Ripped Music DVD Gotchas
Posted by: Mr Underhill on 10 June 2012
Just finished ripping all my music DVDs, and thought I'd note a few of the techniques I have used.
I am working on Linux, but much of the software is available for Windows.
In an earlier post I wrote how I was ripping to mkv, mkv being a container that can hold an audio and a video stream:

This generally works as advertised via MakeMkv ....but, you often end up with a large single mkv file.
This is fine in many players, such as VLC, as the chapters have been ripped as well ...but, my BlueRay players see the one file as a chapter, which is a pain.
The solution I have used is to divide the large file into smaller ones, based on the captured chapters.
Dividing Music MKV file into Smaller Track Based Files
Load and use MkvMerge.
1. Add the target ripped mkv file via add on the Input tab.
2. Go to the toolbar, select Chapter Editor > Load, and load the SAME file.
This iterates through the file and captures the chapter detail, which is then displayed
in the Chapter Editor tab.
3. Go to the toolbar, select Chapter Editor > Load, and Save As, give the file a name.
4. Open the file in a text editor. Delete everyting APART from the times, which you seperate
with a comma.
5. Go to the Global tab.
Click Enable Splitting and link files.
Select '...after timecodes:' and paste the comma delimited times into the dialogue box.
6. Check the Output filename, and ensure the files will be called something you
find acceptable.
7. Click 'Start Muxing'.
You're done.
MKV Reports No LPCM Filter When Ripping DVD With PCM Soundtrack
Every now and then MakeMkv fails to rip a PCM soundtracked DVD, reporting that it is missing a filter. I believe this MAY be due to mis-reporting of the LPCM track type.
To get round this I:
1. Use MakeMkv to JUST rip the VIDEO - de-select the PCM soundtrack;
2. Load & use DVD::Rip to rip the DVD to a series of VOB files;
3. 'cat' the tracks to create a single VOB file, e.g.
cat dd-001.vob dd-002.vob dd-003.vob dd-004.vob > bld.vob
4. Use mplayer to extract the PCM soundtrack:
mplayer -vc dummy -vo null -ao pcm:file=bld.wav bld.vob
5. Mux the two files together using MkvMerge -> mkv file.
On the Input tab add both the video & wav files, click 'Start Muxing'.
Getting WAV file From MKV
There is music on many of my music DVDs that I would like to listen to via the NS01, and unfortunately I don't think name are going to set up the box to stream mkv files any time soon!
In Linux I:
1. Rip the mkv - as previous thread;
2. Divide the mkv into tracks - as above;
3. Go to the command line and move to the directory containing the files I want to
extract the WAV from;
4. Use this command:
find . -type f -exec ffmpeg -i '{}' -vn -acodec copy '{}'.wav \;
Hope this may be of assistance to you.
