Audio data processing method, device, electronic device and storage medium

Abstract

The present invention provides an audio data processing method, device, electronic equipment, and storage medium, the method comprising: reading audio data from a cache module; determining whether the audio data is audio data whose time stamp needs to be corrected; The first function module reads a first parameter, and the first parameter is used to indicate the initial time stamp of the audio data; according to the initial time stamp of the audio data, the time stamp of the audio data is corrected to obtain the Corrected timestamp of the above audio data. The invention can correct the time stamp of the audio data to realize the synchronization of audio and video.

Description

technical field [0001] The present invention relates to the technical field of audio data processing, in particular to an audio data processing method, device, electronic equipment and storage medium. Background technique [0002] The smart terminal can realize the function of playing audio and video files, wherein, the multimedia synchronization function in the smart terminal is to allow the multimedia data with the same timestamp (presentationtimestamp, pts) in multiple multimedia data such as video data and audio data to be downloaded at the same time Play out, that is to achieve audio and video synchronization. [0003] Gstreamer is currently a common open source multimedia framework for multimedia synchronization. It uses the Gstaudioringbuffer module to buffer audio data, and provides a clock for audio data transmission to achieve audio and video synchronization control. In order to reduce the transitional consumption of the overall machine performance when transmitti...

Problems solved by technology

[0004] However, in this audio and video playback mode, when the user switches the audio and video track (such as switching from Chinese to English) to play the audio and video on the smart terminal, the Gstaudioringbuffer module needs to be destroyed and rebuilt, and the cached audio data If the Gstaudioflingersink module directly calculates the time stamp based on the parameters of the reconstructed audio data in the Gstaudioringbuffer module, there will be an error between the time stamp and the time stamp of the audio data before switching tracks, which will cause the audio and video to be out of sync.
