Abstract

The invention discloses a page video rendering method and device. The method comprises the following steps that: a main thread creates at least one sub-thread, and when a page video is played and themain thread receives video original code streams of a plurality of video windows, the main thread calls the sub-thread to respectively carry out video decoding on the video original code stream of each video window so as to obtain image data of each video window; and then, the main thread receives the image data of each video window called back by the sub-thread, and when the page is refreshed, the main thread merges the image data of the plurality of video windows and submits the merged image data to a graphics processor. Furthermore, the main thread merges and submits a drawing instruction to the graphics processor based on the image data of the plurality of video windows. According to the technical scheme, the video decoding process is allocated to the sub-threads, so that the utilization rate of the multi-core CPU is improved, and the operation time consumption and the system overhead under the multi-video window are reduced by combining the submitted image data and the combined drawing instruction.

Description

【Technical field】 [0001] The present invention relates to the technical field of webpage video rendering, in particular to a webpage video rendering method and device. 【Background technique】 [0002] Web Graphics Library (WebGL for short) is a 3D drawing protocol. This drawing technology standard allows the combination of JavaScript and OpenGL ES 2.0. By adding a JavaScript binding of OpenGL ES 2.0, WebGL can be used as HTML5 Canvas Provide hardware 3D accelerated rendering, so that web developers can display 3D scenes and models more smoothly in the browser with the help of system graphics cards, and can also create complex navigation and data visualization. It can be seen that the WebGL technical standard eliminates the trouble of developing a special rendering plug-in for web pages, and can be used to create website pages with complex 3D structures, and can even be used to design 3D web games. [0003] Figure 1A It is a schematic diagram of signaling sequence of a page ...
