CDimg|tools is a set of command line tools to inspect and manipulate CD/DVD optical disc images of formats uncommon on free UNIX-like systems (like GNU/Linux or BSD).
One sort of tool is concerned with a certain special image file format, possibly a non open one. It can print information about an image file in this format, or extract parts of its data (e.g. audio tracks or disc sessions) to files in ``raw'' format, so that they can be further processed by more widely available tools (e.g. for the purpose of playing audio, reading files, burning tracks or sessions to optical media).
- NRG is the only supported format for the present.
Another sort of tool is concerned with the processing of files in a ``raw'' format. It can convert between different variations of formats of the same type, or convert from a raw format to an equivalent well-known self-describing format, or modify the raw data without changing its format. For the present it is possible:
-
to demultiplex RAW+96 image files containing both stream data and sub-channel data,
-
to decrypt CSS-scrambled VOB files,
-
and to decrypt CSS-scrambled DVD Video image files.
CDimg|tools was mainly written under a GNU/Linux OS but should work under other UNIX flavours, and perhaps even on other platforms, albeit maybe only partially (see the file link:INSTALL.html['INSTALL'] for a list of dependencies).
linkpage:raw96cdconv[1]:: This command is a Perl script that demultiplexes/multiplexes stream data (audio, raw data or .iso format data) and sub-channel data from a RAW+96 image file. It handles optical disc images containing stream data and sub-channel data of a given sector at contiguous positions; this kind of image file may be either directly created by a ripping program like readcd(1) or cdrdao(1), or extracted from another image file by nrgtool(1).
linkpage:nrgtool[1]:: This command is a Perl script that reads .nrg images (created by Nero), prints the metadata about the image, and extracts, for each track, the raw data to a separate file; disc types such as CDDA, CD-extra and (multi-session) CD-ROM/DVD-ROM are supported.
linkpage:cssdec[1]:: This command decrypts CSS-scrambled VOB files or streams found on DVD Video discs; the title key is obtained transparently by libdvdcss.
linkpage:dvdimgdecss[1]:: This command decrypts CSS-scrambled DVD Video discs or image files; it writes a similar image file containing the same data at the same location; the UDF filesystem of the disc is left intact.
