Live555 -

Live555 是一个为流媒体提供解决方案的跨平台的C++开源项目，它实现了对标准流媒体传输协议如RTP/RTCP、RTSP、SIP等的支持。Live555实现了对多种音视频编码格式的音视频数据的流化、接收和处理等支持，包括MPEG、H.263+、DV、JPEG视频和多种音频编码。同时由于良好的设计，Live555非常容易扩展对其他格式的支持。目前，Live555已经被用于多款播放器的流媒体播放功能的实现，如VLC(VideoLan)、MPlayer。

LIVE555 Streaming Media is a set of open source (LGPL) C++ libraries for multimedia streaming.^[1] The libraries support open standards such as RTP/RTCP and RTSP for streaming, and can also manage video formats such as H.264, MPEG, VP8, and DV, and audio formats such as MPEG, AMR, AC-3 and Vorbis. It is designed in such a way that it can be easily extended to support more formats.

These libraries can be used to implement both RTSP servers and RTSP clients. Several demonstration applications are provided. Its RTSP client implementation is used by several media players, includingVLC media player and MPlayer.
