Problems solved by technology

This causes the encoding rate of the video encoder to fail to match the network sending rate. When the encoding rate of the video encoder is greater than the network sending rate, the encoded video data will first be stored in the sending buffer queue for buffering. If it continues, It will cause the send buffer queue to buffer a lot of data. After reaching the limit of the send buffer queue buffer, some video data will be discarded

Abstract

The invention provides a video coding rate adjustment method, system and device, and a storage medium. The method comprises the following steps: acquiring a target coding rate of a video encoder; detecting a current coding rate of the video encoder; calculating a rate deviation value between a current coding rate and a target coding rate of the video encoder; obtaining an updated coding rate of the video encoder according to the rate deviation value, and controlling the coding rate of the video encoder based on the updated coding rate. By adopting the method and the device, the video coding rate is updated based on the difference value between the current coding rate and the target coding rate, so the problem that the real-time coding rate of the video coder cannot actually reach the target coding rate is solved, the adaptability between the coding rate of the video coder and the rate of subsequently sending video data is improved, the situation that the sending cache queue caches too much data is avoided, the situation of data packet loss is also avoided, and the accuracy and effectiveness of video data sending are improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a video encoding rate adjustment method, system, device and storage medium. Background technique [0002] In network video transmission, generally, the sending end needs to use a video encoder to perform video encoding first, and then send the encoded video data to the receiving end through the network. The receiving end decodes the video data after receiving it, and then plays it. Network sending sends data to the receiving end at a predicted speed, and the accuracy of this speed can be guaranteed. However, the rate encoded by the video encoder changes continuously with the scene, and generally the encoded rate is greater than the actual bandwidth. This causes the encoding rate of the video encoder to fail to match the network sending rate. When the encoding rate of the video encoder is greater than the network sending rate, the encoded video data will first be...
