rtsp server

RTSP protocol. The complexity of the RTSP protocol family is mainly concentrated on the server side, because the server side need to parse video files, seek to specific video frames, and may also need to perform speed play (that is, the old DVD with the kind of twice times, 4 times times the function of the speed play

imagery , and allows simultaneous multiple streaming requirements control, and the network protocol used to transmit it is not within its definition. The server side can choose to use TCP or UDP to transmit the stream content, its syntax and operation is similar to HTTP 1.1, but does not particularly emphasize time synchronization, so the comparison can tolerate network latency. In addition, the previously mentioned allow for simultaneous multiple st

, quality reduction; second, advanced and efficient compression algorithms.Basic Principles The process of stream transmission is generally as follows: (1) After selecting a first-class media service, the web browser and the Web server use HTTP/tcp to exchange control information, in order to retrieve the real-time audio/video stream data to be transmitted from the original information. (2) The web browser on the client starts the Client Program (some

) The HTTP protocol does not have a specific transport stream. (4) HTTP transmission generally requires 2-3 channels, command and data channel separation.Second, the available live stream addressUsually when we do RTMP/RTSP development, we can build our own video server for testing. You can also directly use some of the TV station's live address, save time and effort.Here are some of the video live addresse

With the arrival of 3G, the bandwidth is higher and the traffic fee is lower, and multimedia applications such as mobile phone and TV will surely develop greatly. I will sum up my previous experience, I will discuss with you how to create a VoD solution for mobile phones, and finally provide a preliminary client implementation result. Welcome to the discussion. First, let's talk about the architecture. For ease of management and expansion, bandwidth restrictions, and multi-user concurrency, comm

Recently, due to the need to implement RTSP-based transmission RM rmvb, no existing solutions have been found on the Internet. Only one live555 has implemented the RTSP service, but only supports RTP transmission of mpg, MP3, WAV and other formats. rm seems very unpopular in the Open Source Field, probably because the formats and protocols are private and not open. Then we started to develop rmvb over

common monitoring and meet special requirements such as mobile phone monitoring. Considering the actual bandwidth and decoding capabilities of the network, we recommend that you use the resolution of CIF or qcif on your mobile phone. The frame rate should be lower than 15 frames. Shows the software framework: The net engine module is mainly responsible for obtaining data from the video server and implementing an

data packets. therefore, the server can dynamically change the transmission rate or even the type of the payload. RTP and RTCP can be used together to optimize transmission efficiency with effective feedback and minimal overhead. Therefore, it is particularly suitable for transmitting real-time online data. RTSPReal-Time Streaming Protocol (RTSP) is proposed by Real Networks and Netscape. This Protocol def

the difference between hls,http,rtsp,rtmp protocols: in HTTP mode:The FLV is downloaded to the local cache by the server, and then the FLV is played back through the local connection of the netconnection, which is to play the local video, not the video of the playing server. So this flv can be found in the local cache. The advantage is that the

The rtsp is paused. the Mapache + php tool mplayer + vlc function enables camera recording and playback (only playback is used here). The technical route is recorded by mplayer. after recording, the recorded video files are played using the rtsp protocol, and the vlc is used as the rtsp server. the player control inser
