Abstract

The embodiment of the invention provides a video coding rate determination method and device, equipment and a storage medium. The method comprises the steps that the frame type of a current frame to be coded of a video to be coded is determined, and the frame type is an interested frame or a non-interested frame; according to the frame type of the current to-be-coded frame, the pre-coding code rate of the current to-be-coded frame is adjusted to obtain a target coding code rate of the current to-be-coded frame; wherein if the frame type is an interested frame, the precoding code rate of the current to-be-coded frame is improved, and if the frame type is a non-interested frame, the precoding code rate of the current to-be-coded frame is reduced. In the embodiment of the invention, when a video to be encoded is encoded, a human eye vision theory can be combined with video encoding for each frame to be encoded, so that the subjective quality of the encoded video can be improved under thecondition of low encoding rate, and the subjective quality of the video can be guaranteed and the encoding rate can be saved under the condition of high encoding rate.

Description

Technical field [0001] The present invention relates to the technical field of image processing. Specifically, the present invention relates to a method, device, device, and storage medium for determining a video coding rate. Background technique [0002] The video needs to be encoded during the video transmission process. In the prior art, in the process of encoding a video, all frames of the video are usually grouped, and the same strategy is adopted for each frame in the group, based on the remaining bit rate in the current group and the number of frames in the group. To dynamically adjust the coding rate assigned to each frame, and control the coding rate to a certain size to ensure the coding 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 within the frame, resulting in a relatively low subjective quality of the encoded video under the c...
