#9210: Concat images produces wrong timings when duration is in milliseconds -------------------------------------+------------------------------------- Reporter: demet64 | Owner: (none) Type: defect | Status: new Priority: normal | Component: | undetermined Version: unspecified | Resolution: Keywords: concat | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Comment (by Nicolas George): Replying to [comment:7 Andre LaBranche]:
The unwanted 25 fps does seem to be coming from `concat`. I tested that along with `image2` and found that `image2` honors the frame rate passed as a cli option.
image2 honors the `frame_rate` option, but you never gave that option to the `image2` instances below the concat demuxer. I would not oppose a patch to concat to add a `time_base` option. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9210#comment:8> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
