How to make ffmpeg remux an iPhone MOV (HEVC) that works on Apple products ?
21 janvier 2024, par Mikael FinstadI want to remux a HEVC file (without encoding). I have tried most options, even removing audio, but I cannot get an output file that plays smoothly with Apple products.



First I AirDrop any MOV from an iPhone recorded with the camera in HEVC.



Then run :



ffmpeg -i IMG_4605.MOV -c copy out.mov




Then if I send
out.mov
back to the iPhone and try to play it back, it plays back with glitches while seeking, like this : (original to the right)





When I try to drag the file into a new iMovie project and try to play it back, it freezes the whole iMovie app and needs a force quit.



Doing the same with the original causes no issues, so obviously there is something wrong with the way ffmpeg remuxes it, or something wrong with Apple's software.

If I open
out.mov
in QuickTime and do a trim and export it, then it it still "broken", so I'm thinking there's nothing wrong with the actual muxing into MOV, because QuickTime is passing the error on.


I noticed that
out.mov
has different parameters19200 tbn, 19200 tbc
(vs original600 tbn, 600 tbc
). However, if I force set these to 600 with-video_track_timescale 600
the output file is still broken.


Anyone got some insights ?
