Example one
Fig. 1 is a flowchart of a vehicle audio playing control method according to an embodiment of the present invention, where the present embodiment is applicable to a situation where audio applications of multiple operating systems in an automobile cabin play audio, and the method may be executed by a vehicle audio playing control device according to an embodiment of the present invention, where the device may be implemented in a software and/or hardware manner, as shown in fig. 1, the method specifically includes the following steps:
s110, if an audio focus application request of a target audio application in any vehicle-mounted operating system is received through the audio focus service, determining the associated audio application to which the audio focus currently belongs.
The vehicle-mounted operating system in this embodiment may be any operating system among a Windows operating system, a macOS operating system, a Linux operating system, an iOS operating system, and an Android operating system, which is not limited herein; meanwhile, the audio applications configured on the vehicle-mounted operating system may include any applications having a voice playing function, such as a call application, an audio player, and a navigation application. The communication application comprises applications such as voice telephone, WeChat and QQ, the audio player comprises applications such as broadcasting, music, video and electronic book, and the navigation application has a road condition broadcasting function.
It should be noted that, the vehicle-mounted operating system in this embodiment may be any operating system among a Windows operating system, a macOS operating system, a Linux operating system, an iOS operating system, and an Android operating system, which is not limited in this embodiment of the present invention; meanwhile, the audio applications configured on the vehicle-mounted operating system may include any applications having a voice playing function, such as a call application, an audio player, a traffic report application, and the like.
In this embodiment, the audio focus service is configured in the audio focus server, and no audio application may be configured in the operating system where the audio focus service is located. The audio focus service AudioFocus service can directly provide a set of complete AudioFocus mechanism, is used for receiving an audio focus application request of a target audio application in any vehicle-mounted operating system, determining a related audio application to which an audio focus belongs currently, and feeding back an audio focus preemption result to the target audio application and the related audio application without depending on any vehicle-mounted operating system or other audio proxy services configured with the audio application, and can directly communicate with the target audio application and the related audio application so as to improve the efficiency of receiving and processing the audio focus application request of the audio application. The mode of receiving the audio focus application request of the target audio application in any vehicle-mounted operating system through the audiofocussserve is determined by the communication mode among the operating systems, and needs to be developed by system developers, for example, the audio focus application request can be obtained through a socket communication mode.
In order to ensure the accuracy of communication interaction between the main vehicle-mounted operating system and other vehicle-mounted operating systems, corresponding Audio managers are configured on the vehicle-mounted operating systems, and corresponding Audio focus interfaces (Audio Focus APIs) are developed in the Audio focus services, so that the vehicle-mounted operating systems call the Audio focus interfaces developed in the Audio focus services through the Audio managers, and thus, the communication interaction between the Audio focus services and other vehicle-mounted operating systems is realized.
In addition, in order to ensure the timeliness of the application of each audio application to the audio focus in the multiple vehicle-mounted operating systems, the embodiment requires that the audio focus service is in a real-time working state, at this time, if a certain audio application in any one vehicle-mounted operating system needs to play the corresponding audio currently, the audio application will be used as the target audio application in the embodiment, an audio manager on the vehicle-mounted operating system in which the audio application is located calls an audio focus interface developed on the main audio focus service to report the corresponding audio focus application request to the audio focus service, so that the audio focus application request reported by the target audio application can be received by the audio focus service, and after the audio focus application request is received by the audio focus service, in order to ensure the preemption accuracy of the audio focus, the associated audio application to which the audio focus currently belongs will be found out first, the associated audio application may be an audio application that is currently playing audio on any vehicle-mounted operating system, so as to accurately determine whether the target audio application can rob an audio focus from the associated audio application.
And S120, determining an audio focus preemption result of the target audio application and the associated audio application according to the playing priority of the target audio application and the associated audio application.
Specifically, after receiving an audio focus application request of a target audio application and determining a related audio application to which an audio focus belongs at present, it is necessary to determine whether the target audio application can rob away the audio focus from the related audio application, at this time, since audio categories played by different audio applications are also different, and a user may preferentially select an audio with high real-time performance for audio played simultaneously in different audio categories to play, for example, when receiving a call request while playing music, the user may select to pause playing music to answer the call, or when receiving a traffic broadcast voice while playing music in a vehicle driving process, the user may reduce the playing volume of the music to broadcast the traffic information as much as possible. Therefore, by analyzing the audio playing categories of different audio applications, the playing priorities corresponding to the audio applications on each vehicle-mounted operating system can be set, for example, the playing priority of the call application is greater than that of the audio player and the road condition broadcast application, and the playing priority of the road condition broadcast application is greater than that of the audio player.
In this embodiment, the playing priority corresponding to the audio playing type of the audio application may be set as the first priority for the voice call or the message alert tone, the playing priority corresponding to the audio playing type of the audio application may be set as the third priority for music or video music, and the playing priority corresponding to the audio playing type of the audio application may be set as the second priority for the navigation road broadcast voice.
After determining the associated audio application to which the audio focus belongs currently, firstly, finding out the playing priority of the target audio application and the associated audio application respectively, then, by comparing the playing priority between the target audio application and the associated audio application, judging whether the target audio application can preempt the audio focus from the associated audio application, and the audio application with the high playing priority can preempt the audio focus of the audio application with the low playing priority, thereby respectively determining the audio focus preemption results of the target audio application and the associated audio application, namely, the audio focus can be preempted by the audio application with the highest playing priority finally.
It should be noted that, because the audio applications in the multiple in-vehicle operating systems may report the corresponding audio focus application requests by the audio focus service at the same time, the target audio applications in this embodiment may be one or multiple, when multiple target audio applications are provided, the playing priorities of the target audio applications and the associated audio applications are still compared, and then the audio application with the highest playing priority in the target audio applications and the associated audio applications preempts the audio focus, so that the audio application with the highest playing priority plays the corresponding audio, and the audio application without preempting the audio focus does not play the audio, thereby avoiding the noisy audio playing between the multiple in-vehicle operating systems.
According to the technical scheme of the embodiment, when an audio focus application request of a target audio application in any vehicle-mounted operating system is received through an audio focus service, a related audio application to which an audio focus belongs at present is determined, and then audio focus preemption results of the target audio application and the related audio application are re-determined according to the playing priority of the target audio application and the related audio application, so that a commonly-followed audio focus mechanism is realized on multiple vehicle-mounted operating systems, and audio is coordinately played among the multiple vehicle-mounted operating systems; and the audio focus service is adopted to directly receive the audio focus and feed back the preemption result, so that the efficiency of receiving and processing the audio focus related request is improved.
Example two
Fig. 2 is a flowchart of an audio focus playback control method in a second embodiment of the present invention, where the present embodiment is optimized based on the foregoing embodiment, and in the present embodiment, after determining an audio focus preemption result of the target audio application and the associated audio application, the method further includes: and feeding back corresponding audio focus preemption results to the target audio application and the associated audio application respectively so as to enable the target audio application and the associated audio application to execute corresponding audio playing operation according to the corresponding audio focus preemption results respectively.
As shown in fig. 2, the method of this embodiment specifically includes the following steps:
s210, if an audio focus application request of a target audio application in any vehicle-mounted operating system is received through the audio focus service, determining the associated audio application to which the audio focus currently belongs.
S220, determining the audio focus preemption result of the target audio application and the associated audio application according to the playing priority of the target audio application and the associated audio application.
And S230, feeding back corresponding audio focus preemption results to the target audio application and the associated audio application respectively, so that the target audio application and the associated audio application execute corresponding audio playing operation according to the corresponding audio focus preemption results respectively.
Specifically, after determining the audio focus preemption results of the target audio application and the associated audio application, in order to ensure that the audio in the audio application is accurately played, the embodiment may also feed back the corresponding audio focus preemption results to the target audio application and the associated audio application, and when the target audio application preempts the audio focus from the associated audio application, that is, the associated audio application does not preempt the audio focus, the target audio application may be caused to play the corresponding audio, and when the associated audio application loses the audio focus, the audio playing may be exited or paused or the volume of the audio playing may be reduced, so that the user focuses on the audio played by the target audio application; and when the target audio application does not preempt the audio focus from the associated audio application, that is, the associated audio application still preempts the audio focus, the target audio application will not play the audio, and the associated audio application continues to play the corresponding audio. Preferably, the target application does not preempt the audio focus, and can receive a prompt message to remind the user that the audio focus is occupied and the audio is not allowed to be played temporarily.
Optionally, after determining the audio focus preemption results of the target audio application and the associated audio application, the method further includes:
and if the associated audio application is not empty and the associated audio application does not preempt the audio focus, setting an audio playing coordination parameter of the associated audio application under the condition that the audio focus is not preempted according to the audio playing type of the target audio application which preempts the audio focus.
Specifically, in order to ensure the audio playing performance of the associated audio application, if the associated audio application is not empty and the associated audio application does not preempt the audio focus, the audio playing coordination parameter of the associated audio application under the condition that the audio focus is not preempted is set according to the audio playing type of the target audio application which has preempted the audio focus; and feeding back the audio playing coordination parameters under the condition that the audio focus is not preempted to the associated audio application so that the associated audio application executes corresponding audio playing operation according to the audio playing coordination parameters under the condition that the audio focus is not preempted.
Illustratively, the audio playing type of the target audio application which preempts the audio focus is a voice telephone, the associated application is an audio player, the audio playing coordination parameter of the audio player under the condition that the audio focus is not preempted is set as pause playing, and if the audio player does not preempt the audio focus for a long time, the audio playing coordination parameter is set as quit playing; and if the audio playing type of the target audio application which preempts the audio focus is the road condition broadcast voice, and the associated application is the audio player, setting the audio playing coordination parameter of the audio player under the condition that the audio focus is not preempted to be reduced in volume.
Optionally, after the setting of the audio playing parameter of the associated audio application that does not preempt the audio focus, the method further includes:
and feeding back the audio playing coordination parameters under the condition that the audio focus is not preempted to the associated audio application so that the associated audio application executes corresponding audio playing operation according to the audio playing coordination parameters under the condition that the audio focus is not preempted.
Specifically, if the associated audio application is not empty and the associated audio application does not occupy the audio focus, it indicates that the associated audio application is not focused by the user at present, and when the target audio application which occupies the audio focus plays the corresponding audio, because the audio playing types are different, the playing requirements for the associated audio application which does not occupy the audio focus are also different, for example, if the call application occupies the audio focus from the music player, the music player is required to pause playing the audio in order to ensure the call quality, and if the road condition broadcast application occupies the audio focus from the music player, the music player is only required to reduce the volume of audio playing, so that the road condition does not affect the definition of the broadcast voice; therefore, in this embodiment, after determining that the associated audio application is not empty and the associated audio application does not preempt the audio focus, the audio play coordination parameter of the associated audio application under the condition that the audio focus is not preempted is set by analyzing the audio play type of the target audio application that has preempted the audio focus this time, and the audio play coordination parameter can indicate that the associated audio application needs to quit audio play or pause audio play when the audio focus is not preempted, or only needs to reduce the volume of audio play; then, when the corresponding audio focus preemption result is fed back to the associated audio application, the audio play coordination parameter of the associated audio application under the audio focus not preempted is also fed back synchronously, so that the associated audio application directly executes the corresponding audio play operation according to the audio play coordination parameter under the audio focus not preempted, and the audio play is not required to be quitted each time the audio focus is not preempted, thereby ensuring the play performance of the associated audio application.
Optionally, after determining the audio focus preemption results of the target audio application and the associated audio application, the method further includes:
if the associated audio application is not empty and an audio focus release notification is received by the audio focus service for a target audio application that has preempted audio focus, then the current audio focus continues to be assigned to the associated audio application.
Specifically, if the associated audio application is not empty and the associated audio application does not preempt the audio focus, which means that the target audio application preempts the audio focus, the target audio application plays the corresponding audio, at this time, after the audio playing is completed, the target audio application communicates with the audio focus interface on the audio focus service through the audio manager on the vehicle-mounted operating system, so as to report a corresponding audio focus release notification to the audio focus service, at this time, if the audio focus release notification of the target audio application that has preempted the audio focus is received through the audio focus service, in order to ensure the continuity of the audio playing, when the associated audio application does not quit the last audio playing, the current audio focus is directly continuously allocated to the associated audio application, so that the associated audio application continuously plays the last audio.
Illustratively, if the target application is a call application and the target application is a navigation application, the call application occupies an audio focus, the navigation application reduces the volume broadcast if the navigation application does not occupy the audio focus, the corresponding audio focus release notification is reported to the audio focus service when the call application is finished, the navigation application receives the notification that the call application releases the audio focus, directly occupies the current audio focus, and resumes to the volume before reducing the volume to continue broadcasting the road condition.
Optionally, after the current audio focus is continuously allocated to the associated audio application, the method further includes:
and feeding back successful preemption information of the audio focus to the associated audio application so as to enable the associated audio application to continue to execute corresponding audio playing operation according to the audio playing default parameters.
Specifically, after the current audio focus is continuously allocated to the associated audio application, the successful preemption information of the audio focus is fed back to the associated audio application, so that the associated audio application can continuously execute the corresponding audio playing operation according to the audio playing default parameter, and the audio playing default parameter can indicate the audio playing standard of the associated audio application when the audio focus is preempted, for example, the playing volume of the audio player is reduced during the road condition broadcast, and the audio player continues to play music by adopting the original volume after the road condition broadcast is finished.
Optionally, the method further includes:
and receiving the audio focus processing message of any audio application in each vehicle-mounted operating system in real time through the audio focus service instance.
Specifically, in order to ensure real-time operation of the audio focus service, the embodiment receives, in real time, an audio focus processing message of any audio application in each vehicle-mounted operating system through an audio focus service instance, where the audio focus processing message may be various types of audio focus related information such as an application request, a release notification, and a change state of an audio application for an audio focus.
As shown in fig. 2a, the technical solution of this embodiment includes the following specific steps: the audio focus service can be configured in any operating system or independently configured in an operating system except the operating system carrying any audio application, and if an audio focus application request of a target audio application in any vehicle-mounted operating system is received through the audio focus service, the associated audio application to which the audio focus belongs currently is determined; and determining an audio focus preemption result of the target audio application and the associated audio application according to the playing priority of the target audio application and the associated audio application, and if the associated audio application is not empty and the associated audio application does not preempt an audio focus, setting an audio playing coordination parameter of the associated audio application under the condition that the audio focus is not preempted to be fed back to the associated audio application according to the audio playing type of the target audio application which preempts the audio focus, so that the associated audio application executes corresponding audio playing operation according to the audio playing coordination parameter under the condition that the audio focus is not preempted to be played.
When an audio focus application request of a target audio application in any vehicle-mounted operating system is received through an audio focus service, firstly, a related audio application to which an audio focus belongs at present is determined, and then, according to the playing priority of the target audio application and the related audio application, the audio focus preemption result of the target audio application and the related audio application is re-determined, so that a commonly-obeyed audio focus mechanism is realized on multiple vehicle-mounted operating systems, and audio among the multiple vehicle-mounted operating systems is played in a coordinated manner; and the audio focus service is adopted to directly receive the audio focus and feed back the preemption result, so that the efficiency of receiving and processing the audio focus related request is improved.
