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.
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.
Xvid (formerly XviD) is an open source MPEG-4 video codec, implementing MPEG-4 Simple Profile, Advanced Simple Profile, and Advanced Video Coding standards. It is written in C with assembler optimizations for quality and speed (including MMX, SSE, and 3Dnow! code for i386 and AltiVec for PowerPC), and is especially optimized towards offline, multi-pass compression for storage and archival purposes.
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.
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).
The VideoLAN Server (VLS) can stream MPEG-1, MPEG-2, and MPEG-4 files, DVDs, digital satellite channels, digital terrestial television channels, and live videos on a network in unicast or multicast. A VideoLAN Client (VLC) or a set top box can receive the stream, decode, and display it.
pHash is an implementation of various perceptual hashing algorithms. A perceptual hash is a fingerprint of a multimedia file derived from various features from its content. Unlike cryptographic hash functions that rely on the avalanche effect of small changes in input leading to drastic changes in the output, perceptual hashes are "close" to one another if the features are similar. Potential applications include copyright protection, similarity searches for media files, or even digital forensics.
Minitube is a YouTube application for Mac, Linux, and Windows. With it, you can watch YouTube videos in a new way: you type a keyword, and Minitube gives you an endless video stream. Minitube does not require the Flash Player. It is not about cloning the original YouTube Web interface, but strives to create a new TV-like experience.
