Problems solved by technology

[0005] For the second special playback requirement, existing multimedia players cannot perceive the user’s special playback requirement, and will continue to play video and audio, but in this case, since the user only needs to hear the sound, the played video is Useless work, which obviously consumes a lot of power from the device
In addition, when the device is in power saving mode, the screen of the device is generally turned off, and the multimedia player will be suspended when the screen is turned off, which will make it impossible to continue playing audio and video in power saving mode
[0006] It can be seen that the existing multimedia players cannot meet the personalized needs of users. When the screen of the device is turned off, only the sound is played but not the video.

Abstract

The invention provides an audio and video play method and a multimedia player. The method comprises following steps that: a screen detection module determines the current state of a device screen according to a set rule; a current screen state obtaining request sent by a multi-way splitter is received; the current state of the screen is sent to the multi-way splitter in response to the request; when the current state of the screen is a closed state, the multi-way splitter applies to an operation system for a background working authority so that the audio code stream is decoded on the background; the multi-way splitter only sends the split audio code stream to an audio decoder for decoding, thus only playing the audio. Through the audio and video play scheme provided by the invention, the individual demands of users can be satisfied; and when the device screen is closed, the sound is played while the video is not played.

Description

technical field [0001] The invention relates to the technical field of audio and video processing, in particular to an audio and video playing method and a multimedia player. Background technique [0002] At present, users mainly play audio and video data through a multimedia player to obtain a dual viewing experience in both auditory and visual senses. However, when watching movies, users often have some special playback requirements. [0003] The first special playback requirement is: the user only wants to see the video, but does not want to hear the sound, such as: suddenly there is a phone call or needs to receive other sounds, then the user will have the above-mentioned special playback requirement. Existing multimedia players can generally provide a mute function. When users have the above-mentioned special needs, they can shield the sound by turning on the mute function of the multimedia player. When users need to hear the sound, they can play the multimedia by turn...
