Problems solved by technology

At present, various compression coding technologies have become more and more perfect and mature, and the compression efficiency has reached a high level, so it is difficult to greatly improve the compression ratio.
In video coding, the method of simply relying on increasing quantization parameters to reduce the bit rate will inevitably affect the subjective quality of coding.

Abstract

The embodiment of the invention relates to the technical field of video processing, and discloses a video coding method and device, electronic equipment and a computer readable storage medium, and the video coding method comprises the steps: analyzing and processing a video frame in a to-be-coded video, and determining a first region of interest of the video frame; performing coding preprocessing on the video frame, and determining a first quantization parameter value of the video frame; adjusting the first quantization parameter value based on the first region of interest to obtain a second quantization parameter value for the video frame; and then carrying out quantization coding on the video frame after coding preprocessing according to the second quantization parameter value for the video frame. According to the method provided by the embodiment of the invention, the code rate in any video frame can be dynamically adjusted according to the region of interest of any video frame, so that the video watching experience is greatly improved, and particularly, in a low-code-rate scene, the video watching effect of a watcher is effectively improved.

Description

technical field [0001] Embodiments of the present application relate to the technical field of video processing, and specifically, the present application relates to a video encoding method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] In recent years, with the rapid development of multimedia and network technology, video processing technology has been applied to a wider field, which also puts forward more new requirements for video processing technology. The amount of video data is often very large. In order to effectively transmit and store video, it is necessary to effectively compress the video data. At present, various compression coding technologies have become more and more perfect and mature, and the compression efficiency has reached a high level, so it is difficult to greatly improve the compression ratio. In video coding, the method of simply increasing the quantization parameter to reduce the bit rate will ine...
