Abstract

The invention discloses a code rate control method, electronic equipment and a computer readable storage medium. The method comprises the following steps: acquiring a target bit of a to-be-coded frame, wherein the to-be-coded frame comprises a plurality of macro blocks; determining a target code rate level of a to-be-coded video sequence to which the to-be-coded frame belongs; determining first weights of the plurality of macro blocks based on the target code rate level; distributing a target bit of the to-be-coded frame to a plurality of macro blocks according to the first weight; and calculating quantization parameters of the plurality of macroblocks based on the target bits allocated for the plurality of macroblocks. Through the above mode, the adaptation degree of the target bit distribution mode of the macro block and the user demand can be improved.

Description

technical field [0001] The present application relates to the technical field of video coding, and in particular to a code rate control method, electronic equipment, and a computer-readable storage medium. Background technique [0002] Video codec standards include H.264 / AVC, H.265 / HEVC, H.266 / VVC, VP8, VP9, ​​AV1, AVS, etc. The main purpose is to compress the collected video signals into data in different standard formats , for easy transport or storage. In order to apply video coding technology to actual scenarios, bit rate control technology plays a vital role in video encoders, because it can adjust the target bit rate of the encoder output under the condition of limited communication bandwidth or storage space, This prevents the encoded video frame from being too large or too small. [0003] The code rate control technology sequentially allocates the video signal at the group of picture level, frame level and macroblock level, and obtains the target bits at the group ...
