Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the following detailed description of specific embodiments thereof is given with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the matters related to the present application are shown in the accompanying drawings. Before discussing exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently, or at the same time. Furthermore, the order of the operations may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, and the like.
The desktop screen capturing method based on window filtering aims at creating a main process, creating a sub-process by using the main process to perform desktop screen capturing operation, and re-executing the desktop screen capturing operation according to the abnormal information of the sub-process when the screen capturing is abnormal, so that the stability and the reliability of the desktop screen capturing are improved.
For the related Magnification screen capturing scheme, when the desktop screen capturing operation is performed, a plurality of processes need to be created to execute the screen capturing operation, and in the process of executing the screen capturing operation and the window filtering operation by the plurality of processes, as the related interfaces are not adapted, the interface has the condition of call failure in the calling process, so that the abnormal condition of the desktop screen capturing operation is caused. Based on the method, the desktop screen capturing method based on window filtering is provided, and the problem of abnormal screen capturing caused by window filtering during desktop screen capturing is solved.
Embodiment one:
fig. 1 shows a flowchart of a desktop screen capturing method based on window filtering according to an embodiment of the present application, where the desktop screen capturing method based on window filtering according to the embodiment may be implemented by a desktop screen capturing device based on window filtering, where the desktop screen capturing device based on window filtering may be implemented by software and/or hardware, and the desktop screen capturing device based on window filtering may be formed by two or more physical entities or may be formed by one physical entity. Generally, the desktop screen capturing device based on window filtering can be a terminal device such as a computer, an intelligent large board, a tablet, a mobile phone and the like.
The following describes the desktop screen capturing device based on window filtering as a main body for executing the desktop screen capturing method based on window filtering. Referring to fig. 1, the desktop screen capturing method based on window filtering specifically includes:
s110, creating a main process, creating a sub-process based on the main process, and issuing a screen capturing instruction to the sub-process, wherein the screen capturing instruction comprises handle information of a designated window;
s120, collecting desktop images based on the subprocesses, filtering designated windows in the desktop images according to the handle information, generating desktop screen shots and sending the desktop screen shots to the main process, or sending screen shot abnormal information to the main process under the condition of abnormal screen shots;
s130, receiving the desktop screen capturing or the screen capturing abnormal information based on the main process, and re-executing the desktop screen capturing operation under the condition that the screen capturing abnormal information is received.
When the desktop screen capturing operation is carried out, the dual processes are created through the screen capturing application to execute the desktop screen capturing operation containing window filtering. The screen capturing application creates a sub-process by using the main process through creating the main process, and performs desktop screen capturing and window filtering through the sub-process to obtain a screen capturing image meeting the requirement of a user. When the screen capturing operation is carried out by a single process, the resolution ratio switching may cause the process to crash, so that the screen capturing failure is caused. Therefore, the desktop screen capturing operation is executed through the main process and the starter process, and even when the sub-process screen capturing is abnormal, the main process can execute the desktop screen capturing operation again, so that the fault tolerance of the screen capturing operation is ensured. On the other hand, because the multi-process call is easy to cause call failure and cause abnormal screen capturing conditions, the embodiment of the application mainly uses a single process of the subprocess to execute desktop screen capturing and window filtering operations, and the main process is used for receiving the screen capturing result for storage or uploading. Therefore, reliability and stability of desktop screen capturing are guaranteed, and user experience is improved.
The following describes the scheme by taking the desktop screen capturing operation of the computer as an example. Specifically, when the desktop screen capturing is performed, the user performs man-machine interaction with the computer to trigger the desktop screen capturing function. The desktop screenshot function can be used for screenshot of the desktop or recording a video image of a segment of desktop screenshot. And the computer triggers the operation of the screen capturing application by responding to the interactive operation of the user. After the screen capturing application is started, a main process is firstly established, and desktop screen capturing operation is carried out by using the main process and a screwdriver process. The main process generates handle information of a designated window according to the designated window which needs to be filtered by the desktop, and further attaches the handle information to an instruction when a screen capturing instruction is issued to the sub-process, so that the sub-process can clearly determine the window position of the desktop screen capturing which needs to be filtered. As shown in FIG. 2, the main process creates an Inter-process communication link (i.e., IPC, inter-Process Communication) with the sub-process by creating the sub-process, issues a screen capture instruction and receives a screen capture result returned by the sub-process.
Before the method, the appointed window is preset according to the screen capturing content which is actually required to be filtered by the screen capturing application, and the subsequent main process can send handle information according to the preset appointed window when the desktop is captured, and instruct the subprocess to carry out the appointed window filtering operation. Where a Handle is an identifier that identifies an object or item and may be used to describe a form, file, etc. The problem of the memory management mechanism, i.e. the virtual address, is basically caused by setting up a handle for the Windows system. In short, since the address of data needs to be changed, and the change needs to be recorded and managed after the change, the system uses a handle to record the change of the data address. In programming, a handle is a special smart pointer that is used when an application is to reference a memory block or object managed by other systems (e.g., databases, operating systems). Based on the characteristic, when the subprocess carries out window filtering, the position of the window needing to be filtered can be accurately found by utilizing the handle information, and the part of display content is filtered.
Alternatively, the specified window may be a window type corresponding to the under-desktop requirement filtering or a display content corresponding to the desktop location. For example, in order to avoid content leakage for the corresponding window type during a desktop screenshot, it is desirable to avoid that part of the content from being intercepted for transmission. Based on the requirement, the display content of a certain window type displayed on the desktop can be filtered, and the part of the content is prevented from being stored or transmitted in a screen capturing mode. Similarly, for a control which does not need to be displayed in a certain part of the desktop screen capturing, in order to optimize the screen capturing display effect, the content displayed in the fixed position of the part is filtered.
When executing the screen capturing instruction issued by the main process, the subprocess further filters the filter window content at the indicated position of the corresponding handle information in the desktop image according to the handle information by collecting the desktop image, thereby obtaining the desktop image with the designated window content filtered. For example, when recording a screen desktop, control buttons of a system are also displayed on the screen, and pushing or recording requires the control buttons to be displayed. At the moment, the desktop image is acquired through the subprocess, then the position of the control button is found according to the handle information provided by the main process, and the control button on the desktop image is filtered, so that the desktop image in actual demand is obtained. And by analogy, the filtering operation is carried out on all desktop screen shots in the recording process, so that screen shot videos required by users can be obtained.
And for the subprocess, after the desktop image filtering is completed, the generated desktop screen capture is sent to the main process, and the main process stores or transmits the generated desktop screen capture, so that the whole desktop screen capture flow is completed. In addition, if the screen capturing process is abnormal, in order to ensure the screen capturing reliability, the subprocess sends abnormal information to the main process, and the main process re-executes the screen capturing operation of the desktop according to the abnormal information of the screen capturing process. Therefore, the reliability of desktop screen capturing is further guaranteed, the condition that screen capturing fails under abnormal conditions of screen capturing is further avoided, and the screen capturing experience of a user is improved.
Specifically, the main process is created based on a preset screen capturing application, and the screen capturing application is started through a system set display. When installing a screen capture application, it is necessary to assign the screen capture application to be opened only by the set display of the system. It should be noted that, in the case of multiple graphics cards, the independent graphics card is not adapted to the screen capturing application, which may cause a black screen in the screen capturing image. Therefore, by designating the open channel of the screen capturing application, the success rate of the screen capturing operation can be ensured, and unnecessary abnormal conditions can be avoided.
Further, the screen capturing anomaly information includes screen change anomaly information or screen capturing failure anomaly information. When the subprocess determines that the screen capturing is abnormal, screen change abnormal information or screen capturing failure abnormal information is generated according to different abnormal conditions of the screen capturing, and the corresponding screen capturing abnormal information is reported to the main process. And the main process performs screen capture exception processing according to different screen capture exception information so as to further improve the reliability and fault tolerance of desktop screen capture.
When the subprocess executes the screen capturing operation, a task queue of one thread is created in the subprocess, and the desktop image of the magnetic identification screen capturing is processed, as shown in fig. 3. The subprocess collects desktop images through initializing the magnifications, and sets handles of windows to be filtered. And further filtering the appointed window of the desktop image according to the handle information to obtain a corresponding desktop screen shot. After the operation is finished, the subprocess carries out logic judgment of the screen capturing abnormality, and whether the screen capturing abnormality occurs currently or not is confirmed.
Optionally, the subprocess determines screen capturing abnormality under the condition that the resolution of the screen changes before and after the desktop screen capturing operation, and sends the screen changing abnormality information to the main process. It will be appreciated that, due to the variation of the resolution of the screen, or in the case of multiple screens, the resolution of the main screen varies before and after the screen capture, which may result in different screen capture information before and after the screen capture, such as different widths and heights of the screen capture images. This can result in the generated screen shots failing to meet the user's needs. Based on the above, the sub-thread monitors the screen resolution and the main screen resolution before and after screen capturing, judges whether the screen resolution changes before and after screen capturing, and generates abnormal screen change information when the resolution changes (such as a user adjusts screen resolution parameters before and after screen capturing). And then sends this screen change abnormality information to the main process to handle the screen capture abnormality by the main process.
And for a main process, under the condition that the received screen capturing abnormal information is the screen changing abnormal information, clearing the current subprocess based on the main process, and reconstructing the subprocess to execute desktop screen capturing operation. Because of the screen capturing abnormality caused by the screen resolution change, a new subprocess can be recreated for desktop screen capturing operation by clearing the current subprocess. And re-monitor whether the screen resolution changes before and after the screen capture. By the method, screen capturing exception handling under the condition of screen change exception can be completed, and reliability of desktop screen capturing is guaranteed. Optionally, if the desktop screen capturing operation is performed by the repeated setting number reconstruction sub-process, a corresponding prompt can be output to inform the user of frequent change of the current screen resolution, so as to solve the frequent screen capturing abnormality through user intervention.
On the other hand, under the condition that the desktop screen capturing operation continuously fails for a set number of times, the subprocess determines the screen capturing abnormality and sends the abnormal information of the screen capturing failure to the main process. The subprocess judges whether the desktop screen capturing is successful or not by detecting whether the desktop screen capturing is successful or not, and if the situations such as screen capturing and the like occur, the screen capturing is considered to be failed. At this time, the subprocess continuously executes the desktop screen capturing process by referring to the original screen capturing mode. For example, the screen capturing operation is continuously performed 5 times, and whether the screen capturing is successful is detected in this process. If the screen capturing is successful, the current screen capturing operation is determined to be completed. Otherwise, if the screen capturing operation is continuously executed for 5 times and still fails, abnormal information of the screen capturing failure is sent to the main process so as to inform the current condition of the screen capturing failure. It can be understood that, for the situations of sub-thread initialization failure, display card driving failure, system abnormality, failure in interface call and the like, the failure of the screen capturing operation of the sub-thread is possibly caused, at this time, if the sub-thread is initialized, the problem of memory leakage and the like can be possibly caused, based on the fact, the method and the device notify the main thread of the abnormal screen capturing under the condition that the screen capturing operation is repeated for 5 times and still cannot be successfully captured, so that the main thread processes the abnormal screen capturing, and the success rate of the screen capturing operation is ensured.
And for the main process, switching to a default screen capturing mode to execute desktop screen capturing operation under the condition that the received screen capturing abnormal information is the screen capturing failure abnormal information. It can be appreciated that, considering that the normal screen capture cannot be obtained by using the identification capture mode at this time, the embodiment of the application provides a spam capture strategy, and the system default capture mode is switched to execute the desktop capture operation. The desktop screen shots that result at this time will include the content of the specified window.
By detecting different abnormal screen capturing conditions, the abnormal screen capturing is adaptively processed, so that a normal desktop screen capturing can be obtained for an end user, and the screen capturing experience of the user is ensured.
Finally, as shown in fig. 3, when the desktop screen capturing operation is successful, the sub-thread encodes the desktop screen capturing operation and converts the encoded desktop screen capturing operation into a video image in an H264 format. And so on, by executing the desktop screen capturing operation based on window filtering one by one, obtaining the desktop screen capturing of the desktop recorded video. The desktop screenshots are sent to a main process through an inter-process communication link, and the main process receives desktop screenshots for saving or transmitting so as to meet the use requirements under the corresponding scene.
In one embodiment, in order to further improve the desktop screen capturing efficiency, in the process of performing desktop screen capturing, the screen capturing application directly selects a default screen capturing mode to perform desktop screen capturing by detecting whether a designated window exists on the desktop or not and under the condition that the fact that the designated window does not exist on the current desktop is detected. And performing desktop window filtering by using a recognition screen capturing mode only when the fact that the designated window exists on the desktop is detected. The desktop screen capturing is performed by adaptively selecting the corresponding screen capturing mode, so that the screen capturing can be rapidly performed on a scene which does not need window filtering, and the user experience is further improved.
In addition, in one embodiment, for the desktop screen capturing which completes window filtering, the main process can also check the window filtering condition of the desktop screen capturing by calling a detection tool which is set, so as to judge whether the window is normally filtered. The detection tool can adopt an image detection mode, and if the image features of the appointed window exist on the desktop screen capture, the failure of the current desktop screen capture window filtration is indicated, and the desktop screen capture needs to be carried out again; otherwise, the current desktop screen capturing window is successfully filtered. By using the image detection mode, the window filtering result of the desktop screen capturing is accurately verified, and the more reliable and stable desktop screen capturing is realized.
Creating a subprocess based on the main process by creating the main process, and issuing a screen capturing instruction to the subprocess, wherein the screen capturing instruction comprises handle information of a designated window; collecting desktop images based on the subprocesses, filtering designated windows in the desktop images according to the handle information, generating desktop screen shots and sending the desktop screen shots to the main process, or sending screen shot abnormal information to the main process under the condition of abnormal screen shots; and receiving the desktop screen capturing or the screen capturing abnormal information based on the main process, and re-executing the desktop screen capturing operation under the condition that the screen capturing abnormal information is received.
