[0002] In existing technologies, since GPU rendering on the display path is an asynchronous pipeline behavior, the performance of rendering and compositing is affected by factors such as the different content being rendered and the current Android system load. Therefore, the calculation of display frame rate is not entirely accurate. At the same time, the frame rate statistics simply show how many frames are in one second, without refining the distribution and fluctuation of the frame rate within one second, resulting in a low level of refinement in display frame rate. Summary of the Invention

To this end, this invention proposes a frame rate processing method, apparatus, device, and medium based on the Android system, which can statistically display the frame start time and frame rate within each layer window period in real time, thereby improving the fineness of the displayed frame rate.

[0049] This invention provides a frame rate processing method based on the Android system, applied in a display frame rate acquisition device. The display frame rate acquisition device includes a preprocessing module and a detection module, which are connected. The preprocessing module is equipped with a display manager and a graphics composition manager. The method includes: the preprocessing module identifying the version information of the current Android system; inputting input parameters into the preprocessing module to parse the input parameters and obtain the first layer of the Android system; inputting the version information and the first layer into the display manager to adapt to different graphics composition managers of the Android system according to the version information and the first layer, thereby obtaining the layer information of the Android system; inputting the period information and layer information of the input parameters into the detection module to obtain the frame information of a specified or all first layers; the detection module obtaining the cumulative frame count and time elapsed based on the frame information, and calculating the frame rate based on the cumulative frame count and time elapsed; and the detection module obtaining multiple first timestamps of the frame rate and organizing the multiple first timestamps into a frame rate distribution curve. According to the technical solution of this embodiment, the frame rate is counted in the form of system layers, while distinguishing between display and drawing arrays. The time point when the frame rate is finally displayed on the screen is used as the frame number representative. The first timestamp of each layer is parsed in the form of multiple layers. The frame rate is displayed in a time-counting and counting display method. It also supports interval statistics and dynamic real-time frame rate, and generates a frame rate distribution curve to realize the analysis and positioning of frame number and security and confidentiality measures.

[0050] The control method of the present invention will be further described below with reference to the accompanying drawings.

[0051] Reference Figure 1 , Figure 1 A flowchart of a frame rate processing method based on the Android system provided in this embodiment of the invention. The frame rate processing method based on the Android system includes, but is not limited to, the following steps:

[0052] Step S11: The preprocessing module identifies the version information of the current Android system;

[0053] It should be noted that when the preprocessing module obtains the Android system version information, it adjusts the frame rate processing strategy of the display frame rate acquisition device according to the characteristics and limitations of the version information. When the display frame rate acquisition device encounters frame rate-related problems, it corrects and adjusts them using the Android system version information.

[0054] Step S12: Input parameters are input into the preprocessing module so that the preprocessing module can parse the input parameters and obtain multiple first layers of the Android system;

[0055] It should be noted that the preprocessing module parses the input parameters, and the display frame rate acquisition device determines whether to detect a single layer or the entire system layer based on the input parameters, and sets the window period to be detected and whether the detection information is output to the terminal or saved to a file.

[0056] Furthermore, when the display frame rate acquisition device is running, it detects, waits, reads, and parses the output parameters, and sets them according to the parsed input parameters; when the display frame rate acquisition device does not acquire input parameters, it uses the default values ​​to process the Android system.

[0057] Step S13: Input the version information and multiple first layers into the display manager so that the display manager can adapt to the different graphics composition managers of the Android system according to the version information and the first layers, and obtain the layer information of the Android system.

[0058] It should be noted that the display manager uses version information and multiple first layers to enable the preprocessing module to adapt to different graphics composition managers in the Android system, so that the correct layer information can be extracted according to the input parameters. The layer information includes, but is not limited to, the layer name and the layer order value, which are used to identify the actual upper and lower layer positions of multiple first layers.

[0059] Step S14: Input parameters, periodic information and layer information are input to the detection module so that the detection module can obtain frame information of a specified or all first layers;

[0060] It should be noted that the display frame rate acquisition device can acquire or specify the frame information of all layers according to the input information and the recorded layer information, based on the periodic information. By precisely controlling the frame rate of the first layer and the system layer and the actual frame rate based on the input information, it reduces image tearing and layer misalignment caused by layer frame rate mismatch. In addition, by acquiring or specifying the frame information of all first layers, it can effectively reduce the time and resource consumption required for the system to process layers while ensuring image clarity. Furthermore, the time interval before and after acquiring frame information is positively correlated with the actual time interval of the Android system display device.

[0061] In step S15, the detection module calculates the statistical frame rate and real-time frame rate based on the frame information.

[0062] It should be noted that by calculating and analyzing the frame rate and real-time frame rate, performance bottlenecks in the Android system can be identified and optimized in a timely manner, ensuring smooth playback on Android display devices, and allocating computing resources reasonably to avoid latency and stuttering.

[0063] It should be noted that by accurately obtaining the actual display frame rate used on the display device, and utilizing the time point of the present / draw fence singal in the asynchronous pipeline of the graphics buffer as the precise moment for statistical drawing / display frame rate (i.e., real-time frame rate), the display frame rate is defined and detected separately by layer (i.e., statistical frame rate). By hierarchically decomposing the application drawing-compositing series of actions in the form of layers from the display perspective, the focus is on the display frame rate seen on the screen by the end user, while also being able to see the actual drawn frame rate, thereby enabling frame count analysis and positioning, as well as security and confidentiality measures.

[0064] Additionally, in one embodiment, reference is made to Figure 2 ,exist Figure 1 Step S14 of the illustrated embodiment also includes, but is not limited to, the following steps:

[0065] Step S21: The frame information acquisition unit acquires the frame start time, timing count, and frame arrival time of the layer information;

[0066] In step S22, the frame rate calculation unit calculates the statistical frame rate and real-time frame rate of the first layer based on the period information, frame start time, timing count, and the time when the frame arrives at the display device.

[0067] It should be noted that, based on the input parameters and periodic information, the frame information of all layers is obtained or specified. Since the Linux sleep interval has errors due to scheduling wake-up, it affects the accuracy of frame rate statistics. Therefore, the time interval for obtaining frame information needs to take into account the time interval between the screen display frame rate and the real-time drawing frame rate. By obtaining the frame start time, timer count, the time point when the frame arrives at the display device, the time point when the frame is drawn, the number of times it is displayed, and the interval duration, the statistical frame rate and real-time frame rate are calculated according to actual needs.

[0068] Furthermore, based on the target layer in the preparation stage, the period information is obtained through dumpsys SurfaceFlinger --latency, and the layer frame information is parsed to obtain the frame start time within the period, as well as the present fence signal time marker actualPresentTime for each subsequent frame, count the number of present frames, the draw fence signal time marker frameReadyTime (i.e., timing count), and the time point when the frame arrives at the display device, count the number of frames drawn, and complete the acquisition of the first layer frame information.

[0069] Additionally, in one embodiment, reference is made to Figure 3 ,exist Figure 2 Step S22 of the illustrated embodiment also includes, but is not limited to, the following steps:

[0070] Step S31: Calculate the statistical frame rate based on the ratio of the number of displays to the interval duration;

[0071] Step S32: Calculate the real-time frame rate based on the ratio of the frame start time to the frame arrival time on the display device.

[0072] It should be noted that the statistical frame rate is the actual duration of frame information within one cycle, where frame rate = number of displays / interval duration; the real-time frame rate is the timer starting from the first frame in one cycle until the timer ends at the last frame in the cycle, where real-time frame rate = number of frames / duration. By calculating the statistical frame rate and the real-time frame rate, the smoothness changes of video or animation in the Android system are reflected. The calculated statistical frame rate and real-time frame rate are then organized into a frame rate distribution curve. The stability of the frame rate distribution curve is used to determine whether the current performance bottleneck is in the compositing stage, thereby ensuring the analysis and localization of frame rate.

[0073] Additionally, in one embodiment, reference is made to Figure 4 ,exist Figure 1 Following step S16 in the illustrated embodiment, the following steps are included, but are not limited to:

[0074] Step S41: Obtain the first timestamp of the statistical frame rate, and organize multiple first timestamps into a frame rate distribution curve;

[0075] Step S42: The security management module obtains the encryption status of the first layer and the frame rate distribution curve. The first layer and the frame rate distribution curve are both input into the security management module in the form of a script.

[0076] Step S43: When the first layer and frame rate distribution curve are in an unencrypted state, they are directly pushed to the target device;

[0077] Step S44: When the first layer and frame rate distribution curve are in an encrypted state, obtain root privileges for the target device. The first layer and frame rate distribution curve are input into the target device according to the root privileges, so that the target device's development toolkit can perform operations on the first layer and frame rate distribution curve.

[0078] It should be noted that both the preprocessing module's processing method and the detection module's detection method exist in the form of scripts. When the first layer and frame rate distribution curve of the display frame rate acquisition device are in an unencrypted state, they can be pushed to the target device. The target device can run normally regardless of whether it has root privileges, thus enhancing versatility. Furthermore, when the first layer and frame rate distribution curve are in an encrypted state, the security management module encrypts and compresses them (gzexe) into plaintext, and then integrates them into the Android system SDK. The security management module can only run normally on the target device's ADB terminal to acquire the frame rate if it has root privileges, thus ensuring security and confidentiality.

[0079] Additionally, in one embodiment, reference is made to Figure 5 ,exist Figure 1 Step S14 of the illustrated embodiment also includes, but is not limited to, the following steps:

[0080] Step S51: Obtain the second layer carrying the refresh display from the first layer, and the second timestamp displayed on the device screen according to the period information;

[0081] Step S52: Obtain the layer name and layer order value of the second layer;

[0082] In step S53, the display manager extracts the second layer based on the layer name and layer order value, and records the second timestamp.

[0083] It should be noted that by obtaining the second layer in the first layer that carries the information about the refreshed display, as well as the new display values ​​of the display device within a certain period of time and the second timestamp information of the completed drawing, and by pre-acquiring and storing the layer name and order value, the Android system can quickly locate and operate on specific layers, reducing the search time in multiple first layers. Furthermore, using a unique layer name and order value can ensure accurate referencing and operation of the correct layer. In addition, the second timestamp of the display device is displayed with periodic information. By recording the second timestamp of accessing or modifying the layer, the usage status of the layer can be provided.

[0084] Furthermore, the preprocessing module completes the adaptation of layer information in different display managers of the Android system version. The layer information includes the layer name and the layer order value. Based on the layer name and the layer order value, the second layer carrying the refresh display is extracted, thereby completing the matching of the second timestamp with the second layer.

[0085] Additionally, in one embodiment, reference is made to Figure 6 ,exist Figure 2 Following step S22 in the illustrated embodiment, the following steps are included, but are not limited to:

[0086] Step S61: Obtain the layer to be updated in the first layer or specify a single layer;

[0087] Step S62: Based on the period information, determine whether to calculate the statistical frame rate or the real-time frame rate.

[0088] Step S63: Obtain the first output value of the statistical frame rate and the second output value of the real-time frame rate, and save the first output value or the second output value to a file or output it to the terminal.

[0089] It should be noted that, based on different input parameters, all layers to be updated in the first layer are obtained, or the frame rate of a single layer is specified. Depending on the detection period, it is determined whether to obtain statistical frame rate or real-time frame rate. When obtaining statistical frame rate, the first output value of statistical frame rate is obtained; when obtaining real-time frame rate, the second output value of real-time frame rate is obtained. After confirming the first and / or second output values, it is determined whether to save the first and / or second output values ​​to a file or output them to the terminal device.

[0090] Furthermore, the display frame rate acquisition device detects, waits, reads, and parses the user's input parameters, and then sets the above options according to the parsed input parameters. If there is no additional input, the default value is used.

[0091] Additionally, in one embodiment, reference is made to Figure 7 ,exist Figure 1 Following step S14 in the illustrated embodiment, the following steps are included, but are not limited to:

[0092] Step S71: Determine the frame buffer and image storage area of ​​the first layer based on the frame information. The frame buffer is set with multiple Fence signal timestamps.

[0093] Step S72: When the display device retrieves the image storage area, the image storage area of ​​the first layer is updated to the current Fence signal timestamp time according to the frame rate of the screen displayed in front of the display device.

[0094] It should be noted that when the display frame rate acquisition device captures the actual frame rate displayed by the device, it determines the frame buffer and image storage area of ​​the first layer based on the frame information, as well as the multiple Fencesignal timestamps set in the frame buffer, and then updates the Fence signal timestamp. Specifically, the display frame rate acquisition device acquires the Fence signal timestamp of the display buffer, and only updates the Fence signal timestamp when that frame of the image buffer is finally to be used by the LCD screen.
