Fig. 4 is a flowchart illustrating a screen content sharing method in an embodiment, which is described by taking a process of the first user terminal 101 performing screen content sharing as an example.

As shown in fig. 4, the screen content sharing method in this embodiment includes:

step S401: when a screen content sharing instruction is received through a video session interface, sending a screen content sharing request to a background server, wherein the screen content sharing request comprises a first user identifier;

step S402: when a sharing confirmation message returned by the background server is received, switching to a content sharing interface, and setting a screen sharing video source of the content sharing interface;

step S403: sending a screen sharing notification message to the background server, and sending the screen sharing notification message to each second user terminal corresponding to each second user identifier by the background server, wherein the first user identifier is associated with each second user identifier and a video session room identifier corresponding to the video session interface;

step S404: and acquiring the screen content data to be shared of the screen sharing video source, displaying the screen content data to be shared in a sharing content display sub-window of the content sharing interface, and sending the screen content data to be shared to each second user terminal.

According to the scheme of the embodiment, the terminal can receive the screen content sharing instruction through the video session interface and send the screen content sharing request to the background server, the terminal can switch to the content sharing interface after receiving the sharing confirmation message of the background server, set the screen sharing video source and notify other second user terminals for screen sharing through the background server, so that the content sharing between the current user terminal and other second user terminals in the video session process is realized, namely when the screen content sharing is required, the sharing of the screen content can be initiated directly based on the video session process, and based on the user terminals associated with the video session room identifier for video session, the sharing parties for screen content sharing can be determined without using a specific screen content sharing system, and special registration, connection and other processing are not required for sharing the screen content, so that the interactive performance and interactive performance of the shared content during information sharing are improved, and the convenience and quickness of screen content sharing are improved.

When the screen content sharing instruction is received through the video session interface, the screen content sharing instruction may be received in any possible manner, for example, a sharing button may be disposed on the video session interface, and the screen content sharing instruction is received through the sharing button on the video session interface.

The screen content sharing method of the embodiment can share any content displayed on the terminal screen, so that in practical technical application, a terminal user can select what content is to be shared. The specific selection may be performed in any possible manner, as long as the shared screen content can be determined before the screen content data to be shared is displayed and sent to the second user terminal in step S104.

In one example, the selection may be made before sending the screen content sharing request to the backend server upon receiving the screen content sharing instruction. At this time, after the screen content sharing instruction is received through the video session interface and before the screen content sharing request is sent to the background server, a selection instruction may be received, where the selection instruction includes a to-be-shared content identifier, and the to-be-shared content identifier is a window identifier or a desktop screen identifier. At this time, when the screen sharing video source of the content sharing interface is set, the acquired video data corresponding to the identifier of the content to be shared may be set as the screen sharing video source.

In another example, the sharing confirmation message returned by the background server may be received. At this time, when the screen sharing video source of the content sharing interface is set, the following method may be adopted:

receiving a selection instruction, wherein the selection instruction comprises a content identifier to be shared, and the content identifier to be shared is a window identifier or a desktop screen identifier;

and setting the collected video data corresponding to the content identification to be shared as the screen sharing video source.

In a specific example, process window information of all processes can be obtained by scanning all processes of the user terminal where the user terminal is located currently; acquiring a desktop screenshot; displaying the obtained process window information and the desktop screenshot; and receiving the window sharing selection instruction from a display interface which displays the progress window information and the desktop screenshot.

Further, when the content identifier to be shared is a window identifier, a first position coordinate of a cursor on a screen can be further captured; and converting the first position coordinate to obtain a second position coordinate of the cursor relative to a window area corresponding to the window identification. At this time, the screen content data to be shared further includes the second position coordinate. Therefore, the cursor of the user terminal can be shared to other user terminals while the screen content is shared.

Further, in an example, a screen sharing end request may also be sent to the background server when a screen sharing stop instruction is received. And when receiving an end confirmation message returned by the background server according to the screen sharing end request, switching to a video session interface, stopping collecting data of the video sharing video source, sending a sharing stop message to the background server, and sending the sharing stop message to each second user terminal by the background server.

In another example, the sharing confirmation message, the screen sharing notification message, may include address information of the video data server. At this time, when the screen content data to be shared is sent to each second user terminal, the screen content data to be shared may be sent to a video data server and then sent to each second user terminal through the video data server. On the other hand, after the screen content data to be shared is sent to the video data server, each second user terminal downloads the screen content data to be shared from the video data server every predetermined time period according to the address information of the video data server.

Correspondingly, a flow chart of a screen content sharing method in another embodiment is shown in fig. 5. In this embodiment, a process of the background server 103 is described as an example.

As shown in fig. 5, the screen content sharing method in this embodiment includes:

step S501: receiving a screen content sharing request sent by a first user terminal, wherein the screen content sharing request comprises a first user identifier of the first user terminal;

step S502: acquiring a video session room identifier associated with the first user identifier, and returning a sharing confirmation message to the first user terminal;

step S503: receiving a screen sharing notification message sent by the first user terminal after the first user terminal switches the video session interface to the content sharing interface according to the sharing confirmation message and sets a screen sharing video source of the content sharing interface;

step S504: and sending the screen sharing notification message to second user terminals which are associated with the video session room identification and correspond to second user identifications except the first user identification.

In an example, after obtaining the video session room identifier associated with the first user identifier, the background server may set the state of the video session room corresponding to the video session room identifier as a locked state, and then return a sharing confirmation message to the first user terminal. Thereby avoiding the problem of conflict generated by other user terminals also initiating screen content sharing requests.

In another example, the sharing confirmation message and the screen sharing notification message may include address information of the video data server. Therefore, in the subsequent screen content sharing process, the first user terminal can send the screen content data to be shared to each second user terminal through the video data server.

In another example, a screen sharing end request sent by the first user terminal may also be received, wherein the screen sharing end request includes the first user identifier; and returning an end confirmation message to the first user terminal; and receiving a sharing stopping message returned by the first user terminal according to the end confirmation message, and sending the sharing stopping message to each second user terminal. When the state of the video session room corresponding to the video session room identifier has been set to the locked state, after receiving the sharing stop message sent by the first user terminal, the state of the video session room corresponding to the video session room identifier may also be set to the unlocked state.

Fig. 6 is a flowchart illustrating a screen content sharing method in another embodiment, which is described by taking a processing procedure of a shared terminal (e.g., the second user terminal shown in fig. 1) as an example.

As shown in fig. 6, the screen content sharing method in this embodiment includes:

step S601: receiving a screen sharing notification message sent by a background server, wherein the screen sharing notification message comprises a first user identifier;

step S602: switching from a video session interface to a content sharing interface according to the screen sharing notification message;

step S603: and receiving screen content data to be shared sent by a first user terminal corresponding to the first user identifier, and displaying the screen content data to be shared on a shared content display sub-window of the content sharing interface.

In a specific example, the screen content data to be shared may further include: and the cursor is corresponding to the second position coordinate of the window area in the screen content data to be shared. At this time, when the screen content data to be shared is displayed in the shared content display sub-window of the content sharing interface, the cursor may be displayed at the second position coordinate in the shared content display sub-window at the same time.

In another embodiment, the screen sharing notification message may further include address information of the video data server. Accordingly, in one particular example, the second user terminal may receive the screen content data to be shared from the video data server. In another specific example, the second user terminal may download the screen content data to be shared from the video data server every predetermined time period according to the address information of the video data server.

Based on the embodiments described above, fig. 7 shows an interaction flow diagram in screen content sharing in a specific application example. This example illustrates an interaction flow between devices that perform screen content sharing simultaneously during a specific video session.

In the illustration of fig. 7, it is assumed that the video session request is initiated by the first user terminal. It should be understood that the video session request may also be initiated by another user terminal, and in the embodiment of the present invention, the terminal initiating the video session request and the terminal initiating the screen content sharing request need not be limited to the same user terminal.

With reference to fig. 7, in an actual technical application, when a video call instruction sent by a terminal user by clicking a relevant button such as "video session", "video chat", or the like needs to be received, a first user terminal sends a video call request to a background server, where the video call request carries a first user identifier of the first user terminal. Meanwhile, the video call request may also carry a second user identifier of each second user terminal to be video-called, or a group identifier of a group or discussion group in which the first user identifier is located.

And after receiving the video call request, the background server sends the video call request to a second user terminal corresponding to a second user identifier when the video call request carries the second user identifier. And when the video call request carries the group identifier, acquiring other second user identifiers except the first user identifier in the user identifiers associated with the group identifier, and sending the video call request to second user terminals corresponding to the second user identifiers. It is understood that only one second user terminal is shown in fig. 7 for simplicity of illustration, in practical technical applications, the number of the second user terminals may also include a plurality of second user terminals, and the processing procedure of the plurality of second user terminals may be the same as the processing procedure of the second user terminal described in fig. 7.

And after receiving the video call request sent by the background server, the second user terminal determines whether the video call is needed or not based on the selection of the terminal user. And if the video call is needed, returning video call confirmation information to the background server.

And after receiving the video call confirmation information returned by the second user terminal, the background server creates a video session room for the video call to obtain a video session room identifier. It can be understood that when the group identifier is carried in the video call request, a video session room can be created as long as one second user terminal returns video call confirmation information, and it is not necessary to wait for all second user terminals to return video call confirmation information. In addition, when the video call request carries the group identifier, the group identifier may be directly used as the video session room identifier, or the video session room identifier may be created again. And if the video call request carries the second user identifier, a video session room identifier needs to be allocated to the video session associated with the first user identifier and the second user identifier.

The distributed video session room identifier may be returned to the first user terminal and each of the second user terminals, and the first user terminal and each of the second user terminals perform a video session based on the common video session room identifier. And video image data obtained by the first user terminal through shooting by the camera is directly transmitted to each second user terminal through the background server or the third-party data server. On the other hand, video image data obtained by shooting through a camera by any one second user terminal associated with the video session room identifier is directly transmitted to the first user terminal and other second user terminals through the background server or the third-party data server. The video session interface in one example of an application is shown in fig. 11.

In the process of video conversation, the process of screen content sharing can be initiated, so that rich desktop sharing is performed. Taking the example of initiating the sharing by the first user terminal, the user of the first user terminal may send a screen content sharing instruction by clicking a button initiating the screen content sharing, such as "share", and the like on the video session interface, and it can be understood that the button initiating the screen content sharing may also be displayed by a related symbol mark, for example, the first button on the left side of the bottom shown in fig. 11. Therefore, the terminal user can initiate the sharing of the screen content based on the video session process, and special use of a special screen content sharing system and special registration, connection and other processes for sharing the screen content are not needed.

With reference to the schematic processing frame of the terminal when performing screen sharing shown in fig. 8 and the schematic flow diagram of the terminal when initiating screen sharing shown in fig. 9, in the present embodiment, after receiving the screen content sharing instruction through the WEWTalkShareManager of session sharing management, the terminal user can select what content is to be shared through the ScreenWndInfoGrabManager of the related module of sharing content management. For example, the ScreenWndInfoGrabManager may scan all processes of the system of the current ue and obtain information of all processes, including process window information. And acquiring a desktop screenshot, which may be a windows desktop screenshot by taking a windows system as an example. And then displaying the obtained process window information and the desktop screenshot, and displaying the process window information and the desktop screenshot to a terminal user for selection. When displaying, the information of each process window and the screenshot of the desktop may be displayed in a thumbnail mode for the terminal user to select, or may be selected by the terminal user in other modes such as a list and the like. The terminal user can select the content to be shared by clicking the thumbnail, the options in the list or other modes, and sends a window sharing selection instruction, wherein the window sharing selection instruction comprises the content identification to be shared, and the content identification to be shared can be marked as the windowInfo. The identifier of the content to be shared may be a window identifier or a desktop screen identifier, where the window identifier refers to an identifier of a window corresponding to a certain process in this example. Therefore, when screen content is shared, the shared screen content can be not the whole screen of the desktop of the first user terminal, but is related to the current running process of the first user terminal and is a window corresponding to a specific process, so that files to be shared do not need to be uploaded specially for the sharing of the screen content, the sharing of the screen content is simpler, the sharing of any screen content can be realized, and the diversity of the shared screen content is realized.

After a window sharing selection instruction is received and it is determined that a certain window or the whole computer screen needs to be shared, in order to avoid that a plurality of users initiate sharing at the same time, a first user terminal sends a screen content sharing request to a background server. The screen content sharing request includes a first user identifier of the first user terminal.

After receiving the screen content sharing request, the background server returns a sharing confirmation message which can be shared to the first user terminal if no other terminal identifier associated with the video session room identifier is currently shared and the call is normal. Before or while sending the sharing confirmation message, setting the state of the video session room corresponding to the current video session room identifier as a locking state, namely locking the video session room to meet the requirement that the screen content of only one terminal is shared at the same time.

On the other hand, when determining that the first user terminal can share, the background server may further determine address information of a video data server for sharing the screen content by the first user terminal, where the address information of the video data server may be associated with the video session room identifier and may be carried in a sharing confirmation message and returned to the first user terminal.

After receiving the sharing confirmation message sent by the background server, the first user terminal switches the display interface from the video session interface to the content sharing interface, where the content sharing interface in one example is shown in fig. 12.

Meanwhile, a screen sharing video source of the content sharing interface is set, the screen sharing video source is switched to video data of a sharing window or a sharing desktop, for example, a to-be-shared content identifier windowInfo obtained through a window sharing selection instruction can be sent to a screen data capturing engine ScreenCaptureEngine and a window data engine WindowCaptureEngine to determine whether screen sharing or window sharing is performed, and then the selected desktop screen or window data can be captured and collected through the screen data capturing engine ScreenCaptureEngine or the window data engine WindowCaptureEngine.

In an embodiment, after the content sharing interface is switched to, the display of each video window of the video session interface may be directly closed or cancelled, and the camera of the control terminal no longer captures the camera data. In other embodiments, when screen content sharing is performed through the content sharing interface, data of each camera can be displayed simultaneously, and simultaneous interactive sharing of the screen content and the content captured by the cameras is achieved. In this case, in a specific application example, after switching to the content sharing interface, each video window of the video session interface may be reduced and displayed at a specified position of the content sharing interface, where the specified position may be set according to actual application needs, for example, the specified position is displayed in a row at a boundary of the content sharing interface shown in fig. 12. In another specific application example, each video window of the video session interface can be reduced and then displayed in a floating manner at a specified position of the content sharing interface, so that the display position of each video window can be freely adjusted by an end user based on the display requirement. In another specific application example, each video window of the video session interface can be further reduced and then hidden at the edge of the desktop of the current user terminal. In other specific application examples, each video window of the video session interface may be reduced and displayed in other manners. Therefore, the screen content sharing is realized, the video conversation can be carried out, and the interaction performance and the diversity of information sharing are improved.

On the other hand, the first user terminal sends a screen sharing notification message to the background server to inform the background server that the first user terminal is ready for sharing, so as to inform other members of entering a sharing state. The screen sharing notification message carries the first user identifier. In some embodiments, the screen sharing notification message may further carry address information of the video data server.

After receiving the screen sharing notification message, if the screen sharing notification message carries address information of the video data server, the background server may directly send the screen sharing notification message to each second user terminal associated with each second user identifier after finding the video session room identifier associated with the first user identifier and each second user identifier associated with the video session room identifier and other than the first user identifier. On the other hand, if the screen sharing notification message does not carry the address information of the video data server, after the video session room identifier associated with the first user identifier is found, the address information of the video data server associated with the video session room identifier and the second user identifiers except the first user identifier are found, the address information of the video data server is added to the screen sharing notification message and then is sent to the second user terminals associated with the second user identifiers, so as to notify other members in the video session to enter the sharing state.

After receiving the screen sharing notification message, each second user terminal may display the screen sharing notification message, and a terminal user of each second user terminal may determine whether sharing is required based on the displayed screen sharing notification message. And if the terminal user confirms to enter the sharing or does not send an instruction of not entering the sharing, the terminal user enters the sharing state, and if the current video session is not closed normally, the terminal user enters the shared state, switches the video session interface to the content sharing interface and prepares to receive the screen content data to be shared sent by the sharer. The content sharing interface of the shared second user terminal and the content sharing interface of the sharing first user terminal may be the same or have different designs.

After the first user terminal sends the screen sharing notification message to the background server, the first user terminal may capture and collect the selected desktop screen or window data through a screen data capture engine ScreenCaptureEngine or a window data engine WindowCaptureEngine, respectively. Taking sharing of the whole desktop screen as an example, the content of the desktop screen can be captured through the ScreenCaptureEngine, captured data is obtained and sent to the video processing engine wewtalkmanager for processing, and meanwhile, the upper-layer interactive interface can be notified to be refreshed, so that the shared content display sub-window of the content sharing interface of the first user terminal is displayed. Taking sharing of the content of the window as an example, the data of the window to be shared can be captured through the window data engine WindowCaptureEngine, the captured data is obtained and sent to the video processing engine wewtalkmaker for processing, and meanwhile, the upper layer interactive interface can be notified to be refreshed, so that the shared content display sub-window of the content sharing interface of the first user terminal is displayed. In addition, the captured data, namely the screen content to be shared, can be transmitted to each second user terminal through the data platform server, so that data transmission of the screen content to be shared is realized.

In this regard, it is considered that some application systems (such as the Mac system) only provide a screen data collection interface for the whole desktop (or a mobile phone linked to a computer) and there is no direct system interface for the window of the related program to collect data. Therefore, the screen data acquisition interface in the system can be directly called for data acquisition aiming at the sharing of the desktop screen. And for the sharing of the window content, the data acquisition of the window content can be carried out through different mechanisms. For example, after capturing the whole desktop screen data, coordinate conversion is performed on the data to obtain window data of a corresponding window. In a specific example of the present invention, when the content identifier to be shared is a window identifier, a screenshot may be obtained by capturing a window area corresponding to the window identifier according to a predetermined frequency, so as to obtain the screen content data to be shared. Because the frame rate that human eyes can distinguish is basically about 24 frames, the frequency of 24 frames per second can be adopted for window screenshot collection.

Because the format and the size of the screenshot are not beneficial to network transmission, the screenshot of the window obtained by screenshot can be converted into the content data of the screen to be shared in the video frame format which is beneficial to network transmission after the data format and the data quality are converted, and then the content data is sent to the network. The conversion of the specific data format and data quality can be performed in any possible manner as long as the conversion is convenient for the transmission of the network video frame. Taking the MAC platform adopted by the first user terminal as an example, the CGImageRef obtained by sampling may be converted into a uniform CVPixBuffer, and then normal video encoding is performed, followed by network transmission, and the network transmission is sent to each second user terminal through the video data server.

On the other hand, when the content identifier to be shared is a window identifier, a cursor movement event in the whole process can be further monitored, and a first position coordinate of a cursor on a screen is captured; and converting the first position coordinate relative to a window corresponding to the window identifier, projecting the position of the cursor onto the window to be shared, and obtaining a second position coordinate of the cursor relative to a window area corresponding to the window identifier. And carrying the second position coordinate on the screen content data to be shared. Therefore, when the second user terminals acquire the video data source needing to be shared, the second user terminals can also acquire the second position information of the cursor, draw and display the cursor on the video source of the screenshot, and can dynamically see the movement of the cursor on the screen sharing content, so that other shared audiences can also simultaneously view the currently positioned position of the sharer when watching the screen content needing to be shared.

After the first user terminal sends the screen content data to be shared to the video data server, the video data server can actively send the screen content data to be shared to each second user terminal, and the second user terminal can also download the screen content data to be shared from the video data server at intervals of a preset time period according to the address information of the video data server.

In one embodiment of the invention, only the initiator may end the sharing process. As shown in fig. 10, when the sharing needs to be ended, the user of the first user terminal may send a screen sharing stop instruction by clicking a similar button such as "end sharing" on the content sharing interface, and after receiving the screen sharing stop instruction, the present embodiment sends a screen sharing end request to the backend server, and if the backend server determines that the sharing can be ended, returns an end confirmation message to the first user terminal. And after receiving the ending confirmation message, the first user terminal switches back to a video session interface, stops acquiring data of a window or a desktop by sending an acquisition stopping instruction and the like to a video acquisition engine for acquiring the screen sharing video source, and controls the camera to start to acquire video data normally under the condition that the camera stops acquiring the video data during content sharing, and then recovers to the video session process. In addition, the first user terminal also sends a sharing stopping message to the background server, and the sharing stopping message carries the first user identifier. After receiving the sharing stop message, the background server searches the video session room identifier associated with the first user identifier and each second user identifier associated with the video session room identifier and except the first user identifier, and sends the sharing stop message to each second user terminal corresponding to each second user identifier to notify other members. And after receiving the sharing stopping message, the second user terminal switches back to the video session interface and enters the video session process. Therefore, after the screen content sharing process is finished, the video session interface can be switched back, so that the video session and the screen content sharing can be switched at will, and the method is convenient and fast.

Based on the same idea as the method of each of the above-described embodiments, fig. 13 shows a schematic configuration diagram of a screen content sharing apparatus in an embodiment, which is provided on the first user terminal 101 shown in fig. 1.

As shown in fig. 13, the screen content sharing apparatus in this embodiment includes:

the sharing request module 131 is configured to send a screen content sharing request to a backend server when receiving a screen content sharing instruction through a video session interface, where the screen content sharing request includes a first user identifier;

the first interface switching module 132 is configured to switch to a content sharing interface when receiving a sharing confirmation message returned by the background server, and set a screen sharing video source of the content sharing interface;

a first sharing notification module 133, configured to send a screen sharing notification message to the backend server, where the backend server sends the screen sharing notification message to each second user terminal corresponding to each second user identifier, and the first user identifier is associated with each second user identifier and a video session room identifier corresponding to the video session interface;

the content sharing module 134 is configured to acquire to-be-shared screen content data of the screen sharing video source, display the to-be-shared screen content data in a sharing content display sub-window of the content sharing interface, and send the to-be-shared screen content data to each second user terminal.

When receiving the screen content sharing instruction through the video session interface, the sharing request module 131 may adopt any possible manner, for example, a sharing button may be disposed on the video session interface, and the sharing request module 131 may receive the screen content sharing instruction through the sharing button on the video session interface.

The screen content sharing device of the embodiment can share any content displayed on the terminal screen, so in practical technical application, a terminal user can select what content is to be shared. The specific selection may be performed in any possible manner, as long as the content sharing module 134 can determine the shared screen content before displaying and sending the screen content data to be shared to the second user terminal.

Accordingly, as shown in fig. 13, the screen content sharing apparatus of the present embodiment may further include a shared content selecting module 135.

The sharing content selecting module 135 is configured to receive a selection instruction, where the selection instruction includes a to-be-shared content identifier, and the to-be-shared content identifier is a window identifier or a desktop screen identifier.

At this time, the first interface switching module 132 sets the collected video data corresponding to the identifier of the content to be shared as the screen sharing video source.

In an embodiment, after the first interface switching module 132 switches to the content sharing interface, the display of each video window of the video session interface may be directly closed or cancelled, and the camera of the control terminal no longer captures the camera data. In other embodiments, when screen content sharing is performed through the content sharing interface, data of each camera can be displayed simultaneously, and simultaneous interactive sharing of the screen content and the content captured by the cameras is achieved. In this case, in a specific application example, after switching to the content sharing interface, the first interface switching module 132 may reduce each video window of the video session interface and display the reduced video window at a specified position of the content sharing interface, where the specified position may be set according to actual application needs, for example, the specified position is arranged and displayed at a boundary of the content sharing interface shown in fig. 12. In another specific application example, the first interface switching module 132 may reduce each video window of the video session interface and then float and display the reduced video window at a designated position of the content sharing interface, so that the end user can freely adjust the display position of each video window based on the display requirement. In another specific application example, the first interface switching module 132 may hide each video window of the video session interface from the edge of the desktop of the current user terminal. In other specific application examples, the first interface switching module 132 may also narrow down each video window of the video session interface and display the video window in other manners.

In a specific example, the shared content selection module 135 may scan all processes of the current ue, and obtain process window information of all processes; acquiring a desktop screenshot; displaying the obtained process window information and the desktop screenshot; and receiving the window sharing selection instruction from a display interface which displays the progress window information and the desktop screenshot.

In this case, further, when the content identifier to be shared is a window identifier, the content sharing module 134 captures a window area corresponding to the window identifier according to a predetermined frequency to obtain a window screenshot, so as to obtain the content data of the screen to be shared.

Further, the content sharing module 134 may further capture a first position coordinate of a cursor on the screen when the content identifier to be shared is a window identifier; converting the first position coordinate to obtain a second position coordinate of the cursor relative to a window area corresponding to the window identification; the screen content data to be shared comprises the second position coordinate. Therefore, the cursor of the user terminal can be shared to other user terminals while the screen content is shared.

Further, in a specific example, the sharing confirmation message and the screen sharing notification message may further include address information of the video data server.

In this case, after the content sharing module 134 sends the screen content data to be shared to the video data server, the screen content data may be sent to each second user terminal through the video data server. On the other hand, after the content sharing module 134 sends the screen content data to be shared to the video data server, each second user terminal downloads the screen content data to be shared from the video data server at intervals of a predetermined time period according to the address information of the video data server.

On the other hand, the content sharing module 134 may further convert the data format and the data quality of the screen content data to be shared, and send the converted screen content data to the video data server, and send the converted screen content data to each second user terminal through the video data server. To meet the format and quality requirements of network video transmission.

In one embodiment, as shown in fig. 13, the screen content sharing apparatus in this embodiment may further include:

the sharing ending processing module 136 is configured to send a screen sharing ending request to the background server when receiving a screen sharing stopping instruction; and when receiving an end confirmation message returned by the background server according to the screen sharing end request, switching to a video session interface, stopping collecting data of the video sharing video source, sending a sharing stop message to the background server, and sending the sharing stop message to each second user terminal by the background server.

Further, in a specific technical application, the sharing ending processing module 136 may stop acquiring data of the video sharing video source by sending an acquisition stopping instruction to the video acquisition engine that acquires the screen sharing video source.

Fig. 14 shows a schematic configuration diagram of a screen content sharing apparatus in another embodiment, which is provided on the first user terminal 102 shown in fig. 1.

As shown in fig. 14, the screen content sharing apparatus in this embodiment includes:

the second interface switching module 141 is configured to receive a screen sharing notification message sent by the backend server, where the screen sharing notification message includes a first user identifier; switching from a video session interface to a content sharing interface according to the screen sharing notification message;

and the sharing terminal display module 142 is configured to receive the to-be-shared screen content data sent by the first user terminal corresponding to the first user identifier, and display the to-be-shared screen content data in a sharing content display sub-window of the content sharing interface.

In a specific example, the screen content data to be shared may further include: and the cursor is corresponding to the second position coordinate of the window area in the screen content data to be shared. At this time, when the shared terminal display module 142 displays the screen content data to be shared in the shared content display sub-window of the content sharing interface, the shared terminal display module may simultaneously display a cursor at the second position coordinate in the shared content display sub-window.

In another embodiment, the screen sharing notification message may further include address information of the video data server. Accordingly, in a specific example, the sharing terminal display module 142 may directly receive the to-be-shared screen content data sent by the video data server. In another specific example, the sharing terminal display module 142 may download the to-be-shared screen content data from the video data server at intervals of a predetermined time period according to the address information of the video data server.

In an embodiment, after the second interface switching module 141 switches to the content sharing interface, the display of each video window of the video session interface may be directly closed or cancelled, and the camera of the control terminal no longer captures the camera data. In other embodiments, when screen content sharing is performed through the content sharing interface, data of each camera can be displayed simultaneously, and simultaneous interactive sharing of the screen content and the content captured by the cameras is achieved. In this case, in a specific application example, after switching to the content sharing interface, the second interface switching module 141 may reduce each video window of the video session interface and display the reduced video window at a specified position of the content sharing interface, where the specified position may be set according to actual application needs, for example, the specified position is displayed in a row at a boundary of the content sharing interface shown in fig. 12. In another specific application example, the second interface switching module 141 may reduce each video window of the video session interface and then float and display the reduced video window at a designated position of the content sharing interface, so that the end user can freely adjust the display position of each video window based on the display requirement. In another specific application example, the second interface switching module 141 may hide each video window of the video session interface from the edge of the desktop of the current user terminal after zooming out. In other specific application examples, the second interface switching module 141 may further reduce each video window of the video session interface and display the video window in other manners.

It can be understood that the screen content sharing device shown in fig. 13 and shown in fig. 14 may exist as a common screen content sharing device, that is, the screen content sharing device in an embodiment may include both the screen content sharing device in the example of fig. 13 and the screen content sharing device in the example of fig. 14, so that the screen content sharing device may serve as a sharing end and also serve as a shared end in practical technical applications. Here, when the screen content sharing device includes both the screen content sharing device in the example of fig. 13 and the screen content sharing device in the example of fig. 14, the first interface switching module 132 and the second interface switching module 141 may be integrated into one module.
