[FFmpeg-user] Cutting a mp4 with a second precision

[Julien Roch]

Hi List,

I was wondering if it was possible to cut a mp4 video (h264/aac) with ffmpeg using the timecode inside the video and having a second precision (and not gop) without reencoding

For exemple, if the key frame is at 0h20m00s00f and that i want to cut at 00:20:00:12 . Ffmpeg would use the first keyframe to really start at the 12th frame and not at the keyframe

I know some systems can do that but i wonder if ffmpeg would be able to do that ?

Cheers,

Julien
