Real-time video plugin-free previewing method based on RTSP and real-time video plugin-free previewing system based on RTSP

Abstract

The invention discloses a real-time video plugin-free previewing method based on a RTSP and a real-time video plugin-free previewing system based on the RTSP, the method comprises the following steps:acquiring a real-time code stream from a front-end device; transmitting the real time code stream of the front-end device to a streaming media server through the RTSP; receiving and decoding the real-time code stream in a H.264 format into an original code stream by the streaming media server; by the streaming media server, coding the original code stream into the code stream in a VP8 format, andforwarding the code stream in the VP8 format to each client side browser; and by the client side browser, decoding the code stream in the VP8 format through a Web API based on a WebRTC technology, and directly playing the decoded code stream through HTML5. The system comprises the front-end device, the streaming media server and the client side browsers. The method and the system provided by theinvention have no need of installing plugins or extensions, support crossing browsers, also have no need of performing related setting operations of the browsers, and can preview no-delay or low-delaymonitoring videos in real time.

Description

technical field [0001] The present invention relates to the fields of video monitoring, security, and the Internet of Things, and more specifically, to a real-time video preview method and system without plug-ins based on the RTSP protocol. Background technique [0002] At present, the video monitoring equipment developed by various video manufacturers needs to install the WEB control provided by the manufacturer when using the browser on the PC to preview the video in real time. On the Internet, users can only choose Microsoft IE browser (based on the ActiveX plug-in) and Chrome kernel browsers of lower versions (before Chrome 42), such as Chrome, Firefox, etc. [0003] And the current problem is that in the prior art, the NPAPI plug-in is disabled from the Chrome 42 version, so that current users can only use the IE browser when viewing real-time video, which limits the user's choice to a large extent, and in In some specific scenarios, when the user cannot use IE, the re...

Problems solved by technology

[0003] And the current problem is that in the prior art, the NPAPI plug-in is disabled from the Chrome 42 version, so that current users can only use the IE browser when viewing real-time video, which limits the user's choice to a large extent, and in In some specific scenarios, when the user cannot use IE, the real-time video of the video device cannot be viewed

[0004] In addition, in many live video solutions of the prior art, the RTMP protocol (Real Time Messaging Protocol, Real Time Message Transmission Protocol) is adopted, which is a network protocol designed to carry out real-time data communication, and is mainly used on the Flash / AIR platform and supports RTMP The audio, video and data communication between streaming media / interactive servers of the protocol is an open protocol developed by Adobe Systems for audio, video and data transmission between Flash players and servers, and FMS (Adobe Flash) is built in the middle Media Server) media server for forwarding, and then through RTMP protocol or HLS protocol (HTTP Live Streaming, which is Apple's dynamic bit rate adaptive technology, mainly used for audio and video services of PC and Apple terminals, including an m3u(8) Index file, TS media segment file and key encrypted string file) are delivered to the client, the former must install Adobe Flash Player to preview in real time, while the video stream delivered by the HLS protocol does not need to install plug-ins, but its real-time performance is poor , the video screen is delayed, which cannot meet the low-latency usage scenarios in the video surveillance and security industries
