How can I strip the audio track out of a video file with FFmpeg?
You remove audio by using the
ffmpeg -i example.mkv -c copy -an example-nosound.mkv
Full ffmpeg documentation here.
You probably don't want to reencode the video (a slow and lossy process), so try:
ffmpeg -i [input_file] -vcodec copy -an [output_file]
(n.b. some Linux distributions now come with the avconv fork of ffmpeg)
avconv -i [input_file] -vcodec copy -an [output_file]
If you cannot install
ffmpeg because of existing of
avconv try that .
