Abstract

The present application discloses an audio and video playing method, device, device and storage medium, the method comprising: determining the first file start position of the audio data and the second file start position of the video data of the target audio and video; when the When the amount of storable data between the first file start position and the second file start position is greater than or equal to a preset threshold, the audio data and video data are read respectively based on dual IO channels; according to the read audio data sort the read audio data and video data; and play the target audio and video based on the sorted audio data and video data. Utilizing the technical solution provided by this application can solve the problems of low effective data transmission on the network and the inability to synchronize audio data and video data, and ensure the synchronization of audio data and video data during decoding and playback, avoiding the phenomenon of stuttering.

Description

technical field [0001] The present application relates to the field of multimedia technology, and in particular to an audio and video playback method, device, equipment and storage medium. Background technique [0002] With the rapid development of information technology, multimedia technology has become a very important means of communication and information acquisition in people's lives. Audio and video in multimedia provide people with a huge amount of information. Audio and video playback technology as a modern streaming media An important part of playback technology, the quality of its playback effect directly affects the quality of people's ingestion of information, and affects people's subjective feelings. [0003] In the prior art, video data and audio data in audio and video such as mp4 can be interleaved and stored, or can be separated separately and located in different positions of the file. When audio and video are played, for interleaved audio and video, the a...
