Abstract

The invention provides a method for supporting equipment of a GB / T28181 protocol to check in a mainstream browser. The method comprises the following steps: a LiveServer end realizes an SIP through Node.js, establishes a session with the GB / T28181 protocol, calls a video stream and receives and processes a Web request; the Transcode Server end obtains a video stream, converts the video stream into FLV through FFmpeg, and pushes the FLV to the MediaServer end; the MediaServer end receives the RTMP video stream, packages the RTMP video stream into FLV and distributes the FLV to the Web end; and the Web end obtains the video stream from the MediaServer end and performs video playing. According to the invention, data processing is carried out through mutual cooperation of a plurality of servers, and a GB / T28181 protocol is converted into a protocol capable of being transmitted through HTTP, so that video viewing and equipment control at a browser end are realized.

Description

technical field

[0001] The invention relates to the technical field of computers, in particular to a method for viewing devices supporting the GB / T28181 protocol in mainstream browsers. Background technique

[0002] Usually, the Chrome browser plays video through the Video tag, supports H264 encoded MP4, but does not support H265 encoded MP4, Chrome can also pass the fragmented H264 video and AAC audio to Video for video processing through the MSE (Media Source Extensions) interface For playback, flv.js is such a web-side library, which is used to decode the FLV video transmitted through HTTP, decode the H264 video and AAC audio, and pass it to the Video tag for playback. The disadvantage of this solution is that it does not support H265 encoded video.

[0003] The Chrome Web page supports the HTTP protocol, but does not support the TCP / UDP protocol, and the GB28181 protocol is based on the TCP / UDP protocol, so the GB28181 device cannot be connected directly through the bro...
