A kind of audio and video synchronization method and electronic equipment

Abstract

Embodiments of the present invention provide an audio and video synchronization method and electronic equipment, which relate to the technical field of electronic information, and can reduce video jitter generated during video playback and improve video playback quality. The method is: obtain the time stamp of the audio data played by the audio playback module of the media content and the time of the system clock, and then obtain the deviation value between the time stamp of the audio data and the time of the system clock, and make the deviation value and the preset time threshold Compare, determine whether to synchronize the system clock time to the time stamp of the audio data according to the comparison result, if the system clock time is synchronized to the time stamp of the audio data, then obtain the time corresponding to the time of the system clock according to the time of the system clock after synchronization Video data, so that the video playback module continues to play the media content from the video data corresponding to the time after the system clock is synchronized. The embodiment of the present invention is used for synchronizing audio data and video data of media content.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to an audio and video synchronization method and electronic equipment. Background technique [0002] In the original Android (Android) ecosystem, the synchronization principle of video file playback is that when the video is playing, the video playback module obtains the timestamp when the audio playback module is playing audio data, and then obtains the timestamp of the audio data and the time stamp of each frame of the video. If the error is within the allowable range, the frame of video will be played. If the error is outside the allowable range, and the time stamp of the video frame is later than the time stamp of the audio data, the video frame will be discarded. If the video If the time stamp of the frame is earlier than the time stamp of the audio data, the video frame is played when the time stamp of the video frame and the time stamp of the audio data are syn...
