Comment:
Yeah, it is indeed a bug. If you will then '''-c copy''' that broken mkv
to mp4 it will show:
{{{
Frame rate mode : Variable
Frame rate : 24.000 FPS
Minimum frame rate : 23.634 FPS
Maximum frame rate : 24.390 FPS
}}}
that '''IS''' wrong and does not happen with nut convert to mp4 '''-c
copy''' to mkv '''-c copy''' to mp4 and happens because (as ffmpeg warns
on mp4 '''-c copy''' to mkv ):
{{{
[mp4 @ 0000014f82a864c0] track 1: codec frame size is not set
}}}
