Free dvd rippers software for linux

KungFu DVD Ripper is a GStreamer based DVD ripper.

KungFu creates backups of your DVDs, saving them as .oggs on your hard drive. It encodes the backup using patent-free codecs, Theora for video and Vorbis for audio.

KungFu is not designed for producing backups that fit within a certain file size (say, for burning onto CD); instead, it is designed to produce backups of consistent quality while maintaining the lowest average file size possible (for building a video library on your hard drive).

Thoggen project is a DVD backup utility (DVD ripper) for Linux, based on GStreamer and Gtk+.
Note: Thoggen is still beta software, but should work fine nevertheless. Make sure you check the list of known issues.
Thoggen is designed to be easy and straight-forward to use. It attempts to hide the complexity many other transcoding tools expose and tries to offer sensible defaults that work okay for most people most of the time.
Main features:
- Easy to use, with a nice graphical user interface (GUI)
- Supports title preview, picture cropping, and picture resizing.
- Language Selection for audio track (no subtitle support yet though)
- Encodes into Ogg/Theora video
- Can encode from local directory with video DVD files
- Based on the GStreamer multimedia framework, which makes it fairly easy to add additional encoding formats/codecs in future.
Supported formats:
Ogg/Theora:- Theora video with Vorbis audio in an Ogg container (in case you have not heard of Theora before: it is basically what Vorbis is for audio - a patent-free, royalty-free codec that can be implemented by anone and is supported by recent versions of all major media players on all major platforms).
AVI/divx/mpeg4:- More formats, like MPEG4/divx/xvid in AVI etc., will be added once the core functionality has been finished and works reliably.
Thoggen is licensed under the GNU General Public license (GPL).

RipOff is a GTK+ based CD ripper for Linux (and hopefully for other Unix systems once some testing and fixing have been done) that has a simple interface, CDDB lookups, and a plugin-based encoder architecture.
RipOff CD Ripper attempts to appeal to those users who want a non-GNOME dependent CD ripper with a simple interface, or users who just dont like the interfaces of the other GTK+ CD rippers.
Enhancements:
- Added HTTP_PROXY Functionality
- Fixed a bug where for newer versions of GTK "about" dialogue windows were not closing
- FLAC plugin now supports FLAC 1.1.3
- Added an icon for RipOff
- Miscellaneous code cleanups

boot-dvd project contains a couple of Perl-scripts that can be used to create a custom DVD-ISO image (to be burned), that contains user selected Linux boot/live-CD images (only ISOLINUX boot loader supported) in a handy GRUB menu.
Enhancements:
- Many updates and bugfixes were made.

dvd+rw-tools project makes it possible to burn DVD images created by "dvdauthor" or "mkisofs" to DVD+R, DVD+RW, DVD-R, and DVD-RW disks, replacing "cdrecord-proDVD" in many cases.

The package contains "growisofs" to burn DVD images or create a data DVD on the fly, "dvd+rw-format" to format a DVD+RW, "dvd+rw-mediainfo" to give details about DVD disks, and some programs to control the write speed and obtain information from DVD-RAM.

DVD Manager provides an easy-to-use Web-based DVD management tool.

DVD Manager is an e107 CMS plugin. This plugin will enable users to manage their DVD collection and show it to other members via the Web whether it is online or offline.

John the Ripper is a fast password cracker, currently available for many flavors of Unix (11 are officially supported, not counting different architectures), DOS, Win32, BeOS, and OpenVMS.
It supports several crypt(3) password hash types which are most commonly found on various Unix flavors, as well as Kerberos AFS and Windows NT/2000/XP LM hashes.
Several other hash types are added with contributed patches.
Enhancements:
- Bitslice DES code for x86-64 that makes use of the 64-bit mode extended SSE2 with 16 XMM registers has been added for better performance at DES-based crypt(3) hashes with x86-64 builds on AMD processors.
- A new make target for FreeBSD/x86-64 has been added.
