Abstract

The invention discloses a video coding method and device, computer equipment and a storage medium, and belongs to the technical field of audios and videos. According to the invention, the current macro block to be coded is the static macro block and the reference video frame is the forward reference P frame, and the coding mode of the static macro block is directly determined as the target codingmode based on the fact that the quality parameter of the static macro block is greater than or equal to the quality parameter of the reference macro block and the motion vector meets the target condition; prediction judgment on other coding modes is skipped, rate-distortion cost does not need to be calculated in an intra-frame mode and an inter-frame mode one by one, and the coding rate can be greatly increased under the condition that coding efficiency is not lost.

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...
