FFmpeg API users are not supposed to use fourcc fields to identify codecs. The fourcc variable in matroskadec.c is copied to AVCodecContext.codec_tag, which is not necessarily a fourcc (depends on the CODEC_ID; most time it's unused), and the svq3 decoder in libavcodec doesn't read it. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
