Code rate control method and device for audio and video transmission, equipment and storage medium

Abstract

The embodiment of the invention discloses a code rate control method and device for audio and video transmission, equipment and a storage medium. The method comprises the following steps: receiving playing condition information fed back by a client, wherein the playing condition information comprises to-be-played duration corresponding to audio and video data which are received and not played by the client and a timestamp of a last playing frame, estimating the receiving code rate of the client according to the playing condition information, determining sending condition information of the audio and video data, and determining a code rate control mode of the audio and video data transmission according to the playing condition information and the receiving code rate and the sending condition information of the client. According to the technical scheme provided by the embodiment of the invention, comprehensive evaluation is carried out by referring to information of multiple dimensions, the code rate of audio and video transmission can be more reasonably controlled, and the audio and video playing fluency and the audio and video playing quality are better considered.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of code rate control for audio and video transmission, and in particular, to a code rate control method, device, device, and storage medium for audio and video transmission. Background technique [0002] With the continuous development of multimedia information technology, a large number of audio and video information emerge. As a comprehensive medium for expressing information, audio and video have become an important information carrier in real life. [0003] Audio and video data usually contains a large amount of image and sound information. In some application scenarios, it is usually necessary to encode audio and video data during audio and video transmission. However, due to differences in network conditions in actual scenarios, in order to take into account audio and video For the smoothness of playback and the quality of audio and video playback, the bit rate of different gears...

Problems solved by technology

In the prior art, the decision-making method of bit rate switching is usually based on the bandwidth method, which switches to the corresponding bit rate according to the network bandwidth detected by the congestion control algorithm used when sending audio and video data. However, in a complex and changeable network environment , it is very difficult to detect accurate bandwidth only through congestion control algorithms, and inaccurate bandwidth estimation will lead to poor performance of such methods

[0006] In summary, the current code rate control scheme for audio and video transmission is still not perfect and needs to be improved
