Real-time streaming media (real-time streaming media distribution platform)

RTMP real-time message transfer protocol is FlashAIR platform and supports RTMP protocol.Real-time streaming mediaThe protocol for audio, video and data communication between streaming media interaction servers based on RTSP is an application layer protocolReal-time streaming mediaMultimedia streaming HLS;, which is used to control sound or video, is used in the process of setting up IPCamera project serverReal-time streaming mediaI encountered the demand for real-time streaming media transmission because of the limitations of NAT devices and IPv4 resources, some devices could not transmit point-to-point streaming media directly, which prompted me to turn to the server for forwarding. I chose the mainstream RTMP protocol as the solution. My project design includes self-built RTMP streaming media server and the use of cloud services, while considering non-streaming data transmission, I also need a custom media. There are mainly the following video surveillance protocols: 1 RTSP protocol RTSPReal Time Streaming Protocol is a real-time streaming media protocol, which is used to describe the control operation of streaming media transmission. it allows the client to send requests to the server and controls the transmission of streaming media data, such as playback pause scaling and other video surveillance systems, RTSP is usually used with multimedia transmission, such as RTP real-time transport protocol 2 RTP protocol RTP.

Streaming media protocol RTSPReal Time Streaming Protocol is an important protocol for real-time streaming media transmission, which is proposed by Real network and Netscape. It is used for efficient transmission of audio, video and other real-time data over IP networks based on the RFC 2326, 457, and 6064 specification. RTSP uses 3 RTSP application scenarios RTSP is widely used in video conferencing, distance education, real-time music playback and other occasions that require real-time transmission of audio and video data. Because it supports real-time streaming media, RTSP can help these application scenarios provide a better user experience. At the same time, because it is based on text protocol, it has good scalability and flexibility. With the continuous development of streaming media technology, RTSP will continue to play an important role in Streaming media is a real-time transmission of multimedia data streaming media, the essence of streaming media is to transmit a series of data streams over the Internet, so that users can watch or listen to these data streams in real time on the client side, which mainly includes audio, video or other multimedia content, which is sent in the form of a data stream during transmission. And real-time broadcast on the user's device the following is the main type of streaming media 1 live streaming media this is a real-time transmission.

(2) Real-time streaming ensures that the media signal bandwidth can match the current network situation, so that streaming media data is always transmitted in real time, so it is especially suitable for real-time streaming of live events to support random access, that is, users can watch the front or back content through fast-forward or backward operations. in theory, real-time streaming media will not stop once it is played. But in fact, periodic pauses are still possible. OBS, or Open Broadcaster Software, is a free and open source tool widely used in video recording and real-time streaming media. It occupies an important position in the live broadcast industry and is favored by anchors because of its powerful features. Although the choice of live broadcast software depends on personal preference, OBS occupies a dominant position in the live broadcast field because of its characteristics. OBS has many practical functions. First of all, it supports efficient H264X264 coding and AAC coding to ensure video.

Real-time streaming transmission means to ensure that the media signal bandwidth matches the network connection, so that the media can be viewed in real time and the real-time stream The definition of streaming media transmission is very broad, which mainly refers to the technology of transmitting media such as video and audio through the network. Its specific meaning is to transmit film and television programs to a PC through Internet to achieve streaming transmission. There are two methods of real-time streaming transmission Real time streaming and sequential streaming transmission progressive streaming sequential streaming transmission is a sequential download during transmission not according to the speed of the user connection.

Streaming media English Streaming media refers to the technology and process of compressing a series of multimedia materials, transmitting data in segments over the Internet, and transmitting video and audio on the Internet in real time for viewing. This technology enables data packets to be sent like a stream. If you do not use this technology, you must download the whole media file before use. Real-time streaming media refers to the real-time transmission of Internet content. It's like a live TV broadcast through a television signal. As a real-time streaming protocol control protocol and data protocol, RTSPRTCPRTP jointly builds the basis of audio and video live streaming, which is suitable for different application scenarios and requirements. RTSP provides a controlled and on-demand mechanism for real-time streaming media, and is the core of the streaming media presentation protocol. It is responsible for defining the operation method and status code of control messages, interacting with RTP to achieve the functions of playback pause and fast forward, RTCP and RTP to work together to ensure that packets are transmitted sequentially.

HEIRO network real-time streaming media platform shows remarkable advantages by virtue of four major technological innovations: 1 Fast addressing and positioning HEIRO adopts virtual hierarchical organization technology, when users play programs, the system automatically assigns global and unique node identities, combined with static and dynamic routing strategies, ensures fast and accurate P2P user node location, and optimizes P2P transmission performance 2 saves network bandwidth HEIRO network architecture and ISP synchronization Restrict P2P traffic on the local network to avoid In the project, the technical team of Zanthoxylum bungeanum innovatively designed a real-time interactive streaming media player. The front-end work for the viewing experience of live variety shows is mainly focused on the production of a PC main site. The home page of the site needs to integrate a player to support FLV live video streaming. At the same time, when users click the video review button, a pop-up window can play HLS video streams. At first, the project team adopted flvjs and hlsjs libraries. Output via videojs There are many streaming formats, including RTSPRTMP.
