Replying to [comment:6 RCJetPilot]:
> What is broken about the file? The file is captured by FFMPEG from a UDP
stream to a .ts file
Your file is VFR. You can check it with
ffmpeg -i VariableFrameRate.ts -vf vfrdet -an -f null -
It prints
{{{
[Parsed_vfrdet_0 @ 000002cef4b64a40] VFR:0.997207 (357/1) min: 1501 max:
3003 avg: 1505
}}}
VFR value is not 0, so it is VFR.
If you do -c copy to mp4 it will print the way it is. mkv conversion is
broken because there are no DTS in mkv, only PTS. See #7927.
