Abstract

The invention discloses an audio and video synchronization method and device and a mobile terminal. The sound delay time needed when terminal equipment plays an audio through target Bluetooth equipment can be determined; a to-be-played target video and a target audio corresponding to the target video are determined; the target audio starts to be played by the target Bluetooth equipment at the first moment; and the target video starts to be played on the terminal equipment at the second moment, wherein the second moment is later than the first moment, and the time interval between the second moment and the first moment is the sound delay time. Accordingly, synchronous playing of the target video played on the terminal equipment and the target audio which is played on the target Bluetooth equipment and corresponds to the target video can be achieved, the phenomena of mismatching of the lip and the sound, lip-synchronization and the like are avoided, and the good audio-visual experience can be brought to a user.

Description

technical field [0001] The present invention relates to the field of terminals, in particular to an audio and video synchronization method, device and mobile terminal. Background technique [0002] With the rapid development of terminal equipment and Bluetooth audio equipment, there are more and more Bluetooth audio equipment (hereinafter referred to as Bluetooth equipment) that can be connected to terminal equipment. More and more, many users will use these Bluetooth devices to play audio or video on the terminal, which brings great convenience to users' life. [0003] However, when the audio or video on the terminal is played through the Bluetooth device, not only the Bluetooth device requires a certain amount of data processing time, but also the Bluetooth framework (framework) and the Bluetooth driver (driver) on the terminal also require a certain amount of data processing time, which makes the Bluetooth device There is a delay in the sound played. When the Bluetooth ...
