You can use mplayer which is a movie player for Linux and UNIX. It can play most MPEG/VOB, AVI, ASF/WMA/WMV, RM, QT/MOV/MP4, Ogg/OGM, MKV, VIVO, FLI, NuppelVideo, yuv4mpeg, FILM and RoQ files, supported by many native and binary codecs. You can watch VCD, SVCD, DVD, 3ivx, DivX 3/4/5, WMV and even H.264 movies, too. The same tool can be used to covert or extract audio from files. The syntax is as follows:
Where,
mplayer -dumpaudio -dumpfile output_filename.mp3 input.video_file.name
- -dumpaudio : Dumps raw compressed audio stream to ./stream.dump (useful with MPEG/AC-3, in most other cases the resulting file will not be playable). If you give more than one of -dumpaudio, -dumpvideo, -dumpstream on the command line only the last one will work.
- -dumpfile filename.mp3 : Specify which file (filename.mp3) MPlayer should dump to. Should be used together with -dumpaudio / -dumpvideo / -dumpstream.
Task: Extract Audio From .AVI File
Type the command as follows to extract audio from clip.avi to clip_track.mp3:$ mplayer -dumpaudio -dumpfile clip_track.mp3 clip.avi
You can play extracted audio with mplayer command itself:
$ mplayer clip_track.mp3
Task: Extract Audio From VCD or DVD Track
The following command will extract audio from vcd track # 4:$ mplayer vcd://04 -cdrom-device /dev/sr0 -dumpaudio -dumpfile /tmp/track04.mp3
The following command will extract audio from DVD track # 4:
$ mplayer dvd://04 -cdrom-device /dev/sr0 -dumpaudio -dumpfile /tmp/track04.mp3
You can extract track 5 to 10 using the bash for loop as follows:
for i in {05..10}
do
mplayer vcd://$i -cdrom-device /dev/sr0 -dumpaudio -dumpfile /tmp/track$i.mp3
done
Task: Extract Audio From Stream
Use the following syntax:$ mplayer -dumpstream http://example.com/xyz/3 -dumpfile /tmp/stream_03.mp3
