[0084] 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.

[0085] With the popularity of electronic devices such as smartphones and tablets, more and more people are using the rich functions provided by these electronic devices. Among them, video processing functions such as video playback, video recording, and video calls are becoming more and more popular. However, as electronic devices become better and more functional, people use electronic devices more and more frequently, and the power consumption of electronic devices is also increasing.

[0086] For example, when an application that provides a video processing function switches from the foreground to the background, it will continue to perform video encoding and decoding in the background, causing the electronic device to continue to consume power. On the other hand, in order to ensure the operating performance of the application that provides the video processing function, the CPU frequency of the electronic device is usually set higher. However, a higher CPU frequency will result in higher power consumption, and sometimes only a few applications may be running in an electronic device (for example, only one video playback application, etc.), and the electronic device does not need to have high computing performance, resulting in a waste of power in the electronic device.

[0087] In view of this, the present disclosure provides the following power consumption control method, apparatus, device and storage medium, which can improve the battery life of electronic devices by accurately identifying different video scenes of electronic devices and controlling the power consumption of electronic devices based on different video scenes, thereby improving the user experience.

[0088] Figure 1 is a flow chart of a power consumption control method according to an exemplary embodiment; the method of this embodiment can be executed by a power consumption control device, which can be configured in an electronic device, such as a server, a workstation, a personal computer, a mobile terminal (such as a mobile phone, a tablet computer, etc.), a wearable device (such as glasses, a watch, etc.), etc. Figure 1 As shown, the method includes the following steps S101-S103:

[0089] In step S101, the number of codec instances of each application in the electronic device is detected.

[0090] In this embodiment, the electronic device can detect the number of codec instances of each application installed in the electronic device based on a set period.

[0091] The above-mentioned number of codec instances may include a first number of encoder instances and / or a second number of decoder instances.

[0092] It can be understood that the above-mentioned applications may be applications that need to use media codecs (MediaCodec) to perform video processing tasks such as video playback, video recording, video calls, and video transcoding. When performing corresponding video processing tasks, these programs need to create codec instances (i.e., encoder instances and / or decoder instances).

[0093] In some embodiments, the electronic device may select a detection method in the related art to detect the number of codec instances of each application in the electronic device based on actual needs. This embodiment does not limit the specific detection method.

[0094] In some other embodiments, the electronic device may also be based on the following Figure 2 The method of the embodiment shown is to detect the number of codec instances of each application in the electronic device, and this embodiment will not be described in detail.

[0095] In step S102, a current video scene of the electronic device is determined based on the number of codec instances.

[0096] In this embodiment, after detecting the number of codec instances of each application in the electronic device, the electronic device may determine the current video scene of the electronic device based on the number of codec instances.

[0097] In some embodiments, conditions on the number of codec instances corresponding to various preset video scenes can be pre-set. Then, when the electronic device detects the number of codec instances of each application in the electronic device, it can determine which preset video scene the number of codec instances satisfies the condition on the number of codec instances, thereby determining the current video scene of the electronic device.

[0098] That is, the electronic device may determine that the current video scene is the preset video scene in response to the number of the codec instances satisfying a preset number condition corresponding to the preset video scene.

[0099] Exemplarily, the above-mentioned preset video scenes may include a single video scene and / or a mixed video scene. The above-mentioned single video scene may further include at least one of a video playback scene, a video recording scene, a video call scene, and a video transcoding scene; and the mixed video scene may include at least two of the above-mentioned single video scenes, such as "video playback scene + video recording scene", "video playback scene + video call scene + video transcoding scene", etc.

[0100] For example, when the number of encoder instances of an APP in an electronic device is 0 and the number of decoder instances is 1, it can be determined that the APP is playing a video; when the number of encoder instances of an APP in an electronic device is 1 and the number of decoder instances is 0, it can be determined that the APP is recording a video; when the number of encoder instances of an APP in an electronic device is 1 and the number of decoder instances is 1, it can be determined that the APP is making a video call or video transcoding.

[0101] On this basis, when there is only an application for video playback in the electronic device, but no application for video recording, video calls or video transcoding, it can be determined that the current video scene of the electronic device is a video playback scene in a single video scene (referred to as the "video playback scene" for short); similarly, when there is only an application for video recording in the electronic device, but no application for video playback, video calls or video transcoding, it can be determined that the current video scene of the electronic device is a video recording scene in a single video scene (referred to as the "video recording scene" for short), which are not listed one by one here.

[0102] When there are two or more video processing applications in an electronic device, such as an application for video playback and an application for video recording, or an application for video calls and an application for video transcoding, it can be determined that the current video scene of the electronic device is a mixed video scene, which are not listed one by one here.

[0103] In step S103, the power consumption of the electronic device is controlled based on the current video scene.

[0104] In this embodiment, after the current video scene of the electronic device is determined based on the number of codec instances, the power consumption of the electronic device may be controlled based on the current video scene.

[0105] In some embodiments, the corresponding power consumption control mode can be set in advance based on the requirements of different video scenes, and then when the electronic device determines the current video scene based on the number of codec instances, the power consumption control mode corresponding to the current video scene can be determined to adjust the performance of the electronic device or adjust the operating parameters of the application in the electronic device, so as to control the power consumption of the electronic device. Since the corresponding power consumption control mode is set in advance based on the requirements of different video scenes, the accuracy of determining the power consumption control mode can be improved, and the power consumption of the electronic device can be accurately controlled, which is conducive to reducing the power consumption of the electronic device and improving the endurance of the electronic device.

[0106] In some other embodiments, the above-mentioned method of controlling the power consumption of the electronic device based on the current video scene can also refer to the following Figures 4 to 6 The embodiment shown is not described in detail here.

[0107] As can be seen from the above description, the method of this embodiment detects the number of codec instances of each application in the electronic device, the number of codec instances including a first number of encoder instances and / or a second number of decoder instances, and determines the current video scene of the electronic device based on the number of codec instances, and then controls the power consumption of the electronic device based on the current video scene. This can accurately identify different video scenes of the electronic device, and then accurately adopt the power consumption control method corresponding to the current video scene to control the power consumption of the electronic device, which is beneficial to reducing the power consumption of the electronic device, improving the battery life of the electronic device, and then improving the user experience.

[0108] Figure 2 It is a flowchart showing how to detect the number of codec instances of each application in an electronic device according to an exemplary embodiment of the present disclosure; based on the above embodiment, this embodiment uses how to detect the number of codec instances of each application in an electronic device as an example to illustrate.

[0109] like Figure 2 As shown, the detection of the number of codec instances of each application in the electronic device in the above step S101 may include the following steps S201-S202:

[0110] In step S201, the currently updated codec identification information is obtained.

[0111] In this embodiment, when the electronic device needs to detect the number of codec instances of each application in the electronic device, the currently updated codec identification information can be obtained.

[0112] The codec identification information may be information stored in a target process (eg, ServiceC) pre-created in the electronic device, and the codec identification information may be updated based on creation and / or destruction of codec instances of each application in the electronic device.

[0113] That is to say, when an application in an electronic device creates and / or destroys its own codec instance, the codec identification information stored in the above target process can be updated accordingly, so that the number of codec instances of each application in the electronic device can be timely and accurately reflected through the updated codec identification information. Among them, the codec identification information can include the identification bit corresponding to the codec instance of each application (i.e., an application that can perform video processing tasks such as video playback and video recording). The identification bit can be used to indicate the position of the codec of each application corresponding to the above codec identification information.

[0114] For example, the above codec identification information can be a 64-bit attribute information, and every 2 bits in the attribute information can be used to indicate the identification bit corresponding to the codec instance of an APP. For example, "01" means that the APP has only created a decoder instance, "10" means that the APP has only created an encoder instance, "11" means that the APP has created both a decoder instance and an encoder instance, and "00" means that the APP has not created a decoder instance or an encoder instance.

[0115] In step S202, the number of codec instances is determined based on the codec identification information.

[0116] In this embodiment, after the currently updated codec identification information is obtained, the number of codec instances may be determined based on the codec identification information.

[0117] Still taking the codec identification information as 64-bit attribute information as an example, after obtaining the currently updated codec identification information, the number of codec instances can be determined by counting the values ​​of each identification bit of the attribute information. For example, if the codec identification information is "01100...00", the number of codec instances can be determined to be "encoder instance number 1; decoder instance number 1". For another example, if the codec identification information is "010100...00", the number of codec instances can be determined to be "encoder instance number 0; decoder instance number 2".

[0118] From the above description, it can be seen that this embodiment obtains the currently updated codec identification information and determines the number of codec instances based on the codec identification information, so as to accurately determine the number of codec instances of each application in the electronic device, and then can subsequently determine the current video scene of the electronic device based on the number of codec instances, and control the power consumption of the electronic device based on the current video scene, which is beneficial to reducing the power consumption of the electronic device, improving the battery life of the electronic device, and thus improving the user experience.

[0119] Figure 3 The flowchart of how to update the codec identification information according to an exemplary embodiment of the present disclosure is shown; based on the above embodiment, this embodiment takes how to update the codec identification information as an example for exemplary description.

[0120] like Figure 3 As shown, the power consumption control method of this embodiment may further include updating the codec identification information based on the following steps S301-S302:

[0121] In step S301, a notification message sent by a first application among the various applications when creating or destroying a first codec instance is received.

[0122] In this embodiment, when the first application creates or destroys its own codec instance (named as the first codec instance for easy distinction), a notification message can be sent to the electronic device. The notification message may include the first codec identification information corresponding to the first codec instance, and may also include the first program package name of the first application. Exemplarily, assuming that when program W creates its own decoder instance, a notification message can be sent to the electronic device, the message including the package name "W" of program W and the identification "h" corresponding to the decoder instance of program W.

[0123] In some embodiments, the electronic device may receive the above notification message based on a pre-created target process (eg, ServiceC) to obtain the package name of the application and the corresponding codec identification information.

[0124] In step S302, the current codec identification information is updated based on the first codec identification information to obtain the currently updated codec identification information.

[0125] In this embodiment, when the electronic device receives a notification message sent by the first application among the various applications when creating or destroying the first codec instance, it can update the current codec identification information based on the first codec identification bit information to obtain the currently updated codec identification information.

[0126] In some embodiments, a 64-bit integer variable A and attribute information B may be defined in Service C, both of which are 0 by default, wherein the integer variable A is the value of the attribute information B.

[0127] For example, when Service C receives the notification message sent by program W when creating a decoder instance, it can update the current codec identification information according to the identification bit "h" corresponding to the decoder instance of program W to obtain the currently updated codec identification information. For example, the current codec identification information can be updated based on the following formula (3-1):

[0128] Variable A = variable A || identification bit h corresponding to the decoder instance of program W; (3-1)

[0129] In the above formula, “||” represents the “or” operation.

[0130] For another example, when Service C receives the notification message sent by program W when destroying the decoder instance, it can update the current codec identification information according to the identification bit "h" corresponding to the decoder instance of program W to obtain the currently updated codec identification information. For example, the current codec identification information can be updated based on the following formula (3-2):

[0131] Variable A = variable A&& the identifier h corresponding to the decoder instance of program W; (3-2)

[0132] In the above formula, “&&” represents the “and” operation.

[0133] On this basis, Service C can update the value of attribute information B to variable A, that is, the currently updated codec identification information.

[0134] In some embodiments, when the electronic device receives the notification message sent by the first application, it can search for the first application in a preset whitelist based on the first package name of the first application. The whitelist includes a pre-specified video scene application. On this basis, the electronic device can respond to finding the first application in the whitelist and execute the above step S302 to update the current codec identification information based on the first codec identification information.

[0135] From the above description, it can be seen that this embodiment receives a notification message sent by the first application among the various applications when creating or destroying the first codec instance, and updates the current codec identification information based on the first codec identification information to obtain the currently updated codec identification information. This can achieve timely and accurate updating of the codec identification information, and further can achieve subsequent determination of the number of codec instances based on the codec identification information, which can improve the accuracy of determining the number of codec instances, and further can improve the accuracy of subsequent determination of the current video scene of the electronic device.

[0136] Figure 4 It is a flowchart showing how to control the power consumption of the electronic device based on the current video scene according to an exemplary embodiment of the present disclosure; based on the above embodiment, this embodiment uses how to control the power consumption of the electronic device based on the current video scene as an example to exemplify.

[0137] like Figure 4 As shown, the controlling of the power consumption of the electronic device based on the current video scene in the above step S103 may include the following steps S401-S402:

[0138] In step S401 , in response to the current video scene being the single video scene, the number of codec instances is compared with a first number threshold.

[0139] In this embodiment, after the current video scene of the electronic device is determined based on the number of codec instances, if it is detected that the current video scene is the single video scene (e.g., any one of a video playback scene, a video recording scene, a video call scene, and a video transcoding scene), the number of codec instances can be compared with a first quantity threshold.

[0140] The first quantity threshold may be set based on actual application requirements, such as being set to 1 or 2, etc., and this embodiment does not limit this.

[0141] In step S402, in response to the number of codec instances being less than or equal to the first number threshold, the current frequency of the CPU of the electronic device is reduced.

[0142] In this embodiment, after comparing the number of codec instances with the first number threshold, if the comparison result is that the number of codec instances is less than or equal to the first number threshold, the current frequency of the CPU of the electronic device can be reduced. The degree of reduction of the current frequency of the CPU of the electronic device can be set based on actual scenario requirements, such as 20% or 30%, etc., which is not limited in this embodiment.

[0143] It is understandable that a higher CPU frequency will lead to higher power consumption, and when a few applications are running in an electronic device (for example, only a video playback application is running), the electronic device does not need to have high computing performance. Therefore, this embodiment can avoid wasting power in the electronic device by reducing the current frequency of the CPU, thereby reducing the power consumption of the electronic device.

[0144] From the above description, it can be seen that this embodiment reduces the power consumption of the electronic device based on the current video scene, improves the battery life of the electronic device, and thus improves the user experience by comparing the number of codec instances with the first number threshold in response to the current video scene being the single video scene, and reducing the current frequency of the CPU of the electronic device in response to the number of codec instances being less than or equal to the first number threshold.

[0145] Figure 5A It is a flowchart showing how to control the power consumption of the electronic device based on the current video scene according to another exemplary embodiment of the present disclosure; based on the above embodiment, this embodiment uses how to control the power consumption of the electronic device based on the current video scene as an example to exemplify.

[0146] like Figure 5A As shown, the controlling the power consumption of the electronic device based on the current video scene in the above step S103 may include the following steps S501-S502:

[0147] In step S501, in response to the current video scene being the video playing scene or a mixed video scene including the video playing scene, the running state of the second application currently playing the video is detected.

[0148] In this embodiment, after the current video scene of the electronic device is determined based on the number of codec instances, if it is detected that the current video scene is the video playback scene (e.g., a scene in which only a video playback application is running) or a mixed video scene that includes the video playback scene (e.g., a scene in which both a video playback application and a video recording, video call and / or video transcoding application are running), the running status of the application currently playing the video (named the second application for easy distinction) can be detected.

[0149] The running status of the above application may include a foreground running status and a background running status.

[0150] It is worth noting that the detection method of the running status of the above-mentioned application can be selected from relevant technologies based on actual needs, and this embodiment does not limit this.

[0151] In step S502, in response to detecting that the running state of the second application is switched from the foreground running state to the background running state, the codec instance of the second application is frozen.

[0152] In this embodiment, after detecting the running state of the second application currently playing the video, if it is detected that the running state of the second application is switched from the foreground running state to the background running state, the codec instance of the second application can be frozen.

[0153] The above-mentioned method of freezing the codec instance of the second application may include, but is not limited to, discarding the data stream output by the codec.

[0154] For example, Figure 5B FIG. 1 is a schematic diagram of a system framework according to an exemplary embodiment of the present disclosure. Figure 5B As shown, normally, when the second application needs to play a video, the video data (Bit stream) is sent to the electronic device to create a codec instance (hereinafter referred to as the second codec instance for ease of distinction) for decoding the video data through the electronic device, such as by calling the initialization interface (init interface) and configuration interface (config interface) of the media codec (MediaCodec) and codec2.0 (a preset software architecture for creating a decoder) to create the second codec instance.

[0155] After the creation of the second codec instance is completed, the video data (Bit stream) can be decoded based on the second codec instance, and the decoded Bit stream is passed to Figure 5B The components in the dotted boxes in the figure are further processed. However, in the related art, when the application that plays the video switches from the foreground running state to the background running state, the components in the dotted boxes in the figures will continue to process the bit stream passed from the second codec instance, but the screen of the electronic device will not display the processed video data at this time, which results in the processing of these video data in vain and also results in the waste of electric energy of the electronic device. Therefore, after detecting that the running state of the application that currently plays the video switches from the foreground running state to the background running state, this embodiment freezes the second codec instance of the application, such as preventing the second codec instance from passing the processed bit stream downward, or preventing the second codec instance from passing the processed bit stream downward. Figure 5BThe VideoHAL component in the dotted box discards the bit stream transmitted by the second codec instance, thereby preventing the various layer components in the dotted box from continuing to process the bit stream transmitted by the second codec instance, thereby avoiding the waste of electric energy of the electronic device, thereby reducing the power consumption of the electronic device and improving the battery life of the electronic device.

[0156] From the above description, it can be seen that this embodiment detects the running status of the second application currently playing the video in response to the current video scene being the video playback scene or a mixed video scene including the video playback scene, and freezes the codec instance of the second application in response to detecting that the running status of the second application switches from the foreground running state to the background running state. This can achieve freezing the codec of the background running application based on the current video scene, thereby reducing the power consumption of the electronic device, improving the battery life of the electronic device, and further improving the user experience.

[0157] Figure 6 It is a flowchart showing how to control the power consumption of the electronic device based on the current video scene according to another exemplary embodiment of the present disclosure; based on the above embodiment, this embodiment uses how to control the power consumption of the electronic device based on the current video scene as an example to exemplify.

[0158] like Figure 6 As shown, the controlling the power consumption of the electronic device based on the current video scene in the above step S103 may include the following steps S601-S602:

[0159] In step S601, in response to the current video scene being the single video scene and detecting that a third application in the electronic device is creating a third codec, the number of codec instances is compared with a second number threshold.

[0160] In this embodiment, after the current video scene of the electronic device is determined based on the number of codec instances, if it is detected that the current video scene is the single video scene (e.g., any one of a video playback scene, a video recording scene, a video call scene, and a video transcoding scene), and it is detected that a third application in the electronic device is creating a third codec (e.g., a notification message sent by the third application when creating a third codec is received), the number of codec instances can be compared with a second number threshold.

[0161] Among them, the above-mentioned second quantity threshold can be set based on actual application requirements, such as being set to an integer greater than or equal to 2, etc., which is not limited in this embodiment.

[0162] In step S602, in response to the number of codec instances being greater than or equal to the second number threshold, a performance parameter of the third codec is reduced.

[0163] In this embodiment, after comparing the number of codec instances with the second number threshold, if the comparison result is that the number of codec instances is greater than or equal to the second number threshold, the performance parameter of the third codec may be reduced. The above performance parameter may include resolution and / or frame rate.

[0164] It is worth noting that the extent of reducing the performance parameters of the third codec can be set based on actual scenario requirements, such as being set to 20% or 30%, etc., which is not limited in this embodiment.

[0165] It is understandable that the higher the performance parameter of the third codec, the higher the requirement for hardware performance and the higher the power consumption. Therefore, this embodiment can ensure the hardware performance of the electronic device by reducing the performance parameter of the third codec, avoid the problem of video playback, video recording, video call or video transcoding error caused by exceeding the hardware performance, and reduce the power consumption of the electronic device.

[0166] In other embodiments, the electronic device may also reduce the performance parameters of the third codec in response to the current video scene being the mixed video scene and detecting that a third application in the electronic device is creating a third codec. It is understandable that since the mixed video scene includes at least two of the single video scenes, the number of codec instances in the mixed video scene is also more than 2. Therefore, in order to avoid the error problem caused by exceeding the hardware performance, the performance parameters of the third codec may be reduced when the current video scene is detected to be the mixed video scene and the third application in the electronic device is detecting that the third codec is being created.

[0167] From the above description, it can be seen that this embodiment, in response to the current video scene being the single video scene and detecting that the third application in the electronic device is creating a third codec, compares the number of codec instances with the second number threshold, and then in response to the number of codec instances being greater than or equal to the second number threshold, reduces the performance parameters of the third codec. This can achieve reducing the performance parameters of the third codec based on the current video scene, ensure the hardware performance of the electronic device, avoid video playback, video recording, video calls or video transcoding errors caused by exceeding hardware performance, and reduce the power consumption of the electronic device, improve the battery life of the electronic device, and thus improve the user experience.
