Thoggen is a DVD ripper for Linux within the GNOME project. It is based on GStreamer and Gtk+. The current version can back up DVDs by encoding them using the Ogg Theora video codec.
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 well for most people most of the time. More Info »
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.
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.
