Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as set forth in the claims below.
Fig. 1 is a flow diagram illustrating a method of video capture, which may include the following steps, as shown in fig. 1, according to an example embodiment.
In step S110, a screenshot request for a video is acquired.
The screenshot request is an instruction command for screenshot of the video, which is generated by triggering of a screenshot operation of the user.
Specifically, the user may capture a screenshot of the entire display area of the video, or capture a screenshot of a specific area in the entire display area of the video.
In step S120, a screenshot command is generated according to the screenshot request.
The screenshot command comprises a graphic function and an input parameter thereof, and the screenshot image is restored by executing a plurality of graphic functions in the screenshot command according to the corresponding input parameter.
It can be understood that the screenshot operations performed by the user are different, the generated screenshot requests will be different, and further, the graphic functions and the input parameters thereof in the screenshot command will be different.
In different screenshot commands, certain differences exist between the graphic function and the input parameters of the graphic function.
In an exemplary embodiment, the graphics function is an API (Application Programming Interface) function, typically, a plurality of API functions are predefined in the DirectX and OpenG L systems, the graphics function in the screenshot instruction is one or more of the predefined API functions of the systems, and the input parameter is an input status parameter of each API function.
For example, FIG. 2 is a block diagram of a system shown in accordance with an exemplary embodiment. The input parameters of each API function include input state parameters of the API function, such as vertex buffer, index buffer, vertex attribute, rendering state, shader parameter buffer, and texture state.
In step S130, the screenshot command is saved, so that a corresponding screenshot is generated when the screenshot command is executed.
And generating a corresponding screenshot when the screenshot command is executed according to the screenshot command by storing the screenshot command.
The screenshot command may be stored in a cache of the terminal or may be stored in a memory of the terminal, which is not limited herein.
By the method, after the video is subjected to screenshot, only the generated screenshot instruction needs to be stored, all pixel data of the screenshot does not need to be stored, and the screenshot instruction is much smaller than the data volume of the image data, so that the data volume when the video screenshot is stored is greatly reduced on the premise of not influencing the image quality of the video screenshot.
Fig. 3 is a detailed description of step S130 in the video screenshot method shown in the corresponding embodiment of fig. 1, where step S130 in the video screenshot method may include the following steps:
in step S131, an executed instruction identical to the screenshot instruction is searched for from the instruction execution record.
The instruction execution record is a record for storing executed instructions executed in the historical screenshot operation.
If a graphic function and its input parameter in the screenshot command are identical to a certain executed command in the command execution record, it indicates that the graphic command is executed in the previous screenshot operation.
In step S132, index replacement is performed on the screenshot command according to the executed command.
The method has the advantages that the graphic functions executed in the historical screenshot operation in the screenshot command and the input parameters thereof are subjected to index replacement, so that the screenshot command is compressed and stored, and the data volume of the screenshot command is further reduced.
In the screenshot command, if the screenshot command is completely the same as the executed command in the command execution record, it indicates that the screenshot command is executed in the previous screenshot operation. Therefore, the screenshot command is subjected to index replacement, the screenshot command which is executed once does not need to be stored in a graphic function and input parameters thereof, and the graphic function and the input parameters thereof in different screenshot commands have strong repeatability, so that the data volume of the screenshot command is greatly reduced, and when the screenshot is displayed, all the screenshot commands are executed, all the image data of the video screenshot is restored, and the quality of the video screenshot is ensured.
Fig. 4 is a detailed description of step S132 in the video screenshot method shown in the corresponding embodiment of fig. 3, where step S132 may include the following steps:
in step S1321, an index instruction is generated from the call address of the executed instruction.
The call address of the executed instruction is an identification address of the executed instruction in the instruction execution record to which the call is made.
The call address may be a storage address of the executed instruction, an identification name of the executed instruction, or other types of identifications, where the identification type of the call address is not limited herein.
The index instruction is an index indication generated from the call address.
By indexing the instructions, the corresponding executed instruction can be uniquely located.
It should be noted that the index instruction is distinguished from the GPU virtual machine instruction.
In a specific exemplary embodiment, if the most significant MSB of an instruction is 1, then the instruction is a GPU virtual machine instruction; if the most significant MSB of an instruction is 0, the instruction is an index instruction.
In step S1322, the screenshot command is replaced with an index command.
Because the screenshot instruction which is the same as the executed instruction in the instruction execution record is executed once, the executed instruction in the instruction execution record is pointed by the index instruction, and when the screenshot instruction is executed again, the executed instruction in the instruction execution record pointed by the index instruction is executed, so that the instruction execution accuracy is ensured, graphic eucalyptus and input parameters thereof in the corresponding screenshot instruction do not need to be stored one by one, and the data volume of the screenshot instruction is further reduced.
Optionally, as shown in fig. 5, after step S130 in the embodiment corresponding to fig. 1, the video screenshot method may further include the following steps.
In step S210, the screenshot instruction is executed in the execution order.
It should be noted that, when displaying the image of the screenshot to the screenshot command, all the screenshot commands corresponding to the screenshot need to be executed.
And each screenshot instruction has a certain execution sequence, and when the screenshot instruction is executed, each screenshot instruction needs to be executed according to the execution sequence of the screenshot instruction.
The execution sequence is the execution sequence of all screenshot instructions in all screenshot instructions corresponding to the screenshot.
It should be noted that, in all screenshot commands generated according to one screenshot request, there may be a case that the same screenshot command is to be executed multiple times.
For example, the screenshot instructions generated according to the screenshot request P sequentially include screenshot instructions a1, a2, A3, a1 and A3, namely, the screenshot instructions a1 and A3 are all executed twice.
In different screenshot commands, the graphics function may be the same, but only the input parameters of the graphics function are different.
For example, in the screenshot command a1, the graphic function is b1, and the input parameter x1 of the graphic function b 1; in the screenshot command a2, the graphic function is b1, and the input parameter x2 of the graphic function b1 is used. It can be seen that the screenshot instruction a1 is the same as the graphical function in screenshot instruction a2, but only the input parameters of the graphical function are different.
In step S220, a corresponding screenshot is generated through execution of the screenshot instruction.
Through the input parameters of the graphic function, in the execution process of the screenshot command, the graphic API can direct the graphic hardware (GPU) to perform image rendering, generate and display the corresponding screenshot.
Optionally, as shown in fig. 6, the screenshot instruction includes a graphic instruction and an index instruction, and when the screenshot instruction is executed, step S210 may further include the following steps.
In step S211, it is determined whether the executed screenshot command is a graphics command, and if yes, step S212 is executed; if not (N), step S213 is executed.
When the screenshot command is a graphic command, the graphic command is not executed before, so that when the graphic command is executed, the graphic command is stored in the command execution record as an executed command, and further in the subsequent screenshot operation, the executed command in the command execution record is pointed by the index command without storing the graphic command in the form of a graphic function and an input parameter of the graphic function, so that the data volume of the screenshot command is greatly reduced, and the occupied space is saved.
When the screenshot instruction is an index instruction, the executed instruction pointed by the index instruction is indicated to have been executed once, so that the executed instruction pointed by the index instruction only needs to be executed again.
In step S212, the graphics instruction is executed and saved in the instruction execution record as an executed instruction.
In step S213, the executed instruction pointed to by the index instruction is acquired and executed.
By the method, when the screenshot command is subjected to image restoration of screenshot, whether the screenshot command is a graphic command or not is judged in advance, and when the graphic command is executed, the graphic command is stored in the command execution record in the form of the executed command, so that when the same graphic command appears in the screenshot command in the subsequent screenshot operation process, the graphic command only needs to be stored in the form of an index command, the data volume of the screenshot command is further reduced, and the occupied space during storage is saved.
The following is an embodiment of a system of the present invention, which may be used to implement the above-described embodiment of the video screenshot method. For details not disclosed in the embodiment of the system of the present invention, please refer to the embodiment of the video capture method of the present invention.
