Abstract

The invention discloses a method for improving video rendering efficiency and user interaction fluency. The method comprises the steps that 1, initializing a video rendering module and entering a dormant state; 2, awakening a rendering module by an external triggering event; 3, performing event processing by the rendering module, and three kinds of events exist; 4, entering a vertical synchronization state, if the distance between the current timestamp and the last rendering start time is greater than 1/60 seconds, directly executing the next step, otherwise, if the current timestamp is a dataevent, carrying out frame loss operation, and if the current timestamp is a UI event, entering a timing queue, and rendering at a time point greater than or equal to a vertical synchronization interval; and 5, entering a rendering state, binding the current frame with the graph api according to the internal parameters, and then calling the graph api for rendering. According to the method, excellent balance between video playing fluency and rendering efficiency is achieved, and efficient video rendering can be achieved.

Description

technical field [0001] The invention relates to the technical field of computer software, in particular to a method for improving video rendering efficiency and user interaction fluency. Background technique [0002] Video rendering is a technology to display the decoded original video data. There are two common video rendering processes: [0003] One is to directly render the image data. Because the refresh rate of rendering is related to the frame rate of the video, the disadvantage of this method is that if you encounter a video with a low frame rate (less than 60 frames per second), you will need to perform UI operations (zoom in, zoom out) , rotation, animation, etc.), there will be a freeze; [0004] The other is to poll at a fixed frequency to fetch image data for rendering. Although this method can make the UI operation smoother, it also has disadvantages. The main reason is that when the UI operation is not triggered, the polling frequency is often greater than Th...
