Referring to fig. 1, fig. 1 is a schematic flowchart of a video playing method according to an embodiment of the present disclosure. The video playing method provided by the embodiment of the application is applied to the electronic equipment, and the specific flow can be as follows:
In the use process of the electronic device, the video playing application program needs to decode the video and play the sound, so the power consumption of the video playing application program is higher than that of other application programs. In practical use, the video playing method provided by the mobile phone can reduce the power consumption of the electronic equipment during video playing, so that the cruising ability of the mobile phone is improved. Firstly, when the video is played on the electronic equipment, the current residual electric quantity of the electronic equipment is acquired in real time.
The initial power of the electronic device is known in advance, and the electronic device may consume a certain power by running a plurality of programs installed on the electronic device or using hardware, and the electronic device may obtain the remaining power of the electronic device according to a plurality of modes, for example: in practical application, a fuel gauge is arranged inside the power supply and used for indicating the residual power of the power supply and the time that the power supply can continuously supply power under specific working conditions, wherein the fuel gauge mainly uses a voltage testing method, a battery modeling method, a coulometer and the like, and the detection method is not specifically limited herein.
In the embodiment of the application, a remaining power value is preset, after the current remaining power of the electronic device is obtained, the remaining power value is compared with the preset power value, and if the remaining power value is smaller than the preset power value, step 103 may be further executed to reduce power consumption of video playing.
In an embodiment, considering that the viewing experience of the user may be reduced when the video is continuously played by performing subsequent operations, after determining that the remaining power is less than the preset power, a prompt message may be generated, and the user selects whether to enter the low power consumption mode according to the prompt message, that is, continuously performs step 103, and if the user selects no, stops the current process and continuously plays the video. Optionally, after the user selects no and closes the prompt message, the pop-up may be performed every other preset time period, for example, 5 minutes, so as to continue to remind the user.
And 103, reducing the priority of the target application program associated with the video, wherein the electronic equipment comprises a plurality of application programs, and the electronic equipment schedules equipment resources according to the priority corresponding to the application programs when the application programs are operated.
The priority of the application program is associated with device resource scheduling of the electronic device. The electronic device is preset with a plurality of priority groups, and the system has different limits on the scheduling of device resources according to the application programs in each priority group.
For example, the electronic device is an android 9.0-based device, and the android 9.0 is newly added with an application standby grouping function, so that the system restricts an application from calling device resources such as a CPU or a network according to the use condition of the application by a user, where the application standby grouping function includes the following groups, respectively: active (being used), working (being used with a high frequency), frequently used (often but not daily), infrequent, and occasional, where applications in different groups call device resources with different priorities.
In an embodiment, the application program associated with the video is an application program used when the video is played, and when the application program is used to play the video, if the current remaining power is less than the preset power, the priority of the application program may be reduced, for example, the application program may be transferred from a common packet to a few packets, so as to limit the permission of the application program for calling the device resource.
In an embodiment, some more important applications may also be preset as the preset applications, and then before adjusting the priority, it is determined whether the application is the preset application, and if not, the step of decreasing the priority is continuously performed. Therefore, the priority setting of the application program which is important for the user can be prevented from being changed, and information data and the like are prevented from being missed. The preset application program may be added by the user or automatically set by the system, which is not further limited in this application.
And 104, acquiring and processing the video file, and playing the video according to the processed video file.
In one embodiment, the video file may be processed according to the habit of the user using the electronic device, and then the video may be played according to the processed video file. For example, a user watches more pictures in the process of using the electronic device, a video file can be converted into a picture, and then the picture is played; or the user can convert the video file into an audio file and then play the audio file if the user listens more music in the process of using the electronic equipment; for example, if a user watches more videos in the process of using the electronic device, the video file can be converted into a format which saves more electric quantity and played.
The method comprises the steps of acquiring a history record of the electronic equipment used by a user in a preset time period, then determining user preferences, and processing a video file according to the user preferences. The history of the user using the electronic device is to determine the preference of the user, so the history may be selected from the history in a longer period of time, for example, twenty days or thirty days, or may be set by the user, which is not further limited in this application.
As can be seen from the above, the video playing method provided in the embodiment of the present application can obtain the current remaining power of the electronic device when the electronic device plays a video, determine whether the remaining power is smaller than the preset power, and if so, reduce the priority of the target application program associated with the video, where the electronic device includes a plurality of application programs, and when the electronic device runs the application programs, the electronic device schedules device resources according to the priority corresponding to the application program, obtains a video file and processes the video file, and plays the video according to the processed video file. According to the embodiment of the application, when the electronic equipment plays the video, the priority of the application program corresponding to the video can be reduced, and the video file is played after being processed, so that the electric quantity consumption of the electronic equipment is reduced, and the cruising ability is improved.
The cleaning method of the present application will be further described below on the basis of the method described in the above embodiment. Referring to fig. 2, fig. 2 is another schematic flow chart of a video playing method according to an embodiment of the present application, where the video playing method includes:
For example, the usage frequency of all the applications of the electronic device in a preset time period is obtained, and the usage frequency may be an operation frequency or a start frequency of the applications.
In step 202, the priority of the application program is allocated according to the use frequency.
In one embodiment, an electronic device includes power management functionality that can prioritize its resource requests based on frequency of use or last time of use of an application. The priority grouping, a total of five groups, will be divided into one of five priority groupings by the system according to the usage of each application, and each grouping has different restrictions on the scheduling of device resources. The higher the application activity, i.e. the higher the frequency of use, the higher the priority of the packet, and accordingly the easier it is to acquire the device resources.
In one embodiment, the application priority packets may include 5, active, work, common, rarely, and infrequently used packets, respectively. Alternatively, applications that have not been used at the last time after installation may be divided into a special group of "never" and subject to very strict system constraints.
The initial power of the electronic device is known in advance, and the electronic device may consume a certain power by running a plurality of programs installed on the electronic device or using hardware, and the electronic device may obtain the remaining power of the electronic device according to a plurality of modes, for example: and directly taking the residual capacity of the power supply on the electronic equipment as the residual capacity of the electronic equipment.
In step 204, it is determined whether the remaining power is less than the predetermined power, and if so, step 205 is executed.
In the embodiment of the present application, a remaining power value is preset, after the current remaining power of the electronic device is obtained, the remaining power is compared with the preset power, and if the remaining power is smaller than the preset power, step 205 may be further performed to reduce power consumption of video playing.
And step 205, reducing the priority of the application program associated with the video, wherein the priority of the application program is associated with the equipment resource scheduling of the electronic equipment.
In an embodiment, the application program associated with the video is an application program used when the video is played, and when the application program is used to play the video, if the current remaining power is less than the preset power, the priority of the application program may be reduced, for example, the application program may be transferred from a common packet to a few packets, so as to limit the permission of the application program for calling the device resource.
In an embodiment, the priority of the application program may be reduced according to the current remaining power, for example, the preset power is 20%, if the current remaining power is 10% to 20%, the priority of the application program is reduced by one priority, and if the current remaining power is 0% to 10%, the priority of the application program is reduced by two priorities. I.e., reducing the priority of the application associated with the video, including:
determining a target priority corresponding to the application program according to the residual electric quantity;
adjusting the priority of the application to the target priority.
In one embodiment, the priority of the application program can be only adjusted down but not up. For example, as shown in fig. 3, fig. 3 is a schematic view of a scenario of a method for adjusting a priority of an application according to an embodiment of the present application. The electronic equipment comprises a first priority, a second priority and a third priority, wherein the first priority is higher than the second priority, the second priority is higher than the third priority, and the application programs are divided into the following priority according to the use frequency of the application programs: the application program a and the application program b belong to a first priority level, the application program c and the application program d belong to a second priority level, and the application program e and the application program f belong to a third priority level. When the electronic equipment plays the video, the used application program is the application program b, when the residual electric quantity of the electronic equipment is smaller than the preset electric quantity, the priority of the application program b is reduced from the first priority to the second priority, and the priorities of the other application programs are not changed. Therefore, the electronic equipment allocates the equipment resources to the electronic equipment according to the priority adjusted by the application program.
In an embodiment, the video file can be processed according to the preference habit of the user, for example, the user can watch more pictures in the process of using the electronic device, the video file can be converted into pictures, and then the pictures are played; or the user can convert the video file into an audio file and then play the audio file if the user listens more music in the process of using the electronic equipment; for example, if a user watches more videos in the process of using the electronic device, the video file can be converted into a format which saves more electric quantity and played. Therefore, the embodiment of the application can acquire the history record of the multimedia file played by the electronic device in the preset time period, wherein the multimedia file can include three types, namely a picture type, an audio type and a video type.
In an embodiment, the target multimedia form may be determined according to the usage time of the three multimedia forms in a preset time period, for example, in the last twenty days, the total time of the user watching pictures is 3 hours, the total time of the user listening to audio is 8 hours, and the total time of the user watching videos is 6 hours, the target multimedia form may be determined to be the audio form.
And 208, processing the video file according to the target multimedia form and playing the video according to the processed video file.
In an embodiment, when the target multimedia format is the picture format, the video file may be subjected to frame extraction for multiple times to obtain a picture set, and pictures in the picture set are played at preset time intervals. Specifically, the key frames in the video file, such as the frames in the movie showing the subtitles, may be determined first, then the key frames are extracted to obtain the picture set, and then the picture set is played in a slideshow manner, such as playing one picture every 5 seconds.
In an embodiment, when the target multimedia format is the audio format, the playing of the video stream of the video file may be stopped, the screen of the electronic device may be closed, and the audio stream of the video file may be played. For example, the decoding of the video data stream of the video file is prohibited, the decoding of the audio data stream of the video file is performed, the decoded audio data stream is output to the audio path, and when the output of the video data stream is closed, only the audio data stream is output, which may reduce the consumption of resources.
In an embodiment, when the target multimedia format is the video format, power saving processing may be performed on the video file, where the power saving processing includes at least one of reducing the video resolution, reducing the video frame number, and reducing screen brightness, and the video is played according to the video file after the power saving processing.
As can be seen from the above, the video playing method provided in the embodiment of the present application can obtain the use frequency of an application program in an electronic device, allocate the priority of the application program according to the use frequency, obtain the current remaining power of the electronic device when the electronic device plays a video, determine whether the remaining power is smaller than a preset power, and if so, reduce the priority of the application program associated with the video, where the priority of the application program is associated with device resource scheduling of the electronic device, obtain a history record of the electronic device playing a multimedia file within a preset time period, where the multimedia file includes a plurality of multimedia forms, select a target multimedia form from the plurality of multimedia forms according to the history record, process the video file according to the target multimedia form, and play the video according to the processed video file. According to the embodiment of the application, when the electronic equipment plays the video, the priority of the application program corresponding to the video can be reduced, and the video file is played after being processed, so that the electric quantity consumption of the electronic equipment is reduced, and the cruising ability is improved.
