Comment:
>But I have a similar problem in VLC pausing, seeking to 0, then pressing
E for next frame, I am still at TC 00:00:00:00.
VLC is buggy as hell. It is not at all surprising, VLC does not even have
step backward. mpv works correctly (it has . and , buttons to step forward
and backward) and so does MPC-HC (Ctrl-Left, Ctrl-right).
As for output25.mp4 it works correctly: ffmpeg.exe -ss 00:00:00.01 -i
C:\Users\ZAQU\Downloads\output25.mp4 -frames:v 1 out-b.png
as for chrome it switches between 0.040 (1/25 is 0.04000) and 0.040001, so
you need to find out why is that, but 1/25 is not actual number used in
Chrome. (1/25).toFixed(69)
'0.040000000000000000832667268468867405317723751068115234375000000000000'
