1) Another live DVD had both a Stereo and 5.1 mix. As the 5.1 was the second audio track, I had to change all the “-a 0″ entries to “-a 1″.

2) I found about half of the files to be unplayable in both VLC and totem. ffmpeg could process them, giving some “incomplete block” and other other errors, but the output files where then okay. Turn out that just dropping the “tcextract” invocation fixed the problem as well. The resulting files are a few 100kb larger, but they all play fine in VLC and totem.

So finally I ended up using the following for the DVD Title 4, Chapters 1-9, Audio Track 0:
for i in {1..9} ; do tccat -T 4,${i},1 -i “/dev/sr0″ -t dvd -d 0 | tcdemux -a 0 -x ac3 -S 0 -M 1 -d 0 > Syschaos_${i}.ac3 ; done

For another DVD (“Where Death is most alive” by “Dark Tranquillity”) I needed Title 1, Chapters 2-21, Audio Track *1*:
for i in {2..21} ; do tccat -T 1,${i},1 -i “/dev/sr0″ -t dvd -d 0 | tcdemux -a 1 -x ac3 -S 0 -M 1 > Deathalive_${i}.ac3 ; done

3) As a side node, when creating MP3 files with transcode, one can alter the default of 128kbit/s using the -b switch, e.g. “-b 256k”.

As this is the first page to come up on Google when searching for “rip dvd audio linux”, I want to share how I succeeded in extracting the 5.1 Audio from a music DVD directly to AC3 files. I could not find any other resources on how to do so without retranscoding or conversion to Stereo Audio.

I could not get direct AC3 extraction to work using transcode, as it would always fail with different errors depending on the “-y” values chosen. But from its output, I could derive how to do it. The following line will extract the multichannel AC3 audio from chapters 1-9 of track 4 of the DVD (“Systematic Chaos” 5.1 Mix DVD from Dream Theater) in the first optical drive in Arch Linux for files “Syschaos_{1..9].ac3″, which just play fine in VLC:

for i in {1..9} ; do tccat -T 4,${i},1 -i “/dev/sr0″ -t dvd -d 0 | tcdemux -a 0 -x ac3 -S 0 -M 1 -d 0 | tcextract -t vob -x ac3 -a 0 -d 0 > Syschaos_${i}.ac3 ; done

The syntax of the tccat “-T” command is identical to transcode’s.

Again, thanks to the author and Ascentury for their valuable information!

I gave up trying to figure out why and instead just used lame to convert my WAV to an MP3

for((x=1; x<=8; x++)) do transcode -i /dev/dvd -x dvd -T 1,$x,1 -a 0 -y wav -m track$x.wav; lame -V2 track$x.wav track$x.mp3; rm track$x.wav; done;

transcode -i /media/cdrom0 -x dvd -T24,1 -a 0 -y raw -m redvsblue_s5.mp3

Is because of people like you this thing called OpenSource works so fine!

for ((w=1; w<=16; w++)) do transcode -i /dev/dvd -x dvd -T 4,$w,1 -a 0 -y raw -m yourartistname-0$w.mp3; done

That is just a repetitive structure, where w represents the first number of the chapter and the second w the last chapter you want to rip. Instead of writing down all the numbers, you can tell the compiler to do it for you. The line where it says “yourartistname” is for you to substitute that for the name of your favorite artist, or the single, or the disc or anything you want.
The output filename will have the number of the chapter next to the name of your artist (specially useful if you want them to be ordered numerically)
I get rid of longer locations in the filenames by locating the parser to the desired directory before executing the preceding order (this is writing cd /yourhomefolder/yourdesiredfolder before executing the order).
But i have a little problem: when i do all that, the file volume is considerably low, so my question is how can i increase the volume level of my output file?
Thanks in advance.

I ripped audio from a dvd but found that there was clipping on some of the louder parts of the music. Is there a way of preventing this? i.e. can you normalize the levels whilst ripping?

thanks for a reply from anyone,
