atsifodump is a tool for dumping Audio Title Set (ATS) information from DVD-AUDIO discs, in several formats:
- Detailed technical dump
- Cue sheet for embedding in whole-album FLAC files
- Shell script for ripping tracks to individual FLAC files
Typically the ATS info will be found on a DVD-AUDIO disc at /AUDIO_TS/ATS_01_0.IFO. This is the DVD-AUDIO equivalent of the Video Title Set "IFO" files found on DVD-VIDEO discs. The ATS info structure differs somewhat from the VTS info structure, such that tools designed for DVD-VIDEO discs will not work on DVD-AUDIO discs.
Be advised that this tool does not decrypt the CPRM/CPPM encryption found on some DVD-AUDIO discs. However, the IFO files on these discs are not encrypted, so this tool can still parse them.
This tool is intended for use on Linux systems and makes use of certain GNU/Linux code constructs. However, it is mostly portable C99 code, so porting it to other platforms should not be too difficult.
To compile:
$ gcc -std=gnu99 -O3 -o atsifodump atsifodump.c
Run the tool with no arguments for a quick usage summary:
$ ./atsifodump
usage: ./atsifodump [-dcs] [-t<i>] ATS_xx_0.IFO
-d Output technical details (default)
-c Output cue sheet
-s Output shell script
-t<i> Limit to program chain <i>
$ ./atsifodump /media/DVDVOLUME/AUDIO_TS/ATS_01_0.IFO
