RTSP Like H.323 uses RTP (Real-Time Transport Protocol) to format packets of multimedia content.
But whereas H.323 is designed for videoconferencing of moderately-sized groups,
RTSP is designed to efficiently broadcast audio-visual data to large groups.
RTSP grew out of work done by Columbia University, Netscape and RealNetworks.

Introducing libnms, the Open Media Streaming Client Library
libnms let you add multimedia streaming playback in your applications in a quick and straightforward way.
This software, derived from the experience matured with NeMeSi is fully compliant with IETF's standards for real-time streaming of multimedia contents over Internet.
libnms implements RTSP - Real-Time Streaming Protocol (RFC2326) and RTP/RTCP - Real-Time Transport Protocol/RTP Control Protocol (RFC3550) supporting the RTP Profile for Audio and Video Conferences with Minimal Control (RFC3551).
Currently libnms is relatively stable API wise and the most enlighting documentation are the example code and the partially doxygenized headers.

The (LS)3 - Libre Streaming, Libre Software, Libre Standards (formerly known as OMSP - Open Media Streaming Project) is a free/libre software project for the development of an open platform for the streaming of multimedia contents.
The platform is based on the full support of the IETF's standards for the real-time data transport over IP.
The aim of the project is to provide an open solution, free and interoperable along with the proprietary streaming applications currently dominant on the market.
All (LS)3 software is released under the GNU GPL license.
