RFC3984 is the specification of H. Baseline streaming in RTP mode, where only fu-a subcontracting is discussed, as the work is just used, it is written down. Fu_a a kind of fragmented packet, is to encapsulate an oversized Nalu unit into a plurality of RTP packets, which is different from the previous kind of single nalu encapsulated into a single RTP package, of

Why does a host inside Nat have access to a Web server outside of NAT, but cannot get RTSP stream Media server stream? Reason: For protocols such as HTTP, the client establishes a socket connection with the Web server, which is monitored by a Web server that binds a fixed TCP port on this port. Clients located behind the NAT randomly select a TCP port connect (2) WEB SERVER. For RTSP streaming media servers, the use of RTP packaging multimedia load, t

Https://github.com/whtang/GoRTPGORTP implements some important functions that modify the head and contents of the RTP packet. Most, however, handle only the payload and timestamp of the RTP packet.RTP Data groupingThe packet module implements a buffering mechanism that allows for missed calls, which reduces the dynamic allocation request for memory. Although not necessary, it is recommended that freepacket

This example demonstrates how to use the jrtplib library to encapsulate the RTP protocol in Linux. This routine can be used as a basic routine for streaming media transmission. Only the source code is provided here (these can be found in the official jrtplib files) Sender: /** Sending Program (for Windows and Linux)* For IPv4-based transmission routines, a port number and destination address must be provided.* Reference: http://blog.csdn.net/ipromiseu

Some of the things that have been related to the low-latency transmission of the screen in recent time. Originally wanted to use GStreamer to verify that the RTP over UDP transfer h264 NAL data related, the results found that can not use Playbin to play RTP data! Admittedly, this also has its cause because RTP needs some out-of-band data, which is not simply pass

3. Dynamic Distribution and implementation of cache areas. Based on this fact, the audio data is much smaller than the video data. Therefore, the audio buffer and the video buffer are managed separately. According to statistics, the RTP data packet size of the same media stream is similar. For example, the audio size is about several hundred bytes, and the video size is 1.3 Kbytes. The video buffer is divided into two parts. Some are in the Active Dat

We have been able to get video or camera data in the last issue, and we can get the frame data, then we will study RTP in this period and send the data to the target server. Introduction to RTP protocol This is very good for friends: http://blog.csdn.net/bripengandre/article/details/2238818 RTP.NET.dll Core code Explanation Real-time Transport protocol

Real-time Streaming protocol RTSP (Realtimestreamingprotocol) is proposed by RealNetworks and Netscape, which defines how a one-to-many application can efficiently transfer multimedia data over an IP network. RTSP is located on the architecture of RTP (real-time transmission) and RTCP (real-time control), which uses TCP or RTP to complete the data transfer. HTTP transmits HTML compared to RTSP, while

Original link: http://blog.csdn.net/yu_yuan_1314/article/details/8963673 The timestamp field in the RTP package is the synchronization information that describes the time of the packet, and is the key to recovering the data in the correct chronological order. The timestamp value gives the sampling time of the first byte of the data in the packet. In order to calculate the playback time of each data stream and synchronize processing, only the timestam

You need to set the timestamp unit (timestamp) and timestamp increment (timestamp increment) when sending data using Jrtplib. Read some articles on the Internet, carefully wanted to think now just figured out the problem. The RFC3550 description of the timestamp is: A timestamp (timestamp) 32-bit timestamp reflects the sampling time of the first byte in the RTP packet. (The sampling clock must originate from a timely, monotonically, linearly increme

Directly go to the topic. After JPEG compression, the data is transmitted to the network through the RTP/RTCP protocol. This topic uses the RTP/RTCP protocol stack of jrtplib, first, obtain the source code of the jrtplib package on the internet, decompress the configuration, compile and install the package, and OK if no bugs is available. There are several examples in the source code package, which can be u

real-time audio and video domain UDP is the kingly The Transport layer scheme for real-time audio and video interaction on the Internet has two types: TCP (e.g. RTMP) and UDP (e.g. RTP). The TCP protocol provides a relatively reliable guarantee for data transmission between two endpoints, which is achieved through a handshake mechanism. When the data is passed to the receiver, the receiver checks the correctness of the data. The sender only receives t
