#7799(avcodec:new): hevc_mp4toannexb filter inserts extradata wrong position
#7799: hevc_mp4toannexb filter inserts extradata wrong position ---------------------------------+--------------------------------------- Reporter: gudbooy | Type: defect Status: new | Priority: normal Component: avcodec | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ---------------------------------+--------------------------------------- Summary of the bug: After applied hevc_mp4toannexb filter to the attached video (refer to the below link), the frames become broken from the video players (e.g. VLC, ffplay) The problem is caused by prepending the extra-data to IRAP frames in libavcodec/hevc_mp4toannexb_bsf.c. This video contains own vps/sps/pps for every IRAP frames. The extradata from hevcc is slightly different from every IRAP frames have (in this case QP value is different) and the hevc_mp4toannexb filter prepends the different extradata to every IRAP frames, causing the broken frames. Video File Repo : https://www.dropbox.com/s/tpyohk6vf096zxm/hevc_after_mp4toannexb_conversion_... I am afraid that I can't connect to ftp://upload.ffmpeg.org, so I just attached to the dropbox url How to reproduce: {{{ % ffmpeg -i hevc_after_mp4toannexb_conversion_qp_value_modified.mp4 -codec copy -bsf:v hevc_mp4toannexb output.hevc $vlc output.hevc }}} Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7799> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

How did you create the input file?
Unfortunately, I did not create the video. It is automatically transcoded via a messenger application. (I do not exactly know how they transcode) I know how to avoid this issue, (just not prepend the extra-data, if the extra-data has already existed on IRAP frames) However, I do not exactly know whether this solution is correct or not. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7799#comment:2> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

One difference is that hevc_metadata currently only keeps the base layers (nuh_layer_id == 0), whereas hevc_mp4toannexb copies everything (before my
Please note that there is workaround with hevc_metadata, that is not affected, but in 2019 at least it could not "-c copy" nuh_layer_id != 0 patch). hevc_metadata will have a slightly higher complexity as it parses the full parameter sets. I will just point out how to test this bug on latest master: Bad: {{{ ffmpeg.exe -i hevc_after_mp4toannexb_conversion_qp_value_modified.mp4 -c copy ajcwsaq.h265 ffplay.exe ajcwsaq.h265 }}} Good: {{{ ffmpeg.exe -i hevc_after_mp4toannexb_conversion_qp_value_modified.mp4 -bsf:v hevc_metadata -c copy ajcwsaq1.h265 ffplay ajcwsaq1.h265 }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/7799#comment:18> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
