Abstract

The application discloses a video encoding method, device, computer equipment and storage medium, belonging to the technical field of audio and video. In this application, the current macroblock to be encoded is a static macroblock and the reference video frame is a forward reference P frame, based on the quality parameter of the static macroblock being greater than or equal to the quality parameter of the reference macroblock and the motion vector meeting the target condition, the static The coding mode of the macroblock is determined as the target coding mode, skipping the prediction and judgment of other coding modes, and there is no need to calculate the rate-distortion cost of intra-frame mode and inter-frame mode one by one, which can greatly improve the coding rate without losing coding efficiency .

Description

technical field [0001] The present application relates to the field of audio and video technologies, and in particular to a video encoding method, device, computer equipment and storage medium. Background technique [0002] With the development of audio and video technology and the diversification of terminal functions, users can watch videos anytime and anywhere through the terminal. When the server transmits the video to the terminal, it needs to compress (that is, encode) the video to save communication overhead. In the coding process, it is necessary to divide the video image into multiple blocks, and make a coding mode decision for each block, and select the optimal coding mode. The decision-making process of the above-mentioned coding modes is cumbersome, so there is an urgent need for a way to increase the coding rate without losing coding efficiency. Contents of the invention [0003] Embodiments of the present application provide a video coding method, device, c...
