Abstract

The invention discloses a coding method and device, electronic equipment and a computer readable storage medium. The coding method comprises: judging whether the resolution of a screen capture image is larger than a preset resolution threshold value or not; if not, up-sampling the screen capture image to a preset multiple by using an up-sampling algorithm, and converting the up-sampled screen capture image into a YUV420 format; if yes, switching the screen capture image to a YUV444 format or a YUV420 format according to a dynamic switching strategy; and performing YUV420 coding or YUV444 coding on the screen capture image by using a YUV420 format or a YUV444 format. According to the method, the YUV444 format or the YUV420 format suitable for the screen capture image, namely the screen content, is used for encoding, the definition of the image is improved, the phenomenon that the image quality is blurred due to the fact that the encoding effect on the screen content of the screen capture image is poor in the related technology is avoided, and the overall performance of the image is improved to the maximum extent.

Description

technical field

[0001] The present invention relates to the field of communication technology, in particular to an encoding method, device, electronic equipment and computer-readable storage medium. Background technique

[0002] With the development of codec technology and software and hardware technology, more services such as cloud games and cloud computer systems have been applied. The video in the cloud game system comes from the desktop video captured on the host side, which belongs to the screen content. Compared with the video captured by the traditional camera, it is very different. Screen content videos are images generated by electronic devices, generally including computer graphic text, hybrid images combining natural images and graphic text, and computer-generated animations. The images collected by the camera usually contain the noise of the sensor, and the color tone is generally continuous and the texture is complex. The screen content image does not contain...
