I changed the motherboard.The code is very detailed and the example is clear.Thank you for your repeated replies. :) For more comments.# Re: H.264 RTP payload format 2010-01-29 09: 11asd Hao replies to more comments# Re

RTP Message Format The RTP message consists of two parts: header and payload. The RTP header format is shown in the following illustration, where: L The version number of the V:RTP protocol, which accounts for 2 digits, and the current protocol version number is 2. L P

The data in the live555 is sent in the end to be sent using the RTP protocol, which describes the RTP package format.RTP PacketRTP is based on the UDP protocol, and the RTP server passes the UDP protocol, typically sending an

in streaming media technology.H.264/AVCIt is a new generation of video coding standards jointly developed by a Joint Video group (JVT) consisting of the ITU-T video coding Expert Group (VCEG) and the ISO/IEC dynamic image Expert Group (mPEG, its biggest advantage is its high data compression ratio. h. 264 of the compression ratio is more than 2 times of the MPEG-2, is the MPEG-4 of 1.5 ~ 2 times. At the same time, the layer design of the video encoding layer (VCL) and network extraction layer (

I was recently depressed by the load type and timestamp of RTP. After debugging for nearly a week, I finally solved the problem. Let's look back, I found that the main reason is that I did not really understand the meaning of the load type and timestamp in the RTP protocol. Although RTP transmission is supported by Jrt

The RTP receiving part is relatively simple (you do not need to consider jitterbuffer and so on). Start with here. In fact, there are three steps: 1. Create a UDP listener, such as 5200. 2. After receiving the RTP package, send it to the unpacking program and continue receiving the second one. 3. After one frame is collected, the file is saved or decoded to play the video. The following describes the specif

-bit length fields that provide the number of 32-bit characters in the extended header except the first 4 bytes (So 0 is valid ). A maximum of one extension header can be appended to the RTP Header. In order to allow multiple interoperability for independent testing of different header extensions, or to allow a specific implementation of additional header extensions, the header 16 bits of the header extension are reserved as differentiated identifiers

stream. (4) The streaming media server uses the RTP/UDP protocol to transmit audio/video data to the client. Once audio/video data arrives at the client, the audio/video client program can play the output. It should be noted that in stream transmission, two different communication protocols, RTP/udp and RTSP/tcp, are used to establish a connection with the Strea

Normally, RTSP provide streaming over UDP. By nature, UDP are a better choice as it provides robust streaming capability for media. However, it's unlikely to use UDP for streaming over the Internet.Typically, RTSP provides a UDP way to send RTP streams. Of course, UDP is often a better choice when sending streaming media.However, it is not possible to send a stream using UDP on the Internet. Some issues with UDP is the following are some problems when

RTP packet: a packet with an RTP header on the start, that is, RTP packet. Generally, in the bottom layer protocol, a packet contains only one RTP packet, but through some special encapsulation methods, the bottom layer packet can also contain more than one

byte of the data in the RTP group. The initial timestamp values at the beginning of a session are also randomly selected. Even if no signal is sent, the timestamp value increases with time. The receiving end uses a timestamp to accurately know at which time the data block should be restored to eliminate the jitter during transmission. Timestamp can also be used to synchronize audio and image in a video application.The
