It may happened by ffmpeg didn't release the previous session of /dev/video0. The format option may be needed for raw input files. To force the frame rate of the input file (valid for raw formats only) to 1 fps and the frame rate of the output file to 24 fps: ffmpeg -r 1 -i input.m2v -r 24 output.avi. The -c copy argument tells it to copy all input streams (audio, video, and potentially others, such as subtitles) into the output as-is.

It seems like ffmpeg can't access the /dev/video0. ffmpeg -formats grep mp3 check if mp3 format is available ffmpeg -i inputfile.wav -f mp3 outputfile.mp3 Trim a video file Trim a file starting at 4 minutes 41 seconds point and finish after a duration of 54 minutes and 12 seconds: ffmpeg -ss 4:41 -t 54:12-i inputfile.mkv -c:a copy -c:v copy trimmedfilm.
