Comment (by forthrin):

 23.98 is the frame rate of the original file I am converting. I thought
 video_track_timescale took the input frame rate as argument? It works for
 me. Just too bad the value must be changed all the time.

 #5882 seems to have a good suggestion: "ffmpeg should guess FPS ... and
 write "video_track_timescale" automatically, even if the input is bugged
 ... check for input "timebase" and fix it on the fly."

 If for some reason it is not possible to fix FFmpeg this way, or the
 developers simply have no time or interest in solving the issue, just
 state this plainly, and I will pursue the issue no further.

 Unfortunately I am unable to participate on the mailing list, but if a
 solution actually exists for the current version of FFmpeg, it would be
 very kind if you could write it here, and in the "Compatibility" section
 of the official documentation:
 https://trac.ffmpeg.org/wiki/Encode/H.264#AdditionalInformationTips. This
 would be helpful to everyone who is converting video content to watch on
 Apple devices.
