Embodiment Construction

[0046] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0047] In cloud games and cloud computer systems, it is necessary to ensure high image quality, high resolution, high frame rate and low latency. However, because network jitter / blocking is an inevitable phenomenon in the network, this will cause frame drop when displayed on the cloud computer terminal, that is, the picture is not smooth, which will a...

Abstract

The invention discloses a video frame rendering method and device, electronic equipment and a computer readable storage medium, and the method comprises: determining a target length N of a buffer container according to the obtained frame information in a preset time period and the maximum allowed frame drop frequency; when it is detected that the rendering FPS of the displayer is smaller than a preset threshold value and M video frames appear in the vertical synchronization period, rendering the (M-N) th video frame according to the arrival time sequence of all the video frames, and caching the N video frames which arrive lateto a buffer container, wherein M is greater than N; and when each subsequent vertical synchronization period is entered, rendering each video frame in the buffer container according to a first-in first-out principle, and updating the video frames in the buffer container. According to the method, the video frame is not lost, and the relationship between the fluency and the display delay of the picture is balanced, that is, the fluency of the picture is ensured within an acceptable display delay range, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of streaming media, and in particular to a video frame rendering method, device, electronic equipment and computer-readable storage medium. Background technique [0002] With the development of codec technology and software and hardware technology, innovative businesses such as cloud games and cloud computer systems have gradually entered the public's field of vision and achieved certain development. How to ensure high image quality, high resolution, high frame rate, and low latency in cloud games and cloud computer systems is the ultimate optimization goal. As an important link in the cloud computer system, the terminal display strategy has a very significant impact on the actual effect. The fluctuation of RTT (round trip time) is an inevitable phenomenon in the network. A slight jitter will cause the cloud computer to drop frames, resulting in unsmooth images and affecting the user experience. ...
