MPlayer is a movie and animation player that supports a wide range of codecs and file formats, including MPEG 1/2/4, DivX 3/4/5, Windows Media 7/8/9, RealAudio/Video up to 9, Quicktime 5/6, and Vivo 1/2. It has many MMX/SSE(2)/3Dnow(Ex) optimized native audio and video codecs, but allows using XAnim's and RealPlayer's binary codec plugins, and Win32 codec DLLs. It has basic VCD/DVD playback functionality, including DVD subtitles, but supports many text-based subtitle formats too. For video output, nearly every existing interface is supported. It's also able to convert any supported files to raw/divx/mpeg4 AVI (pcm/mp3 audio), and even video grabbing from V4L devices.
LiVES is a simple to use yet powerful video effects, editing, conversion, and playback system aimed at the digital video artist and VJ. It runs under Linux, BSD, Mac OS X/Darwin, IRIX, and openMosix. It is frame and sample accurate, can handle almost all types of video, and is fully extendable through plugins and the included plugin builder tool. It can also be controlled remotely using OSC.
Mjpeg tools is a suite of programs which support video capture, basic editing, playback, and compression to MPEG-1/2 of MJPEG video. The capture software allows MJPEG video streams in AVI, Quicktime, and movtar format to be produced using the Iomega Buz, Miro DC10+, Matrox Marvel, and similar hardware. The editing and playback tools are hardware independent, with support for hardware accelerated playback if present. The MPEG compression tools are based on MPEG Software Simulation Group's reference encoder with enhancements to provide far faster compression and significant quality improvements.
NewVideoRecorder is a high quality video capture toolkit for Linux. It includes deep buffering of audio and video to reduce frame dropping, a smooth dropping algorithm to keep the video smooth if dropping is required, and dynamic stretching of the audio stream to exactly match the video stream. It can use v4l1 and v4l2 devices as video sources, and OSS devices as an audio source. It can produce QuickTime, AVI, NuppelVideo 0.52 files, MPEG-1 files, and all files supported by ffmpeg (through the ffmpeg library). It also includes tools and utilities for high quality video streaming (multicast and unicast).
Libquicktime is based on the quicktime4linux library with several enhancements. All 3rd-party libraries were removed from the sourcetree. Instead, the systemwide installed libraries are detected by the configure script. All original codecs were moved into dynamically loadable modules, and new codecs are in development. Special API extensions allow access to the codec registry and more convenient processing of audio and video data. Libquicktime comes with original utility programs and additional tools, like a command line player and a GTK configuration utility that can configure the parameters of all installed codecs. The configuration is stored in the home directory, and can be used by all libquicktime applications.
bttvgrab is a program for grabbing video sequences using a bt848-based frame grabber card (e.g. Hauppauge WinTV, Miro PCTV...). The goal of bttvgrab is to provide high-quality grabbing suitable for video recording. Currently, this is accomplished by trying hard not to leave out a single frame, and to catch temproary delays by buffering several frames. In the future, synchronized sound will be part of it. Then you can create mpeg movies using mpeg2enc, the output files will be prepared for that, so that the conversion can be done by a simple shell script.
