CDimg|tools is a set of commandline tools to inspect and manipulate CD/DVD optical disc images in formats uncommon on free Unix-like systems (like GNU/Linux or BSD). It makes it possible to convert .NRG Nero images, 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.
dvdspanky is a CLI tool for converting video files into DVD compatible MPEG streams. It is designed to be easy to use no matter the input source, to automate common transcoding tasks, and provide powerful features such as specifying the destination file size and calculated clipping and letter-boxing. It provides a front-end to transcode, MJPEG tools, mplayer, and feh. The output is ready to use in programs such as dvdauthor.
DVDripTools is a collection of scripts that operate DVD ripping tools. It consists of ripdvd, which creates an MKV, OGM, or MP4 file container very easily; ripdvdcrop, which detects the cropping to use when ripping a DVD; and ripdvdtest, which performs a ripping test of a few seconds.
vobps2fix is a tool that runs through a set of .VOB files created by dvdauthor and tweaks them so that the Playstation 2 will play them without pausing. The Playstation 2 is a bit finicky about the DVD format and pauses frequently when encountering certain timestamps, even if the DVDs work on other players.
vobwalker walks through a .VOB file containing DVD video and extracts lists of VOBUs to a set of chapter files. Each file begins with a VOBU that has no predecessor (i.e., does not point at a preceding VOBU) and contains the list of VOBUs found by following the successor pointers along the list. Although it does not adjust the pointers in the VOBUs (but merely copies them from one file to another), the created chapter files are suitable for use by a program such as dvdauthor that expects to be responsible for filling in the VOBUs.
