You cannot reproduce because the movie attached is too short to seek. Is that a way(e.g. email or others) i can upload the whole movie(about 20M) to you. I can only upload attachment less than 2.5M here. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9863#comment:4> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

Same happens on a blu-ray I have of "Whiteout".
I did mention it here: https://trac.ffmpeg.org/ticket/8515#comment:3 Yes, I saw many keyframe flags. The decode-function may be affected if the player find the wrong keyframe after seek? -- Ticket URL: <https://trac.ffmpeg.org/ticket/9863#comment:10> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
