[linux-audio-user] Extracting tracks from DVDs - Linux-audio-user

19 Mar 2007

On Debian based Linux distributions, e.g. Debian Sarge, Fervent-STG, and so
forth, I find the following two command line programs very useful for
extracting and manipulating DVD contents:
dvdbackup  (to get the info on the hard drive)
ffmpeg (for audio and/or video transcoding/format conversion)
They are usually supplied with the distribution itself.  You may need to add
deCSS depending on your region.  Otherwise the dependency issues are not too
bad, unlike dvd::rip
The manual (man) pages are also reasonably complete and clear.
Good luck,
A Nonny Mous

 The problem with all of these applications is that they downmix the
 audio down to stereo when storing to a wav file.
 Do you know if the tccat/tcdecode/tcextract command will save the
 individual tracks (interleaved or otherwise)?
 Thanks,

  dvdrip refuses to work on my distribution.

 mmh then there's the chance that tcdemux & tcdecode won't work either. -
 usually you get those as dependency to dvd::rip.  - see.

 I'm sure that you can also use mplayer/mencoder or some ffmpeg command
 line to do the same job.. gstreamer too..
  Is there a chance you could
 tell me what the tcdemux | tcdecode scripts would be to extract the audio? 
 sorry, I did not have my dvd drive with me.. now I do.
 how are your command line skills? dvd::rip does a lot of fancy piping  (
 `man tee` -> man dvdrip-multitee ? :) ) - the command that does ripping
 & demux is several pages long (includes 100 subtitle commands)...
 It boils down to sth like this:
 tccat -t dvd -T 1,-1,1 -i \/dev\/scsi\/host8\/bus0\/target0\/lun0\/cd  |
 tcextract -a 0 -x ac3 -t vob | tcdecode -x ac3 | tcscan -x pcm
 adjust the device to match your DVD-ROM.  and replace the last step " |
 tcscan -x pcm" with " > ripped-audio.pcm" to write the audio into a
 file; or use " | tee ripped-audio.pcm | tcscan -x pcm" to write to a
 file and scan for peak values..
 use sox or rezound or ... to convert the pcm into your favorite format!
 good luck,
