Referring to fig. 3, an embodiment of a play control method of the present application is provided. In this embodiment, based on a play control system, the play control system includes an application layer, an intermediate layer, a driver layer, and a hardware layer, and the play control method includes:
step S10, a first request instruction corresponding to a first target application is sent to the middle layer through the application layer, wherein the first request instruction is an instruction for the first target application to request to play first audio and video data;
the first audio and video data specifically includes audio data and/or video data that the first target application needs to play currently. The first audio and video data can be data collected by the playing terminal in real time and can also be data acquired by the playing terminal from external equipment.
The first target application is specifically an application with a real-time audio and video data output requirement in the playing terminal. For example, the first target application may be a KTV application, a teleconferencing application, or the like. The cast terminal may be installed with one or more first target applications.
In this embodiment, a driver layer calls a data interface of a hardware layer to acquire audio data acquired by a microphone in real time, the driver layer sends the acquired audio data to a first target application in an application layer in real time, the audio data acquired by the first target application from the driver layer can be used as first audio/video data, and the application layer can send a first request instruction in real time when the first target application receives the first audio/video data.

the middle layer is used for managing the priority and audio playing permission of each audio and video data (including audio and video data of music, radio stations, video and other applications) according to a preset strategy.
After receiving the first request instruction, the intermediate layer may determine whether to allow playing of the first audio/video data according to a preset policy, for example, whether the current time is within a preset time period in which playing is allowed, whether the priority of the first audio/video data is highest in all audio/video data to be played, and the like.
And when the middle layer determines that the first audio and video data is not allowed to be played, a playing permission instruction can be returned to the application layer, and when the middle layer determines that the first audio and video data is not allowed to be played, a playing prohibition instruction can be returned to the application layer.
Step S30, when the application layer receives the play permission instruction of the middle layer, the first audio/video data is sent to the driving layer;
specifically, the application layer and the driver layer may pre-establish a communication channel, and the application layer may send the first audio/video data to the driver layer in real time based on the communication channel when receiving the play permission instruction.
It should be noted that the application layer does not send the first audio/video data to the intermediate layer, and sends a communication instruction, where the transmission efficiency of the communication instruction is greater than that of the first audio/video data.
In addition, when the application layer receives a playing prohibition instruction returned by the middle layer, the application layer prohibits sending the first audio and video data to the drive layer.
And step S40, controlling the hardware layer to play the first audio and video data when the first audio and video data is received through the driving layer.
And after receiving the first audio and video data, the driving layer can call a corresponding interface in the hardware layer to control a loudspeaker in the hardware layer to play the first audio and video data.

Further, based on the above embodiment, another embodiment of the playback control method of the present application is provided. In this embodiment, referring to fig. 4, after step S40, the method further includes:
step S50, when receiving a first play switching instruction through the intermediate layer, sending a play pause instruction corresponding to the first target application to the application layer;
the first play switching instruction may be specifically sent while the second target application sends the second audio/video data to be played to the intermediate layer when receiving an instruction input by a user, or sent to the intermediate layer when the driver layer detects that the hardware layer has a play switching instruction input by the user.
Step S60, pausing sending the first audio/video data to the driver layer by the application layer when receiving the play pause instruction, so that the driver layer controls the hardware layer to pause playing the first audio/video data;
the first playing switching instruction is used for switching the first audio and video data currently played by the hardware layer to playing audio and video data of a second target application, and the second target application is an application with an audio and video playing function except the first target application.
In this embodiment, through the above manner, when a user needs to switch from the first audio/video data of the first target application to the audio/video data of another application for playing, the audio/video data playing of the first target application can be paused in time according to the user, so that the audio/video data playing delay of the first target application is ensured to be small, the user needs to be paused accurately, and the terminal audio/video playing function is further ensured to meet the user needs.
Further, based on any of the above embodiments, another embodiment of the playback control method of the present application is provided. In this embodiment, referring to fig. 5, before the step S30, the method further includes:
step S01, when the first request instruction is not received through the intermediate layer, if a second play switching instruction is received, sending the play permission instruction to the application layer;
the second playing switching instruction is used for switching the currently played audio and video data of the hardware layer to play the first audio and video data.
The second play switching instruction may specifically be sent to the intermediate layer when the driver layer detects that the hardware layer has a play switching instruction input by the user, or may also be sent when the second target application corresponding to the currently played audio/video data of the hardware layer receives the instruction input by the user and sent by the driver layer.
In this embodiment, by the above manner, when a user needs to switch from other audio and video data to the first audio and video data of the first target application for playing, the first audio and video data of the first target application can be played in time according to the user, so that the audio and video data of the first target application can be played accurately while the playing delay is small, and the audio and video playing function of the terminal can be further ensured to meet the user requirements.
Further, based on any of the above embodiments, a further embodiment of the playback control method of the present application is provided. In this embodiment, referring to fig. 6, the step of determining whether to allow the first audio/video data to be played in step S20 includes:
step S21, acquiring a second priority value corresponding to second audio/video data of a currently received second target application, and acquiring a first priority value corresponding to the first audio/video data, wherein the second target application is an application with an audio/video playing function except the first target application;
the first priority value and the second priority value may be fixed values pre-stored in the intermediate layer, or may be values determined according to characteristics of audio/video data actually received by the intermediate layer.
There may be one or more than one second audio-visual data of the second target application received by the intermediate layer. The second audio and video data received by the middle layer can be understood as audio and video data to be played in the middle layer.
Step S22, determining whether to allow the first audio/video data to be played according to a magnitude relationship between the first priority value and the second priority value.
Specifically, when the first priority value is greater than the second priority value, it is determined that the first audio/video data is allowed to be played; and when the first priority value is smaller than the second priority value, determining that the first audio and video data is not allowed to be played.
When more than one second audio/video data exists and the first priority value is greater than all the second priority values, the first audio/video data can be determined to be allowed to be played; and when the first priority value is smaller than any one of the second priority values, determining that the first audio and video data is not allowed to be played.
In this embodiment, in the above manner, the intermediate layer may compare the playing priority between the first audio/video data and the second audio/video data to be played in the intermediate layer based on the first priority and the second priority, and determine whether to allow the playing of the first audio/video data based on the priorities of all the audio/video data to be played, so as to ensure that the playing of the first audio/video data can be coordinated with the playing of other audio/video data, further improve the ordering of the overall audio/video playing of the terminal while ensuring that the audio/video application playing delay is small, and further ensure that the audio/video playing function of the terminal can meet the user requirements.
Further, in this embodiment, before the step S22 and after the step S21, a corresponding virtual identifier may be generated according to the first request instruction and associated with the first priority value, and a corresponding audio/video identifier may be generated according to the second audio/video data and associated with the second priority value. Based on this, step S22 includes: sorting the virtual identifiers and the audio/video identifiers according to the principle that the first priority value and the second priority value are from large to small to obtain a play control list; and when the mark with the top sequence in the play control list is the virtual mark, determining that the first audio and video data is allowed to be played.
When the mark which is ranked the top in the play control list is not the virtual mark, the first audio and video data can be determined not to be allowed to be played.
Specifically, different first target applications may correspond to different first request instructions. And generating a corresponding virtual identifier according to the first request instruction, wherein the virtual identifier can be used for representing first audio and video data of the corresponding first target application. The audio/video identifier is specifically used for representing second audio/video data to be played in the middle layer.
The number of the second audio/video data received by the middle layer can be more than one, the first priority value and all the second priority values can be compared in pairs, the virtual identification and the audio/video identification are sorted based on the comparison result, and the larger the numerical value is, the earlier the sorting of the identification associated with the numerical value in the play control list is.
For example, the first target application is a KTV application, the first audio/video data is a sound source of the KTV application, the virtual identifier is M, the corresponding first priority value is a1, the second target application includes a radio station application and a teleconference application, the second audio/video data includes audio data of the radio station application and conference data of the teleconference application, the corresponding audio/video identifier is P, Q in sequence, the corresponding second priority values are a2 and a3 in sequence, and if a3> a1> a2, the play control list is as follows:
based on this, if the Q as the audio-video identifier is the top in rank, it may be determined that the first audio-video data is not allowed to be played.
If the first target application is a KTV application, the first audio and video data is a sound source of the KTV application, the virtual identifier is M, the corresponding first priority value is b1, the second target application is a radio station application, the second audio and video data includes audio data of the radio station application, the corresponding audio and video identifier is P, the corresponding second priority value is b2, and b1> b2, then the play control list is as follows:
| priority value | Identification |
| b1 | P |
| b2 | M |
Based on this, the first audio-video data may be determined to be allowed to be played if P as the virtual identifier is ranked first.
In this embodiment, the intermediate layer generates a virtual identifier of the first audio/video data based on the first request instruction, and performs sorting based on priority values with audio/video identifiers of other to-be-played second audio/video data in the intermediate layer to obtain a play control list, and the intermediate layer may allow playing of the first audio/video data only when the virtual identifier is sorted most in the play control list, so as to ensure that the intermediate layer can implement a comprehensive planning of playing of all audio/video data including the first audio/video data based on the virtual identifier even if the application layer does not send the first audio/video data to the intermediate layer to ensure that the playing delay is small, thereby further improving the ordering and coordination of playing of the first audio/video data and other audio/video data, and ensuring that the playing function of the playing terminal can accurately meet the user use requirements.
Further, in this embodiment, the step of obtaining a second priority value corresponding to second audio/video data of a currently received second target application includes: determining the data type of the second audio and video data; and determining the second priority value according to the data type.
The data types may include real-time call data, real-time video data, recorded data, conference data, and/or KTV data, among others. The different data types correspond to different second priority values. It should be noted that the second priority values are different when the data types are different in the same application.
The corresponding relation between the data type and the second priority value can be a preset fixed relation, the corresponding relation determined by user setting parameters can also be obtained, the use frequency of the audio and video data corresponding to the data type in advance at the current moment can also be obtained, and the corresponding relation between the data type and the second priority value is obtained according to the use frequency. Based on the corresponding relation, a second priority value corresponding to the current data type can be determined.
In this embodiment, since the user has different use requirements for audio and video data of different data types, the second priority value of the second audio and video data is determined based on the data type, so that the matching degree of the audio and video playing function of the playing terminal and the user requirements is further improved.
Further, in this embodiment, the step of obtaining the first priority value corresponding to the first audio/video data includes: acquiring a first preset weight of the first target application and second preset weights of second target applications corresponding to all currently received second audio and video data; and calculating the first priority value according to the first preset weight value and all the second preset weight values.
The first preset weight is specifically a preset weight of the playing priority of the first target application in all applications in the control terminal. The second preset weight is specifically a preset weight of a playing priority of a corresponding second target application in all applications in the control terminal.
The first preset weight and the second preset weight are specifically pre-stored in the middle layer.
In this embodiment, a sum of the first preset weight and all the second preset weights is calculated, a ratio of the first preset weight to the sum is calculated, and a product of the ratio and the reference weight is calculated as the first priority. In other embodiments, the average value of all the second preset weights is also calculated, the difference value between the first preset weight and the average value is calculated, and the calculation result obtained by subtracting the difference value from the maximum value of all the second preset weights is used as the first priority weight.
