[ excerpt from developer's site ] - What is GStreamer? GStreamer allows the construction of graphs of media-handling components, ranging from simple mp3 playback to complex audio (mixing) and video (non-linear editing) processing. Applications can take advantage of advances in codec and filter technology transparently. Developers can add new codecs and filters by writing a simple plugin with a clean, generic interface. GStreamer is released under the LGPL, with many of the included plugins retaining the license of the code they were derived from, usually GPL or BSD. - Features: * Comprehensive Core Library * Intelligent Plugin Architecture * Extensive Development Tools - Is GStreamer a media player? No, GStreamer is a development framework for creating applications like media players, video editors, streaming media broadcasters and so on. That said, very good media players can easily be built on top of GStreamer and we even include a simple yet functional mediaplayer with GStreamer called Gst-Player

[ excerpt from developer's site ] matroska is a project aiming to become the standard of Multimedia Container Formats one day. It was derived from a similar project called MCF, but differentiates from that significantly because it is based on EBML (Extensible Binary Meta Language ), a kind of binary version of XML. This way the development team gains significant advantages in terms of future format extensability, without breaking file support in old parsers. Advanced because it is based on EBML, a kind of XML equivalent, that allow infinite extensibility of the format. And full featured because it includes precise seeking, any audio/video/subtitle codec support including VCM/ACM/DirectShow compatibility, timecode based format, complex frame dependencies, chaptering, internationalisation, error protection, tagging, file attachement, control track (to be defined), menu (to be defined), etc. All these features are not yet implemented but already defined in the format.

HandBrake is an open-source, GPL-licensed, multiplatform, multithreaded video transcoder with rich selection of features. Both GUI and command-line only versions are available. Supported sources: * Most common multimedia files that libavformat and libavcodec support * Any DVD or Bluray-like source which is NOT copy-protected (removal of copy protection is not supported) Outputs: * File (container) format: MP4 (M4V) and MKV * Video: H.264 (x264), MPEG-2/MPEG-4 (ffmpeg), or Theora (libtheora) * Audio: AAC, CoreAudio AAC/HE-AAC (OS X only), MP3, FLAC, AC3, or Vorbis; AC-3, DTS, DTS-HD, AAC, and MP3 pass-through HandBrake also includes support for chapters, subtitles, advanced video filters, and more. It is also useful for making videos compatible with portable video devices such as the Apple iPod/iPhone.

dvdrip is a Command Line Tool to make a copy from a Video DVD for private Use. It automates the process of Ripping, Authoring, Preview and Burning of a DVD. Features: - Automatic Selection of the longest Title - Automatic Calculation of Factor to Requant - Automatic Read of Volume-ID - Automatic Chapter Separation from Original - Ripping of Audiotracks in every Language - Selection of dts-Audiotracks as Default - Selection of two Subpicture-Tracks possible - Ripping and Re-Authoring - Preview of VOB-Files with mplayer or xine - Burning with growisofs or cdrecord-prodvd - All Program Parameters could be stored in a Config File as Program Defaults - All Paramaters can be overwritten on the fly at the Command Line - Program with english, french or german Messages - Rip of Subpicture-Tracks - Copy DVD < 4.7 GB with Menus; > 4.7 GB with vamps, without Menus. - Partial Copy: Copy selected Titles from a DVD (dvdunauthor/vamps) - High Quality Backup (1 DVD9 => 2 DVD5) - DVD with Menus for Title-, Audio- and Chapter Selection (dvdwizard)

OpenQuicktime aims to be a portable library for handling Apple's QuickTime(TM) popular media files on Unix-like environments. This project was firstly designed to allow the porting of the 3ivx codec on any Unix, but is now a completely separate and fully Open Source project. Details: - OpenQuicktime library contains no embedded codecs but has a plugin system to dynamically load audio and video codecs. - OpenQuicktime contains no colorspace conversion algorithm. - OpenQuicktime is fully portable and fully configurable with all the autoconfigure and automake magic we have been able to add. - OpenQuicktime supports compressed headers (decoding only for the moment). - OpenQuicktime supports Quicktime Sound System version 2. - OpenQuicktime can support any inputs and outputs (file, HTTP, FTP, RTP, ...), in fact the functions used to read, write and seek are overloadable. - OpenQuicktime has an overloadable plugin mechanism. This is a complex feature which enables any application to use its own codecs instead of the OpenQuicktime ones.

K9Copy is a small utility which allows copying DVDs. The DVD video stream is compressed by the program Vamps. 1. Copy without menus: Here, dvdauthor creates a new structure for the DVD. It is possible to arbitrarily set the order of the videos. 2. Copy with menus: Because dvdauthor can't copy the original menus, K9Copy recreates the original DVD structure. The menus as well as IFO files are modified to point to the compressed MPEG2 stream. Creating personalized menus was not brought back with version 1.0.0 Features * The video stream is compressed to make the DVD fit on 4.7 Gb recordable DVD * DVD Burning * Creation of ISO images * Choosing which audio and subtitle tracks are copied * Title preview (video only) * The ability to preserve the original menus

The Kaa Media Repository is a set of python modules related to media. Kaa modules are based on parts from Freevo and modules created for MeBox. Kaa exists to encourage code sharing between these projects, and to serve as an umbrella for several previously disparate media-related modules in order to make them available from one (unique) namespace. Kaa provides a base module that implements the common features needed for application development, such as mainloop management, timers, signals, callbacks, file descriptor monitors, etc. Kaa's other modules provide specific media-related functionality, such as retrieving metadata on arbitrary media files (kaa.metadata, previously called mmpython), Python wrappers for Imlib2, Xine, and Evas, and many other high level APIs for easily creating applications that deal with video and audio. Kaa is named after the python character in the Jungle Book by Rudyard Kipling.
