Hello,
i'm trying to cut an Adobe postprocessed F4v video (h.264 + mp3) with this
command :
ffmpeg -ss 00:10:00 -t 10 -i c:\video.f4v -vcodec copy -acodec copy -f flv
-async 1 videoout.f4v
but the output file duration is inaccurate;in my case 12 second and not 10
second .
If i try to insert an odd number in -ss (for example -ss 00:10:00) i have
this issue while an even number the duration is correct.
Can you help me to resolve this issue ?
Is the command above right?
I tried to download last ffmpeg version and compile one version too but
with the same results,
Thanks a lot in advance
Best regards
