Hi all!

I need to rip the audio from a DVD. I know it's title 38, chapter 3.

I read i could use tcextract to do this... but how can I tell it to rip chapter 3 in title 38?

Still trying, but i'd be sooo happy if someone could tell me a fast way of doing it...

THX!

Code: Select all

# ls /media/cdrecorder/VIDEO_TS/
VIDEO_TS.BUP  VTS_01_0.BUP  VTS_01_1.VOB  VTS_02_0.VOB  VTS_03_0.IFO  VTS_03_2.VOB  VTS_04_0.VOB  VTS_05_0.BUP  VTS_05_1.VOB  VTS_06_0.IFO  VTS_07_0.BUP  VTS_07_1.VOB
VIDEO_TS.IFO  VTS_01_0.IFO  VTS_02_0.BUP  VTS_02_1.VOB  VTS_03_0.VOB  VTS_04_0.BUP  VTS_04_1.VOB  VTS_05_0.IFO  VTS_05_2.VOB  VTS_06_0.VOB  VTS_07_0.IFO
VIDEO_TS.VOB  VTS_01_0.VOB  VTS_02_0.IFO  VTS_03_0.BUP  VTS_03_1.VOB  VTS_04_0.IFO  VTS_04_2.VOB  VTS_05_0.VOB  VTS_06_0.BUP  VTS_06_1.VOB  VTS_07_0.VOB

I tried this:

Code: Select all

transcode -i /mnt/cdrom/VIDEO_TS/VTS_06_1.VOB -x dvd -y lame -U audiocordy

But i get errors:

mplayer can do it:

Code: Select all

mplayer -dvddevice <dvd-device> dvd://38 -chapter 3-3 -dumpaudio -dumpfile audio_track.out -aid <audio track-id>

<dvd-device>       - This should be the path to your dvd-rom's device node, eg /dev/dvd
<audio track-id>   - This is the ID of the track you want to rip. Use lsdvd to get this, it should be a hex number starting '0x'.

Hope this helps!

EDIT: The above will give you the raw AC3 track, you might then be able to use transcode to do the mp3 conversion.

Try this my brother.

Code: Select all

How can I save the audio track of a DVD directly to a WAVE file suitable for burning onto an Audio CD?

A: Suppose you want the 2nd audio stream from title #2:

      transcode -x null,dvd \
                -i /dev/dvd \
                -T2,-1 \
                -a 1 \
                -y wav \
                -J resample \
                -E 44100 \
                -o foo.wav

The resampling is needed since DVD audio is usually sampled at 48 kHz.

Taken from

http://www.transcoding.org/cgi-bin/tran ... nscode_FAQ

I haven't tried it myself. That should give you a WAVE file. Then use "lame" to enocde it to MP3.

Something to work with anyways.

The resampling is needed since DVD audio is usually sampled at 48 kHz.

That looks like the best solution, if you set the -T flag to '38,3' then that should get you the chunk of audio you want.

I answered this very question not more than two days ago. See Pulling audio off a DVD.
