a very common property of videos encoded by libvpx.
In h264 parser, return immediately if buf_size is 0, avoid printing erroneous message for last frame.
In mpegts muxer, fix rbsp trailing bits in AUD nal, fixes issue #2122

VP8: avoid a memset for non-i4x4 blocks with no coefficients
Get rid of more unnecessary dereferences in VP8 deblocking
Shut up an uninitialized variable GCC warning in VP8.
Smarter VP8 prefetching Prefetch all refs (including altref), but only if they've been used so far this frame. ~2.5% faster overall.

Increase flexibility of PRINT_LIB_VERSION(), make it accept a flags parameter. Allow a pending factorization.
Map settings for 2-pass libvpx encoding.
Eliminate a pointless memset for intra blocks in P-frames in VP8
VP8: Don't store segment in macroblock struct anymore. Not necessary with the previous patch.
Convert VP8 macroblock structures to a ring buffer. Uses a slightly nonintuitive ring buffer size of (width+height*2) to simplify addressing logic. Also split out the segmentation map to a separate structure, necessary to implement the ring buffer.
Add APIchanges entry for the libavfilter media format generalization change of r24424.
Generalize pixel format enum fields to int formats.
Document create_filter().
Add simple doxy to link_filter().
Fix documentation for parse_link_name().
Consistently use Uppercase for the first character of the log messages.
Make link_filter() propagate the generated error code.
Fix style: "if(" -> "if (".
Calculate deblock strength per-MB instead of per-row Gives better cache locality, since the VP8Macroblock structs are still in cache. Inspired by the way x264 does it.
Avoid tracking i4x4 modes in P-frames in VP8 As in the previous commit, they aren't used for context selection, so it saves memory this way.
Avoid useless fill_rectangle in P-frames in VP8 In VP8, i4x4 only uses contexts based on neighbors in I-frames.
Optimize partition mv decoding in VP8
Take shortcuts for mv0 case in VP8 MC Avoid edge emulation -- it isn't needed if there isn't any subpel.
Much faster VP8 mv and mode prediction
Convert vp56_mv to 16-bit. Saves nothing except a bit of memory/cache now, but will allow future optimizations.
Add prefetching to VP8 decoder ~5% faster overall, probably depends on CPU and resolution.
Fix and enable horizontal >=SSE2 mbedge loopfilter.
relicense h264 deblock sse2 to lgpl
Add APIchanges entry after libavcore addition.
sync yasm macros from x264

Allow the ASF header to be transferred split over multiple packets, as some servers happen to do. For this, we also move several header-size-related variables to the MMSTContext.
Explicitely set the size of the "ff_asf_head1_guid" header chunk, this is part of the spec and causes problems otherwise.

Revert r24339 (it causes fate failures on x86-64) - I'll figure out what's wrong with it tomorrow or so, then re-submit.
Remove FF_MM_SSE2/3 flags for CPUs where this is generally not faster than regular MMX code. Examples of this are the Core1 CPU. Instead, set a new flag, FF_MM_SSE2/3SLOW, which can be checked for particular SSE2/3 functions that have been checked specifically on such CPUs and are actually faster than their MMX counterparts.
Implement chroma (width=8) inner loopfilter MMX/MMX2/SSE2 functions.
Be more efficient with registers or stack memory. Saves 8/16 bytes stack for x86-32, or 2 MM registers on x86-64.
Change function prototypes for width=8 inner and mbedge loopfilter functions so that it does both U and V planes at the same time. This will have speed advantages when using SSE2 (or higher) optimizations, since we can do both the U and V rows together in a single xmm register.

In addition extradata is required for many codecs and thus in contrast to sub_id generally already passed on by any programs using libav*. Also ask for a sample if we encounter a stream with multiple/changing IDs.

Simplify MV parsing, removes laying out 2 or 4 (16x8/8x8/8x16) MVs over all 16 subblocks (since we no longer need that), which should also lead to a minor speedup.
Optimize split MC, so we don't always do 4x4 blocks of 4x4pixels each, but we apply them as 16x8/8x16/8x8 subblocks where possible. Since this allows us to use width=8/16 instead of width=4 MC functions, we can now take more advantage of SSE2/SSSE3 optimizations, leading to a total speedup for splitMV filter of about 10%.

Allocate enough memory for audio_buf to fit a full output frame. Also, use audio_buf when encoding the final frame. Fixes Issue 1921.
Quant changes only once per MB so move the corresponding scale factor assignment out of the block decoding loop. Indeo4 doesn't use any scale table but the quant level itself as scale. Therefore access scale table only if its pointer != NULL.

Open 2-pass logfile in binary mode for both reading and writing. This fixes a regression on Windows introduced by r22769 in which the data read from the file was not properly zero terminated. The file was read as text, which caused the \r characters to be suppressed. Since the zero termination happens at the end of the buffer, and there was one byte less read per line, this caused the remaining space on the buffer to contain random data.

Make the IFF demuxer a little more standards-compliant, e.g. respect the size fields of common media header chunks (these can have different sizes depending on the type of IFF file you read), better handle odd sizes (like RIFF, every field is padded to word) and handle headerchunks after the BODY chunk.
Reidnent after r22795.
Move some branches outside looped code. Should improve the generated asm (and thus performance) slightly.
Switch some ints to unsigned (they can only have positive values, this allows compiler to optimize some math from mul/div to shr/shl). Also add a cast to uint32_t when calling decodeplane32(), this silences a compiler warning. Lastly, in decodeplane8/32(), flatten a double-loop into a single-loop and calculate the length once before entering the loop instead of during every iteration (since it doesn't change).
Make ffmpeg use print_error() to make apparent the exact cause of failure happened when trying to open the output file.

Document API addition of avcodec_copy_context().
Fix FFM-based streaming from ffmpeg to ffserver. The basic problem is that we'd memset() the codec context to zero, thereby setting audio input to U8 and video to YUV420P. For most video encoders, that actually works, but for most audio codecs, it doesn't. This patch changes defaults to those set by avcodec_context_get_defaults() and have ffmpeg figure out the optimal encoding format itself if not set explicitely (as it does for the non-ffserver-cases also).
Add avcodec_copy_context().
Add entry for the addition of av_match_ext() to the public API.

DWT: x86 init should depend on HAVE_MMX
error.h: test EDOM instead of EINVAL
Add missing includes to libavutil/error.h
Change the definition of AVERROR_NUMEXPECTED at the next libavutil major bump, using an FFmpeg specific error code rather than EDOM, which has a quite different semantics.

Avoid creating tiny (possibly only 64 bytes large) audio packets resulting in huge processing and memory usage overhead for avi files with raw PCM audio.
Make sure all mvs of a mb are set in the error concealment code.
Mark AVERROR_ENOENT for deletion at the next libavutil major bump.
Lexically sort the error code definitions.
Ensure that the deblock filter accesses the correct MVs for h264.
aacsbr: DSPUtilize analysis input scaling.
aac: Don't bias output during the IMDCT if SBR will be used.
Mark AVERROR_ENOMEM to be deleted at the next major bump.
Replace all the occurrences of AVERROR_EIO with AVERROR(EIO), and mark AVERROR_EIO for deletion at the next major bump.
Make iff.c:decode_init return the value returned by avctx->get_buffer() in case of error, rather than AVERROR_UNKNOWN which is deprecated, and mark AVERROR_UNKNOWN for deletion at the next major bump.
CODEC_ID_XVID is not used anywhere, remove it at next major bump
bump minor avcodec version for libxvid codec id change (r22489)
Make the scale filter pass the pkt.pos information to the output picref.
Bump libavfilter minor version and add APIchanges entry after the addition of the AVFilterPicRef.pos field.
Make ffplay pass the packet.pos information to the filterchain, get it again from the filterchain and pass it back to output_picture2().
Add AVFilterPicRef.pos field and make libavfilter propagate stream byte position information, as stored in the pkt.pos, through the filterchain.
Extend the slice filter to make it issue slice height values randomly choosen between 8 and 32 when the supplied parameter is the string "random".
vp3: Split out motion vectors to their own array

Fix guess_mv() so that it works correctly with 4x4 MV blocks.
Fix indention
Always reset slice_table. Previously, the area of a lost slice would be left at the slice number of the previous frame which could occasionally match the number of the next slice and thus a non existing slice could have been used for prediction leading to additional decoding errors in otherwise undamaged slices.

Add myself as maintainer of the bink demuxer and bink audio decoder
Simplify code to set cbp_* this seems 1 cpu cycle slower even though we practically just remove code. Speed loss seems caused by the merge of if(left_type), iam commiting this anyway as i cant imagine this to be anything but compiler messup.
Fix typos in ref_index documentation.
Move init of right side of ref_cache from fill_caches() to init_the_darn_decoder().
Remove 3 mv_cache zeroing instructions that zeroed the right side. This seems unneeded as nothing seems to ever set it to non zero values.
Remove useless check of the 2 left MBs of a pair being in the same slice.
Clarify ref_index.
Remove unneeded line of code from the neighbor setting code in h264.
Simplify code in mv_pred. Not benchmarked as this is petty much just code removial.
Get rid of mb2b8_xy and b8_stride, change arrays organized based on b8_stride to ones based on mb_stride in h264. about 20 cpu cycles faster overall per MB
Disable suffix rules
Remove pointless empty line.
Apply consistency nit.
Add the graph2dot tools and document it.
Replace not anymore valid syntax "-title X" with "-metadata title=X".
svq3 now in working condition, at least vissually, ill let fate tell us if the checksums match

Dont allocate direct_table 8 times too  large.
Store data in direct_table interleaved. seems 20cpu cycles faster
Simplify intra4x4_pred_mode_cache init.
Reorder intra4x4_pred_mode so that we can read/write 4 values at once. 3-7 cpu cycles faster
Store intra4x4_pred_mode per row only. about 5 cpu cycles slower in the local code but should be overall faster due to reduced cache use. (my sample though has too few intra4x4 blocks for this to be meassureable easily either way)
unroll tiny and trivial loop. Same speed but clearer.
asf: indent. Patch from Anton Khirnov wyskas gmail com
asf: add more entries to metadata conv table. Patch from Anton Khirnov wyskas gmail com
Cut the size of mvd_table by yet another factor of 2. The code read/write code itself was 1 cycle faster, overall its likely more due to cache effects
Keep mvd_table values of only 2 mb rows.
10l: add prefix "TAG:" to the metadata tags key showed for each stream.
Cosmetics: replace "filename" to "arg" for the name of the argument of opt_input_file(). More consistent and more clear, as "filename" can be easily confused with the global "input_filename".
aac: Keep decode_band_types() from eating all padding at the end of a buffer.
Extend doxy for the src parameter of av_fifo_generic_write().
3rd and hopefully last 100l fix.
Fix doxy and assert().
Try to fix 100l compilation failure on some systems.
Change mvd_cache & mvd_table to 8bit, this is overall a bit faster for high resolution videos. about 20cycles faster per MB for cathederal.
AV_COPY16() & AV_ZERO16()
Extend fill_rectangle() support for 16bit
Calculate mvd without abs() same speed (ask gcc why, i dont know)
Read ASF metadata as proper UTF-16 and spit it out as proper UTF-8 in our metadata system.
Don't add WM prefixes to all written ASF tags.
switch back to (amvd>2)+(amvd>32), its 5 cpu cycles faster now.
Eliminate put_str16().
Add PUT_UTF16() macro.
Factorize common code from the top of decode_cabac_mb_mvd() 10-15 cpu cycles faster.
Mention that metadata tags are (unvalidated) UTF-8.
Replace mvd>2 + mvd>32 by MIN((mvd+28)*17>>9, 2) same speed as far as i can meassure but it might have fewer branches on some archs. Idea from x264 / jason
Clear freed pointer in ffplay.c. Fixes a crash when audio stream is cycled twice.
Replace ad-hoc fill rectangle by fill_rectangle().
ff_msmpeg4_decode_init() calls ff_h263_decode_init() which calls MPV_common_init(), so calling both is redundant and leads to memory leaks in WMV3/VC-1 decoder. Thus use only the first function in WMV3/VC-1 decoder initialization.
it is not necessary to display the decoder name, as av_log() automatically prints the context

Split rtsp_read_header() into two functions, so that the main part (now also known as rtsp_connect()) can be used in the RTSP muxer.
Split out input-specific parts of rtsp_read_header() into its own, new, function (rtsp_setup_input_streams()), as preparation for the upcoming RTSP muxer.
Only send out NAT-punching RTP/RTCP packets when we're in demuxer mode, i.e. don't send them when acting as a RTSP muxer.
Use mode=receive instead of mode=play if in RTSP muxer (instead of demuxer) mode.

Move predict_field_decoding_flag() from h264.h to .c as its only used there and belongs there as well.
Move check for and call of predict_field_decoding_flag() from the mb code to the row code. This function would only be needed on a MB basis for MBAFF+FMO
2x faster ff_h264_init_cabac_states(), 4k cpu cycles less. Sadly this is just per slice so the speedup with normal files should be negligible.
Remove first_rtcp_ntp_time. This is used to prevent overflow of the timestamp, but doesn't actually do that. What's worse, it creates timestamp adjustments that are different per stream within a session, leading to a/v sync issues.
When using RTP-over-UDP, send dummy packets during stream setup, similar to what e.g. RealPlayer does. This allows proper port forwarding setup in NAT- based environments.
Rename the "enc" variable, which refers to the AVCodecContext of a decoder, to "avctx".
Move read_line() and write_line() definition from pixdesc.h to pixdesc.c, which are now not anymore marked as static inline.
Fix two problems (no idea how this ever worked): - the return value of url_open_dyn_*buf() is 0 on success, so using    if (!(res = url_open_dyn_*buf())) return res; is not going to work - url_open_dyn_packet_buf actually writes the max_packet_size before    each piece of data. Feeding this to the ASF demuxer will never work.    Therefore, use url_open_dyn_buf() instead.
Revert r21851.
Don't return 0 if buffer setup failed. That signals the RTSP demuxer that the packet was filled in, leading to virtually random behaviour in the decoder later on. Instead, return a negative value.
Set lavf identification string globally in av_write_header(), rather than inside the muxers. Remove special handling of "encoder" tags from AVI and MP3 muxers.

Clean after toggling wave. Fixes issue1180.
Use pixel format descriptors for checking if the input format is paletted. Simpler and more robust.
Try to open decoders in av_find_stream_info() even if no packets for the stream are found. Fixes issue1385
Move is->frame_timer init from start to flush_pkt handling so it is also done on seeking. This fixes the bug where after reaching the end and waiting a few seconds seeking back to the begin messes up AV sync and playback speed.
Make opt_frame_pix_fmt() call show_pix_fmts() if the provided option is "list".
The convertion between bit and byte is 8 not 60. Fixes wrong cursor key seek distances.
Correct opts calulation in ffmpeg.c. This correct the stop point for demuxing with -vcodec copy and -t as well as packet interleaving. (we already diddrop packets but kept demuxing them for too long due to opts being wrong) the change to ffm is due to 2 packets with timestamp 0 being stored in different order.
Alternative solution for the mpegvideo_split + mov problem.

Revert 	r12684 | michael | 2008-04-04 02:43:34 +0200 (Fri, 04 Apr 2008) | 2 lines 	Disable the split function. This should end the mpeg1/2 global header issues. The split function is essential for -ss to work Fixes issue1226 If this breaks something please tell me, also if someoen remembers what problem this originally caused tell me too, i searched but couldnt find it.
Only set duration for streams where it is likely correct. Fixes issue1120
Set nb_frames. Also add DXSA tag (commited by mistake in this commit, i can revert and recommit seperately if someone wants)
Compare the correct clocks for syncing video to audio/ext. Fixes initial delay on video from issue1134.

Check pkt.pts against the recording time. This fixes at least ogg encoding with -t where the file was slightly too long.
Use pixel format descriptors to check if the input format is paletted.
mention symbol versioning
Make sure the faulty timestamp detection is just done when we have a picture from the decoder.
Reset frame_last_delay to 0. This avoids a few ms delay for the first frame after a seek in theory.
Move frame_last_delay into flush code as it must be reset on seeks to, otherwise the first frame after a seek would be delayed by that amount.
Reset frame_last_pts on flush (and thus also at start) fixes issue558 and probably others.
Insert a flush packet into the que on init, that way common code between flush and init can be put into the flush handling.
"Flush" the picture que on seeks, this prevents the display thread from having frames from before and after the seek which just isnt a good idea.
Add a list of generic tags and change demuxers to follow it. Patch by Anton Khirnov, wyskas at gmail dot com

Fix seeking by bytes with the mouse and do so by default if the duration is nonsense.
Flag to ignore dts on frames that contain pts. This works around common issues with mpeg-ps files with broken timestamps. Also allows playing the broken sample from issue1024.
Fix AVFormat AVOprions.
Store strings directly in mov_mdhd_language_map instead of using pointers, which has a up to 200% overhead. Also allows to use memcpy instead of strcpy.

Split first reference list comparission from mv comparission. about 0.5% faster MBAFF loop filtering
Make the jump-table section-relative for x86_64 with PIC enabled. This allows to get rid of the macho64 specific hack that moves them to rodata (with worse cache behaviour) and avoids textrels which e.g. Gentoo does not allow for x86_64 libraries.
Use av_get_pix_fmt() instead of the deprecated avcodec_get_pix_fmt() function.
Remove duplicated word in av_strlcat() doxy.
Add missing '()' at the end of a function name.

Indeo Video Interactive 4 and 5 common code and DSP functions. Reviewed and corrected by myself because there were no other volunteers in the last weeks.
Revert commits 21227, 21441, and 21442. None of this is necessary now that we load the getaddrinfo family of functions through GetProcAddress. Also, there is currently no feature that gets fixed in Win98 through the use of KernelEx.
Make VP5 and VP6 decoders output a qscale table to allow for more automatic post-processing, and add a new FF_QSCALE_TYPE_VP56 for this.

Move ECFLAGS so it doesn't get added multiple times
Simplify error handling by processing header errors separate from CRC and buffer size vs. frame size errors.
Move variable declaration to block where it is used and simplify code. Avoids a (incorrect) "possibly used uninitialized" warning, no measurable speed difference.
Export H264 profile and level in AVCodecContext.
Extract duplicated code into a separate function. 5% faster on Intel Atom with gcc 4.4.1 (performance is unchanged if using av_always_inline).

Simplify. See "[PATCH] simplify ff_set_fixed_vector()" thread on mailinglist.
Add --malloc-prefix to apply a prefix to malloc, free etc
Initialize thread_context[0] with h264 parser context. This allows freeing the parser memory in the thread_context freeing loop.
Change wraper functions to always inline, they are faster now that way. 1% faster MBAFF decoding overall, maybe ~0.1% faster for the cathedral sample.

Restructure check_mv() ~20 cpu cycles faster loopfilter
Restructure if() in check_mv() quite a bit faster
Unroll loops in check_mv() ~6% faster (slow path) loopfilter (should be ~2% overall)
Factor mv/ref compare code out. This is a hair slower (0.15% maybe) but i really dont want to have the identical code duplicated 3 times because gcc adds odd threaded jumps with register reshuffling and register safe/restore.
Use av_mallocz in url_open_protocol for URLContext. Patch by Daniel Kristjansson: danielk cuymedia net
Remove last MAX_STREAMS from avienc.c
configure: consolidate compiler-specific optimisation settings
Introduce AVIStream struct and move stream based variables to it. This removes all but one MAX_STREAM from avienc.c.
Simplify first edge filter condition.
Cosmetics, mostly indention, 2 or so new fixme comments that i was to lazy to split out
Make the fast loop filter path work with unavailable left MBs. This prevents the issue with having to switch between slow and fast code paths in each row. 0.5% faster loopfilter for cathedral
get rid of the start variable. a few cycles faster
Unroll main loop so the edge==0 case is seperate. This allows many things to be simplified away. h264 decoder is overall 1% faster with a mbaff sample and 0.1% slower with the cathedral sample, probably because the slow loop filter code must be loaded into the code cache for each first MB of each row but isnt used for the following MBs.
Declare variable "version" in the PRINT_LIB_VERSION() macro if block, slightly simpler and more robust.
Support demuxing Blu-ray subtitles in matroska files.
Fix BSD compile (PF_UNSPEC is not a standard define, AF_UNSPEC is).
Fix svq3_* function declarations.
SVQ1: 4-byte-align codebook tables
Fix possible crashes in mlp parser, it tries to go back 7 bytes after finding the 4-byte signature. Add a check that ignores the signature if we do not have enough previous data to go back at least 7 bytes.
Reduce log level of "Extracting .. channel downmix" to AV_LOG_DEBUG, the message is pointless to ordinary users and is printed once per frame.

Moved reusable functions from dxva2_h264.c to dxva2.c
Move +52 from the loop filter to the alpha/beta offsets in the context. This should fix a segfault, also it might be faster on systems where the +52 wasnt free.
Release buffer when the codec is closed.
Use qstride = 0 and allocate only a single line for qscale_table since for this codecs all quants are the same for a single frame.

Reindent the content of one if(){} in ff_dxva2_common_end_frame.
Moved reusable code from dxva2_h264.c:end_frame to ff_dxva2_common_end_frame.
Set edges based on cbp and mv partitioning, not just skiped MBs. This is faster for videos that have lots of MBs that fall in this category.
Use AVPALETTE_COUNT instead of hard-coding 256. This is consistent with other codecs and will also avoid a crash on the memcpy to data[1] if AVPALETTE_SIZE ever increases.
Remove redundant initialization of the palette, it is part of the context and that one is always 0-initialized already.
Optimize filter_mb_mbaff_edge*()
Optmize 8x8dct check used to skip some borders in the loop filter. 4 cpu cycles faster.

Gcc idiocy fixes related to filter_mb_edge*. Change order of operands as gcc uses a hardcoded register per operand it seems even for static functions thus reducing unneeded moved (now functions try to pass the same argument in the same spot). Change signed int to unsigned int for array indexes as signed requires signed extension while unsigned is free. move the +52 up and merge it where it will end as a lea instruction, gcc always splits the 52 out there turning the free +52 into an expensive one otherwise. The changed code becomes a little faster.

Disable a few things in fill_filter_caches() that arent needed. 0.1% speedup
Split fill_caches() between filter and decoder.
Rearchitecturing the stiched up goose part 1 Run loop filter per row instead of per MB, this also should make it much easier to switch to per frame filtering and also doing so in a seperate thread in the future if some volunteer wants to try. Overall decoding speedup of 1.7% (single thread on pentium dual / cathedral sample) This change also allows some optimizations to be tried that would not have been possible before.

Split motion vector prediction off h264.c/h.
Move check_intra4x4_pred_mode() back from h264.h to h264.c, the function is just called once per MB in worst case and doesnt seem to benefit from static inline. Actually the code might be a hair faster now (0.1% according to my benchmark but this could be random noise)

Move svq3.o to the correct spot.
Get rid of #include "svq3.c" functions called more than per mb are moved into the header, scan8 is also as it must be known at compiletime. The code after this patch duplicates h264data.h, this has been done to minimize the changes in this step and allow more fine grained benchmarking. Speedwise this is 1% faster on my pentium dual core with diegos cursed cathedral sample.

More sane error message when extradata has not been set.
Swap red and blue when decoding r210.
It appears that waveformatextensible is mandatory for more cases than just channels>2. The 16bit case is from MSDN, the 48khz is from less a reliable www page (sorry i cant find the URL anymore).

Correct typo
10l: Don't spawn a subshell when disabling vdpau.
Revert  flvdec.c part of r20836 	Log: 	Use AV_METADATA_DONT_STRDUP* / use av_malloced metadata instead of strduped 	arrays of fixed length. 	Code from ffmbc with changes to adapt to our metadata API. Reason: memleak & fix is not trivial
Include dup/drop info if any frames where duplicated or droped instead of when verbose>1. From ffmbc0.3
Off by 1 bugfix for nb_frames_dup. From ffmbc0.3
Merge init & declaration of buf_end. From ffmbc0.3
Set reordered_opaque in default_reget_buffer() with internal buffers. From ffmbc0.3, this one appears to be a bugfix.
Check sample_aspect_ratio validity for mpeg4/h263/h263p encoding. Merged from ffmbc0.3
Use PIX_FMT_NONE for -1 when enum PixelFormat is expected (fixes two icc warnings).
Use enum PixelFormat as type for input_pixfmt to avoid one icc warning.
Support compressed formats in the V4L2 input device. Patch by klchxbec AT freenet DOT de.
Add support for V4L2 compressed formats in the table used for converting between V4L2 formats and ffmpeg's formats/codecs. Patch by klchxbec AT freenet DOT de.
Use the correct type for the V4L2 format.

Disable vdpau support if the detected libvdpau does not support MPEG-4.
FLV 8-bit PCM is unsigned, not signed
Factorize ic->streams[i] out, change from ffmbc

Make sure the Metadata: header is not printed if the only metadata will not be displayed. (idea from ffmbc)
Move dump_metadata() to where it is in ffmbc, looks better.
indent
Skip dumping language twice. This looks too ugly. Idea also from ffmbc.
dump metadata for AVStreams & AVPrograms too.
Factorize dump_metadata() out. Idea from ffmbc, code not, mine is a fraction of the size due to simpler metadata API.

add av_metadata_set2(), AV_METADATA_DONT_STRDUP_KEY and AV_METADATA_DONT_STRDUP_VAL
Add flags to prevent strdup() on arguments to av_metadata_set2(). I cannot use the same ABI as ffmbc as value 2 is already used in ffmpeg, besides the name AV_METADATA_NONCONST* makes no sense to me. Add av_metadata_set2() that takes flags.
Until -DHAVE_AV_CONFIG_H is removed from ffplays compilation, *printf must be #undef. Without this random changes to the header inclusion can trigger linking failures, and these are not even picked up in some environments (some fate machines didnt catch it).
Move #include where it belongs. This as a sideeffect fixes the linking failure of ffplay.
Get rid of useless casts.
APIchanges update for av_d2str()
Add a function to convert a number to a av_malloced string.

Read and decode block data in separate functions to prepare support for multi-channel correlation mode.
Use constant CODEC_ID_NONE instead of 0 where appropriate.
Remove commented out code.
Show help if no cmd line options are provided at all. This safes the users time to find out which of -h --help -? works.
Factor out extradata reading code. Borrowed from RM demuxer in FFmbc.
RM audio stream version should be 16-bit followed by header size or reserved word, so treat it this way instead of extracting different parts from 32-bit value.
Make RM demuxer look more like proper demuxer by introducing codec tags instead of many strcmp() on always four-byte strings. Idea borrowed from RM demuxer in FFmbc by Baptiste Coudurier.
Factor out variable declaration

refactor and optimize scalarproduct 29-105% faster apply_filter, 6-90% faster ape decoding on core2 (Any x86 other than core2 probably gets much less, since this is mostly due to ssse3 cachesplit avoidance and I haven't written the full gamut of other cachesplit modes.) 9-123% faster ape decoding on G4.
Fix compilation with runtime cpu detection. All functions in swscale_template.c should be declared with the RENAME macro.

Set the SBR mode to implicit on ADTS frames occurring before the output is locked.
Small refactoring: Instead of 4 loops for decoding AC coefficients based on their grouping, create one loop that indexes into a table of AC VLC tables.
Use a list to track which fragments coded in this frame still have outstanding coefficients yet to be decoded from the bitstream. Once a fragment reaches end-of-block, remove it from this new list. This change makes the VP3/Theora entropy decode process dramatically faster due to not having to iterate incessantly over fragments which have already been fully decoded.

Pass only useful FLV metadata from RTMP stream
Update dimensions in AVCodecContext when RV3/4 frame dimensions change
Do not write an extra byte in the iTunes 'hdlr' tag.  The files on iTMS have an extra byte and are not compliant with ISO 14496-12.  This causes some strict demuxers (notably the MPEG-4 ALS reference software) to fail.  It has been confirmed that not writing the extra byte will still allow the generated MP4 files to work with QuickTime/iTunes/iPod.

Handle JPEG2000 frames stored in the Quicktime container. Fixes issue 1525.
cosmetics : fix indentation.
Remove code checking for __PIC__ or __pic__ and setting PIC from libavutil/internal.h, configure is supposed to take care of that already.
Check if PIC is somehow already enabled (e.g. a compiler that enables it by default). This in particular ensures that -DPIC is set appropriately for YASM, which avoids linking failures on x86_64 for compilers that have PIE enabled by default (e.g. hardened Gentoo). It also makes the macho64 special-case hack adding -DPIC to YASMFLAGS obsolete.
Avoid variable-length array use in ff_acelp_lspd2lpc()
Add a NULL pointer check to avcodec_close() this should prevent a segfault when closing without open.
configure: whitespace cosmetics
patcheck: check that pix_fmt etc. initializers are const
fix a rounding error in the PSNR calculation and update the many regression test references that this change affects.
Attempt to document the "enable pic" hackery for OpenBSD.
Make get_bits_left() available for use in libavcodec (was previously held private in dv.c for some reason). See "[PATCH] get_bits_left()" thread.
And on the sixth day, God gave us the <= operand, which makes the loop "for (i = 1; i < num + 1; i++)" look like "for (i = 1; i <= num; i++)". Programmers worldwide rejoiced and used the operand, e.g. in the thread "[PATCH] remove ugliness in cel_filters.c", and He saw that it was good.
Fix crop filter start_frame() for paletted formats different from PAL8. Shift data[1] only if the input format is not paletted.
Enable linking of parseutils.o.
Remove some BeOS/haiku hacks: -fomit-frame-pointer is used anyway, and -DPIC makes little sense without -fPIC or similar - if -fPIC is enabled by default, libavutil/internal.h defines PICi anyway.
Do not hardcode filter order in ff_acelp_lspd2lpc()
Move ff_reverse in libavcodec to av_reverse in libavutil.
Increase default value for max_analyze_duration, fixes issue 1506, a regression.

Fix start_frame(), which was issuing chroma artifacts with planar formats with more than 8 bits per pixel (e.g. YUVXXXP16).
Set -DPREFIX for yasm simply whenever extern_prefix is set instead of hardcoding it based on the object format.
Remove unused variable. 1l for me if it wherent sunday and i could buy cola.
Always add -DPIC to YASM flags when pic is enabled. This covers the previous case of x86_64 and shared, but also works with --enable-pic. For 32 bit x86 it currently makes no difference since x86inc.asm ignores -DPIC for non-x86_64.

Reduce stack memory allocation in MP3 decoder
Implement ff_scale_vector_to_given_sum_of_squares() to aid generic gain control routines. Changes for qcelp are included. Patch Collin McQuillan.
Pad ff_cos_tabs and ff_sin_tabs so that index n points to the table for n bits. While this "wastes" up to 2x32 bytes it makes the code slightly simpler and less confusing.
Don't lock the channel output configuration based on the first value seen for non extradata formats. Instead lock it only after the successful decoding of a frame. This fixes issue 999.
Vertical align.
Use spaces after commas for improving readability.
Add slicify video filter.

Enable hardcoded tables for ia64 shared builds. At least for cross-compilation with Gentoo gcc 4.4.2 it fixes the build errors due to GPREL 22 being insufficient for the .bss size of > 4 MB without it. Why these errors do not appear with static builds is unclear, it is not due to PIC (shared builds with PIC disabled show the same issue).

Add comment on #endif about condition that triggers it.
Seek function for TMV
Parenthesize correctly in TMV probe

Split parts of dvdata.h into dvdata.c, this ensures that things like work_chunks_* and dv_idct_factor_* variables appear only once in the binary instead of 3 times. Saves 3264 bytes in .rodata and 312416 bytes in .bss on x86_64.
Add Speex support to the FLV muxer.
Add support for hardcoded ff_sin_* tables.
Move/add COSTABLE/SINTABLE macros to dsputil to add extern definitions for ff_cos_* and ff_sin_* without introducing too much code duplication.
Remove silly casts to the same type as we already have.
Add missing release_buffer at decode end for asv1 decoder.
Partially revert r20233, exp2f is not available on some BSDs, DOS and AVR32.
Raise MAX_THREADS to 16.
Skip padding bytes correctly in ID3 tags. This fixes a regression introduced in r20170.
Do not initialize ff_cos_* tables again in rdft_init, they are already initialized by ff_fft_init and using different code can result in slightly different values, in addition it crashes when the tables are hardcoded. On amd64 this slightly changes qdm2 output.
10l: update Makefile after rename
Rename aiff.c to aiffdec.c
Split up the AIFF muxer and demuxer into separate files.
Use cbrtf and exp2f instead of pow to calculate tables for MPEG audio decoding. This hopefully is fast enough so that it is reasonable to use the same formula directly instead of the table for CONFIG_SMALL.
Use hardcoded instead of runtime-calculated ff_cos_* tables if --enable-hardcoded-tables was used. Due to the size, the code for the tables is generated at compile time.
Release frame after decoding is done
Print a warning message when avcodec_default_free_buffers finds unreleased buffers, this hopefully should help detect codecs that do not release all buffers e.g. in the decode_end function.
Remove unnecessary calls to avcodec_check_dimensions, the check is already done at a higher level.
Call release_buffer on close for v210dec and v210x
Add missing release_buffer on close

Do not read data past the end of the SSND chunk in the AIFF demuxer. Fixes Issue 1455.
Support Midvid JPEG Video Codec (still flipped).
Support Intel JPEG Library Video Codec (still flipped).
Calculate correct packet durations when demuxing Ogg/Speex. This involves determining if there is any delay in the first packet and/or any truncation in the final packet.

Reindent after removing the outer for loops in the execute2 patch
Move dnxhdenc to execute2 multithreading API. This allows for some simplifications like removing some outer loops and gives much better performance for thread_count > number of idle CPUs.
Add an execute2 function that is more flexible and allows to use parallel processing with jobs > threads without wasting too much memory. It also avoids needing a separate int array when the only additional data the jobs needs is a single int running from 0 to count-1.

Hack: set the coded frame PTS to the incoming PTS. This is not correct, but libtheora does not seem to provide a way to get the correct value, and this is necessary to make encoding produce sensible time stamps when encoded content is variable FPS or the time base is simply different from FPS. Somewhat fixes issue 1197.

wav demuxer: return AVERROR_EOF instead of AVERROR(EIO) when the end of the file is reached normally, without any error.
wav: return av_get_packet errors unchanged.
Fix seek regression test: several AVERROR(EIO) correctly changed to AVERROR_EOF.
Remove url_feof check that would be triggered only after incorrectly producing an empty packet and also av_get_packet already handles EOF now.
Remove useless setting of pkt->size, av_get_packet already handles that.
Return special EOF checking for aiff and au demuxers, the check was at the wrong place, causing an empty packet to be read before EOF was detected and the eof detection is already now handled by av_get_packet anyway.
Return any error return values from av_get_packet, get_buffer etc. unchanged in the raw demuxers. Also remove special handling of 0-size reads, if they are due to an error/eof, these are already converted to the appropriate error by get_buffer.
Make seek regression tests fit after previous get_buffer change. The au and aiff demuxers would always return an empty packet before detecting EOF, this is now fixed with av_get_packet etc. returning EOF.
Make get_buffer and get_partial_buffer return url_ferror or AVERROR_EOF as appropriate if it couldn't read any data at all. This should make handling of EOF and error simpler or make it work right without extra code in a few place (e.g. raw demuxer).

au demuxer: pass av_get_packet error on unchanged instead of converting to AVERROR(EIO).
av_new_packet failing should return ENOMEM, not EIO.
Make avcodec_open set codec_id and codec_type if they haven't been set. This fixes the API breakage introduced by the check that avctx codec id and type match the opened codec and should make (almost?) all applications work again.
put_bits can only reliably write up to 31 bit bits, above it relies on undefined shift behaviour. Document this, fix the assert and add a put_bits32 to handle writing 32 bits and use that where necessary.

Re-add check for compilation failure with ebx clobber, and only set ebx_available if both "b" constraint and exb clobber code compile. This is to fix compilation with Mac OSX 10.5.8's gcc 4.0.1 in 64 bit mode (-m64) which only fails for ebx/rbx clobbers but not "b" constraints - this is probably a compiler bug.

Use skip_put_bytes in MJPEG encoder instead of filling all bytes with 0 with put_bits.
Use ff_put_string in vorbis encoder.
Replace several #ifdef PIC with the more obvious and correct #if !HAVE_EBX_AVAILABLE, since all it does is avoid using ebx.
Disable parsing for ogg streams where no ogg header was found, if no header was found the parser was not initialized and thus will crash when trying to use it.
Convert latin1 codec_name in mov to UTF-8, since all strings in FFmpeg must be valid UTF-8.
When BitsPerSample tag is not present in TIFF, that means file is monochrome, so initialize picture before decoding. This fixes decoding monochrome files produced by lavc TIFF encoder.
Simplify stereo rematrixing by only using one temporary variable. It is also about 1.8% faster on my system.
remove unneeded assignment in inner loop. rematrixing bands are contiguous.
Prefer -vcodec rawvideo over -vcodec huffyuv for lavfi regression tests, as the use of huffyuv may cause the auto-insertion of a scale filter, thus masking the mis-behavior of some filter.

Sync AC3 probe values with MP3 probe values, they have to avoid similar issues. This fixes ffmpeg-generated files with -acodec ac3 being detected as raw ac3 instead of MPEG.
Extend DV autodetection to also reliably detect single-frame DVs with a higher score that MAX/4. It checks that there are at least 10 DIF headers and at least one per 24000 bytes, and if so considers the file reliably detected as DV. Passes probetest, too.
Add id3v2 metadata conversion table and use it in mp3 muxer.

Specify maximum sample rate of MLP by defining the factor relative to 48000 instead of directly.

Check if a git-svn revision number is available to try to get better version information from git.
Fix possible buffer over-read in vorbis_comment, fix it double to be sure. First, make s signed, so that comparisons against end - p will not be made as unsigned, making the check incorrectly pass if p is beyond end. Also ensure that p will never be > end, so the code is correct also if buf is not padded.
Completely remove INIT_VLC_USE_STATIC, it is deprecated since ages and finally no longer used anywhere.
Replace last use of INIT_VLC_USE_STATIC by INIT_VLC_USE_NEW_STATIC in svq1dec
Change VLC table creation in x8_vlc_init to use INIT_VLC_USE_NEW_STATIC.
Use ff_msmpeg4_decode_init to initialize ff_msmp4_mb_i_vlc since static VLC tables should only be initialized from one place. This initializes/calculates more VLC tables than necessary for VC1 decoding, but this is only done once and only a small overhead in time and space (maybe 30 kB) it seems not worth adding a separate function.
Use INIT_VLC_STATIC where easily possible in svq1dec

Make MPC SV8 probe skip tags until stream header is found
Monkey's Audio uses subframes too, declare that in its capabilities
Fix overflow check insufficiently improved in r19840. It assumes that sizeof(vmd_frame) < 64k, otherwise an additional check to ensure sound_buffers <= UINT_MAX / sizeof(vmd_frame) would be necessary.

Probetest, to test the demuxers probe functions against random and not so random input.
Slightly stricter MPEG-PES probing, fixes issue 1383.
Vastly improved mm_probe function, passes probetest.
Improve sierravmd probe. It is still quite weak, but further improvements are non-obvious and probably need a large (about 1kB at least) probe buffer.
Slighty tweak mp3 probe threshold to prevent probetest from complaining.
Try harder to avoid false positives for DV probe. Require at least one signature match per provided 1MB of probe data, and if there is only a single match, return at most MAX/4. Fixes issue1382 but could/should probably still be improved.
Make dnxhd probe more strict, fail if we detect values in header that would make our decoder fail anyway. dnxhd probe now passes probetest.
ARM: 10l: fix large FFTs
Rewrite h261_probe(). New code can detect h261 startcodes even when the first is damaged or not at the begin. It also passes probetest v2 & v3.
Make DTS probe more robust against false positives (as e.g. probetest shows). In particular check that the detected markers clearly indicate a specific DTS format (a wild mixture of e.g. little- and big-endian markers is unlikely to be a valid DTS file) and ensure the markers appear with sufficient frequency.
Check the index validity more thoroughly for the c93 probe function. In particular, check that length of the first index entries is not 0 since that is interpreted "end of file" and makes no sense in the very first entries.
Add more sanity checks for header elements, rejecting files with clearly invalid values that wouldn't play right anyway and reduce probe score to MAX/2. Passes probetest v2.
Rewrite h263_probe(). The new code should detect h263 even if the first startcode is damaged or somewhere else than the first byte. It also passes probetest v2 as just posted on ffmpeg-dev.
Extend check for integer overflow for malloc argument to take into account also the addition of "sound_buffers" not only the multiplication.
Fix wrong logical operator which causes too relaxed checking in VC-1 test format probe. Spotted by Reimar Döffinger.
Check buffer size for idcin check, otherwise false positives are too likely for small probe buffer sizes due to 0-padding (see probetest results).
Update preset files to jive somewhat better with more recent x264 API.

When resetting vst->pkt.data to NULL, also set vst->slices. This avoids a crash when the next slice is not a start slice and thus pkt->data is still NULL. This probably only happens with broken or unsupported files like http://samples.mplayerhq.hu/real/multirate/JustaSpa1937_64kb.rm that need further fixes, but keeping vst state consistent is still a good idea.

Remove fake Speex header creation from FLV demuxer.  Having it there was not the correct solution to the problem.  A better solution might be possible later once Speex is supported in muxers.
Add frame_size as a codec parameter requirement for Speex in av_find_stream_info().  It forces decoding of a packet when there is no Speex header in order to determine the correct frame size.

Convert ZERO8x2 macro into inline function
Remove unused variable.
Zeroing pic->motion_val in RV3/4 causes alignment problems on some 64-bit architectures since stride is multiple of 4 and not of 8, so split fill_rectangle() calls to operate on 32-bit words instead of 64-bit ones.
Adjust r->avail_cache[] indexes to avoid alignment issues when zeroing block inside it.
Curly brackets cosmetics for previous commit.
Check for return value of initFilter().

Mark parameter src of vector_clipf() as const
SSE optimized vector_clipf(). 10% faster TwinVQ decoding.
indent
1.5x faster ff_vorbis_floor1_render_list, 5% faster vorbis decoding on Core2. 1.3x and 3% on G4. Though I think only part of this speedup is due to my optimizations per se; some of it is that I got a better roll on the GCC random code generator. Trivial reorderings of this function have a disproportionate effect on speed.

100l typo, xsub encoder printed end time hours where minutes should have been.
100l, inv_zigzag_direct16 must be aligned to 16 bytes for dct_quantize_SSE2 (which uses movdqa to xmm1 on inv_zigzag_direct16).
Make sure that start_display_time is 0 by moving its value onto pts. If it was not 0, subtitle encoding would fail.
Check for seek failures in avi_load_index, otherwise if the index offset is invalid (e.g. truncated file) we might end up reading the whole file since trying to seek beyond the end of file does not set EOF.
Reindent.
Remove now dead code.

However, that was separated out into a new function, and the flags/timestamp are thus never updated within ff_rm_parse_packet() anymore, and thus do not need to be a pointer.

Remove dependency from swscale_internal.h to lavu/internal.h, it is no longer needed for DECLARE_ALIGNED. Remove dependency from swscale-example.c to swscale_internal.h by duplicating the necessary code. The duplicated code is a hack and should be removed once a cleaner pixel format information system exists. swscale-example.c is example code on how to use the library and therefore shouldn't rely on internal headers.
Move DECLARE_ALIGNED and DECLARE_ASM_CONST back from lavu/internal.h to lavu/mem.h.
Do not throw compiler error if asm code needs alignment, but we do not know how to do it for this compiler. This removes a dependency of config.h on the DECLARE_* macros.

whitespace cosmetics: Realign colums after last commit.
Check for CONFIG_LIBFOO_DECODER/CONFIG_LIBFOO_ENCODER instead of just CONFIG_LIBFOO in the external libraries section. This is more consistent with the rest of the Makefiles, it makes clearer what is actually implemented and should be advantageous if we implement an external library encoder where we previously just had the decoder and vice versa.
Remove support for nonfree libamr library for AMR-NB/WB decoding/encoding. libopencore can now be used as a replacement except for AMR-WB encoding.

Remove useless ret variable added in last revision again.
100l, theora_decode_init must pass on errors from vp3_decode_init
Make decode_init fail if the huffman tables are invalid and thus init_vlc fails. Otherwise this will crash during decoding because the vlc tables are NULL. Partially fixes ogv/smclock.ogv.1.101.ogv from issue 1240.
Do not fail if 'uuid' atom is encountered before 'moov'. Patch by Frank Barchard, fbarchard at google dot com.
libfaac no longer claims to be LGPL.

Ensure that the filter limit values do not exceed the maximum allowed value of 127.
Extend init_loop_filter to work for filter limit values up to 127 instead of only up to 64. 127 is the maximum value allowed by the theora specification.
Add a check to vp6_parse_coeff_huffman to ensure it does not overread the input buffer.
vp56dec: ensure range coder won't read past the end of input buffer
Check that palctrl is available on init instead of crashing when trying to use it on decode. Fixes mpeg2/smclockmpeg2.avi.2.1 from issue 1240.

ARM: NEON VP3 IDCT 15% faster VP3/Theora, 10% faster VP6
If the end of the input buffer is reached while decoding MJPEG and at least a valid SOF was found, emulate an EOI. This allows e.g. to at least decode the available part of incomplete MJPEG frames.
Make the MJPEG decoder return -1 when no image was decoded so that decode errors are actually recognizable as such.
Add a got_picture flag to MJpegDecodeContext which indicates if its picture element is valid. Skip the code handling SOS and EOI if not, since it can not work without a valid AVPicture. This fixes a crash with mjpeg/smclockmjpeg.avi.1.0 from issue 1240 where the decoder returned an invalid AVPicture.
mjpegdec: check that the coded dc_index and ac_index have a valid associated VLC table. Removes some disabled dc_index/ac_index checking code that seems to have had some undocumented issues and should not really be necessary anymore now. Fixes from issue 1240 the files mjpeg/smclockmjpeg.avi.1.10 and mjpeg/smclockmjpeg.avi.1.171.

Rewrite mp3 parser. New code is much simpler and does not drop stuff at random.
Use av_log_missing_feature in the ADTS encoder. (Pseudo reverts r19173).

mov demuxer: Track the current position also for streams that have AVDISCARD_ALL set. This allows for seamless switching of e.g. audio streams, with the previous code playback started always from the beginning when removing AVDISCARD_ALL.
mov_read_packet: extract code that searches for the stream/sample to demux next into a separate function.
mov_read_packet: if dv_get_packet fails, return exactly its error value instead of always -1 (makes no real difference currently since dv_get_packet always returns -1 so far).
In mov_read_packet remember the AVStream we want to demux next instead of the MOVStreamContext. We need the AVStream anyway and it is easier to get the MOVStreamContext from the AVStream than the other way around.

Do not guess the channel layout when getting its string value.
matroskadec: prepend TargetType to metadata key name
Remove the 3-front-channel layout from the list of channel layout aliases.  Calling this "surround" is confusing and questionable.
Correct reading bits in MPC SV8 base codes (when we have to read 0 or >16 bits).
Allocate a bit more memory for MPC SV8 seek table, so bitreader won't read beyond allocated block.
Analysis of logs show that there are in fact some files with m1v1 too (not just m2v2), which is documented to be MPEG-1 video.  Adding fourcc to isom.c.
Electronic Arts demuxer: support Madcow video tag
Electronic Arts Madcow decoder
Also accept TS as a prefix for wav twoccs (used by Flip4Mac) instead of adding entries to codec_movaudio_tags. This ensures ADPCM_IMA_WAV uses the standard ms prefix when muxing to mov rather than TS.
Add "0x11005354" as a fourcc for MOV audio; fixes audio detection in a problematic MOV file. The audio is actually adpcm_ima_wav.

Add sac3 to mp4 fourccs for mov+h264+aac-sac3+mp4s+ETERNAL_cut.mp4
Add "m2v1" to fourccs for MPEG-2 video; fixes some MOV files.
Fix cast of byte buffer to uint32 that was disregarding alignment requirements. Now calculates crc byte at a time until aligned, then continues with uint32 optimized calculation. This fixes crashes during mlp decoding on sparc (at least, maybe others).

cosmetics: Reformat file to K&R style upon Kostya's request.
10l: Add vc1dec.o to the list of WMV3 objects, same as for VC-1. Even after the split into shared and decoder-specific code, WMV3 continues to have the same dependencies as VC-1.
Split decoder-specific code off from vc1.c into vc1dec.c and keep code shared between decoder and parser in vc1.c.
Add const in cast. Removes warning: libavcodec/resample.c:215: warning: assignment discards qualifiers from pointer target type

Disable native Vorbis encoder; quality is much worse than libvorbis and there really isn't a reason to use it on purpose unless you're improving it.
Remove time_rate, we cannot compute exactly when fragments are used and we cannot determine if fragments are present or not in streamed mode.
if b frames are parsed, set codec->has_b_frames
Remove even condition on pad and crop. Odd padding or cropping is needed when encoders only support even resolution.
Add code to enable and disable all VAAPI and VDPAU parts. As a positive sideeffect, VAAPI/VDPAU objects need no longer be listed for all VAAPI/VDPAU-related decoders.

Change maskbit variable to contain (1 << maskbit)
Remove check that thanks to padding is no longer necessary.
100l, the compression field in lcl extradata must be interpreted as int8_t, not uint8_t to allow -1 for "no compression". The original code worked, but only when char was signed.
One more use for FFMIN.

lcldec.c: change #if CONFIG_ZLIB to #if CONFIG_ZLIB_DECODER. The zlib related code should not be compiled in when the decoder is disabled and it thus will never be used, even if we have zlib available.
Get rid of extradata casts, it already has the right uint8_t * type
Make lcldec produce YUV output when the input file is coded like that, instead of having it do its own inefficient fixed-point YUV to RGB conversion.

Merge decoding functions for all bitdepths in WavPack decoder
Support >8bit per component YUV in FFV1. decoding becomes slower, encoding becomes faster, with gcc on duron. some inlining overrides like av_flatten are added to keep inlining similar to before.
Force speed irrelevant calls to get/put_symbol() to be noinline. We need to change decode_line to always_inline because gcc decided not to inline it anymore once we force some calls to get/put_symbol() to be non inlined and this decision of gcc would lead to a 10% overall speed loss. 100k smaller object file, no speed change
Optimize sign handling in get_symbol().
Don't loose bits_per_raw_sample when transcoding.

win32, dos: Work around a bug in the GNU toolchain. The bug[1] is exposed when gcc decides to put some data in a common section (i.e. data that will be used by more than one object). It will suggest the data to be aligned, but binutils >= 2.19 will fail to properly align it. Thus if the data requires any alignment greater than 4, the application will crash. The workaround prevents gcc from putting data in a common section, instead putting it in a properly aligned section.

fix vp5/vp6 decoding by using new prototype for decode function
Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames.
Move AVPacket up a bit, so that structs/functions that include AVPacket can themselves be reasonably positioned.

Move output_example.c --> libavformat/output-example.c. The libavformat directory is a better place for a libavformat API example.
Make static the list of registered filters.
Remove unnecessary CFLAGS variable from output_example link command.
Removing example programs is already handled by the generic clean commands, so there is no need to remove output_example individually.
Rename cs_test.c --> colorspace-test.c.  This is more consistent with the names of other test programs and more descriptive of what the program does.
Fix a warning on an uninitialized variable.
Use a wildcard match instead of a list to remove test programs. This is robust against renames and also removes test programs not (yet) hooked up in the main Makefiles.

Fix some places where "non-alpha to YUVA420P" do not fill the alpha plane
Simpler and more elegant fix to the x86_32/OSX+PIC build failure
strchr(string, '\0') returns non-NULL, and is thus not suited for use in redir_isspace(char) to check if '\0' is a space or not. Therefore, we now use memchr(), since then we can give the length of the string (i.e. the length excluding the terminating '\0'). Fixes issue 919, see also the follow-ups in the "[PATCH] rtsp.c small cleanups" mailinglist thread.
Update apiexample.c to use the newer avcodec_decode_audio2() API. This also fixes compilation.

Extend the behavior of avcodec_get_pix_fmt(), if it cannot find a pixel format for the provided name, make it look for the native endian variant of the name.
Globally prefer enum PixelFormat over int when it makes sense.
Remove slash-skipping code because the function called right after that statement (get_word_sep()) already does that all by itself. See summary in "[PATCH] rtsp.c small cleanups" thread on mailinglist.

Fix silly bug in hex_to_data() where it compares a string pointer for whether it is '\0' rather than its content (char *p; if (p == '\0') instead of if (*p == '\0')). See summary in "[PATCH] rtsp.c small cleanups" thread on mailinglist.
Remove useless comment about something that is deprecated. See summary in "[PATCH] rtsp.c small cleanups" thread on mailinglist.
Use skip_spaces() in the "redir" demuxer instead of "while (isspace(&p)) p++". See summary in "[PATCH] rtsp.c small cleanups" thread on mailinglist.
Merge functional code from get_word() and get_word_sep() into a single function, since they both do approximately the same thing. At the same time, remove redir_isspace() altogether since code elsewhere (including get_word_sep()) uses strchr() for the same purpose. See summary in "[PATCH] rtsp.c small cleanups" thread.
Allow (and parse) incoming server messages (notices) interleaved with TCP data packets or in addition to UDP data packets, over the RTSP/TCP connection. See discussion in [PATCH] rtsp.c: read TCP server notifications/messages" thread on mailinglist.
Add a @todo item to use ByteIOContext instead of URLContext at some point in the future, requested by Luca in "[PATCH] rtsp.c: read TCP server notifications/messages" thread.

Prevent (negative) overflow of rm->remaining_len. This evaluation really only has two possible outcomes: either len and rm->remaining_len are the same, in which case we care about the outcome and it is zero, or rm->remaining_len is currently not in use and we don't care about the outcome. In that case, len is positive and rm->remaining_len is zero, which leads to a negative result. This is confusing and could eventually lead to a sign-flip if we skip a lot of packets (unlikely, but still). Therefore, just always set it to zero.

Remove size_t cast in setting s->priv_data directly to the (integer) file descriptor returned by open(). This removes some dubious doublecasts such as priv_data = (void *) (size_t) some_integer, and is always safe on systems we care about because sizeof(int)<=sizeof(void*). See comments from Mans and Michael in "[RFC] rtsp.c EOF support" thread.
Don't let finalize_packet() touch pkt->stream_index. Instead, let individual payload handlers take care of that themselves at their own option. What this patch really does is "fix" a bug in MS-RTSP protocol where incoming packets are always coming in over the connection (UDP) or interleave-id (TCP) of the stream-id of the first ASF packet in the RTP packet. However, RTP packets may contain multiple ASF packets (and usually do, from what I can see), and therefore this leads to playback bugs. The intended stream-id per ASF packet is given in the respective ASF packet header. The ASF demuxer will correctly read this and set pkt->stream_index, but since the "stream" parameter can not be known to rtpdec.c or any of the RTP/RTSP code, the "st" parameter in all these functions is basically invalid. Therefore, using st->id as pkt->stream_index leads to various playback bugs. The result of this patch is that pkt->stream_index is left untouched for RTP/ASF (and possibly for other payloads that have similar behaviour).
Set PixFmtInfo::{x, y}_chroma_shift for VDPAU and VAAPI formats.
Reindent after r17764.
In the current implementation of rtp_parse_packet(), finalize_packet() is called for all packets with an internal handler function but only for non-first packets from dynamic payload parse_packet() handlers.

Factor out block decoding in ff_h263_decode_mb()
Consider all packets in the parser, not just ones with timestamps, this should greatly simplify handling of packet pos.
Favor container packets that end after the first byte of the access unit in fetch_timestamp(). This should make no difference for valid streams but may help invalid ones, also its needed for future changes.
Call ff_fetch_timestamp() for mpeg1/2 when a picture start code is found instead of calling it at the end of a frame with a large negative offset. This significantly reduces the maximal distance in container packets between the point where the first byte of the "access unit" was stored and where we call ff_fetch_timestamp() thus reducing the constraints on our parser. Also change the parser from next_frame_offset to cur, this is needed because now the reference is from container packet start instead of frame start. (i previously misinterpreted this as bug)
version.h should depend on config.mak. The extra version string that is passed to configure is recorded in config.mak and changes to config.mak can therefore make version.h rebuilds necessary.

Fix doxy comments missing one '*'.
Use the "server" RTSP field to detect whether the server that we're talking to is a Microsoft Windows Media Server (the field will be "WMServer/version"). See "[PATCH] RTSP-MS 3/15: Add Windows Media Server type" thread on mailinglist.
Export RTSPState and RTSPStream from rtsp.c into rtsp.h. This allows future access to these structures in functions that will be located in rtp_asf.c. See "[PATCH] RTSP-MS 2/15: export RTSPState and RTSPStream" mailinglist thread.
Don't use s->pb if a local ByteIOContext was already provided by the calling function. See mailinglist thread "[PATCH] RTSP-MS 1/15: don't use s->pb in asf.c".
Allow subscription to any of the streams, not just the first, available in this RTSP/RDT session. This basically implies full RDT support, including stream selection in ffmpeg and multi-stream backupping in ffmpeg (by mapping each stream to an output). See "[PATCH] RTSP/RDT: subscriptions" thread on mailinglist.
Parse the OpaqueData field for every AVStream represented by this "set of streams" (a single RTSPStream / RDTDemuxContext can represent several AVStreams, that's just how Real/RDT was designed...). This will fill in most of the AVStream/AVCodecContext header fields, similar to reading a RM file header would. See "[PATCH] multi-stream MDPR parsing" thread on mailinglist.
Parse the bitrate field in the ASMRuleBook ("AverageBandwidth") to fill in the AVStream->AVCodecContext->bit_rate field, which is not in the MDPR block (the "OpaqueData" SDP field). This allows clients to choose streams based on their bitrate, which is what most network-players base stream selection on.

Split RMContext into RMDemux/MuxContext and make them private in rmdec/enc.c. Reason for this is that there are no shared entries in the demuxer/muxer context, making it a mystery as to why it was shared between the two. See "[PATCH] clean rmdemux/muxcontext" patch on mailinglist.
Don't access RMContext directly in rdt.c. Rather, use the return value of ff_rm_parse_packet() to indicate whether more audio packets are available in the demuxer from the last RM frame, and save that in the RDT parsing context. See patch/discussion in "[PATCH] rdt.c: don't access RMContext" on ML.
Do not invade _t POSIX namespace.
Separate the packet fetching from the data reading, so that the data reading function is assured to parse at most one packet. This makes this function useful for ASF data packet parsing in a "push-mode" in addition to the current "pull-mode", and therefore allows for use of these functions in, for example, the RTSP demuxer (for MS-RTSP support). Tested to give identical output before and after for regular ASF playback, also see discussion in the ML thread "[PATCH] asf.c: move packet_time_start=0 statement". Testsuite also works after the patch, tested by Benoit Fouet.

Change function prototype of the sdp_parse_a_line in DynamicProtocolHandler. This function is called in rtsp.c for each a= line in the SDP of the Describe response after m= RTSP stream descriptors. The function prototype used to take an AVStream argument. For RDT, however, every RTSPStream represents a set of streams of identical content, and can thus represent multiple AVStreams. Therefore, it should not take an AVStream as argument. This patch modifies it to accept a AVFormatContext (of the RTSP/SDP demuxer) instead. See discussion in "[PATCH/RFC] change function prototype of parse_sdp_a_line" thread on ML.

Fix memleak caused by the fact that url_open_buf() allocates a context when calling, but url_close_buf() doesn't free it. The better solution is to not allocate it at all, init it with init_put_byte() and then not have to close it at all. In the case where we do need to hold it around for longer than within the function context, we allocate it with av_alloc_put_byte() and free it with av_free() instead.

Implement RDTDemuxContext, which contains RDT-specific data (similar to RTPDemuxContext for RTP) for these streams where the transport protocol is RDT (as served by Realmedia servers).
Make RTPDemuxContext opaque in rtsp.c, renaming it to tx_ctx (tx=transport) and making its type a void pointer. See discussion in "RDT/Realmedia patches #2" thread on ML.
Remove access into RTPDemuxContext in rtsp.c, which allows making it opaque (and thus preparing for the introduction of RDTDemuxContext) in a next patch. See discussion in "RDT/Realmedia patches #2" thread on ML.
Change function prototype of RTPDynamicPayloadHandler.parse_packet() to not use RTPDemuxContext, but rather take a pointer to the payload context directly. This allows using payload handlers regardless over the transport over which they were sent, and prepares for the introduction of a future RDTDemuxContext.

Implement a RTSPTransport field, which allows proper separation of server types and their non-standard extensions, and the data they serve. Practically, this patch allows Real servers to serve normal non-RDT (standard RTP) data. See discussion on ML in "Realmedia patch" thread.
Remove access to rdt_data struct in functions called outside of the DynamicProtocol* context. Doing so could lead to problems if we're accessing Real servers serving non-RDT data (or the other way around). Temporarily, this patch adds a _subscribe2() function which will soon be removed in one of the subsequent commits. OK'ed by Luca in "Realmedia patch" thread on ML.
Send improper UDP SETUP request, which is what Realmedia servers expect. See discussion on ML in "Realmedia patch" thread.
Rename RTSPProtocol to RTSPLowerTransport, so that its name properly tells us that it only describes the lower-level transport (TCP vs. UDP) and not the actual data layout (e.g. RDT vs. RTP). See discussion in "Realmedia patch" thread on ML.

Rename yuv2rgb variables to avoid name clashes with the ones used by bfin asm.
Switch regression tests to swscale. Plain C, x86-32 and -64 have been tested and should work, other archs that had asm optmizations in swscale likely will need some fixes to either fall back on C if SWS_BITEXACT is set or make the asm match C. This also disables the PAL8 test as neither swscale nor the old scaler really support PAL8 output, imgconvert supported a fixed 666 palette as output and swscale supports fixed 884 and 422.

Move av_set_pts_info() inside the mdpr_read_codecdata() call, so that it is shared between the RM demuxer and the RTSP/RDT parser; both use the same timebase. See discussion in "[PATCH] rmdec.c: move av_set_pts_info()" on ML.
Use chunk-size in function calling mdpr_read_codecdata() rather than in the function itself. This way, old-style (.ra4) RTSP/RDT OpaqueData chunks can be parsed using this function as well (they don't have the size bits). See discussion on ML in "[PATCH] rmdec.c - small read_mdpr_codecdata() API modification".

In-loop deblocking filter for VC-1 decoder
My commit at r14340 was not the right solution. For a monochromatic frame, there will be only one centroid and it will be impossible to find three distinct ones. It is better to just avoid shifting if there are not three different centroids.
Do declaration and initialization separately in elbg.c to workaround an ICC bug.
When picking a "high utility centroid" do not pick one that has no corresponding points. Not only it is the worst possible pick, but also the code was written without this case in mind.
The codebook generator algorithm involves picking three different codebook centroids ("high utility", "low utility" and "closest to the low utility one"). This change avoid the corner case of choosing two times the same centroid.

One-bit bitfields should probably be unsigned. Unfortunately, it is left up to the compiler on how one bit fields are treated. gcc treats one-bit bitfields as signed and allows for the -funsigned-field parameter. Other compilers (like Sun C) treat one-bit bitfields as unsigned no matter what. Patch by Erik Hovland erik hovland org

ff_fetch_timestamp() prototype
In mpeg1/2 timestamps are associated with the access unit which contains the first picture startcode that commences in the PES packet, instead of the first access unit that commences in the PES packet. Fix the parser to handle that properly. This was a very long standing bug ... The change to the seek regressions is because the mpeg ts muxer stores too many invalid and randomized timestamps which overflow the 4 entry buffer we use in the parser.
add pretty common .m2t as ts extension
fix continuity counter to start at 0
Make update_initial_durations() also work if a dts occured before a sequence header (that is a few known dts/pts but no known durations previously) cnnts1.mpg is one sample affected by this.
Do not set pts in update_initial_durations() if stream has b frames.

indent
Only store timestamps when there are timestamps.
Our MPEG-TS demuxer does not send complete PES packets but sends them piecewise, thus the end values cannot be used for associating timestamps.
Move new field to the end to avoid ABI breakage, I thought this struct is not used from the outside but after rethinking it of course has to be used if someone wants to use a parser without a lavf demuxer.
cosmetic
Allow matching timestamps to be removed by fetch_timestamp().
Add off argument so that fetch_timestamp can search for timestamps not associated with the first byte of access units.
Factorize fetch_timestamp() into its own function
unused variable

Compiling ffmpeg.c fails when when the .ffm demuxer is enabled, but the .ffm muxer is disabled. The cause is an incorrect #ifdef that assumes that the ffm_nopts symbol (global define in ffmenc) is present when either ffm muxer OR demuxer is enabled. patch by Peter Ross, pross xvid org

Ensure that one can store X bytes in a fifo of size X. Fixed issue417.
Make av_fifo*_read() ignore the available amount of data. This is more efficient as in practice the check is redundant most of the time. Callers which do not know if enough data is available have to check it with av_fifo_size(). Doing the check in *read() means the caller has no choice to skip the check when its known to be redundant. Also the return value was never documented in a public header so changing it should not break the API. Besides this fixes the case where read() failed on a 100% full fifo.
Make opt_verbose() work again.

Implement poll_frame() method. Fix ffmpeg.c bug with vf_fps filter.
Rework link property configuration system. This can now handle filters which are added to graphs out of order, including auto-inserted scale filters.  As an added bonus, it can now detect circular filter chains which wouldn't work anyway.
Use separate fake filters for exporting inputs and outputs from filter graphs. This makes the code a little less confusing, and is needed for the patch to improve the link configuration process, to be committed next.
Use a filter graph description for creating simple chain graphs so we can reuse the same graph creation code.

Fix issue357 Do what the spec says, insane or not: " Format 0 (uncompressed) and Format 3 (uncompressed little-endian) are similar. Both encode uncompressed audio samples. For 8-bit samples, the two formats are identical. For 16-bit samples, the two formats differ in byte ordering. In Format 0, 16-bit samples are encoded and decoded according to the native byte ordering of the platform on which the encoder and Flash Player, respectively, are running. In Format 3, 16-bit samples are always encoded in little-endian order (least significant byte first), and are byte-swapped if necessary in Flash Player before playback. Format 0 is clearly disadvantageous because it introduces a playback platform dependency. For 16-bit samples, Format 3 is highly preferable to Format 0 for SWF version 4 or later. "
flv/swf do not have a big endian codec id, they only support little endian and native endian.

AC-3 decoder, soc revision 53, Aug 17 08:53:44 2006 UTC by cloud9 Converted the window from double to float. Now sound produced is as good as sound produced by liba52.
AC-3 decoder, soc revision 52, Aug 16 22:45:07 2006 UTC by cloud9 Reset the blksw and dithflag to 0 at the begining of each block. Otherwise blockswitching propagates over multiple frames even if block switching is not enabled for that frame. Also reuse rematflg.
AC-3 decoder, soc revision 48, Aug 16 11:27:49 2006 UTC by cloud9 I realized that the bug was not in the imdct routine but in the get_transform_coeffs. Fixed it. Code now uses the ffmpeg's imdct routines. All the mplayer's ac3 samples are decoded successfully. Also improved downmixing. Now all the downmixing coeffcients for channels are normalized such that the sum of coefficients used to construct the output for single channel never exceeds 1.0.
AC-3 decoder, soc revision 40, Aug 9 00:10:14 2006 UTC by cloud9 More code cleanup. Window is now runtime generated. Fixed the bugs in rematrixing routine and in Decoding AC3 Bitstreams when coupling is in use.
AC-3 decoder, soc revision 38, Aug 7 00:03:00 2006 UTC by cloud9 major code cleanup. correct implementation of imdct. implemented imdct for block switching also. when coupling is not in use all the ac3 streams are decoded correctly. but when coupling is in use there is a bug. i am currently finding the root of the bug. if anybody can help.
AC-3 decoder, soc revision 34, Jul 18 14:27:54 2006 UTC by cloud9 working decoder imdct for block switching is to be implemented various other things to do
AC-3 decoder, soc revision 33, Jul 17 12:13:40 2006 UTC by cloud9 getting weired output but its working
AC-3 decoder, soc revision 32, Jul 17 09:37:32 2006 UTC by cloud9 Latest commit. There is no error in parsing and or recovering transform coefficients. Double checked with ac3dec. Getting consistent results with the bit allocation routine and transform coefficients. The code is able to parse valid ac3 bitstreams without error from start to end. I have also implemented the imdct when block switching is not enabled. However, can anybody provide an insight into how to convert float samples to int16_t ? lrint is of no help cuz it produces output -1, 0 or 1 whereas the output should be between -32768 to 32767.
AC-3 decoder, soc revision 31, Jul 14 23:53:28 2006 UTC by cloud9 Removed _ from names Removed temporary storage for the exponents Removed ctx->samples Now each transform coefficients are stored in audio block as an array of transform coefficients for each channel added ctx->delay (output of later half of previous block) added audio_block->block_output(output of this block)

When dst_length == 0 bit_length has to be 0, too, but the current code still calls decode_rbsp_trailing() and therefore bit_length might get negative. Although the remaining code is able to handle a negative bit_length, avoid the calculation at all by setting bit_length to 0 for dst_length == 0. patch by Reinhard Nissl, rnissl gmx de
Remove a NAL unit's trailing zero bytes even when dst_length is 1. Consider the following byte sequence
scenario: A properly coded frame is followed by an end of sequence NAL unit, i.e. the four bytes 00 00 01 0a. When decode_nal() decodes the end of sequence NAL unit, it returns with dst_length == 0. The original code leads to a return -1 which discards the current properly decoded frame. patch by Reinhard Nissl, rnissl gmx de

The NSV demuxer assumes that a video frame's timestamp increases by one on each frame, but some low-bitrate NSV files omit video frames for some NSV frames, and expect the timestamp to increase by one every NSV frame.

av_estimate_timings_from_pts() flushes the packet queue but doesn't reset the streams' cur_dts values.  This can lead to a fatal "error, non monotone timestamps ..." message later, because the out-of-date cur_dts values are used to compute some packet's dts.

libnut uses "MP3 " for mp3

zero private bits
store a identifer and the first header in extradata with this mp3 should be binary identical to what you had before header compression support mp3 with crc (by droping the crc and putting it back during header decompress, currently its just random tough, does any deocoder even check it?)
also set strict_std_compliance for stream copy, its needed for the bitstream filters
mp3 header (de)compression bitstream filter this will make mp3 frames 4 bytes smaller, it will not give you binary identical mp3 files, but it will give you mp3 files which decode to binary identical output this will only work in containers providing at least packet size, sample_rate and number of channels bugreports about mp3 files for which this fails are welcome and this is experimental (dont expect compatibility and dont even expect to be able to decompress what you compressed, hell dont even expect this to work without editing the source a little)

optimize sign decoding code in decode_residual() x86 is 4% faster on P3 C sign stuff + x86 code for everything else is also faster then before (sorry forgot to test pure C) ... and if i replace the second occurance of the sign decoding in decode_residual by the asm too then everything gets slower iam starting to think that it might be best to write the whole function in asm, playing this avoid random deoptimizations game with gcc is not fun at all

shift CABACContext.range right, this reduces the number of shifts needed in get_cabac() and is slightly faster on P3 (and should be much faster on P4 as the P4 except the more recent variants lacks an integer shifter and so  shifts have ~10 times longer latency then simple operations like adds)

The reader ignores the size of the ASF data object and keeps on reading even beyond it. Therefore if the ASF file includes an index object at its end, the reader will treat the index like data, but of course will fail since it thinks that the data is corrupted. When reading an asf file with an index object, ffmpeg will complain at the end of the file that it read an invalid header.

Try to find out correct start time to make seeking faster and add some extra checks to make sure the seeking function will not hang forever.
Missing part of the malloc -> av_malloc patch: memalign must be replaced as well!
Correct edge MC for chroma
disable libtheora, this change leaves all the libtheora related code in svn for now but just disables it in configure IMO libtheora support should be completely removed but at least under no circumstances must it disable or override our native decoder by default
Replace code for clipping MV vectors (which is wrong to use here) with clipping source coords.
Don't do non-uniform quantization on zero coeffs.
do not include bswap.h in common.h for external programs, since the former is not installed currently.

This patch simply adds demuxing support for AC-3 streams in DVB TS files.  In these streams AC-3 is given type 0x06 (private stream) and includes a descriptor with either tag 0x6A or 0x7A.  The code already handles ATSC AC-3 which uses stream type 0x81.  All the new patch does is look for any stream type 0x06 that has a descriptor with the proper tag (i.e. 0x6A or 0x7A) and if found forces it to be recognized as an AC-3 stream.

More spelling errors patch by (Kevin Baragona (kevinmb500 gawab com>)
While adding stereo rematrixing, I came across something that needs to be fixed even without adding the feature.  The output correctly uses 4 dummy values for the rematrixing flags in block-0, but the bit allocation routine does not take these bits into account.  From what I can tell, there was a patch in 2003 that corrected the output to make it DVD and spec compatible, but it didn't correct the bit allocation.  It's only 4 bits over the entire 6 blocks, so overflow errors would happen rarely or never, but it's still worth fixing.  So here is a fix.

increasing precission of the quantization parameter this is needed as the quantization stepsize for each subband is also in this precission and insignificant changes to the wavelet like scaling its coefficients slightly differently would lead to wildly variing PSNR and bitrate note, a encoder could also simply choose to leave the least significant bits of the quantization parameters zero which would give the exact previous behaviour except a y very tiny number of bits in  the header

- samples from mplayer ftp in the "adv" profile seem to have profile=2, which isn't the advanced one; and indeed, using adv. profile parser fails. Using normal parser works, and that's what is done - attempt at taking care of stride for NORM2 bitplane decoding - duplication of much code from msmpeg4.c; this code isn't yet used, but goes down as far as the block layer (mainly Transform Type stuff, the remains are wild editing without checking).

Fix synthetic next_pts calculation / audio pts patch by (Wolfram Gloger <wmglo at dent dot med dot uni-muenchen dot de>)
mpeg SVCD compatibility, SCR fixes, standard compliance - fixed VBR+constrained bitstream header flags for non-VCD - more sane (and SVCD compatible) value for video stream->max_buffer_size - always write at least one PES header stuffing byte for MPEG-2 to prevent accidental start code generation - do not write more than 16 stuffing bytes in a PES header (not allowed). Use padding packets instead. - include a PES extension in the first MPEG-2 packet - fill the first pack of SVCD files with padding - "sanity hack" that prevents the SCR from overtaking the PTS for non-VCD - fixed VCD PTS values to correspond to the SCR - always include DTS in the first SVCD packet (fixes lots of compatibility problems with DVD players)

    * moving some of the commonly used bit reading/writing functions       from common.c -> common.h so that they can be inlined.          + performace gain ~1% (measured with DV decoding) 	 + code bloat 0.05%       Looks like a win-win solution.

multithreaded/SMP motion estimation multithreaded/SMP encoding for MPEG1/MPEG2/MPEG4/H263 all pthread specific code is in pthread.c to try it, run configure --enable-pthreads and ffmpeg ... -threads <num> the internal thread API is a simple AVCodecContext.execute() callback which executes a given function pointer with different arguments and returns after finishing all, that way no mutexes or other thread-mess is needed outside pthread.c
ppc chroma mess workaround (real bug is that the motion compensation code assumes that 2*uvlinesize == linesize and fixing this would mean a slowdown)
   * turns out write_packet is supposed to return 0 on success, not      how many bytes were written.
    * gotta setup coded_frame for encoding. avcodec.h says that for decoding       lavc is supposed to set it up as well and I don't think I see any       reason not to.

2 byte shorter userdata for mpeg4 in the past it was startcode,string,00,7F,startcode now it is startcode,string,stratcode both are mpeg4 compliant, as according to the standard the userdata lasts until the next 00 00 01 (startcode prefix) but some very primitive decoders which simply skip until the first 00 byte and then expect the next valid startcode might fail with the old variant, just a theory though (didnt test if quicktime can decode it now)

caching of timestamps for mpeg-ps so seeking is faster move (av_)find_stream_index() to utils.c as its usefull outside mpeg.c assert checking enabled, to find bugs quicker, should obviously be disabled later (av_)add_index_entry() inserts new entries so that the list stays ordered and updates entries if already in it (av_)index_search_timestamp() cleanup (kill ugly goto) and shorter

This fixes the jerky video from vob files. However, I am convinced that this is the wrong solution to the problem. In particular, if you specify an output frame rate, then it doesn't work correctly. My feeling is that the pts value ought to be interpolated between those frames where the pts is actually known. Maybe someone else could do that (change the line that I added, setting a value equal to AV_NOPTS_VALUE). Happy Christmas.

Change abort() calls to av_abort() calls.
Change calls to abort() to be calls to av_abort()

dont trash mm0, its still used in the next iteration of the loop (fixes strange horizontal lines on some blocks in b frames on mmx only cpus)
same dc skip behavior for chroma & luma elimination, its confusing otherwise imho
skip blocks with small chroma dc too (if the user wants it) needed to avoid IDCT(input coeffs !=0) == 0 problems which cause catastrophic error accumulation at qp=1
remove unused varibles patch by (Eric Sesterhenn <SnakeByte at gmx dot de>)
patch by (Volker Moell <volker-ml at die-moells dot de>)   creating $(prefix)/bin and $(prefix)/lib   improved linking libavcodec.so -> libavcodec-$(VERSION).so   ldconfig does not rise an error on not beeing root when installing
* skiping unwanted packets when it's possible * using 64bits us timestamps (needs more checking)
* using statics
* resync without endless loop
faster vlc table selection
* added support for multiple payloads
* ok - let's start with avifile->ffmpeg morphing   for the begining it's major rewrite of asf parsing code   (tested only inside avifile at this moment)   it handles descrambling (though without WMA it's probably   useless inside ffmpeg... * extended AVStream structure to return information about   stream time length * extended AVStream to export  extra data found after standard   headers - not really usefull for ffmpeg - but Windows codecs   need them. * asf parsing is not yet finished but works nicely already   (at 100% better them before :))

MVI optimizations for motion estimation.
better big/little endian test
* Now we do not delete the feed file if it was created with the same   parameters as the currently desired codec settings. Thus it is   important not to fiddle with the streams if you want to keep the   old data. * Fix it so that the ?buffer= paramter can be larger than 40 minutes or   so. Why is this good? So I can use ?buffer=43200 and get video from   12 hours ago (i.e. when it is daylight outside)
* Removed a debug printf * Fix the sense of the test for "-" with customlog and not closing stdout in daemon mode
dump bits per frame / qp / frame complexity support
handle DRI/RST markers patch by Leon van Stuivenberg <leonvs at iae dot nl>
Add notes on the ?date= format.
Add conversions to and from RGBA32 and BGRA32.
Fix a potential endless loop (nb (1 * 3) / 2 == 1)
Add some examples of using ACL
* Make asf streaming work again. Now uses the output format asf_stream. * Add ip address based acls for streams. I recommend adding ACL entries   for all feeds to control who can submit stuff. You might also want to   consider who can get to your status page. * Make logging work again if customlog == "-"
Add conditional build of strptime
Add logic to figure out whether strptime is present on the system. If not, then get it built.
Add strptime into the source pool for those systems that don't have it.
* Add code for ffserver to get stream output formats: guess_stream_format * Add real parse_date code. This is much more robust and can handle localtime and UTC
Add prototype of guess_stream_format
Add another asf output format type -- asf_stream. The convention is that ffserver will always try and use the _stream suffix if possible.

Make dct_unquantize_h263 work on systems without MVI extension.
Update and activate dct_unquantize_h263_mvi. Thanks to Måns Rullgård for some improvements.
Use updated motion compensation routines.
Activate ALT_BITSTREAM_READER by default on Alpha, since it seems to be a noticeable win (at least for me :)
Assembly version of put_pixels. This is currently the function that takes the most time, and it allows for more efficient unaligned access and better control over memory latencies.
Add profiling support.
Implement put_pixels_clamped and add_pixels_clamped in Assembler. This allows better scheduling of the memory accesses, and is portable among all compilers.

4mv bugfix
10l
100l (non mmx versions didnt compile) some cleanup
IF09 is alias for YVU9 (actually it has extra 4th plane containing MC change flags, but it doesn't matter for now) - IF09 is supported by win32 Indeo codecs and by some others too
yvu9 support (other planar yuv formats with other chroma subsamplings should be trivial to add, if they had a IMGFMT) disabled broken (=new) converters (they cause random sig11) various bugfixes
cleanup
selftest support bugfixes
more mpeg4 fourcc's
cleanup & grayscale support
fixing wmv1 bugs, it was foolish to belive that m$ would use the same dc prediction as mpeg4 just cuz they changed it a bit from msmpeg4v3
sync with mplayer xp - partial yvu9 support (copy only) - rgb 15/16 -> 24/32 converters - int->unsigned changes
pre-yvu9toyv12 converter, only grayscale Y-plane coping :)

Change ticker_tick to use ticker_abs as we want the absolute number of ticks. In particular we want an INT64 return.
Add ticker_abs function that returns the number of ticks to get the supplied frame (or sample) number. This is not the same as ticker_tick
8bpp bugfixes (brightness, contrast ...) 4bpp
ordered dither for 8bpp
8bpp support (no dithering yet, use -vop noise for now)
Change the way that the ?date= stuff is parsed. It now takes a time (with optional date) in local time rather than GMT. Note that you are advised to use the date as well as the time as the time is relative to the current day (which is not much use if the time is in the future). The date format parsing is pretty strict still: YYYY-MM-DDTHH:MM:SS   is a format that works. The T is a literal non-digit character. I wouldn't use a space. The :SS can be omitted. The number of digits *must* be four in the Year.
reverted to inttypes.h since it gives problems on some unixes
moved code to mem.c and allcodecs.c
fixed one mpeg decoder memory leak
move unaligned access macros to dsputil.h - added unaligned 32 bit store
memory functions are exported
put codec registering in another file so that the user can install the codecs he wants
put memory functions in a separate file so that the user can redefinite them without modifying the library
added installlib target to install static libraries and includes
do not export internal functions - use stdint.h
optimized ticker_tick() if num is big - please test it (should reduce CPU usage - this code is temporary before new PTS handling scheme)
* Add code to restart ffmpeg if it crashes * Add code to monitor the actual datarates on the http connections * Fix problem when ffmpeg uses more than 24 hours of CPU (display only problem)
grayscale only encoding
passing avctx->flags so that grayscale only decoding works with mpeg1/2 too

* Get the buffer size right now we have the buffer inside the FFStream block
Add the copyright/comment/author/title keywords
* Add the comment block if any of the comment fields are present. * Eliminate compiler warning * Add the codec name if we have it
* Give the max stream time configuration item a chance of working * Add parameters to set author/comment/copyright/title to streamed asf * Format the stats output a little bit better.
Remove some calls to av_free that tured out to be duplicate. This improves the behaviour of ffserver streaming asf files from disk.
run1 can be <0 bugfix (found by fabrice)
avoid name clash with libjpeg - added missing externs

bugfix
mpegaudio decoder is in high precision mode by default (low precision is only interesting for slow/old CPUs)
fixed layer1/2 overflow if very loud sound - fixed broken free format decoding to pass all mpeg audio standard decoding tests (please avoid patching the parser without having all test streams available - contact me if necessary)
* Bad buffer management bug. Forgot to take care of the case   where doubling the size of the buffer is not enough.
* removed MANGLE from macros for setting constants * using MOVQ_WONE/MOVQ_BFE as two instruction instead of static memory value access   as its always faster * PAVGB_MMX macro is using now mm6 -> mm7 is unmodified * replaced original pixels_xy2_mmx with new faster and equal implementation * replaced usage of mm7 for other then ZERO contstant in _rnd & _avg file with mm6
Added Launch, FaviconURL and Redirect examples
* New stuff and bug fixes: * Change to dynamically allocated buffers. Should reduce memory footprint significantly   as well as eliminate a call to av_abort! * Better version of WMP rate switching infrastructure. Currently turned off till   the PTS fixes are in. * Added a Redirect type feature. This allows URLs served by ffserver to just   redirect to somewhere else. You might want to do this. Really this needs to   be enhanced -- say to handle all 404 pages. * Add mechanism to automatically fire up ffmpeg on ffserver start. This is turned   on by adding the Launch keyword to the <feed> definition. * Add logic to take care of non-wmp user agents requesting .asf files. They now get   a [reference] file with an appropriate mime type. This fixes the mplayer problem. * Make sure that we have a large buffer for the stats page. * Add a FaviconURL keyword to the status stream definition. If set, then it   generates the appropriate HTML so that IE and Mozilla will display the favicon   as appropriate. OK -- this is a pretty random feature. * If the ffmpeg is running as a child of ffserver, then report it's CPU usage   on the status page. [This is linux only -- maybe somebody could do the work for   another OS. The tricky thing is getting the 'ps' command right.]
* Go faster stripes: don't check to see if the user presses 'q' if stdin   returns EOF -- e.g. it is connected to /dev/null * Make the 1MB video buffer only allocated once rather than on each frame.   The allocation and deallocation causes significant performance loss as the   kernel remaps the address space each time.
Make sure that the http_proxy environment variable starts with http:// If not, then ignore it's value.
* added dependency on dsputil_mmx_rnd.h for dsputil test
* using unrolled loops seems to help to MMX Celerons * calculating average in parallel to use two MMX units * disabled xy2 put code - it's producing rouding errors
* reenabled original xy2 put routine - rounding error is really bad with   the new code * added PAVGP macros for parallel processing to safe few more cycles on   celerons
* code with new PAVGB for MMX only CPU splited into separate file   and being compiled in the same way as _avg.h * PAVG_MMX macros accept also output parameter * implemented faster put_pixels_xy2, but it has slightly smaller precission.   But there is not visible difference in the image quality - might be eventualy   easily switched back (#if 0 #endif)- please check
* new mmx code - based upon http://aggregate.org/MAGIC   for now it's rather sneak preview (new functions are nearly 100% faster)
* cosmetic minor change
* optimized remaing avg_pixels_xy2
* Make video grabbing work again (if you are grabbing multiple streams   at different frame rates). * Do the av_abort() change that is not otherwise worth checking in.
* optimized avg_* functions (except xy2) * minor speedup for put_pixels_x2 & cleanup
fixing stackoverflow
* started to cleanup name clashes for onetime compilation
* more PIC friendly and faster code
* removed TESTCPU_MAIN - not needed for testing
* for this moment  bswap.h included ahead of HAVE_AV_CONFIG_H check   as its functionality is used even in those parts which are being   compiled without this flag   - generaly this would require more complicated cleanup patch   - for now leaving for the main author
* yet a bit more extended * fixed busy loop test bug on mmx-only machine
* undefine local defines when they are no longer needed
* added
* compatibilized declaration with its original definition   (though I'm not sure which one is correct - but they should match)
* avoids double inclusion of this header   (how about making all headers in ffmpeg working this way ?)
don't use inttypes.h - use inline function for bswap_64()
use sys/soundcard.h for OSS audio
bsd fixes
fixed mangle issue
removed invalid buffer handling
untested generic bswap64
* Add first cut of code to handle Windows Media Player rate switching   requests. The current state is that at startup, WMP will get the   best stream that it can handle. However, subsequent rate switching   only puts a message in the log saying what the new stream ought to   be. Solving this will be tricky. I guess that we would have to wait for   key frames to appear in the new stream, and then switch over to it.   Some care would be needed to deal with the PTS of the new stream   versus the old stream.

Change order of extensions and read_probe checking. This gives the read_probe a higher priority than extensions. This gives FFM a chance of working. Note that some of the other probe functions are bit optimistic, and can be confused by binary data (such as 0x00 0x00 0x01 0xzz) for some values of zz.
* Add a probe function for FFM files
* Added yet more output to the status page to try and track down a problem
* Fix a problem caused by a duplicate free of priv_data -- now uses av_freep * Make sure that the read buffer for the ffm file is allocated in the priv_data.
* Add support for time-limiting a live stream. (Some guy streamed one of   my pondcam streams for 24 hours! I'll bet he wasn't watching. * Add code to allocate the priv_data so that the ffm header can be   parsed again. [Fix crash]
Add an av_abort macro that aborts, but also prints out the location of the abort. Helps track down bugs.
* baling 8  seems to have the same speed
* cosmetic
* always baling even though it seems to produce sometime worse   results then for -fPIC compilation - don't ask me why...
* cleanup for put_pixels_mmx
* minor update
applied 64bit patch from Ulrich Hecht <uli at suse dot de>
* a little bit extended dsptest also suports dsptestpic target
* somewhat more advanced test suit for dsp code - for now i386 only   cd test ; make dsptest ; ./dsptest
* align the source initialy address
* fixed contrains and avoid usage of scale index access
* added simple test main - see comments about how to   compile - should be probably made as a regression test
using 1 operand less and slightly faster put_pixels_y2
* fix for -fPIC compilation - compiles with 2.95.2 as well - any   other compiler shows any problem here ??
* minor cleanup
workaround dc_scale bug in old ffmpeg msmpeg4v3 encoder (set workaround_bugs=1 for this)
* oops - these are the midnight commits...   removed -fPIC used for testing compilability
* restored previous behaviour for this moment   users are supposed to supply proper SCR_PATH however
* restored previous non '..' version
fixed incorrect global gain - slightly increased precision of n^(4/3) table
* using ../ for bswap.h
* avoid conflicts with non-ffmpeg config.h and also it's consistent   with few other header files included from the main ffmpeg's dir

* If a stream gets stuck in WAIT_FEED, then disconnecting the other end   will clear out the stream. I think that this is really a linux bug in   the handling of poll, but I did a workaround anyway. * Improve the statistics output and prevent a buffer overrun when lots   of clients are connected. * Process ffm input when it is received and don't always be one ffm   packet behind. * Try to avoid going through the poll loop when not required.
Fix the WAIT_FEED problem. It turns out that when you open up an FFM file and seek to an FFM packet, then it is important that the packet found has a frame header within it. If not, then terrible things happen. This fixes the problem.
updated for my short term goals
qmin==1 bugfix
shared lib support (req by kabi) ...
* Added a note that says that WMP cannot stream .mpg files.
Added use of StartSendOnKey
* Change the default behaviour to start streaming as soon as possible (i.e.   no waiting for key frames). * Provide StartSendOnKey paramter for a stream to wait until we get key frames   before sending. * Add the codec names into the status page. May help debugging problems.
hopefully faster mmx2&3dnow MC
new hopefully faster MC
print frame decoding time support (x86 only)
* fixed --enable-shared handling
* Updated with new stream configuration items
* Add code to configure the following:   * prebuffering/preroll a live stream -- this improves startup time   * videoqmin/videoqmax/videoqdiff -- codec parameters   * maximum bandwidth for live streams * Add support for .ram and .rpm extensions mapping onto .rm * Make the status page show bandwidth. Also make the .asf and .rm   links go to .asx and .ram files. * Make a stream only start streaming when it gets a keyframe on each   stream. This is arguable, and it maybe ought to be restricted to   live streams. However, since I don't think that file streams work,   this is a step in the right direction. It improves the startup delay. * Log an error if we are unable to delete the temp feed file.
Pass over the bit_rate_tolerance field to ffmpeg
fixing end overwrite bugs (some at least) this needs testing, untested parts should be reversed before release i tested 24->32, 15->16, bgr24->rgb, bgr32->rgb (retesting them isnt a bad idea either ...)
- Bug fix for AVStream->r_frame_rate not being initialized for live video capture.
- Now ffmpeg handles MPEG-2 streams with pull down, it gets the real frame rate of the stream.
- Added r_frame_rate in AVStream to store the real frame rate. - This stuff could be done in AVCodecContext and the real frame rate calculated in utils.c, but we don't changes in that by now ;)
- repeat_pict meaning changed, now it signals the extra delay for the decoded frame. - extra_delay = (repeat_pict / 2) * (1/fps)
enable simple-idct by default (needed cuz otherwise files encoded with ffmpeg will show stripes with the reference IDCT during decoding)
* first shot for the new avcodec API   - comments, critics, improvements on the ffmpeg list are welcomed
* Mea culpa: it seems that I broke encoding to 8-bit pcm files. This fixes it.
- Video CD option for ffmpeg
- VCD MPEG-1 compliant stream support (set AVF_FLAG_VCD)
build num ++
build info for ABI
I was too lazy to be a hero ;)
- ffmpeg relies on libavcodec to repeat frames from 3:2 sources.
- repeat_pict added to AVCodecContext to signal if the decoder must repeat   frames from 3:2 pulldown sources. - repeat_pict honoured by MPEG-1/2 decoder.
various openbsd and general warning fixes - patch by Björn Sandell <biorn at dce.chalmers.se>
- Fixes for MPEG-PS which have more than 1 system header, now we don't take   in account the system header just walk through the file searching streams.   MPEG-PS demuxer needs more work anyway.
- pict_type exported to AVCodecContext - Added real_pict_num to AVCodecContext, it represent the number of the   previous encoded frame, usefull when coding with B frames. - Warning fix in motion_est.c
- Bug fix in map stream parser
* Improve logging -- now actually gives you the number of bytes sent * Print out the logging information that comes from WMP (you'd be suprised what   it sends! * Fix a remotely exploitable buffer overflow (argh!) * Add support for automatically serving up .asx files. It generates an automatic   redirect to the associated .asf file (with the same parameters). I guess that   someone who understands the realaudio equivalent could hack that it as well.
* Add implementation of strlcpy * Fix endless loop in find_info_tag if given specific arguments
* Add prototype for strlcpy
* Add the 'flags' field to the list of codec fields passed from ffserver to   ffmpeg. This gives the VideoHighQuality patch a fighting chance.
- HQ option for ffserver. Thanks to D Richard Felker III.
version info for so too
- Warning fix.
- Updating docs....
- Changed default qmin = 3 as ffmpeg.c - Less bitrate tolerance since we are streaming.
- Segfault fixed when mpeg audio decoder returns a negative data_size.
* Don't allocate 0 bytes of memory. It upsets electricFence!
* Fix a problem with the first sample when down sampling. * Note that this code needs to be fixed -- the rate conversion from 48000->44100   sounds horrible!
* Every frame is a key_frame
* Start using enumerated types (makes debugging much easier)
* Make put_wav_header return the number of bytes that it put.
* Change extern inline to static inline so that it will compile without optimization
* Try and fill out some more of the RV header fields correctly
* Add defaults to switch statements
* Add a sleep when doing the post to ffserver. Yes, this is the wrong   solution.
Intialize the codec type to video.
* Add the gop_size to the video parameters. Also the audio framesize. * Copy the duration over as well, though I'm not 100% certain that that is   still needed.
* Change extern inline to static inline. This improves compiling without optimization.
* Add default cases to switch statements.
* Add a duration field to the AVPacket
* Make it work with sound cards (like mine) that can only capture in stereo. * Add a kludge to allow the left channel to be inverted -- my tv card/sound card   ends up with the left channel = minus right channel. Converting to mono by   adding the channels doesn't work well.
* Many, many changes to make it work (mostly). Information snagged from   staring at headers of real ASF files. ASFRecorder and avifile were   other useful sources.
* Updated so that some streams actually work!
* These are my notes on streaming
* Fix a nasty problem with output buffering not have enough (or large enough)   buffers. In fact, the code was pretty much shot. * Try to fool WMP into thinking that we are a microsoft server. * When we establish a stream to a user, copy the codec information from   that saved as part of the stream. This gives us the real frame_size and   other important parameters. * ASF needs to know about key frames, so add some logic to copy this information   around. * When we get the data from ffmpeg as part of a feed, make sure that we save   the actual codec parameters. * Allow configuration of AudioCodec and VideoCodec * Make sure that we delete the feed file before starting. This is not ideal   but it makes things work a whole lot better!
* Fix nasty problem with unitialized memory in the file_table * Add default entries to switch statements to catch programming errors * Fix problem with high CPU usage when capturing live (the audio grabber   is non-blocking for some reason). This is the stream_no_data stuff. * Handle the video grabber getting behind in its work -- PKT_FLAG_DROPPED_FRAME
Move the EXTRALIBS to the end of the link line where they actually get used!

- New switch to activate 4MV in ffmpeg.
- Fixed AC3 decoding for 5:1 AC3 streams. Now when calling av_audio_decode for AC3 set avcodec_context->channels to the desired number channels, if the setting is 0 AC3 decoder will set it to the channels found in the stream. - Changed ffmpeg to cope with the new "way" of AC3 decoding. - ASF muxer now uses Tickers for PTS calculations.
- PIX_FMT_ANY = -1 to avoid breaking any stuff that could be using it. Thanks to D Richard Felker III for his comments.
- Commented out PIX_FMT_ANY by now. It seems that not all codecs are setting the PIX_FMT_ so they get PIX_FMT_ANY instead of PIX_FMT_YUV420P which obviuosly annoys ffmpeg.

* simplified indexing * ignoring error from msmpeg4_decode_block
* simplified indexing
* eliminating duplicated code from MPV_common_end * simplified indexing
* using static instead of extern
* continue after error in msmpeg4_decode_mb - helps for some movie samples
avoid overflow of picturenumber*fps*10000 bug found by Lennert Buytenhek <buytenh at gnu.org>
block_last_index was too large (in mpeg1 decoding)
- Minor changes on bitrate control
optimized the normal bitstream writer, its faster than the alternative one on p3 now ... lets hope its at least not slower on p4 & k7
minor dststride bugfix for i420 output srcHeight %2 != 0 bugfix / chroma height = (luma height +1)>>1 in YV12
optimized encode_dc() (+2% speed on P3 for mpeg1 intra only encodings)
optimize mpeg1_encode_block() (makeing some constant arrays global, merging put_bits(), ...)
aligned bitstream writer (1% slower on p3 but perhaps its faster on p4?)
alternative bitstream writer (disabled by default, uncomment #define ALT_BISTREAM_WRITER in common.h if u want to try it)
unscaled memcpy variant bugfix (negative strides)
- More work on preliminary bit rate control, just to be able to get an average variance for picture's MBs so we can adjust qscale on the MB layer.
- Now the ME is done for the entire picture when enconding, the DCT/Quantization is done after we have calculated all the MV of the picture. - This is the preamble for a better bit rate control.
unscaled BGR24 -> YV12
