SMPlayer is a complete media player for Windows and Linux. It uses MPlayer as a playback engine, which is capable of playing most video and audio formats (AVI, mkv, WMV, MP4, MPEG, etc.). It can also play and download YouTube videos. One of the most interesting features is that it remembers the settings of all files you play. So if you start to watch a movie but have to leave, when you open that movie again it will resume at the same point you left it, and with the same settings: audio track, subtitles, volume, etc.
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.
SWFTools is a collection of code for handling Flash .SWF-files. This includes a merging tool (swfcombine), an extracting tool (swfextract), PDF/JPEG/PNG/AVI/TTF/WAV to SWF converters (pdf2swf, jpeg2swf, png2swf, avi2swf, font2swf, and wav2swf), a text parsing tool (swfstrings), an SWF parser (swfdump), and a library for writing and reading SWFs (rfxswflib).
Mediastreamer is a portable C library that allows you to create and run audio and video streams. It is designed for any kind of voice over IP applications. It features RTP connectivity, audio codecs (Speex, iLBC, G711, GSM, and AMR), video codecs (MPEG4, H263, H264, and Theora), sound card I/O, wav file streaming, webcam video capture, echo-cancellation, conferencing, parametric equalization, and various other utilities. It has a modular design that makes it extensible through plugins. This is the media-streaming component of linphone, a GPL SIP video phone.
Linphone is an audio and video Internet phone with GTK+ and console interfaces. It uses the SIP protocol, and is compatible with most SIP clients and gateways. It can use various audio and video codecs such as Speex, GSM, G711, G722, ilbc, amr, Theora, H263-1998, MPEG4, H264, VP8, and snow.
Advene (Annotate Digital Video, Exchange on the NEt) is aimed at providing a model and a format to share annotations about digital video documents (movies, courses, conferences, etc.), as well as tools to edit and visualize the hypervideos generated from both the annotations and the audiovisual documents. Teachers, moviegoers, etc. can use them to exchange multimedia comments and analyses about video documents. The project also aims at studying the way that communities of users (teachers, moviegoers, students, etc.) will use these self-publishing tools to share their audiovisual "readings", and to envision new editing and viewing interfaces for interactive comment and analysis of audiovisual content.
The GNU Compact Disc Input and Control library encapsulates CD-ROM reading and control for applications wishing to be oblivious to the OS- and device-dependent properties of a CD-ROM. It provides an API for access to SCSI-MMC (multimedia commands) and support for CD image types like BIN/CUE, cdrdao's TOC, and Nero's NRG, which gives applications using the library the ability to read disc images as though they were CDs. ISO-9660 filesystem support is included, as are utility programs for displaying CD and CD-ROM drive information, reading the blocks of a CD, and extracting files from an ISO-9660 filesytem image. cdparanoia is also included.
