Problems solved by technology
[0003] The existing web video playback protocols mainly include rtmp, hls, http-flv, etc. The rtmp protocol depends on the flash plug-in, which is currently limited in browsers such as Google, and the protocol interaction is relatively complicated, which requires certain technical requirements for server developers; hls is limited by the protocol itself, it is difficult to reduce the delay to less than two seconds, and it cannot be used in live broadcast scenarios that require low delay; http-flv technology currently also has high delay (1000-2000 milliseconds), and the page is minimized. It is easy to cause problems such as live broadcast suspension

The technical field of webpage playback of the present invention relates to a websocket-based flv video transmission and webpage playback method, including the following steps: receiving the video source client of the server, and decapsulating the video obtained by using the decapsulation module Encapsulate the video h264 naked stream; repackage the video h264 naked stream into flv standard format video through the encapsulation conversion module; cache the obtained MetaData package in memory; the WebSocket client sends a request command to establish a connection with the websocket, and follow the complete flv standard format video to push video data; detect the sending status of the MetaData package to determine whether the MetaData package has been sent; after the MetaData package has been sent, the ordinary audio and video data package is sent; use the webpage decoding plug-in for the received push data Do decoding and rendering operations and play. The advantage is that not only the video can be played without relying on the flash plug-in, but also the video can be played with a lower delay.
Description
technical field [0001] The invention belongs to the technical field of webpage playing, and relates to a method for websocket-based flv video transmission and webpage playing. Background technique [0002] With the development of Internet technology and web technology, web video live broadcast technology is more and more widely used in interactive live broadcast, security, remote operation and other scenarios. [0003] The existing web video playback protocols mainly include rtmp, hls, http-flv, etc. The rtmp protocol depends on the flash plug-in, which is currently limited in browsers such as Google, and the protocol interaction is relatively complicated, which requires certain technical requirements for server developers; hls is limited by the protocol itself, it is difficult to reduce the delay to less than two seconds, and it cannot be used in live broadcast scenarios that require low delay; http-flv technology currently also has high delay (1000-2000 milliseconds), and ...
