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 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
