A method for supporting browsers to play videos in any encoding format

Abstract

The invention relates to a method for supporting a browser to play a video in any encoding format, which includes the communication connection between a browser and a streaming media server, and obtaining the IP and port of audio and video streams sent by the streaming media server; The background service sends the IP and port of the audio and video streams to the local background service through an interactive protocol; the streaming media server communicates with the local background service, and sends the audio and video streams directly to the local background service. Local background service; the local background service decodes the audio and video streams, and sends the decoded video stream data to the browser; the browser completes the video playback operation; the decoded audio Streaming data is played directly by the computer. By adopting the technical scheme of the present invention, not only can the video files of all encoding formats be decoded, but also the decoding efficiency is high, and the decoding can be completed synchronously for files with large video resolution.

Description

technical field [0001] The invention relates to the technical field of computer Internet, and in particular, to a method for supporting a browser to play videos in any encoding format. Background technique [0002] At present, in the security field, there are a variety of video encoding formats. For example, videos in mpeg2 and mpeg4 formats supported and shot by some old cameras are still widely available in the market. At the same time, there are some new videos in H.265 encoding format. . However, the video tag in the HTML5 standard defined by major browser manufacturers and W3C cannot decode these video formats. As a result, in the scenario where the browser is used as the client, these video streams need to be transcoded. During the transcoding process It will waste a lot of computing resources of the background server. [0003] In response to this problem, the current mainstream technology is that a streaming media server communicates directly with a browser, and the...

Problems solved by technology

Everyone generally uses WebAssembly technology to compile ffmpeg into a javascript script interface, directly call decoding in the browser, and continuously display video frames as pictures in the browser, but because WebAssembly technology removes assembly language when editing ffmpeg, it is more efficient Advantages, resulting in low decoding efficiency, especially when the video resolution is greater than 1920×1080, there will be obvious delays

There are also some manufacturers using browser plug-ins to decode and display videos in the plug-ins, but as major browsers no longer support plug-ins, the browser plug-ins cannot be used
