[FFmpeg-devel] FFmpeg command to trim lavfi ignores start

[FFmpeg-devel] FFmpeg command to trim lavfi ignores start

[Aziz Berkay Yesilyurt]

Hi there,

I have a simple command to generate a video clip using lavfi and trim it
using the trim filter.

ffmpeg -f lavfi -i color=blue@1:640x480:d=60,format=rgba
-filter_complex "[0]trim=start=4.0:end=5.0[s0]" -map "[s0]" -y
trim.mp4


I expect that the output video should be 1 second long, since the
start is 4 and the end is 5, but it is 5 seconds.

Modifying the end parameter changes the duration, but modifying the
start parameter has no effect.


Could someone explain to me what is going on?


Thanks,

Aziz
