Resolution adjustment method and device

Abstract

The present application provides a resolution adjustment method and device, an electronic device and a storage medium. The method includes: after rendering a picture generated during the running of a cloud application to obtain a rendered picture, encoding the rendered picture, The encoded rendering picture is sent to the terminal, wherein the encoding adopts the target resolution; the target resolution is determined according to the following method: when the detection time arrives and the network state is between poor and good, the current encoding bit rate is obtained; When the encoding bit rate does not meet the first condition and does not meet the second condition, compare the size of the adjustment ratio with the preset downsampling ratio; determine the resolution adjustment scheme according to the result of comparing the size of the adjustment ratio and the preset downsampling ratio, and The target resolution is determined according to the resolution adjustment scheme, and the resolution can be automatically adjusted, thereby improving the fluency and display quality of the cloud application screen.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a resolution adjustment method and device, electronic equipment and a storage medium. Background technique [0002] With the development of cloud technology, more and more cloud applications appear in people's life. The cloud application is based on cloud computing and runs in the virtual machine / container of the cloud server. The virtual machine / container completes all the calculations of the cloud application screen and generates the screen image of each frame, thus forming an image composed of continuous image frames stream, the cloud server sends the image stream to the user terminal, and the user terminal displays each frame of image in sequence. In this mode, the user terminal actually only needs to send the user's operation instructions to the cloud server, and then receive the image stream from the cloud server for playback. [0003] In the field of cloud applications...

Problems solved by technology

When the hardware processing capability and the network bandwidth extreme value are fixed, there are many ways to alleviate problems such as network congestion, jitter, and limited bandwidth. However, using technical means to improve user experience will inevitably cause some other disadvantages, such as production costs. increase (for example, by using additional edge computing nodes to perform super-resolution operations, etc., to send multi-channel data packets to resist packet loss), and image quality deterioration (for example, the use of forward error correction FEC means can be performed without synthesizing the entire data frame at the rendering end. Rendering, there will be loss of color blocks, this method uses incomplete rendering in exchange for the smoothness of the overall picture), etc.
