Problems solved by technology
[0003] However, the real-time performance of video playback using HLS technology is poor, and the video image delay is relatively large (about 10 seconds), which is unacceptable for real-time preview video
Although the video playback solution using WebRTC has a low delay, it does not provide a solution for playing multiple video streams at the same time.

The present invention discloses a WebRTC-based video stream transmission method, device, storage medium and device, comprising: a browser creating the browser and the stream through first session description protocol SDP negotiation with a web page instant messaging WebRTC gateway session between media servers, and establish a first stream channel; the browser obtains a subscription list of video streams, and if the subscription list indicates to subscribe to a video stream, the browser receives the stream through the first stream channel The one video stream sent by the media server; if the subscription list indicates to subscribe to multiple video streams, the browser creates a second stream channel based on the session through the second SDP negotiation with the WebRTC gateway ; The browser receives the plurality of video streams sent by the streaming media server through the second stream channel, so that the browser can simultaneously preview multiple streams based on WebRTC.
Description
technical field [0001] The present invention relates to streaming media transmission technology, in particular to a video streaming transmission method, device, storage medium and equipment based on WebRTC. Background technique [0002] At present, there is an increasing demand for watching videos through browsers without plug-ins. The existing mainstream video playback methods without plug-ins generally use HLS (HTTP Live Streaming, HTTP-based adaptive bit rate streaming media transmission protocol) technology or WebRTC (Web Real-Time Communication, web instant communication) technology. [0003] However, the real-time performance of video playback using HLS technology is poor, and the video image delay is relatively large (about 10 seconds), which is unacceptable for real-time preview video. Although the video playback solution using WebRTC has a low delay, it does not provide a solution for playing multiple video streams at the same time. Contents of the invention [...
