FFMPEG extract frame-accurate video fragments with minimal transcoding
9 mars 2018, par LeeroyHow can I extract frame-accurate video or audio fragments using FFMPEG without transcoding the full portion ?
ffmpeg -i input.mp4 -ss 00:00:01.234 -to 00:00:05.678 output.mp4
works because it re-encodes... If I use-codec: copy
then it disregards the precision of my start and end time arguments and instead uses the closest keyframe (I understand).Is there a command or combination of commands to instruct FFMPEG to transcode only what’s needed, the bits near the start/end markers, up to keyframes ?
EDIT : A bit of context... I’m trying to write this function to process video piped from
youtube-dl
, perhaps even as a service. So it matters that I minimize bandwidth (downloading to timestamp and discarding after) and CPU utilization (re-encoding all of the fragment). -
