#3499: Error transcoding AVID H264 mxf file with seek (-ss) option -------------------------------------+------------------------------------- Reporter: chq.contact | Owner: Type: defect | Status: open Priority: important | Component: avformat Version: git-master | Resolution: Keywords: mxf h264 | Blocked By: regression | Reproduced by developer: 1 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Comment (by cehoyos): Replying to [comment:6 michael]: > I think the code should only be run when its needed, that is for codec tags that are affected, which in mxf i would hope is reliable. Unfortunately not: The sample from ticket #1294 that needs the extradata insertion, the sample from ticket #4820 that breaks remuxing (for QT) with the extradata inserted and the sample for this ticket all use the same codec_ul ("H.264/MPEG-4 AVC Intra") for the 14 bytes we check, the last two bytes are different for all three samples. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3499#comment:7> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
