#187: 3GP/MP4 performance regression -------------------------------------+------------------------------------- Reporter: jsd | Owner: Type: defect | Status: open Priority: normal | Component: Version: unspecified | undetermined Keywords: | Resolution: Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Comment (by brama): Thanks jsd, that's very helpful. Did you also try to just revert the one change, and did that turn up any issues? I have run our entire test video set against ffmpeg-0.8.3 with the one commit reverted, and no issues with a/v sync have turned up at all. I'm also seeing problems with some mp4 input files, not just wmv. For those, the ffmpeg output contains: {{{ [mp4 @ 0xa590c20] Frame rate very high for a muxer not effciciently supporting it. Please consider specifiying a lower framerate, a different muxer or -vsync 2 }}} If going the vsync/fixed rate route, I'll have to rework our transcoder flow a bit to catch ffmpeg's output as it's processing (or have it transcode only a few frames and/or kill it after a number of seconds) to catch the output and rework the logic based on that. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/187#comment:7> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
