Abstract

An audio and video playing synchronization method, and an audio and video playing synchronization device. The method comprises: when audio of a multimedia file is played via an external sound device, acquiring device information about the external sound device; searching a pre-set database according to the device information, and determining a delay time when the external sound device plays the audio, wherein the pre-set database contains a correlation between the device information and the delay time; and adjusting a video of the multimedia file according to the delay time to enable the audio and the video to be played synchronously. The purpose of automatically adjusting audio and a video picture for synchronization when the audio of a multimedia file is played via an external sound device is realized.

Description

technical field [0001] The invention relates to the technical field of computer multimedia, in particular to a method and a device for synchronously playing audio and video. Background technique [0002] With the development of computer multimedia technology, people often play multimedia files such as audio or video on computers, mobile phones and other equipment in daily life. However, when users connect an external sound device, they often find that the sound is not synchronized with the video. For example, after the character in the video finishes speaking, the external sound device plays the voice of the character in the video. The sound delay caused by the external sound device Make the user experience poor. [0003] In the prior art, the playback device can allow the user to adjust according to the delay of the external sound playback device, so that the playback sound is synchronized with the video. In this case, users often manually adjust and confirm step by step ...
