#7137: bitstream filter dump_extra does not work with -vcodec copy -----------------------------------+----------------------------------- Reporter: leeoxiang | Owner: Type: defect | Status: new Priority: normal | Component: avcodec Version: 3.4 | Resolution: Keywords: h264 | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+-----------------------------------
Comment (by mkver): The H.264 track in your input file isn't in annex B format, but in mp4 format. So are the extradata. The thing is that the format of the mp4-style extradata is different from the format that is used at the mp4 sample level; in other words, the output of the dump_extra bitstream filter is a totally invalid stream. Use the h264_mp4toannexb bitstream filter before dump_extra. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7137#comment:2> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://ffmpeg.org/mailman/listinfo/ffmpeg-trac
