The hardware or software architecture in some embodiments may be based on the description in the above embodiments, and in some embodiments may be based on other hardware or software architectures that are similar to the above embodiments, and it is sufficient to implement the technical solution of the present application.

In some embodiments, a video call application may be set in the application center, and when a user clicks the video call application icon control, the display device may open the video call application, control the display to display a main interface of the video call application, and the user may select a called terminal to perform video call on the main interface; or when the display device displays the video call invitation, the user serves as a called terminal, can accept the video call invitation initiated by the calling terminal, and carries out video call with the calling terminal.

During a video call, a user may have a need to capture a screen of a display device. When the display device is a mobile terminal, a user can perform screenshot by pressing a preset combination key on the mobile terminal, such as a power key and a volume reduction key, or perform screenshot by clicking a screen, such as finger joint screenshot, or perform screenshot by touching the screen, such as three-finger screenshot; when the display device is a television, the user cannot capture the screen of the display picture in the commonly-used screen capture mode due to the fact that the television is large in size, few in keys, non-touch screen and the like.

In order to solve the technical problem, the screen capture control is arranged on the video call interface, and screen capture is achieved by triggering the screen capture control.

Referring to fig. 6, which is a schematic view of a video call interface according to some embodiments of the present application, as shown in fig. 6, in a process of video call between two users, a display device may control a display to display two call windows, and images collected by cameras of display devices of both parties of the call are respectively displayed in the two call windows. One of the call windows can be a main window and can be fully paved with a display of the display device, namely, the call window is displayed in a full screen mode, and the other call window can be a secondary window and can be displayed in a floating window mode above the main window. A control menu can be arranged in the layer above the main window, and the control menu can comprise a plurality of conversation controls, such as 'closing a microphone', 'closing a camera', 'opening a picture focus', 'magic prop', 'hanging up', 'switching layout', 'small window chatting' and 'screen capturing'. In fig. 6, "screen capture" indicates a screen capture control, and the screen capture control is selected, and the highlighting mode includes setting the ground color of the call control to white. In some embodiments, to avoid the image in the call window being blocked by the control menu and improve the user video call experience, the control menu may be configured to be hidden without receiving a user operation within a preset time, and the preset time may be 3 to 5 seconds. When the control menu is hidden and the user needs to operate the control in the control menu, a preset instruction can be input to the display device to call up the control menu, the preset instruction can be a trigger signal generated by operating a preset key on the control device 100, and when the display is full-screen, the direction key can be a bottom-layer video source response key, so that the preset key can be the direction key, and certainly, the preset key can also be set as other keys, such as a "screen display" key. When the control menu is displayed and the user does not need to operate the control in the control menu, the control menu can be hidden by triggering a preset key and the like, and further, a prompt word such as 'pressing a top key to retract an operation button' can be arranged on the call window to prompt the user to operate the top key in the direction.

Referring to fig. 7, a screen capture interaction diagram of the present application according to some embodiments is shown. As shown in fig. 7, the user may interact with the display device to cause the display device to display the screenshot, or to control the display device to re-screenshot; the display device can interact with the server, and then displays the two-dimensional code on the screenshot.

In some embodiments, the user may trigger the screen capture control by selecting and clicking the screen capture control by operating the control device 100, so as to generate a trigger signal of the screen capture control.

In some embodiments, the trigger signal for the screen capture control may also be other signals, such as a voice capture instruction, which may be an instruction including a voice "screen capture".

After the display equipment receives the trigger signal of the screenshot control, if the control menu is in a display state, the control menu is hidden, then the screenshot is generated, and the screenshot is displayed on the display.

Furthermore, the display device can send the bitmap data of the screenshot to the server, generate a two-dimensional code according to the network address returned by the server and used for storing the bitmap data, display the two-dimensional code on the screenshot, and enable a user to access the server through a two-dimensional code scanning mode and download the screenshot.

In some embodiments, the display device may further display a re-screen-capture control on the screenshot, and after the user clicks the re-screen-capture control or issues a voice screenshot instruction, the display device may push out the screenshot display and re-display a control menu, where the control menu is set as the screenshot control, so that the user can directly click the screenshot control and re-screen the screenshot.

For further explanation on the process of acquiring the screenshot by the user, the embodiment of the present application further provides an interactive decomposition schematic diagram of fig. 7, and referring to fig. 8, the display device may be provided with a UI manager and a screenshot manager, where the UI manager and the screenshot manager are both function modules of a controller of the display device, the UI manager may perform UI drawing, the drawn image may be displayed by a display of the display device, the screenshot manager may interact with the UI manager to provide a screenshot and a two-dimensional code required by UI drawing for the UI manager, and the screenshot manager acquires a network address stored in the screenshot according to the interaction with the server and generates the two-dimensional code according to the network address.

In some embodiments, after the user triggers the screen capture control by clicking the screen capture instruction or sending a voice screen capture instruction, the UI manager may generate a screen capture acquisition request according to a trigger signal of the screen capture control, where the screen capture acquisition request may be used to hide a display control menu on one hand and to start a screen capture acquisition thread on the other hand.

After the screenshot obtaining request is generated, the UI manager can control the UI to hide the control menu, and images which are not shielded by the control menu can be conveniently obtained.

In some embodiments, hiding the control menu may be implemented by revoking the layer, in some embodiments, hiding the menu may also be implemented by setting the layer to be fully transparent, and in other embodiments, hiding the menu may also be implemented by setting the layer to be invisible.

And the UI manager sends a screenshot obtaining request to the screenshot manager, and the screenshot manager generates a screenshot and feeds the screenshot back to the UI manager. The screenshot manager can generate the screenshot by acquiring BitMap (BitMap) data.

In some embodiments, the screenshot manager may obtain bitmap data of all frames displayed by the current system through a reflection method, for example, obtaining bitmap data through a reflection call to the screen of surface control. The reflection calling is a mode of calling a class or an object by using a reflection mechanism, the reflection mechanism belongs to a java language mechanism, in a running state, all attributes and methods of any class can be obtained, any method and attribute (including private methods and attributes) of any object can be called, the function of the dynamically obtained information and the method for dynamically calling the object is called as the reflection mechanism of the java language, and the reflection calling can be carried out without dependence by the known class name and method name. Since the android system is a system developed based on the JAVA language, a reflective call can be made to a display device on which the system is mounted. The surfacontrol is a surface control class of an android frame, when a controller acquires a system authority, that is, when uid = android, the controller may reflect and call a screenshop of the class to acquire data being rendered by a current screen, such as bitmap data, so as to generate a screenshot, and it is also the case that the controller reflects and calls the screenshop of the class to acquire all data being rendered by the current screen, so that a finally acquired screenshot includes a control menu if the control menu in the layer is not hidden, which is unacceptable when a subsequent user switches on or shares or otherwise uses the current screen, and therefore the control menu is hidden in the scheme provided by the present application. The process of hiding the screenshot is as follows:

1. a surfacontrol instance is created in advance. The bitmap object is made available by creating a SurfaceControl instance. The creation process of the SurfaceControl instance may include defining a reflection acquisition surfesesion class, defining a reflection acquisition surfecerol class, and defining a method of reflection acquisition screenhot. When defining the reflection to obtain the surface control class, parameters of a bitmap data acquisition function such as screen capture, an image width such as 1280, an image height such as 720, a pixel format such as RGB _565 and the like can be defined; when a method for acquiring the screenshot by reflection is defined, the method acquired in the SurfaceControl class is defined as the screenshot method.

2. The bitmap object is reflected to the screen shot method in advance. And reflecting the bitmap object to a screenshop method by using a reflection mechanism, and acquiring data, such as bitmap data, which is currently rendered by a screen by using the screenshop method.

3. And responding to a trigger signal of the screen capture control, and calling a screen shot method by acquiring function reflection to acquire bitmap data. The acquisition function is a pre-created function that provides bitmap data to the controller. According to a trigger signal of the screen capture control, the screen capture manager can start an acquisition function to acquire bitmap data, wherein the acquisition function can be configured to judge whether the system authority can be acquired or not, if the system authority can be acquired, a bitmap object is called, and the bitmap object is reflected to a screenshot method to output the bitmap data.

In some embodiments, the capture function cannot obtain the system permission, and at this time, the screenshot manager may obtain bitmap data of all the frames currently displayed by the system through the mediaproject manager. The mediaproject manager is a screen recording service uniformly called by an application layer under an android frame, and can capture a current display frame by calling the service application, and the implementation mode is as follows:

1. acquiring a MediaProjectionManager instance through getSystemService;

2. calling createScreenCaptureIntent of a manager to obtain intent applying screen capture, starting Activity according to the intent, and obtaining returned intent in a callback onActityResult;

3. mediaproject is acquired by the manager instance, thereby obtaining bitmap data.

It can be seen that the reflection method can be preferentially used to obtain bitmap data when the video call application has the system right, and the bitmap data can be obtained by mediaproject manager when the video call application does not have the system right.

In some embodiments, after obtaining the bitmap data, the screenshot manager may generate a screenshot according to the bitmap data, and send the screenshot to the UI manager.

In some embodiments, the screenshot manager, after generating the screenshot, can also store the screenshot in a location accessible to the UI manager for the UI manager to recall.

And after acquiring the screenshot, the UI manager generates a screenshot popup window, loads the screenshot into the screenshot popup window, and controls the UI to popup the screenshot popup window, so that the screenshot is displayed, and a user can see the screenshot on the display equipment.

In some embodiments, to facilitate the user to save the screenshot, the controller may save bitmap data in a preset path of the display device, generate a local file, and then upload the local file to the server via a stream (data stream), for example, upload the local file via an Http post request whose contentType is application/octet-stream.

In some embodiments, the screenshot manager can perform parallel processing, on one hand, a screenshot is generated according to bitmap data and sent to the UI manager, on the other hand, the bitmap data is stored as a local file, the local file is uploaded to the server, and the screenshot generation efficiency is improved.

After receiving the screenshot file, the server allocates a picture identifier for the screenshot file, feeds the picture identifier back to the display device, processes the screenshot file, and generates an H5 page loaded with the screenshot corresponding to the bitmap data, where the picture identifier may include MediaID, and the MediaID may be a random character string. After receiving the MediaID, the screenshot manager of the display device can generate a picture access request containing the MediaID, send the picture access request to the server, and after receiving the picture access request, the server extracts the MediaID in the picture access request, searches for an H5 page corresponding to the MediaID, and further feeds back a network address of the H5 page to the display device. The screenshot manager of the display device can generate the two-dimensional code according to the network address of the H5 page and send the two-dimensional code to the UI manager, or the screenshot manager can store the two-dimensional code to a storage position accessible by the UI manager so that the UI manager can call the two-dimensional code.

And after the UI manager acquires the two-dimensional code, the two-dimensional code is superposed above the screenshot in the screenshot popup window. The two-dimensional code is configured to jump to the H5 page in response to a scan signal.

A user can scan the two-dimensional code through the mobile terminal to access the H5 page, a storage option can be popped up by pressing the screenshot for a long time on the H5 page, and the screenshot can be stored to the mobile terminal by triggering the storage option by the user.

In some embodiments, the UI manager may also expose a re-screen control. Referring to fig. 9, which is a schematic diagram of a screenshot interface according to some embodiments, as shown in fig. 9, a screenshot displayed on the screenshot interface may include two conversation windows, a re-screenshot control and a two-dimensional code. Wherein, below the two-dimensional code, but the suggestion is shown: and scanning the code to obtain a picture, and prompting a user to scan the code. In some embodiments, when the user is not satisfied with the screenshot image, the screenshot re-control can be triggered by clicking the screenshot re-control or sending a voice screenshot command, and a trigger signal of the screenshot re-control is generated.

And the UI manager controls the UI to exit the screenshot popup window according to the control signal for indicating the screenshot again, and displays the control menu shown in the figure 6, so that the user can trigger the screenshot control again to perform screenshot.

Further, when the control menu is displayed, the UI manager may default to select the screenshot control in the control menu, and the selection may include setting the focus of the display interface on the screenshot control in the control menu, that is, highlighting the screenshot control, so that the user may conveniently trigger the screenshot control through the control device 100, for example, clicking a "confirm" button on the control device 100 to trigger the screenshot control.

To further explain the screenshot process, an embodiment of the present application provides a screenshot method in a video call, referring to fig. 10, where the screenshot method includes the following steps:

step S110: and responding to a trigger signal of a screen capture control received in a video call interface, controlling the display to hide a control menu, and acquiring bitmap data.

In some embodiments, the trigger signal of the screen capture control may be a signal that the screen capture control is selected and clicked or a voice screen capture instruction. Within a preset time after the video call application is started, or after the user calls the control menu, the user may trigger the screenshot control in the control menu, for example, select the screenshot control by operating the control device 100, and then trigger the screenshot control by the control device 100, for example, click an "ok" button on the control device 100 to trigger the screenshot control, or send a voice screenshot instruction to the display device to trigger the screenshot control.

After the user triggers the screen capture control, the controller of the display device can hide a control menu in the video call interface and acquire bitmap data of the current display interface.

In some embodiments, the controller may obtain bitmap data of all frames displayed by the current system through a reflection method; in some embodiments, the controller may also obtain bitmap data for all frames currently being presented by the system via mediaproject manager.

In some embodiments, the controller may pop up a screenshot pop-up on the current system presentation screen, displaying the screenshot within the screenshot pop-up, which may be smaller than a full screen window of the display.

Step S130: and sending the bitmap data to a server, and acquiring a picture identifier which is returned by the server and corresponds to the bitmap data.

In some embodiments, the controller may store the bitmap data in a preset path of the display device, generate a screenshot file, and then transmit the screenshot file to the server.

After receiving the screenshot file, the server allocates a MediaID for the screenshot file, feeds the MediaID back to the display device, processes the screenshot file, and generates an H5 page loaded with the corresponding screenshot of the bitmap data.

Step S140: and acquiring a network address of the server for storing the bitmap data according to the picture identification.

In some embodiments, the controller of the display device may generate a picture access request including the MediaID after receiving the MediaID, send the picture access request to the server, and after receiving the picture access request, the server extracts the MediaID in the picture access request, searches for the H5 page corresponding to the MediaID, and feeds back the network address of the H5 page to the display device.

Step S150: and generating a two-dimensional code according to the network address, and controlling the display to display the two-dimensional code in the screenshot popup window.

In some embodiments, the controller of the display device may generate a two-dimensional code based on the network address of the H5 page, the two-dimensional code configured to jump to the H5 page. The controller refreshes the two-dimensional code into a screenshot popup window of the display, so that a user can scan the two-dimensional code through the mobile terminal to access the H5 page, and the picture is stored in the H5 page and then is sent to the mobile terminal.

Furthermore, a screen re-capturing control can be displayed in the screen capturing popup window, when a user is not satisfied with the screen capturing image, the screen re-capturing control can be triggered, a control signal for indicating the re-capturing is generated, the controller controls the display to exit the screen capturing popup window according to the control signal for indicating the re-capturing, and the control menu shown in fig. 6 is displayed, so that the user can trigger the screen capturing control again to capture the screen.

Further, the controller may set the focus of the display interface on a screen capture control in the control menu, that is, highlight the screen capture control, so that the user may trigger the screen capture control through the control device 100, for example, click a "confirm" button on the control device 100 to trigger the screen capture control.

As can be seen from the above embodiments, in the embodiments of the present application, a screenshot control is set on a video call interface, and when a user triggers the screenshot control, a control menu is hidden to capture a screenshot, so that the screenshot is obtained and displayed on a display of a display device, so that the user can view the screenshot; further, bitmap data acquired in the screen capturing process is stored in a screen capturing file, the screen capturing file is uploaded to a server, the server generates an H5 page and a MediaID according to the screen capturing file, a display device can acquire a network address of the H5 page according to the MediaID, a two-dimensional code is generated according to the network address, the two-dimensional code is displayed on the screen capturing, a user can acquire the screen capturing on the H5 page on the mobile terminal in a mode of scanning the two-dimensional code, the screen capturing can be stored on the mobile device, and the user can store and edit the screen capturing conveniently.
