[0002] During video conferencing, with the diversity of presentation and collaboration needs, it is usually necessary to use third-party OBS streaming presentation software to achieve personalized creative expression needs. Generally, the audio and video communication between video conferencing software and OBS is based on the connection of virtual cameras, which manipulates the OBS virtual camera presentation layer to push the audio and video streams to the video conferencing software port. Limited by the system software process level, when OBS communicates with the conference software, we can generally only manipulate the top-level OBS. At this time, other capabilities that the video conferencing software level needs to express, such as text communication, voting, etc., cannot be directly exposed and called in real time. They need to be implemented through frequent software switching, which greatly reduces the presentation effect. Summary of the invention

[0028] In order to better understand the present invention, the present invention is further described below in conjunction with specific embodiments and drawings.

[0029] The video acquisition method provided in this embodiment is applicable to a video conference between at least one first video device and at least one second video device, where the first video device is, for example, a local video device and the second video device is, for example, a remote video device. The first video device is provided with at least one actual camera; the second video device can be the same video device as the first video device or a different video device. The first video device and the second video device are, for example, mobile phones, tablets, desktop computers connected to cameras, etc.

[0030] Video conferencing software is installed in both the first video device and the second video device. The video conferencing software in the first video device and the second video device interact and establish a video connection through the Internet. After the video connection is established, the first video device can transmit video data to the second video device.

[0031] Furthermore, a virtual camera is pre-installed in the first video device, and the window (screen) data of the first video device is format-converted using the virtual camera to obtain video output data, which is displayed in the window of the second video device. The virtual camera is a type of application software that can simulate a real camera.

[0032] The first video device has a first video window, the second video device has a second video window, and the video data transmitted between the first video device and the second video device includes video data acquired by a camera of the first video device and / or window data of the first video window acquired by a virtual camera.

[0033] Figure 1 A flow chart of a video acquisition method according to an embodiment of the present invention is shown. Figure 1 As shown: The method includes:

[0034] S00: Reading a first size ratio and a first coordinate parameter of at least one first video window, and a second size ratio and a second coordinate parameter of at least one second video window.

[0035] In this step, a connection is established between the virtual camera and at least one first video device and at least one second video device. Specifically, the video conferencing software in the first video device and the second video device interact and establish a video connection through the Internet.

[0036] The first size ratio and the first coordinate parameter of the first video window are read through the communication interface between the virtual camera and the first video window; the second size ratio and the second coordinate parameter of the second video window are read through the communication interface between the virtual camera and the second video window.

[0037] S10: Read parameters of interactively operable elements in different presentation modes of at least one first video window.

[0038] The first video window can realize different interactive operations in different presentation modes. Interactive elements include trigger click, drag and drop zoom, move and other elements; the parameters of interactive elements include the area coordinates of the interactive elements relative to the first video window, element size and the like.

[0039] In this step, the parameters of the interactively operable elements in different demonstration modes of the first video window are read via the communication interface between the virtual camera and the first video window.

[0040] S20: Generate a transparent operation window that can simulate interactive operations according to the read parameters of the interactively operable elements in different demonstration modes of at least one first video window.

[0043] S202: Overlaying the transparent element block with a transparent image canvas to generate a transparent operation window that can simulate interactive operations.

[0044] Among them, the area coordinates and element size of the transparent element block relative to the transparent image canvas are the same as the area coordinates and element size of the interactive element relative to the first video window.

[0045] S30: Attach the transparent operation window to the second video window.

[0046] In this step, the transparent operation window is scaled proportionally to the same height as the second video window and centered to achieve positioning fit between the transparent operation window and the second video window.

[0047] Normally, the video data and window data of the first video window transmitted by the virtual camera can only be displayed in the second video window, and interactive operations such as clicking cannot be performed; the embodiment of the present invention reads the parameters of the interactive operation elements of the first video window, simulates and generates a transparent operation window that can simulate interactive operations according to the interactive parameters, and simultaneously reads the coordinate size of the second video window, matches and fits the transparent operation window with the second video window, thereby realizing interactive operations of the second video window that receives video data.

[0048] At the same time, the embodiment of the present invention makes the virtual video stream image layer transparent, blocks the interactive elements, reads the coordinate size of the video conference software image window, matches and fits the transparent layer with the conference image layer, and then fits the interactive elements to the video conference window. It is not necessary to frequently switch the software end to control the image in the video conference and other capabilities of the conference software end.
