However, after a seek the parsed packet still contains a partial frame before the next full one. I had expected libavformat/mpegaudio_parser.c to detect this situation and discard the fragment, but unfortunately it does not. Instead it passes it unchanged to the codec, which plays it as a pop or even a very ugly BLEEEP - painful while wearing headphones! I assume this situation never arose with other (more sane) format demuxers… So, should I rather try to patch mpegaudio_parser? Seems risky? > [...] > -- > Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB > > I have never wished to cater to the crowd; for what I know they do not > approve, and what they approve I do not know. -- Epicurus > > _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
