Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
With the improvement of the hardware performance of the electronic device, more electronic devices can support video playing. For example, the electronic device may run a video playing client and then play a video requested from the network through the video playing client, or may run a web browser and then play the video through the web browser, or the electronic device may play a locally stored video file through video playing software.
When the video is generated, the generated video is compressed in order to reduce the occupation of storage space and facilitate transmission on the network, regardless of whether the video is played or stored locally. Accordingly, when the electronic device acquires the video, the video acquired first will also be the video after compression encoding, and in this case, the electronic device will perform video decoding on the video which has been compression encoded first.
Generally, as shown in fig. 1, an electronic device can perform video decoding by both hard decoding and soft decoding. The hard decoding refers to decoding using a non-CPU, such as a gpu (graphics Processing unit), a dedicated DSP, an FPGA, an ASIC chip, and the like. And soft decoding refers to decoding using a CPU.
Specifically, as shown in fig. 1, a Media frame acquires a Video file to be played through an API interface with a client or a web browser, and delivers the Video file to a Video Decode, where the Media frame is a multimedia frame in an operating system. And wherein the Video decoder is a Video decoder for decoding the Video data.
Whether hard decoding or soft decoding, after decoding the video data, the decoded video data is transmitted to the surface flunger, and is rendered and synthesized by the surface flunger, and then displayed on a screen. The Surface flunger is an independent Service, receives all the surfaces as input, calculates the position of each Surface in the final composite image according to parameters such as ZOrder, transparency, size and position, and then sends the position to HWcomposer or OpenGL to generate a final display Buffer, and then displays the final display Buffer on a specific display device.
The inventor finds that the visual enhancement process can be added in the hard decoding process or the soft decoding process, so that the video played subsequently has higher visual effect. For example, video may be edge-dried, exposure-adjusted, or sharpness-enhanced based on hqv (hollywood quality video) technology. In addition, the visual experience of the played video can be improved in other ways, for example, the color flamboyance degree is improved.
However, the inventors further found that the control of whether to visually enhance the played video still remains to be improved. Therefore, the video enhancement control method and device and the electronic equipment which can improve the control convenience and the intellectualization are provided.
The present disclosure will now be described with reference to specific embodiments.
Referring to fig. 2, a video enhancement control method provided by the present application is applied to an electronic device, and the method includes:
step S110: whether the electronic equipment is in a video playing state is detected.
In this application, the electronic device may identify whether the video playing status is currently in a video playing status in various ways.
As one mode, the step of detecting whether the electronic device is in a video playing state includes: detecting whether a set video playing application program runs in the electronic equipment; and if the set video playing application program is detected to be running, judging that the electronic equipment is in the video playing state. The electronic device may pre-establish a list of video playing applications, so as to record the video playing applications in the list. The list may be freely configured by a user of the electronic device, or may be determined according to a usage situation of a certain video playing application program.
For example, as shown in fig. 3, a plurality of applications and a corresponding state for each application are displayed in the interface shown in fig. 3. It is to be understood that if the status corresponding to the application is "off" as illustrated, it indicates that the application is removed or not added to the list, and if the status corresponding to the application is "on" as illustrated, it indicates that the application is added to the list. For example, for an application named "TX video", the corresponding status is "on", i.e. it means that "TX video" is present in the aforementioned list. For the application named "AQY video", the corresponding status is "off", which means that the application "AQY video" does not exist in the aforementioned list.
Furthermore, the electronic device may detect the usage frequency of each video playing application program, and if it is detected that the usage frequency of a certain video playing application program exceeds a set frequency, the video playing application program may be added to the aforementioned list, and the state corresponding to the name of the video playing application program in fig. 3 is configured to be "on".
In this case, the electronic device may first detect which application currently running in the foreground is, and then further detect whether the application currently running in the foreground is in the list, and if so, determine that the electronic device is currently in the video playing state. As one mode, if the electronic device is an Android operating system, the name of the application program currently running in the foreground may be obtained by executing a getreporting tasks method of the ActivityManager. In addition, the electronic device may further acquire a list of programs used by the user through the usagetstatsmanager, and identify a most recently used application program recorded in the list as a current foreground application. Moreover, the Android can monitor the change of the focus of the window through the barrier-free function of the Android, and the package name corresponding to the focus window is taken as the application program which runs in the foreground at the present time.
Alternatively, the electronic device may determine whether a video is being played by detecting a return value of the AudioManager class. In this case, the electronic device may first detect a return value of the AudioManager class to determine whether there is an audio output, and if so, further determine whether the electronic device is in a video playing state according to whether there is a video playing application running.
Furthermore, as another mode, the electronic device may further detect whether the electronic device is in the video playing state by detecting a touch state of the video playing key. For example, as shown in fig. 4, a play key 98 is displayed in the video play interface 99 shown in fig. 4, and the interface shown in fig. 4 is in a state where video play is paused. In this case, when the play key 98 is detected to be touched, it can be determined that the electronic device is currently in the video playing state. Correspondingly, if the electronic device is in the video playing state and the playing key 98 is detected to be touched again, it can be determined that the electronic device is in the video pause state, so that the visual enhancement is cancelled. In this way, in the process of performing visual enhancement, only the video being played can be visually enhanced, and the picture displayed when the playing is paused does not need to be visually enhanced, so that the enhancement efficiency is improved.
As one mode, the video enhancement control method provided by the present application may be executed by the aforementioned video playing application program, or may be executed by a program independent from the video playing application program in the electronic device. If the provided video enhancement control method can be executed by the video playing application program, the video enhancement control method can be executed by a sub-process included in the main process corresponding to the video playing application program in the running process, so as to avoid influencing other functions of the video playing application program in the process of executing the video enhancement method. If the video enhancement control method is executed by a program independent of the video playing application program in the electronic device, the video enhancement control method can be executed by another application program independent of the video playing application program.
Step S120: and if the electronic equipment is detected to be in the video playing state, detecting the state of a control, wherein the control is used for controlling the opening or closing of the visual enhancement.
Therein, it is understood that the electronic device may establish a variable and then use the variable value to identify the state of the control. For example, if the variable value is 0, it indicates that the control is in a state that characterizes turning off visual enhancement, and if the variable value is 1, it indicates that the control is in a state that characterizes turning on visual enhancement. Then in this case, the electronic device may detect the variable value to determine the state of the control after detecting that the electronic device is in the video playing state.
Alternatively, the variable values may be stored in a pre-established data table. In this case, after detecting that the electronic device is in the video playing state, the electronic device may obtain the variable value in a table lookup manner, and further determine the state of the control.
In addition, after a certain application program is installed in the electronic device, the storage location of the corresponding configuration file is relatively fixed, and as another way, the variable value may also be stored in the configuration file of the corresponding video playing application program. In this case, after detecting that the video playing application is installed and detecting that the installed video playing application is set as the set video playing application, the electronic device may search for a file in any txt format in a configuration folder of the video playing application, add a variable to the searched file in txt format, and use a value of the variable as the variable value. By the method, the state detection of the control can be realized by using the configuration file of the video playing application program under the condition that the file is not newly added, and the state of the control corresponding to a certain video playing application program can be well distinguished because the configuration file of the video playing application program is used.
In this case, in order to avoid an influence on the original function of the configuration file, as one way, a variable may be added to the configuration file in an annotated manner. For example, for a txt format file, where the content is annotated with character bits starting with "//" or "/". Then in this case, where the variable of the electronic device configuration is hqv, the content inserted into the txt file may be "// hqv ═ 1", i.e. the characterization turns on visual enhancement.
It should be noted that, after some application programs are updated or reinstalled, their corresponding configuration files may be modified or replaced by other files. In this case, if it is detected that the set video playing application program is updated or reinstalled, it may be detected whether there is a file in the previously selected txt format, and if so, it may be further detected whether the previously inserted variable may be read out from the previously selected txt corresponding to the updated or reinstalled video playing application program, and if the reading fails, the variable may be inserted again in the manner described above. And if detecting that the previously selected txt format file does not exist, reselecting the txt file.
The above will be described with reference to a specific application program.
If the electronic device detects that the video playing application named TX video is installed, it further detects whether the TX video is configured as the configured video playing application. If it is detected that the TX video is configured for the configured video playback application. The electronic device may further search for txt formatted files in the folder storing the TX video profile. After any search is performed for one name tx.txt, a piece of data is inserted into the tx.txt, where the data content is "// hqv ═ 1" to represent that the control corresponding to the TX video is in a state representing that the visual enhancement is turned on, and then, if it is detected that the control corresponding to the TX video is touched, the electronic device modifies the originally inserted content to "// hqv ═ 0" to represent that the control corresponding to the TX video is in a state representing that the visual enhancement is turned off. Then, after detecting that the TX video is updated or reinstalled, the electronic device detects whether there is a tx.txt file in the configuration file corresponding to the TX video, and if so, further detects whether the content of "// hqv ═ 1" or "// hqv ═ 1" can be read from the tx.txt, and if so, the configuration before the representation is still valid, and if not, the electronic device inserts "// hqv ═ 1" into the tx.txt by default. And if the electronic equipment finds that the txt file cannot be found, the electronic equipment can reselect a txt file.
It should be noted that, for each file of the selected storage variable corresponding to each video playing application program, the file may be stored in the electronic device in a data table manner, so that the electronic device may search the file.
It should be noted that the above txt format file and the variable values are exemplary, and the application is not limited in particular. The electronic device can be specifically set according to the format file which can be found. For example, the variable values may also be stored using a file in xml format.
One way, the control operates independently of the video playback application. Then step S120 may include detecting a state of a control independent of the preset video playback application.
Step S130: and if the state representation of the control is detected to start video enhancement, performing visual enhancement on the played video.
The electronic device can visually enhance the played video based on various ways in the present application. For example, the electronic device may perform visual enhancement according to attributes of the played video application. Wherein the attributes include sharpness and color information, etc.
As one way, the electronic device may extract a frame of target image from the played video as a basis for attribute determination. It will be appreciated that if an image is blurred, then it is blurred again and the high frequency components in the image do not change much. However, if the sharpness of the image itself is high, and the blurring process is performed once, the high-frequency component varies greatly. Then, as one mode, the electronic device may obtain a degraded image of the target image by performing a blurring process (e.g., a gaussian blurring process) on the target image once, and then determine the sharpness value according to the magnitude of the change by comparing the change of the adjacent pixel values of the image before the blurring process and the image after the blurring process. Then in this case the greater the variation, the higher the sharpness of the target image.
In addition, in addition to determining the sharpness of the target image by blurring the target image, the sharpness may be calculated in other manners. Alternatively, it can be calculated by the following calculation formula
D(f)＝∑y∑x|f(x+2，y)-f(x，y)|2
To determine sharpness. Wherein f (x, y) represents the gray value of the pixel point (x, y) corresponding to the image f, and D (f) is the image definition calculation result. Optionally, in the present application, f (x, y) may select a high-frequency component region in the live preview image.
In this case, if it is detected that the sharpness of the target image is lower than the set value, the video played back may be visually enhanced in sharpness.
Further, the color information may be defined by the degree of color shift in the present application. As one way, the electronic device may determine the current degree of color cast by the chromaticity distribution of the target image and the chromaticity average. As one way, when the electronic device detects that the chromaticity distribution of the target image is substantially a single peak value, or the distribution is more concentrated, and the chromaticity average value is larger than the set value, it is determined that the target image has color cast. And the color cast value can be determined and obtained as color information according to the pre-established correspondence between the average chromaticity value and the color cast.
Furthermore, the electronic device may determine which aspect of visual enhancement to perform according to the environment in which the electronic device is located, for example, whether to perform visual enhancement in brightness on the played video may be determined according to the intensity of the ambient light in which the electronic device is located.
It should be noted that, if the foreground of the electronic device simultaneously performs video playing by two application programs in a split screen manner, the electronic device may select one of the two application programs to perform visual enhancement, or perform visual enhancement on the video played by each of the two application programs displayed in the split screen manner. As a mode, if the electronic device is provided with the camera located on the same side of the screen, the area concerned by the current eyeball of the user can be collected by the camera, so that the video displayed on the interface of the application program closer to the concerned area can be visually enhanced when the electronic device displays the interfaces of the two application programs in a split screen manner.
According to the video enhancement control method, whether the electronic equipment is in the video playing state or not is detected, if the electronic equipment is detected to be in the video playing state, the state of the control is detected, the control is used for responding to touch operation control to start or close visual enhancement, and if the state representation of the control is detected to start the video enhancement, the visual enhancement is carried out on the played video. Therefore, in the video playing process, a user can start or close the visual enhancement of the played video by performing touch operation on the control, convenience is provided for the user to control whether the visual enhancement is performed, and the user experience is improved.
Referring to fig. 5, a video enhancement control method provided by the present application is applied to an electronic device, and the method includes:
step S210: whether the electronic equipment is in a video playing state is detected.
Step S220: and if the electronic equipment is detected to be in the video playing state, the control is displayed on a video playing interface of the electronic equipment in a stacking mode, and the control is used for controlling the opening or closing of the visual enhancement.
As shown in fig. 6, if the electronic device detects that the electronic device is in the video playing state, a control 97 is displayed in a floating manner on the illustrated video playing interface 99. Wherein, the user can make the control 97 switch before representing the two states of turning on or turning off the visual enhancement by touching the control 97. By one approach, after the electronic device is displaying the control 97, the user can slide the control to move the control out of the video playback interface 99. For example, as shown in fig. 7, when the control shown in fig. 6 is slid upward in fig. 6, the control 97 is slid upward, and after the sliding is completed, the control is converted into the mark 96 shown in fig. 7. In this case, if the user slides the flag 96 downward as shown in fig. 7, the control 97 may be triggered to again be displayed in the style shown in fig. 6.
In addition, the control 97 may be slid in other directions in addition to the upward direction shown in fig. 6. For example, as shown in fig. 8, if the control 97 is slid toward the left side as shown in fig. 6, the converted identifier 96 will correspondingly appear on the left side of the video playing interface.
The control can be displayed on the video playing interface of the electronic device in a stacking manner at any time in a plurality of manners.
As one way, when using the electronic device, the user can log in through the user account so that the electronic device can distinguish different users. Then in this case, the electronic device may determine whether to display the control by the rating of the user account logged in. For example, the user account levels can be divided into one level, two levels and three levels from low to high, and the user accounts above the two levels can be set for visual enhancement. The electronic device may further detect the level of the currently logged-in user account after detecting that the electronic device is in the video playing state, and if detecting that the level of the currently logged-in user account is at two or more levels, the electronic device may display the control in a stacked manner on the video playing interface of the electronic device. And if the electronic equipment detects that the level of the currently logged-in user account is lower than the second level, the electronic equipment can display prompt information so as to prompt the user to upgrade the account and then perform visual enhancement.
It should be noted that the aforementioned account may be an account for logging in an operating system of the electronic device, or an account of a video playing application program that performs video playing specifically.
As a mode, the electronic device detects a change frequency of a continuous multi-frame image included in a video played by the video playing interface; and if the change frequency is greater than the set frequency, the control is displayed on a video playing interface of the electronic equipment in a stacking mode.
Therein, it is understood that the played video includes a plurality of frames of images. The content of the played video has different frequency of change of the corresponding content. For example, in the case where the played video is a video of a tv show or a movie, since the frequency of change of pictures in the video of the tv show or the movie is relatively high, in this case, the user more desires a better visual experience. For other video scenes, such as a knowledge explanation video or a class video, the picture is kept in the same state for a long time, but the corresponding audio data is changed differently. For example, in some video scenes of courses, a picture is fixed on a PPT page for a long time, and the corresponding representation changes continuously the audio explaining the contents of the PPT page. Then in this case the user is more concerned about the content being taught and the requirements for the visual experience are not too high.
Based on the above situation, as one way, the continuous multi-frame images included in the played video are obtained, the content features of the continuous multi-frame images are obtained, and based on the content features, the change frequency of the picture content represented by the played video is obtained.
As one approach, the content characteristics of the image may be determined by obtaining a gray-scale average. In this way, the electronic device may obtain a gray-scale average value of each of the consecutive multi-frame images, and obtain a content feature of each of the consecutive multi-frame images based on the gray-scale average value.
The content characteristics of the continuous multi-frame images obtained based on the average gray level value mentioned above will be described below.
The image may first be reduced to a size of 8x8 for a total of 64 pixels. The effect of this step is to remove the difference of various picture sizes and picture proportions and only keep basic information such as structure, light and shade. And converting the reduced picture into a 64-level gray picture. The average value of the gray levels of all the pixels in the picture is calculated. The gray level of each pixel is compared with the average value, and if the gray level is greater than or equal to the average value, the average value is 1, and if the gray level is less than the average value, the average value is 0. The comparison results from the previous step are combined to form a 64-bit binary integer, which is the fingerprint of the image. After the fingerprints of the images are obtained, the fingerprints of different images can be compared, and the number of different 64 bits is calculated, if the number of different data bits is not more than 5, the two images are very similar, and if the number of different data bits is more than 10, the two images are two different images. If the dissimilarity degree is added by 1 after n images are continuously detected and collected and two adjacent images are detected to be dissimilar, the dissimilarity degree obtained after the n images are compared is divided by the n, and the obtained value is the change frequency.
In this case, in order to more flexibly meet the actual requirements of the current user, if it is detected that the change frequency is greater than the set frequency, that is, the currently played video is represented as a video of a tv show or a movie, the currently played video may be displayed on the video playing interface of the electronic device, and the control may be displayed in an overlapped manner, so as to remind the user that the electronic device may further perform visual enhancement, thereby improving the visual experience of playing the video.
In addition, as another mode, the electronic device may detect a resolution of a video played by the video playing interface; and if the resolution of the video played by the video playing interface is the set resolution, the control is displayed on the video playing interface of the electronic equipment in a stacking mode.
It can be understood that when the electronic device plays videos with different resolutions, the presented definition may be different, and as the resolution is improved, the video played by the electronic device may be clearer. Then in one case, the set resolution is the highest resolution supported by the video played by the video playback interface.
It should be noted that, when the electronic device plays the video, the resolution of the played video is affected by the resolution that can be supported by the played video itself and the resolution that is supported by the electronic device itself. For example, if the resolution of the video itself is from low to high, standard definition, high definition, and super definition, and the resolution supported by the electronic device is also from low to high, standard definition, high definition, and super definition. If it is detected that the highest resolution supported by the electronic device is high definition, even if the resolution of the played video supports the super-definition resolution, the highest resolution supported by the played video is still high definition.
Furthermore, if the highest resolution supported by the played video is lower than the resolution supported by the electronic device, in this case, even if the user uses the electronic device to play the video, the highest resolution of the played video is still the highest resolution supported by the played video. In order to facilitate reminding the user of the visual experience of the played video, the control may be displayed on the video playing interface of the electronic device in an overlapped manner when it is detected that the highest resolution supported by the played video is lower than the highest resolution supported by the electronic device, so that the user can trigger the electronic device to perform visual enhancement through the control, and the played video may exhibit a better playing effect than the playing effect corresponding to the highest resolution that the user can support.
For example, as shown in fig. 9, in the diagram shown in fig. 9, a definition switching control 95 is shown, and after the user clicks the definition switching control 95, as shown in fig. 10, a definition alternative control 94 may be displayed, and a definition that can be selected is displayed in the definition alternative control 94, for example, as shown in fig. 10, the highest resolution supported by the played video is super-definition, in this case, if the highest resolution supported by the electronic device is super-definition or even in a 4K model higher than the super-definition, a control 97 may be displayed on the interface. Therefore, under the condition that the played video is played at the highest resolution ratio which can be supported by the video, after the control is displayed, the user can trigger the control to be in the state of starting visual enhancement, so that the electronic equipment can perform visual enhancement on the played video, and the played video can show a better playing effect than the playing effect corresponding to the highest resolution ratio which can be supported by the electronic equipment.
It can be understood that the video playing application program is playing the video on line, and then the data of the played video is obtained from the network in real time during the playing of the video on line. While the size of the storage space occupied by each of the videos for different resolutions may be different. For example, for the same video content, the video content in standard definition mode may occupy 200MB of storage space, while the video content in high definition mode may occupy 700MB of storage space. The same is true in the transmission process, and for the video content with higher resolution, the network bandwidth occupied by the transmission is larger.
In this case, optionally, the electronic device may decrease the resolution of the played video after detecting that the resolution of the video played by the video playing interface is the set resolution and detecting that the network quality of the network to which the electronic device is connected is lower than the set condition; and displaying the control on a video playing interface of the electronic equipment in a stacking manner.
The electronic device may detect the current network quality in various ways. For example, the electronic device may evaluate the quality of the network by the retransmission rate of the network.
It should be noted that, if the electronic device is connected to the network based on the TCP protocol, the electronic device uses a sliding window to manage the basic data transceiving process, and at the same time, ensures effective and reliable transmission of the data stream, so that the sending rate is not significantly faster than the receiving rate. And if the electronic equipment does not receive the confirmation information before the timer is overtime, the electronic equipment judges that retransmission is overtime, and automatically retransmits the data which is transmitted overtime before the electronic equipment.
Moreover, if the electronic device is playing the video, if the electronic device is stuck in the playing process for multiple times, it means that the electronic device is stuck in the decoding process of the video to be played, or the electronic device receives the network data, and the user experience is poor. The electronic device may further evaluate the quality of the network by detecting the number of times of the video playing process within the preset time period.
For example, if the electronic device plays a video in an ultra-definition mode, and the electronic device is dragged to detect that the network quality is lower than the set condition in the above manner during the video playing, the ratio of the played video is reduced to a high-definition mode, and in this case, the control may be displayed on the video playing interface of the electronic device in a stacked manner, so that the user may trigger the visual enhancement of the video played in the high-definition mode through the displayed control, and further the electronic device may play the video in the high-definition mode, but may exhibit a better visual effect than the high-definition mode.
It should be noted that, in the process of performing the visual enhancement, the electronic device may increase the consumption of the computing resources of the CPU or the GPU, and if the electronic device detects that the network quality is not lower than the set condition, the electronic device may prompt the user whether to switch to a higher resolution, and prompt the user whether to turn off the visual enhancement, so that after the network state is restored to be good, the consumption of the computing resources of the CPU or the GPU is reduced.
Therefore, the electronic equipment can be guaranteed to play videos smoothly under the condition of poor network state, and the playing effect better than that of the resolution ratio of smooth playing supported by the current network state can be displayed.

Step S240: and if the electronic equipment is detected to be in the video playing state, detecting the state of a control.
Step S250: and if the state representation of the control is detected to start video enhancement, performing visual enhancement on the played video.

Therefore, in the video playing process, a user can start or close the visual enhancement of the played video by performing touch operation on the control, convenience is provided for the user to control whether the visual enhancement is performed, and the user experience is improved.
