Problems solved by technology

When playing a video with a Dolby audio track on a mobile device, if the speaker is used to play it, the effect of the Dolby audio track is not obvious, but it will take up more hardware resources, affecting the playback startup speed and smoothness of the video, resulting in Bad User Viewing Experience
In addition, if you use headphones to play, you can better feel the realistic sound effect brought by Dolby audio track, but you need to manually turn on the control button of Dolby audio track to enjoy the sound effect, which will also cause bad user viewing experience

Abstract

The invention provides a Dolby audio track control method and device. The method comprises the following steps of: when a video requested to be played is a Dolby audio track-supporting video, judginga current audio play manner of play equipment; if the audio play manner is earphone play, searching whether a closing event record exists or not from a preset path, wherein the closing event record isused for representing that a Dolby audio track has been manually closed during the earphone play; and otherwise, controlling the Dolby audio track to be opened. Through the control method, when a closing event does not exist during the earphone play, the opening of the Dolby audio track can be automatically controlled, and users do not need to manually open the Dolby audio track, so that self-adaptive management of the Dolby audio track is realized, the play performance is optimized and the user experience is enhanced.

Description

technical field [0001] The invention relates to the field of video playback, in particular to a method and device for controlling Dolby audio tracks. Background technique [0002] Dolby Audio is a more advanced high-quality digital audio coding format. Dolby Audio can bring a more realistic sound experience and is widely used in video resources. [0003] At present, Dolby audio tracks are also synthesized in more and more online videos, but because Dolby audio tracks need to carry more information, they require a larger storage space than ordinary audio tracks, and the decoding time is also longer. When playing a video with a Dolby audio track on a mobile device, if the speaker is used to play it, the effect of the Dolby audio track is not obvious, but it will take up more hardware resources, affecting the playback startup speed and smoothness of the video, resulting in Bad user viewing experience. In addition, if you use headphones to play, you can better feel the realist...
