I compiled new ffmpeg I tried to cut mp4

-to parameter was coming from mpv:

bash-5.1$ mpv ~/6029.mp4
 (+) Video --vid=1 (*) (h264 720x400 25.000fps)
 (+) Audio --aid=1 (*) (aac 2ch 48000Hz)
AO: [alsa] 48000Hz stereo 2ch float
VO: [gpu] 720x400 yuv420p
(Paused) AV: 00:01:04.600 / 01:28:31.600 (1%) A-V:  0.000

1 min + 4 seconds +0.600 milliseconds = 64.600 ?

bash-5.1$ /dev/shm/ffmpeg/ffmpeg -i ~/6029.mp4  -copyts -c:v copy -c:a
copy -ss 0.0 -to 64.600 /dev/shm/6029_cut.mp4

=====

MB4Box from gpac 1.01. compiled without ffmpeg support.

but even ffprobe says:

Duration: 00:01:04.68 - so we have 80 milliseconds of difference from target?

MB4Box seems to say:
Computed Duration 00:01:04.800 - Indicated Duration 00:01:04.800
but for audio track
Media Duration 00:01:04.618 - Indicated Duration 00:01:04.618
Track has 1 edit lists: track duration is 00:01:04.619

so, they all a bit differ ....
