I'm fairly new to ffmpeg development, but there appears to be a parser
for vc-1 in libavcodec/vc1_parser.c, specifically an AVCodecParser is
defined starting on line 111. If that isn't what is needed, could you
point me to some documentation or maybe give me a quick overview of how
the parsers work to help me jump in and write a patch?

Don't you think it would be a good idea to hold off on changes that
break current files until the various codecs and parsers have been
updated to make sure they work with those changes?

Take care,
