#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 jsd): brama: here is the workaround i devised: start with $vsync = 0[[BR]] if input file is wmv, set $vsync to 1[[BR]] encode as normal, with -vsync $vsync. if you get a "non monotonic timestamp" error, change vsync to 1 (if it wasn't 1 already, add -r 15 to the command line, then run the command again. with this algorithm, i have been able to successfully process just about everything that the internet has thrown at me. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/187#comment:6> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
