rtsp server

The real-time stream protocol RTSP is jointly proposed by RealNetworks and Netscape, which defines how one-to-multiple applications can effectively transmit multimedia data over an IP network. RTSP is located on RTP and RTCP in the architecture. It uses TCP or RTP for data transmission. Specific implementation: Player = manager. createplayer (rtspurl );Player. addplayerlistener (this );Player. Realize ();Vo

With the key points, you can analyze one item at a point.Design IdeasBased on the above analysis, the first choice is to read the RTSP broadcast protocol. We do not need to start from scratch, there are many on the network and RTSP related open source projects can use or learn from, I chose Live555.LIVE555 is a cross-platform streaming media solution that primarily supports the

Netscape. This protocol defines how a one-to-many application can efficiently transmit multimedia data over an IP network. RTSP provides a scalable framework that enables real-time data, such as audio and video, to be controlled and on-demand. Data sources include field data and data that is stored in a clip. The protocol is designed to control multiple data-sending connections, providing a way to select Send channels, such as UDP, multicast UDP, and

the same way as the HTTP1.1, the caching of proxy server "cache" also applies to RTSP, and because RTSP has a re-directed function, the actual load situation can be converted to serve the server, To avoid excessive load concentration on the same server and cause delays.The

applications, the stability of the client is of course also necessary, otherwise the end user can not see how to play.I knew there was an educational client who originally played the HTTP stream with the player and needed to play different files, and the result was always a problem.If the server side to convert different files to rtmp stream, the client can always play;The customer after the rtmp scheme, after the CDN distribution, did not hear the c

live queue, and the server will put the data in the live queue,If more than this length is emptied to the last I frame:Of course this cannot be configured too small,For example, GOP is 1 seconds, queue_length is 1 seconds, this will cause 1 seconds of data will be emptied, will cause jumping.There's a better way? Some.Latency is basically equal to the client's buffer length because the latency is mostly due to low network bandwidth,

serial number. Timestamp: 32 bits, timestamp. Indicates the sampling time of the first byte in the information packet carried by RTP packet. SSRC: 32 bits, data source ID. Each data stream in an RTP session should have a different SSRC. CSRC list: 0 to 15 items. Each source ID is 32 bits, which contributes to the data source ID. It is valid only when mixer exists. For example, if a multi-channel speech stream is merged into a single-channel speech stream, the SSRC of each original audio channel
