Data transmission method, device, electronic device and storage medium

Abstract

The embodiments of the present application disclose a data transmission method, an apparatus, an electronic device, and a storage medium. The method includes: acquiring audio and video encoded data to be transmitted, the audio and video encoded data to be transmitted including M layers of video frame layers and audio frame layers, each layer of video frame layers and audio frame layers has a corresponding layer sequence number, and the video frame with a higher layer sequence number The layer depends on the video frame layer with the lower layer sequence number for decoding, and the layer sequence number of the audio frame layer is lower than that of any video frame layer; obtains the current network state of the target network; determines the target frame layer corresponding to the current network state, the target frame layer It includes the audio frame layer and the N-layer video frame layer whose hierarchical sequence numbers are arranged from the lowest layer to the upper layer; the data corresponding to the target frame layer is sent to the target terminal through the target network. The method can alleviate the network congestion while ensuring the target terminal can decode normally and the video viewing quality, thereby alleviating the abnormal situation of video playback of the target terminal.

Description

technical field [0001] The present application relates to the field of computer technology, and more particularly, to a data transmission method, apparatus, electronic device, and storage medium. Background technique [0002] With the development of network technology, watching audio and video through the Internet has gradually become the mainstream. However, for users with poor network, audio and video are prone to frame drop during the transmission process, resulting in abnormal playback such as black screen and freeze. . SUMMARY OF THE INVENTION [0003] In view of the above problems, the embodiments of the present application propose a data transmission method, apparatus, electronic device, and storage medium to improve the above problems. [0004] In a first aspect, an embodiment of the present application provides a data transmission method, the method includes: acquiring encoded audio and video data to be transmitted, the encoded audio and video data to be transmit...
