Here is a new version of the patch. Support for paletted video formats
should be back (as far as I can tell from gst-libav1.0's code
*_set_palette was removed altogether and is no longer needed). Support
for planar audio formats gives me headaches as too much has been
changed. I've started to backport it for the encoder but failed to do
so for the decoder.

In gst-libav1.0 gst_ffmpegauddec_get_buffer gets a GstAudioInfo pointer
from a GstAudioDecoder* instance. Where do I get that from in
gstreamer-ffmpeg0.10? Or is there some other way to get the same
information? The same questions also bugs me for the encoder.

Since GstFFmpegDec is not a GstAudioDecoder, what's the proper
replacement for gst_audio_decoder_allocate_output_buffer? (as used in
gst-libav1.0's gst_ffmpegauddec_get_buffer)

Any help would be very appreciated.

Regards
