[0052] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0053] Figure 1 is a flowchart of an audio playback control method according to an exemplary embodiment; the method of this embodiment can be executed by an audio playback control device, which can be configured in a first electronic device with a Linux operating system (such as a Bluetooth headset, a Bluetooth speaker, glasses, a wearable device such as a watch, etc.), and the Linux operating system is provided with a Bluedroid protocol stack. Specifically, Figure 1 As shown, the method includes the following steps S101-S103:

[0054] In step S101, an audio playback control event is obtained based on the Bluedroid protocol stack;

[0055] In some embodiments, the audio playback control event may be an audio playback control event triggered by a preset function button on a first electronic device (e.g., a Bluetooth headset), or may be an audio playback control event triggered by an application installed on a second electronic device (i.e., a central device with the first electronic device as a slave device, such as a smart phone, etc.). In step S102, the audio playback control event is read from the Bluedroid protocol stack based on a preset kernel module of the Linux operating system.

[0056] For example, when the audio playback control event is an audio playback control event triggered by a preset function button on the first electronic device, the first electronic device can read the audio playback control event from the Bluedroid protocol stack based on the preset kernel module.

[0057] In the case where the audio playback control event is an audio playback control event triggered by an application installed on the second electronic device, the first electronic device can respond to a notification received from the application in the second electronic device based on the Bluetooth service, write the audio playback control event in the preset kernel module based on the Bluetooth service, and then read the written audio playback control event based on the preset kernel module.

[0058] As an example, the preset kernel module may be a kernel Uinput module of a Linux operating system, which is not limited in this embodiment.

[0059] In step S103, based on the preset kernel module, the Bluetooth service of the Linux operating system is controlled to execute the audio playback control operation corresponding to the audio playback control event.

[0060] In this embodiment, after the audio playback control event is obtained based on the preset kernel module of the Linux operating system, the first electronic device can control the Bluetooth service of the Linux operating system to perform the audio playback control operation corresponding to the audio playback control event based on the preset kernel module.

[0061] In some embodiments, the above-mentioned method of controlling the Bluetooth service of the Linux operating system to perform the audio playback control operation corresponding to the audio playback control event can also be referred to as follows: Figure 2 The illustrated embodiment will not be described in detail here.

[0062] In other embodiments, after the Bluetooth service of the Linux operating system is controlled to perform the audio playback control operation corresponding to the audio playback control event, the first electronic device can also respond to the Bluetooth service to complete the audio playback control operation, read the current event in the preset kernel module based on the input management module (Input Manager module), and wake up the user interface based on the AMS process management service of the Linux operating system to display the display information corresponding to the current event. Exemplarily, the display information may include audio playback status information (such as play, pause, double speed playback, etc.) and / or volume information (such as volume bar information).

[0063] From the above description, it can be seen that the method of this embodiment obtains an audio playback control event based on the Bluedroid protocol stack; a control event reading module is used to read the audio playback control event from the Bluedroid protocol stack based on the preset kernel module of the Linux operating system, and based on the preset kernel module, control the Bluetooth service of the Linux operating system to perform an audio playback control operation corresponding to the audio playback control event. Since the interaction between the Bluedroid protocol stack and the audio protocol stack of the Linux operating system is realized with the preset kernel module of the Linux operating system as the interaction center, Bluetooth audio playback control can be realized on an electronic device with a Linux operating system and a Bluedroid protocol stack.

[0064] Figure 2 is a flowchart showing how to control the Bluetooth service of the Linux operating system to perform an audio playback control operation corresponding to the audio playback control event according to an exemplary embodiment of the present disclosure;

[0065] Based on the above embodiment, this embodiment uses how to control the Bluetooth service of the Linux operating system to execute the audio playback control operation corresponding to the audio playback control event as an example to exemplify the description.

[0066] like Figure 2 As shown, the above step S102 of controlling the Bluetooth service of the Linux operating system to perform the audio playback control operation corresponding to the audio playback control event may include the following steps S201-S202:

[0067] In step S201, the audio playback control event in the preset kernel module is read by the Weston input management module based on the Linux operating system.

[0068] In this embodiment, after the audio playback control event is obtained based on the preset kernel module of the Linux operating system, the first electronic device can read the audio playback control event in the preset kernel module based on the Weston input management module (WestonInput) of the Linux operating system.

[0069] Among them, Weston can be a display service implemented based on the Wayland protocol, which is responsible for processing the information of the input device and generating corresponding output.

[0070] In step S202, the audio playback control event is transmitted to the player application of the Linux operating system based on the Weston input management module, so as to send a notification message to the Bluetooth service through the player application.

[0071] In this embodiment, after the Weston input management module based on the Linux operating system reads the audio playback control event in the preset kernel module, the audio playback control event can be passed to the player application of the Linux operating system based on the Weston input management module, so as to send a notification message to the Bluetooth service through the player application, so that the Bluetooth service can be controlled to perform the audio playback control operation based on the notification message.

[0072] For example, when a notification message is sent to the Bluetooth service through the player application, the player interface layer of the player application may be called so that the player interface layer sends the notification message to the Bluetooth service based on an inter-process communication method.

[0073] It is worth noting that the above-mentioned inter-process communication mode can be set based on the needs of the actual application scenario, such as being set to one or a combination of Topic communication, Restful communication and Socket communication, and this embodiment does not limit this.

[0074] From the above description, it can be seen that this embodiment reads the audio playback control event in the preset kernel module through the Weston input management module based on the Linux operating system, and passes the audio playback control event to the player application of the Linux operating system based on the Weston input management module, so as to send a notification message to the Bluetooth service through the player application. It can be realized that based on the above notification message, the Bluetooth service can be controlled to perform the audio playback control operation, thereby realizing Bluetooth audio playback control on an electronic device with a Linux operating system and a Bluedroid protocol stack.

[0075] The audio playback control method of the present disclosure is described below with a specific embodiment, but is not intended to limit the scope of the present disclosure.

[0076] Figure 3 is a schematic diagram of a Linux operating system provided with a Bluedroid protocol stack according to an exemplary embodiment of the present disclosure; Figure 3 The Linux operating system shown in the figure, the audio playback control method of this embodiment may include the following steps:

[0077] 1) In the Linux operating system, complete the transplantation of the Bluedroid protocol stack, that is, Figure 3 In the Bluedroid cutting and transplanting status shown in the figure, Bluedroid and A2DP / AVRCP are in a conductive state, where A2DP is the Advanced Audio Distribution Profile and AVRCP is the Audio / Video Remote Control Profile.

[0078] 2) When the play / pause, previous / next song, volume up / down and other control buttons are pressed on the Bluetooth audio device (such as Bluetooth headset, etc., the following takes Bluetooth headset as an example), the Uinput module of the kernel of Bluedroid and Linux operating system can read the corresponding event:

[0079] 2.1) When the above events are playback control events such as play / pause or previous / next song, the corresponding events in the kernel Uinput module can be read through the Weston Input module to call the inter-process communication method in the interface layer adapted in the player application to notify the Bluetooth service, thereby updating the Bluetooth audio state machine through the Bluetooth service. Among them, the Bluetooth audio state machine is a state machine maintained by the Bluetooth service. Exemplarily, the content of the state machine can include states such as standby / play / pause / fast forward and rewind. In addition, the corresponding events in the kernel Uinput module can also be read through the input management module (Input Manager) to wake up the user interface UI in the process management service AMS for display, such as displaying the audio playback status.

[0080] 2.2) When the above event is a volume adjustment event such as volume increase / decrease, the corresponding event in the kernel Uinput module can be read through the WestonInput module to call the inter-process communication method in the interface layer adapted in the player application to notify the Bluetooth service, thereby updating the volume of the Bluetooth audio device through the Bluetooth service. In addition, the corresponding event in the kernel Uinput module can also be read through the input management module (Input Manager) to wake up the user interface UI in the process management service AMS for display, such as displaying a volume bar.

[0081] In other embodiments, when a central device (such as a smart phone, etc.) with the above-mentioned Bluetooth headset as a slave device presses a virtual button such as pause / play of audio and video on an application, the application can notify the Bluetooth service through inter-process communication, and then the Bluetooth service can write a corresponding event (event) to the kernel Uinput module to achieve playback control of the slave device (i.e., the above-mentioned Bluetooth headset). For example, the Bluedroid protocol stack obtains "play / pause or previous / next song and other playback control events", and the Bluetooth service can perform the corresponding "control operation is play / pause or previous / next song and other control operations".

[0082] From the above description, it can be seen that this embodiment can support Bluetooth audio playback control functions in the Linux system and Bluedroid protocol stack platform (such as the above-mentioned Bluetooth headsets and other devices), thereby reducing the development difficulty of the underlying platform and further improving the compatibility of the platform's ecological applications.

[0083] Figure 4 is a block diagram of an audio playback control device according to an exemplary embodiment of the present disclosure; the device of this embodiment can be configured in a first electronic device (such as a Bluetooth headset, a Bluetooth speaker, a pair of glasses, a watch or other wearable device) having a Linux operating system, wherein the Linux operating system is provided with a Bluedroid protocol stack.

[0086] The control operation execution module 130 is used to control the Bluetooth service of the Linux operating system to execute the audio playback control operation corresponding to the audio playback control event based on the preset kernel module.

[0087] From the above description, it can be seen that the device of this embodiment obtains audio playback control events based on the Bluedroid protocol stack, reads the audio playback control events from the Bluedroid protocol stack based on the preset kernel module of the Linux operating system, and controls the Bluetooth service of the Linux operating system to perform the audio playback control operation corresponding to the audio playback control event based on the preset kernel module. Since the interaction between the Bluedroid protocol stack and the audio protocol stack of the Linux operating system is realized with the preset kernel module of the Linux operating system as the interaction center, Bluetooth audio playback control can be realized on an electronic device with a Linux operating system and a Bluedroid protocol stack.
