The problem that noise exists when the existing audio and video is played is solved, and the user experience is improved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of a method for eliminating video playing noise according to the present invention.
Based on the first embodiment, in this embodiment, after the step S20, the method for eliminating the video playing noise further includes:
step S50: and when the instruction type is a second type instruction, exiting the currently played multimedia file.
It should be noted that the second type of instruction may be an exit current play instruction.
Step S60: and when an application opening instruction is received, determining a corresponding playing application to be opened according to the application opening instruction.
It should be understood that, a plurality of third-party applications, such as certain video playing software, certain audio playing software, and/or other third-party applications, may be installed in the current smart television, and the application starting instruction may be an instruction issued by a user to start one of the third-party applications in the smart television. The to-be-started playing application may be a to-be-started third-party application corresponding to the application starting instruction.
Step S70: and acquiring a preset white list, and judging whether the to-be-started playing application is in the preset white list.
It should be noted that the preset white list may be a list storing packet names of third-party applications with faulty audio during playing in the smart television, for example, if it is known that a problem of no sound occurs during playing of a certain video playing software and a certain audio playing software, the preset white list stores packet names of the certain video playing software and the certain audio playing software, and the determining whether the playing application to be started is in the preset white list may be to obtain the packet name of the playing application to be started, and determine whether the preset white list has the packet name of the playing application to be started.
It should be understood that when a certain product is online or put into production, whether the product has a problem or not can be detected through a self-test or QA test, and whether a third-party application installed on the smart television fails or not can also be detected through the self-test or QA test, so that whether the third-party application has a problem of no sound or not can be found during the self-test or QA test. And when the third-party application is found to have no sound problem, adding the package name of the third-party application having no sound problem into the preset white list.

It should be understood that when the to-be-started playing application is in the preset white list, it can be stated that the playing application has a problem of no sound, and the main reason is that the third-party applications call their own decoding libraries to perform audio/video decoding playing. When playing video and music, the media player service is not called according to the android standard flow, and the Client function executes the release of the Mute action to cause no sound. And most other third party applications play videos, audio and video decoding playing can be carried out according to the android standard flow during music, mediaplayservice is called, Client is called, and the start function executes the action of removing the Mute, so that the sound is normal. When the third-party application does not call mediaplayservice according to the standard flow of android, and the Client performs the Mute release action and causes silence, the second preset function of the multimedia playing service performs the Mute release operation, namely actively calls mediaplayservice, the Client performs the Mute release action and the start performs the Mute release action.
Further, in order to improve the experience of the user and avoid the problem of silence when the third-party application is played, after the steps of obtaining the preset white list and judging whether the playing application to be started is in the preset white list, the method further includes: when the playing application to be started is not in the preset white list, acquiring parameter information of the playing application to be started; judging whether the playing application to be started is in an audio playing state or not according to the parameter information; and when the playing application to be started is not in the audio playing state, executing mute release operation through a second preset function of the multimedia playing service.
It should be noted that the parameter information may be audio/video decoding information of the to-be-started playing application, for example, whether mediaplayservice is called according to an android standard flow, Client:: a start function performs a Mute release action, or parameter information detecting whether the to-be-started playing application has sound after being started, judging whether the to-be-started playing application is in an audio playing state according to the parameter information may be judging whether the to-be-started playing application calls mediaplayservice according to the android standard flow according to the audio/video decoding information of the to-be-started playing application, Client:: a start function performs a Mute release action, when the to-be-started playing application does not call mediaplayservice according to the android standard flow, Client:: a start function performs a Mute release action, it is determined that the to-be-started playing application is not in the audio playing state, at this time, a Mute release operation is performed through a second preset function of the multimedia playing service, namely, actively calling mediaplayervice:: Client:: start function to execute the action of releasing the Mute.
Further, in order to save the processing flow when the third-party application is switched next time, after the step of determining whether the playback application to be started is in the audio playback state according to the parameter information, the method further includes: and when the playing application to be started is not in the audio playing state, adding the playing application to be started into the preset white list.
Further, in order to improve the experience of the user, the step of acquiring a preset white list and determining whether the to-be-started playing application is in the preset white list specifically includes: acquiring a current network state, and judging whether the current network state is in a networking state or not; when the target server is in a networking state, downloading a white list file from the target server, and taking the white list file as the preset white list; and acquiring an application identifier of the playing application to be started, and judging whether the playing application to be started is in the preset white list according to the application identifier.
It should be noted that, the obtaining of the current network state may be obtaining a network state of a local area network in which the smart television is currently located, the target server may be a server for performing data sharing or managing the smart television, the white list file may be a file storing a flag of a third-party application that has no sound problem, and the application identifier may be a package name of the third-party application or an identifier that can uniquely represent the third-party application, which is not limited in this embodiment.
It should be understood that after downloading the white list file from the target server, in order to avoid the problem that the white list file cannot be acquired due to no networking state later, the smart television stores the white list file, so that the current latest white list file can be used even when the white list file is in a non-networking state later.
It should be understood that when a silent problem occurs in a certain third-party application on one smart television, other smart televisions also occur, and at this time, the identifier of the third-party application having the silent problem needs to be uploaded to the server, so that a large number of smart television users can share data, and user experience is improved.
In this embodiment, when the instruction type is the second type of instruction, exiting the currently played multimedia file; when an application opening instruction is received, determining a corresponding playing application to be opened according to the application opening instruction; acquiring a preset white list, and judging whether the to-be-started playing application is in the preset white list or not; and when the playing application to be started is in the preset white list, executing mute release operation through a second preset function of the multimedia playing service.
