libbgrab is a video4linux grabbing library to facilitate use of framegrabber cards and webcams through a few function calls. To implement constant throughput and to avoid frame loss delays, triple buffering is used through local buffer copying in a separate grabbing thread. The many demo and utility programs included can display live video to X, convert live video to ASCII, smoothly zoom live-video (using Glide), do some image processing (using MMX), and provide a stand-alone webcam image server.
The MPEG4IP package provides a set of tools to encode, stream, and playback audio and video. It uses the MPEG-4 standards for audio and video, and the IETF standards for streaming. The included player can either playback from local MP4 file or stream from a remote server via RTP/RTSP.
Dirac is a general-purpose video codec aimed at resolutions from QCIF (176x144) to HDTV (1920x1080), progressive or interlaced. It uses wavelets, motion compensation, and arithmetic coding, and aims to be competitive with other state-of-the-art codecs. The Open Source implementation provides a C++ library with an encoder and decoder.
Schrödinger is an implementation of the Dirac video codec, a modern wavelet-based video codec. It features both an encoder and a decoder and GStreamer plugins. Mappings have also been developed for putting Dirac into both the Ogg container format and the MPEG Transport stream container format.
