As shown in Figure 4, Figure 4 is a schematic diagram of a video screen corresponding to a custom video window displaying 180p; in the figure, 12 custom video windows are preset, and each custom video window corresponds to a 180p video screen, as shown in the figure 5, Figure 5 is a schematic diagram of a custom video window corresponding to display 360p video screen, the figure is preset 8 custom video windows, each custom video window corresponding to display 360p video screen; these custom video windows The positions are fixed and arranged or sorted according to certain rules. Taking Figure 3 as an example, the 12 custom video windows in the figure have corresponding numbers and resolutions. Similarly, the 8 custom video windows in Figure 4 are also There are corresponding numbers and resolutions.

(2) According to the set resolution of the video window, create a video window on the large window screen of the video conference interface; place the video window in a default position; wherein, the position of the video window can be dragged.

In this solution, the custom video window is to create at least one default video window at a specified position on the large window screen, where the video window is initially placed in a default position, for example, it can be placed in the center of the large window screen. The windows can be dragged at will, as shown in Figure 6. Figure 6 is a schematic diagram of the custom video window displayed in the default position. The figure shows the custom video window of 180P and 360P. These custom video windows can be dragged to move positions.

In one embodiment, for the display process of step S130, based on the situation of the two custom windows provided in the foregoing embodiment, the following two display schemes (1) and (2) can be designed accordingly. It should be noted that, These two approaches are exemplary solutions, and other types of solutions may also be used in practical applications, and the two solutions will be described below.

(1) The position of the custom video window is fixed, then the method of step S130 may include:

Obtain the sorting information of the custom video window and its window usage status; add the video picture corresponding to the concerned user to the target custom video window for display according to the sorting information and the window usage status; wherein, the target The custom video window is the unused video window with the smallest window number among the custom video windows.

Specifically, as shown in FIG. 4 , according to the order of numbers 1-12, and according to the occupied situation of the window, the video picture is added to the video window that is not used and has the smallest window number in the custom video window.

In the solution of the above embodiment, the user can add the video image of the user concerned to the video window at the fixed position according to the requirements. This solution is relatively simple to add the video image, and the video image can be directly sent to the custom video window.

As an embodiment, after the video picture is added, the video picture can also be removed from the custom video window, and accordingly, the solution of the present application can also include:

(a) Selecting any user of interest on the user list, triggering the operation of removing the user video window for the user of interest, and removing the video image of the user of interest from the custom video window.

Suppose you want to drag the picture A to the custom video window 5 that is not used (ie, the preset position 5). During the dragging process, it is judged that the window position can be changed when the condition is reached. The judgment method is: the coordinates (x1, y1) of the upper left corner of the custom video window where the screen A is located and the upper left corner coordinates of the preset position 5 ( x2, y2), calculate the straight-line distance D between the two points, when D is less than a set constant value, it can be considered that the custom video window of the current screen A meets the condition of being replaced to the preset position 5, if the condition is not met , the screen A returns to the original preset position.

In addition, the border of the custom video window can also be highlighted during the dragging process, which is convenient for viewing the dragging state in real time.

The solution of the above-mentioned embodiment provides a solution for dragging the position of the custom video window, which is convenient for users to drag the video screen to other custom video windows for display. The distance is used as a judgment. When the distance reaches the set threshold, it means that the user wants to display the video screen on the corresponding custom video window. When this condition is met, the video screen is moved to the custom video window for display.

Further, the present application also provides a solution for swapping positions of video images, and accordingly, the solution may also include:

Perform a drag operation on the video picture corresponding to the user of interest displayed in any custom video window of the video conference interface; when dragging the video picture to the video picture setting corresponding to the user of interest displayed in another custom video window. When the distance is fixed, the positions of the video images corresponding to the concerned users of the two custom video windows are exchanged.

Referring to Fig. 9, Fig. 9 is a schematic diagram after the positions of the video pictures are exchanged; on the basis of Fig. 7(a), drag picture A to the position of picture B, use the distance as a trigger condition, and trigger picture A and picture B sends a position exchange, and the result is shown in Figure 9.

In the above-mentioned embodiment, when dragging a video picture onto another custom video window, it is considered that the user wants to exchange the video picture of the custom video window, and thus the video window position exchange operation is performed.
