Embodiment
[0021] refer to figure 1 with figure 2 , this embodiment provides a method for real-time monitoring of playback without plug-ins in the firefox browser:
[0022] WebRTC is a p2p (peer to peer) video conferencing solution based on the html5 standard. The new chrome kernel and friefox kernel browsers have integrated WebRTC. Since WebRTC is only for video conferencing, it only supports the transmission and live broadcast of PC or mobile phone cameras and PC screen streams, and does not support the transmission of third-party video data streams.
[0023] It is time to use WebRTC as the bottom layer of interaction, and change the p2p transmission model of WebRTC to the mcu model (modify the data output mode of the streaming media server to support naked video data stream output);
[0024] Write a transcoding server that transcodes the naked video data stream (H.264 data stream) output by the video monitoring device into the vp8 format supported by WebRTC in real time, and set th...

The present invention provides a method for real-time monitoring without plug-ins in the browser. The method uses WebRTC as the bottom layer of interaction, changes the p2p transmission model of WebRTC to the MCU model; writes a real-time transcoding of the naked video data stream output by the video monitoring equipment It is a transcoding server in vp8 format supported by WebRTC, and the transcoding server is set between the browser and the streaming media server; the output data stream of the transcoding server will distribute the streaming media data through the mcu model in step 1; the browser front end Directly call the interface function provided by the transcoding server to read the data stream and display it in the native WebRTC way. To solve the problem that the current plug-in browser real-time monitoring playback method needs cumbersome plug-in installation, and can only support some platforms, while the existing plug-in-free playback method is complicated to code and will cause a delay of at least 5 seconds. The invention belongs to the field of monitoring and playing.
Description
technical field [0001] The invention relates to a monitoring and playing method, which belongs to the field of monitoring and playing. Background technique [0002] In the context of the increasing development of the network, video surveillance has not only been used for security, but also more home monitoring, and the demand for small-scale civilian monitoring has been continuously raised. Therefore, using the B / S architecture as the video surveillance client can reduce the problems caused by the user's installation of software and facilitate updates. [0003] Suppose there is a video surveillance device (such as a common surveillance camera), and the goal is to view the video stream of the video surveillance device through a browser. The current video surveillance architecture on the B / S architecture is mainly divided into two categories: viewing with plug-ins and viewing without plug-ins: [0004] There are plug-in methods: the plug-in methods mainly include two methods...
