chromium doesn't link against the ffmpeg libraries, it dlopen() them, so
you are right for libavcodec52 libavformat52, but for libavutil50
it searches /usr/lib/chromium-browser/libavutil.so.50 , and this is a
symlink to /usr/lib/libavutil.so.50 .
If it doesn't find it you have the "Aw, Snap!" message or the "Sorry,
your browser does not support the <video> element." message.
In a standard Debian system, and with standard I mean a system with no
other third repositories, simply it doesn't use that lib.

At this point I removed that patch and made a new one that affects only
libavutil50 (not yet available in the archive):

-#include <libavutil/avutil.h>
-#include <libavutil/log.h>
+#include "patched-ffmpeg-mt/libavutil/avutil.h"
+#include "patched-ffmpeg-mt/libavutil/log.h"



So if I'm not wrong now there isn't any ABI incompatibility here because
libavutil50 doesn't exist as official package.
Is this acceptable?


Cheers
Giuseppe
