| This page describes how to extract audio from a video. | Other "how to" pages |
The following example shows how to extract audio (file.mp3) from a working video file (file.ts) via command-line:
vlc file.ts --no-sout-video --sout '#std{mux=raw,dst=file.mp3}'
The following example will prevent the GUI from appearing and converts the audio to .wav:
vlc -I dummy --sout "#transcode{acodec=s16l,channels=2}:std{access=file,mux=wav,dst=OUTFILE.wav}" INFILE.mp4 vlc://quit
With this, you can build scripts to mass-convert multiple files, for example in Bash (Linux, Mac OS X) to convert all files ending in lowercase "mp4" you would use:
for i in *mp4; do vlc -I dummy --sout "#transcode{acodec=s16l,channels=2}:std{access=file,mux=wav,dst=$i.wav}" "$i" vlc://quit; done
