#333: Badly interleaved AVI file not handled -----------------------------+-------------------------- Reporter: ubitux | Type: defect Status: new | Priority: normal Component: avformat | Version: unspecified Keywords: avi,interleaved | Blocked By: Blocking: | Reproduced: 0 Analyzed: 0 | -----------------------------+-------------------------- The broken file is available at streams.videolan.org/issues/ffmpeg/yet- another-broken-interleaved-avi.avi. The file seems correctly interleaved, but around 01:08, only video packets seems to be decoded. While MPlayer AVI demuxer is able to handle it ("Badly interleaved AVI file detected - switching to -ni mode..."), FFmpeg AVI demuxer doesn't. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/333> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

This problem does not occur with mpeg2 in same setup. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/393> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
