Abstract

Embodiments of the present invention provide a video coding rate determination method, device, equipment and storage medium. The method includes determining the frame type of the current frame to be encoded of the video to be encoded, wherein the frame type is a frame of interest or a non-interesting frame; according to the frame type of the current frame to be encoded, the precoding code rate of the current frame to be encoded is performed Adjust to obtain the target encoding bit rate of the current frame to be encoded; among them, if the frame type is a frame of interest, then increase the precoding bit rate of the current frame to be encoded, and if the frame type is a non-interesting frame, then reduce the current frame to be encoded precoding bit rate. In the embodiment of the present invention, when encoding the video to be encoded, the human vision theory can be combined with video encoding for each frame to be encoded, which can ensure that the subjective quality of the encoded video is improved under the condition of low encoding bit rate. Quality, and under the condition of high bit rate, it can guarantee the subjective quality of the video and save the encoding bit rate.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular, the present invention relates to a method, device, device and storage medium for determining a coding rate of a video. Background technique [0002] Video needs to be encoded during video transmission. In the prior art, in the process of video encoding, all the frames of the video are usually grouped, and the same strategy is used for each frame in the group, based on the remaining code rate in the current group and the number of frames in the frame. The complexity to dynamically adjust the encoding rate assigned to each frame, and control the encoding rate to a certain size to ensure the encoding quality of the video. [0003] However, this solution does not take into account the characteristics of human vision. The human eye pays different attention to each frame and each position in the frame, which leads to poor subjective quality of encoded video under lo...
