#9412: HEVC fails to seek on keyframe -------------------------------------+------------------------------------- Reporter: SuRGeoNix | Owner: (none) Type: defect | Status: open Priority: important | Component: avformat Version: git-master | Resolution: Keywords: mpegts hevc | Blocked By: seek | Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Comment (by SuRGeoNix): Found another issue with HEVC (at least with the same LG Chess 4K Demo.ts) that might be related to this one. I have implemented a reverse playback by decoding from keyframe until the next one and then seeking to the previous keyframe (Manually ensuring that I actually have keyframe to keyframe). While decoding I'm draining the decoder properly but it seems that sometimes it misses some frames and I have at least 2-3 frames diff between the last draining frame and the next keyframe. I will do further testing and open a new issue if required. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9412#comment:3> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
