Abstract

The invention provides a stable frame rate video data generation method and device, equipment and a storage medium. The method comprises the steps: determining a mode in which a system obtains collected video data; if the system obtains the collected video data through a callback interface, presetting a cache used for storing only one frame of video picture before the video data are collected; when the picture of the collected video data changes, calling back to obtain the collected latest frame of video picture and storing the collected latest frame of video picture in the cache; and when the video data is generated, starting a thread, and acquiring the video frames required by the video data from the cache at a fixed time interval. According to the stable frame rate video data generation method, when the video data is obtained through the callback interface, the frame of video picture obtained through callback is stored in the special cache to be obtained by the thread for generating the video data, so that stable and continuous video frames can be obtained, and a video playing effect is better.

Description

technical field [0001] The present invention relates to the technical field of screen projection, and in particular to a method, device, equipment and storage medium for generating video data with a stable frame rate. Background technique [0002] At present, in screen projection, the source of video data is mainly camera collection and device desktop data collection, etc. Different system platforms provide different collection methods, some of which are through callback interfaces and generally only when video data changes. Provide an interface for users to actively call to obtain video data collected by the camera and desktop snapshot data, which results in different video frame rates obtained by users on different devices, and unstable frame rate collection will affect the subsequent video display effect. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The main purpose of the present invention is to solve t...
