RTMP (Real Time Messaging Protocol) live broadcast stream to HTTP FLV live broadcast stream real-time conversion system and working method thereof

Abstract

The invention discloses an RTMP (Real Time Messaging Protocol) live broadcast stream to HTTP FLV live broadcast stream real-time conversion system and a working method thereof. The method comprises the steps that a data separation module receives RTMP live broadcast streams in real time, separates script tags and audio / video data from the RTMP live broadcast streams and stores the script tags andaudio / video data to a message buffer module; a coder module takes out the audio / video data from the message buffer module and carries out FLV format coding on the audio / video data; and after an HTTP service module receives an HTTP FLV live broadcast stream playing request of a playing end (6), the HTTP service module obtains corresponding live broadcast streams from the coder module and sends thelive broadcast streams to the playing end (6). According to the system and the method, on the basis of the existing RTMP live broadcast service, the HTTP FLV live broadcast is seamlessly expanded, sothe device investment and technical modification cost are greatly reduced. Under the condition of not increasing any device and modifying a protocol, the system and the method are seamlessly connectedwith an existing CDN network, live broadcast demands of a PC and a mobile terminal also can be satisfied, moreover, the image shake problem is solved, and an image second opening method is realized.

Description

technical field [0001] The invention belongs to the technical field of Internet audio and video, and in particular relates to a real-time conversion system and a working method thereof from an RTMP live stream to an HTTP FLV live stream. Background technique [0002] In the field of traditional Internet live broadcasting, the PC side uses the RTMP protocol for live video broadcasting. Some domestic CDN servers have disabled the transmission port 1935 of the RTMP protocol, which is not conducive to CDN distribution of the RTMP protocol, but port 80 of the HTTP protocol is reserved, which can effectively distribute content. . Secondly, with the vigorous development of live broadcast services on the mobile Internet, the RTMP protocol cannot be applied to mobile terminals. Therefore, there is an urgent need for a system that can meet both PC-side live broadcast and mobile Internet-side live broadcast. [0003] FLV is a streaming structure, which consists of a file header (FLV h...

Problems solved by technology

[0007] The purpose of the present invention is to: solve the deficiencies in the above-mentioned prior art, provide a kind of RTMP live stream to HTTPFLV live stream real-time conversion system and its working method, solve the problem that the multi-terminal platform live broadcast protocol cannot be unified, and also solve the live broadcast process at the same time There is a phenomenon of jitter in the medium screen and the method of opening the screen of the terminal player in seconds is realized
