Problems solved by technology

[0003] Under the condition of limited bandwidth, traditional encoders encode video frames indiscriminately, which may cause poor video quality in some scenes. For example, at 750kbps, when encoding all video frames indiscriminately, there are some In the case of poor video frame quality, for example, encoders based on H.264\H.265\iOS have similar problems

Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] figure 1 It is an application scene diagram of a video encoding or video decoding method in an embodiment. refer to figure 1 , the application scenario includes the terminal 110 and the server 120.

[0044] The video encoding method and the video decoding method can be completed in the terminal 110 or the server 120. The terminal 110 can encode the input video frame using the video encoding method and then send the encoded data to the server 120, or receive the encoded data from the server 120 for decoding. Generate decoded video frames. The server 120 can encode the video frame. At this...

Abstract

The invention relates to a video coding method and device, a video decoding method and device and computer equipment. The video coding method comprises the following steps of acquiring a video frame to be coded; determining a resolution determining mode of a current reference frame corresponding to the video frame to be coded according to a resolution relation between the video frame to be coded and a corresponding reference frame; generating a current reference frame corresponding to the video frame to be coded according to the resolution determining mode; coding the video frame to be coded according to the current reference frame in order to obtain coding data corresponding to the video frame to be coded, wherein the coding data comprises identification information representing the resolution relation. According to the scheme, the current reference frame matched with the resolution is flexibly selected, and the coding accuracy is improved, so that the coding quality of the video frame is improved.

Description

technical field [0001] The present invention relates to the field of video coding, in particular to video coding and decoding methods, devices, computer equipment and storage media. Background technique [0002] With the development of digital media technology and computer technology, video is used in various fields, such as mobile communication, network monitoring, network TV and so on. With the improvement of hardware performance and screen resolution, users' demand for high-definition video is increasingly strong. [0003] Under the condition of limited bandwidth, traditional encoders encode video frames indiscriminately, which may cause poor video quality in some scenes. For example, at 750kbps, when encoding all video frames indiscriminately, there are some In the case of poor video frame quality, for example, encoders based on H.264\H.265\iOS have similar problems. Contents of the invention [0004] Embodiments of the present invention provide a video encoding and ...
