System and method for expanding and playing RTSP video by calling OCX of VLC player through BS architecture

Abstract

The invention discloses a system and a method for expanding and playing RTSP (Real Time Streaming Protocol) videos by calling a VLC (Visual Link Control) player OCX (Open Cascading Exchange) through a BS (Browser / Server) architecture, belongs to the technical field of playing RTSP video streams through browsers, and aims to solve the technical problem of how to realize low-delay and multi-path stable playing effects of the RTSP video streams in modern multiple browsers without depending on transcoding and proxy servers. According to the technical scheme, the system comprises a browser front-end unit, a service process unit, a VCL player and an installation engine unit, the VLC player is embedded in a page of the browser front-end unit, and a VLC player OCX extension unit is installed in the VLC player; the service process unit is installed on the local computer, and the browser front-end unit is connected with the service process unit.

Description

technical field [0001] The invention relates to the technical field of playing RTSP video streams through a browser, in particular to a system and method for BS architecture to call VLC player OCX to expand and play RTSP videos. Background technique [0002] A browser is an application program used to retrieve, display and deliver web information resources. A Web information resource is marked by a Uniform Resource Identifier (Uniform Resource Identifier, URI), which is a web page, a picture, a video, or any content presented on the Web. Users can use hyperlinks (Hyperlinks) to browse interrelated information through a browser. [0003] VLC player is a free and open source cross-platform multimedia player and framework, which can play most multimedia files, as well as DVD, audio CD, VCD, RTSPH.245 and H.246 and various streaming media protocols. And VLC player provides OCX extension and detailed interface, which can be called by external programs. [0004] In order to pla...

AI Technical Summary

Problems solved by technology

Since FlashPlayer has been offline, the use of FlashPlayer has expired, and a transcoding server needs to be built during the implementation process. When multi-browser clients play multiple channels, the pressure is concentrated on the decoding server, there is a screen delay, and distributed clients cannot be used. PC realizes hardware acceleration and rendering playback

[0006] ②. Build a WebSocket proxy video forwarding server. The forwarding server continuously pushes the RTSP video stream to the JavaScript processing library of the client browser through the WebSocket protocol. The browser converts the pushed video stream into the MP4 format supported by Video through JavaScript and then plays it. , the implementation process needs to build a WebSocket proxy server, the pressure is concentrated, and it runs in the browser sandbox, which cannot make full use of the client PC hardware acceleration to achieve decoding, rendering and playback

Due to the segmented push through WebSocket, there will also be a delay in the display of the first screen

[0007] ③. Call the VLC player OCX extension through IE Active or ChromeNPAPI to realize the playback of RTSP video streams in the browser. It is suitable for browsers with versions below IE and Chrome 45, but Chrome 2015 disabled NPAPI, so Chrome NPAPI The extension is invalid, so only IE browser is supported, and IE may not be supported by Microsoft in the future

[0008] ④. The Chrome browser uses the IE kernel by installing the IETab (provided by Blackfish Software, LLC. manufacturer) plug-in, and then calls the VLC player OCX extension through ActiveX to realize the playback of RTSP video streams in IE and Chrome browsers; the follow-up demand is uncontrollable , relying heavily on IE's ActiveX, future Chrome upgrades and IE upgrades will have a greater risk for this solution, and it will not be compatible with other browsers such as Firefox
