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.
VLC media player is a multimedia player, framework, streamer, and encoder. It can play inputs like files, network streams, DVDs, audio CDs, Blu-Rays, capture devices, and screens. It can play most audio and video codecs and formats (MPEG 1/2/4, H264, VC-1, DivX, WMV, Vorbis, AC3, AAC, MKV, etc.), but can also be used to convert to different formats and/or send streams through the network.
Blender is a free 3D animation studio. It includes tools for modeling, sculpting, texturing (painting, node-based shader materials, or UV mapped), UV mapping, rigging and constraints, weight painting, particle systems, simulation (fluids, physics, and soft body dynamics and an external crowd simulator), rendering, node-based compositing, and non linear video editing, as well as an integrated game engine for real-time interactive 3D, and game creation and playback with cross-platform compatibility.
RHEED for Linux is designed to aquire data from RHEED (Reflection High Energy Electron Diffraction) images in Molecular Beam Epitaxy and for controlling an electron beam gun. It is possible to determine growth rate of a semiconductor crystal from RHEED-Oscillations, to aquire Lines Of Interest (LOIs) in realtime, and develop incident angle dependent intensity curves. The Electron Beam Gun EK35BR from Staib Instruments is supported.
mpeg2videotools is a C library and set of tools for encoding, decoding, verification, and analysis of MPEG-2 video. Designed for completeness and correctness rather than speed, it supports 422 Profile and High Profile bitstreams. A PSNR tool is included for comparing uncompressed video to encoded MPEG-2 video.
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.
Twibright Luminaplex and Hyperluma 2 are two algorithms and an example implementation developed to encode (chroma subsample) Y'CbCr video at 4:2:0 and 4:2:2 scheme with higher quality than was currently possible. Ordinary encoding introduces errors, while Luminaplex eliminates virtually all error by finding the values of minimum error. It is published as a prior art to prevent coverage by a software patent.
