comment How do I get the number of frames in a video on the linux command line?
That's pretty good. In my experience, it doesn't take that long. A 40 minute file takes about <3seconds to run though. Remember that the "^M" is not the 2 characters ^ and M, you have to press Control-V, and then enter. Instead of your command I used: ffmpeg -i somefile.avi -vcodec copy -f rawvideo -y /dev/null 2>&1 | tr "^M" '\n' | grep '^frame=' | perl -pe 's/^frame=\s*([0-9]+)\s.*$/\1/' | tail -n 1 Your command fails if there's no space after the "frames="
