Problems solved by technology

[0002] With the development of network technology, watching audio and video through the network has gradually become the mainstream. However, for users with poor networks, audio and video are prone to frame discarding during transmission, and then black screens, freezes and other playback abnormalities occur.

Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0034] Existing mainstream video coding algorithms, such as H.264 / H.265 / H.266 / AVI (Audio Video Interleaved, audio video interleaved format) / VP9, etc., the default video coding GOP (group of pictures) sequence (I / P / B frame) will provide references for other types of frames in the sequence. The mutual reference between frames improves the coding compression efficiency. A frame only needs to save the difference between itself and the referenced frame, but the mutual reference mode will lead to...

Abstract

The embodiment of the invention discloses a data transmission method and device, electronic equipment and a storage medium. The method comprises the steps that audio and video coding data to be transmitted are acquired, the audio and video coding data to be transmitted comprise M video frame layers and audio frame layers, each video frame layer and each audio frame layer have corresponding level serial numbers, the video frame layer with the high level serial number depends on the video frame layer with the low level serial number to conduct decoding, the level sequence number of the audio frame layer is lower than the level sequence number of any video frame layer; a current network state of the target network is obtained; a target frame layer corresponding to the current network state is determined, wherein the target frame layer comprises an audio frame layer and N video frame layers of which the level serial numbers are arranged step by step from the lowest level to the higher level; and the data corresponding to the target frame layer is sent to the target terminal through the target network. According to the method, the condition of network congestion can be relieved while normal decoding and video watching image quality of the target terminal are ensured, so that the abnormal condition of video playing of the target terminal is relieved.

Description

technical field [0001] The present application relates to the field of computer technology, and more specifically, to a data transmission method, device, electronic equipment, and storage medium. Background technique [0002] With the development of network technology, watching audio and video through the network has gradually become the mainstream. However, for users with poor networks, audio and video are prone to frame discarding during transmission, and then black screens, freezes and other playback abnormalities occur. . Contents of the invention [0003] In view of the above problems, embodiments of the present application propose a data transmission method, device, electronic device, and storage medium to improve the above problems. [0004] In the first aspect, the embodiment of the present application provides a data transmission method, the method includes: obtaining audio and video coding data to be transmitted, the audio and video coding data to be transmitted...
