See also vobinfo for an alternative to bbDEMUX I’ve never gotten vobinfo to work.Meridian Lossless Packing or uncompressed LPCM ĭVD Books, Part 4, DVD-Audio Book, DVD Audio Recording Book ĭVD-Audio is an audio format similar to the CD. The same or similar techniques will work on AVI files: /Applications/ffmpegX.app/Contents/Resources/ffmpeg -ab 256 -i in.avi out.mp3 Better: /Applications/ffmpegX.app/Contents/Resources/ffmpeg -ab 256 -i in.ac3 out.wav Not exactly the conversion I wanted (I wanted a lossless format) but it will suffice. Given that I was unable to build FFmpeg I was able to use the copy which comes inside the GUI version as follows: /Applications/ffmpegX.app/Contents/Resources/ffmpeg -ab 256 -i in.ac3 out.mp3 I believe that once FFmpeg is successfully built with A52 support that the above PAC invocation will work, although a quick test with the GUI wrapper for FFMpeg (see ) yielded the following: FFmpeg version CVS, Copyright (c) 2000-2004 Fabrice Bellard So I decided to update/recompile my FFmpeg install. Back to trying with PAC: pacpl -ac3towav -file *.ac3įailed: Unsupported codec (id=86020) for input stream #0.0 I decided to forget about trying with VLC. The resulting OGG files couldn’t be played in VLC (why then did it create them with reporting any errors?). I tried transcoding again, this time using FLAC/ OGG instead of FLAC/ RAW. I checked the "raw" files and VLC couldn’t play them despite the fact that it created them, so here I think VLC is to blame. I checked and the FLAC files were white noise as well. flac -d *.flacįinally I had something I could play in iTunes (and there convert to Apple Lossless) but on playing the tracks I discovered that they were all 100% white noise. I then used flac to convert them to WAV format. This time PAC worked and converted the files to FLAC. Then PAC couldn’t find the sox executable so I ended up editing the configuration file at /etc/pacpl/nf.

I was told that I needed SoX, so I installed that (see " Installing SoX 13.0.0 on Mac OS X"). I then tried using PAC as follows: pacpl -rawtoflac -file *.raw I choose to use the FLAC codec because it is lossless, and a RAW container type. From the "File" menu choose "Streaming/Export Wizard".
See " Installing PAC (Perl Audio Converter) on Mac OS X" for a description of using PAC to perform the conversion I’ve never been able to get that technique to work (I always get a message like "Unsupported codec (id=86020) for input stream #0.0"). AC3 conversionĪfter demuxing you will have a bunch of AC3 files, one per VOB, but neither QuickTime nor iTunes can read them. bbDEMUX can fail even on non-copy-protected DVDs, but the MacTheRipper step often helps.
The drag-and-drop feature seems broken in the main window (although dragging to the Dock icon seems to work, as does the "Open" item in the "File" menu). I usually try using bbDEMUX directly on the DVD first and if that fails I fall back to using MacTheRipper to extract the VOB files and then I try running bbDEMUX on those.ībDEMUX is fairly out of date, no Universal Binary version is available, and it runs slowly under Rosetta.

On the other hand, laws like the DMCA make it illegal to circumvent the DRM on DVDs that you’ve purchased, and this DRM prevents you from exercising your Fair Use rights.īecause of the DMCA I am not going to link to software that would enable you to circumvent any DRM, nor will I provide instructions on how to do so. On the one hand, copyright law provides you with " Fair Use" rights that allow you time-shift and format-shift the content you purchased. This information should not be used (and probably wouldn’t help anyway) on copyrighted or copy-protected material. These are notes I made while trying to extract the audio from public domain (not copyrighted) DVDs of live convert performances.
