In this embodiment, the low-power video processing method for the mobile terminal is applied to a video server provided with a video scheduler.
Referring to fig. 3, fig. 3 is a schematic view of an application scenario in an embodiment of the present invention; in the existing video service system, an edge server is added, and the edge server is responsible for providing a low-power transcoding service for video streams for mobile terminals within the range of one or more base stations, wherein a mobile terminal within the service range of an edge server is defined as a VC (Virtual Cluster). The edge server has a low-power-consumption video transcoding function, and reduces the energy consumption of the video image on a display screen of the mobile terminal by converting or adjusting the color, brightness or contrast of the video image without influencing the watching experience (or influencing insignificantly).
Meanwhile, a video scheduler (LPVS scheduler) is arranged in the video server and is used for periodically collecting information of the mobile terminal (electric quantity information of a mobile terminal battery, mobile terminal display screen model information, CPU utilization rate of the mobile terminal and the like), and on the premise that the watching experience of a user is not obviously influenced, the users belonging to different virtual clusters are strategically selected within the capability bearing range of corresponding edge servers (calculation and storage) to carry out low-power video transcoding service, so that the probability that the whole user group abandons to watch videos is maximally reduced in the period, and the time for watching the videos is prolonged.
In this embodiment, the low-power video processing method for the mobile terminal includes:
step S100, acquiring electric quantity information and equipment information of each mobile terminal at intervals of preset duration based on the latest terminal equipment information of a plurality of mobile terminals playing video information currently;
in this embodiment, the plurality of mobile terminals currently playing the video information refer to mobile terminals that need to acquire the played video information from the video server. In the embodiment, the information of the terminal equipment comprises the current electric quantity information and the equipment information of the mobile terminal, and the equipment information comprises the model information of a display screen of the mobile terminal, the CPU utilization rate of the mobile terminal and the like. The preset time interval is smaller than the preset time length, so that the video server receives the terminal device information of the mobile terminal at least once within the preset time length, for example, the preset time length is 30 seconds, and the preset time interval is 2 seconds.
In this embodiment, the video server periodically obtains the power information and the device information of each mobile terminal at intervals of a preset duration, and specifically, analyzes information of the latest terminal device of a plurality of mobile terminals currently playing video information to obtain the power information and the device information of each mobile terminal, where the device information includes model information of a display screen of the mobile terminal, CPU utilization of the mobile terminal, and the like; the latest terminal device information is the terminal device information with the shortest time difference between the receiving time and the current time in the terminal device information of the mobile terminal currently stored by the video server.
Step S200, based on the electric quantity information and the equipment information, determining a target mobile terminal which meets a video transcoding condition in each mobile terminal through the video scheduler;
in this embodiment, when the power information and the device information of each mobile terminal are obtained, a video scheduler of the video server determines a target mobile terminal meeting a video transcoding condition in each mobile terminal according to the power information and the device information, specifically, a video to be played with a preset duration corresponding to each mobile terminal is obtained first, each video to be played is a video segment that needs to be played in a next playing period of each mobile terminal, the video to be played, the power information and the device information are used as inputs of an optimized scheduling algorithm, an output result is whether video transcoding needs to be provided in the next playing period of each mobile terminal to perform low-power video playing, for example, the output result includes 0 and 1, where 0 is no video transcoding need to be provided, 1 is video transcoding needs to be provided, and then the target mobile terminal meeting the video transcoding condition in each mobile terminal is determined according to the output result, namely, the mobile terminal corresponding to the output result 1 is the target mobile terminal.
And step S300, based on the target mobile terminals, sending videos to be played with preset time length corresponding to each mobile terminal to an edge server, wherein the edge server performs low-power-consumption transcoding on the videos to be played of the targets corresponding to the target mobile terminals in the videos to be played, and sends the transcoded videos to be played of the targets to the target mobile terminals.
In this embodiment, after the target mobile terminal is determined, the video to be played with the preset duration corresponding to each mobile terminal is sent to the edge server based on the target mobile terminal, for example, marking the video of the target mobile terminal in the video to be played, sending the marked video to be played to an edge server, or, the video to be played and the video identifier corresponding to the target mobile terminal are sent to the edge server, and after the edge server receives the video to be played, performing low-power transcoding on a target video to be played corresponding to a target mobile terminal in the video to be played, reducing the energy consumption of the video image on a display screen of the mobile terminal by converting or adjusting the color, brightness or contrast of the video image, and sending the transcoded target video to be played to the target mobile terminal, and simultaneously, directly sending the video to be played of other terminals except the target mobile terminal to the corresponding mobile terminals.
In the embodiment, the video information played by the mobile terminal with higher video watching abandon probability acceleration rate is transcoded into the low-power-consumption video (the target video to be played), so that the energy consumption of the mobile terminal is reduced to slow down the enhancement of the anxiety of the user and the reduction of the video experience, the probability of the user abandoning watching the video is reduced, the duration of the user watching the video is increased, and the user retention rate and the stickiness are improved for the video service provider.
The edge server assists in low-power-consumption video transcoding, so that the calculation and storage expenses of video transcoding of the video server are reduced, and meanwhile, low-power-consumption video service is provided for the mobile terminal with low electric quantity, and a video service provider is helped to reduce user loss. Meanwhile, because the existing low-power-consumption video transcoding function is usually performed on the mobile device side, part of energy consumption which can be saved originally can be offset in the practical application process, and even the device energy consumption (such as the situations of high video resolution and complex transcoding calculation) can be increased.
It should be noted that, in general, for a mobile terminal with an electric quantity greater than a preset value, a user of the mobile terminal does not have a "low-battery anxiety," and therefore, the step S200 may be optimized, specifically, the step S200 includes: and determining low-power mobile terminals with the residual power less than a preset value in each mobile terminal based on the power information, determining target mobile terminals meeting video transcoding conditions in each low-power mobile terminal through the video scheduler based on the power information and the equipment information, and reducing the data volume needing to be processed by the video scheduler and improving the processing efficiency by eliminating the mobile terminals basically without anxiety feeling ('low power anxiety') in each mobile terminal. The preset value can be set reasonably, for example, the preset value is 50%, 60%, etc.
Further, in an embodiment, the step S200 includes:
and running an optimized scheduling algorithm through the video scheduler based on the electric quantity information and the equipment information to determine target mobile terminals meeting video transcoding conditions in all the mobile terminals.
In this embodiment, when the electric quantity information and the device information are obtained, the video scheduler runs the optimized scheduling algorithm to obtain an optimized result corresponding to the optimized scheduling algorithm, and determines a target mobile terminal meeting the video transcoding condition in each mobile terminal based on the optimized result.
According to the low-power-consumption video processing method for the mobile terminal, the electric quantity information and the equipment information of each mobile terminal are obtained through the latest video requests of a plurality of mobile terminals at intervals of preset duration based on the currently played video information; then, based on the electric quantity information and the equipment information, determining a target mobile terminal which meets a video transcoding condition in each mobile terminal through the video scheduler; and then based on the target mobile terminal, sending videos to be played with preset time duration corresponding to each mobile terminal to an edge server, wherein the edge server transcodes the videos to be played with low power consumption corresponding to the target mobile terminal in the videos to be played, sends the transcoded videos to be played with the target to the target mobile terminal, and transcodes video information played by the mobile terminal with high probability acceleration of abandoning and watching the videos by part of users into the videos with low power consumption (the videos to be played with the target), so that the energy consumption of the mobile terminal is reduced to slow down the enhancement of the anxiety of the users and the reduction of the video experience, thereby reducing the probability of abandoning and watching the videos by the users, increasing the time duration of watching the videos by the users, and improving the user retention rate and the viscosity for a video service provider.
Based on the first embodiment, a second embodiment of the low power consumption video processing method of the mobile terminal of the present invention is provided, in this embodiment, step S200 includes:
step S210, acquiring the probability increasing rate of the abandoned playing video corresponding to each mobile terminal through the electric quantity information and the probability curve of the abandoned playing video;
and step S220, solving an optimization problem of a video scheduler based on the probability increase rate of abandoning the playing of the video, so as to determine target mobile terminals meeting video transcoding conditions in each mobile terminal through the equipment information.
In this embodiment, the power information is the remaining power of the mobile terminal corresponding to each piece of device information, after the power information and the device information are obtained, a probability curve for abandoning playing the video is obtained, and the probability increase rate for abandoning playing the video corresponding to each mobile terminal is obtained through the power information and the probability curve for abandoning playing the video. Specifically, the probability increase rate of the abandoning and playing video corresponding to each mobile terminal can be determined and obtained through the slope corresponding to each power information in each probability curve, for example, the probability increase rate of the abandoning and playing video corresponding to the mobile terminal is the absolute value of the slope corresponding to the power information of the mobile terminal.
In this embodiment, after the probability increase rate of the forgoing playing video corresponding to each mobile terminal is obtained, based on the probability increase rate of the forgoing playing video, an optimization problem of a video scheduler is solved to determine a target mobile terminal satisfying a video transcoding condition in each mobile terminal through device information, specifically, the optimization problem of the video scheduler is solved through the probability increase rate of the forgoing playing video to obtain an optimization result, and the target mobile terminal is determined in each mobile terminal according to the optimization result and the device information to accurately obtain a mobile terminal to be optimized, so that the edge server performs low-power transcoding on a video to be played corresponding to the target mobile terminal.
