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.
RealPlayer plays streaming audio and video over the Internet in real-time. It plays RealAudio, RealVideo, MP3, 3GPP Video, Flash, SMIL 2.0, JPEG, GIF, PNG, RealPix, RealText, Ogg Vorbis, and Ogg Theora. It is available for Windows, Macintosh, Pocket PC, Nokia 9200 Series, Nokia 7650, Palm OS 5-based handhelds, Linux, Solaris, and many Unix variants.
GImageView is a GTK+ based image viewer. It supports tabbed browsing, thumbnail table views, directory tree views, drag and drop, reading the thumbnail cache of other famous image viewers, and a flexible user interface. It also support movies using the Xine library and MPlayer, and supports images in compressed archive formats like tar.gz, zip, and lha.
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.
Coherence is a set of DLNA/UPnP devices, like MediaServer and MediaRenderer. In addition, it includes a well-designed framework to extend other applications with DLNA/UPnP functionality. It also has an emerging DBus API, enabling these applications to participate in digital living networks. It supports Playstation 3 (PS3), XBox, and many other devices.
yet another yuv viewer (yay) displays 4:2:0, 4:2:2, 4:0:0 YUV, and Y-only pictures and sequences (planar Y:U:V format). It tries to find geometry information such as _widthxheight somewhere in the path and filename (e.g. mobile_352x288.yuv or path/to/yuv/mobile_640x480x400frames/file.yuv).
Elisa Media Center is a project to create a media center solution for GNU/Linux and Unix operating systems. Elisa runs on top of the GStreamer multimedia framework. In addition to personal video recorder functionality (PVR) and Music Jukebox support, Elisa also interoperates with devices following the DLNA standard, like Intel's ViiV systems.
