Referring to fig. 1 and 3, the present invention provides a method for controlling a shared camera, which is applied to a conference terminal, wherein the conference terminal includes a basic functional module in conference work, and the basic functional module includes a display screen, a speaker, a processing module, and a camera. The shared camera control method provided by the invention is mainly applied to the situation that the camera of the conference terminal fails, and specifically comprises the following steps:
s1, responding to a preset working state, and opening a virtual camera; specifically, the preset working state generally refers to the situation that the camera fails, so that the virtual camera can be automatically opened to connect with the equipment end capable of sharing the camera once the camera fails.

responding to a handshake instruction sent by the target sharing camera, and acquiring equipment information of the corresponding target sharing camera through an mDNS server;
and receiving an adjustment instruction sent by the target sharing camera, and executing a camera replacement operation according to the adjustment instruction. Further, the mode of sending the instruction to the target sharing camera includes one-key triggering (i.e. a function key is arranged in the target sharing camera, the handshake instruction can be triggered once pressed, so that the conference terminal in a preset range can receive the handshake instruction), and approach triggering (i.e. handshake interaction can be realized by approaching the preset position of the target sharing camera to the preset position of the conference terminal, and the handshake instruction is transmitted to the conference terminal), so that the camera can be quickly and automatically adjusted.
S2, determining a target sharing camera in one or more mobile terminals based on the virtual camera, and constructing a data transmission channel with the target sharing camera; in this embodiment, the target sharing camera is a target device selected from a plurality of mobile terminals, where the mobile terminals include smart devices such as a mobile phone and a tablet, and may also be a dedicated sharing camera.

In this embodiment, the overall system is deployed based on a C/S structure, and based on the same network, the target sharing camera may be based on a conference large screen platform, provide a connection port and issue mDNS services to the outside, so that clients of other platforms (Windows, mac, linux) find the issued sharing camera device of mDNS. The mDNS service issued by the target shared camera server contains the following information host IP address, mac address, and device version number information. The conference terminal discovers the target shared camera equipment through the mDNS (network discovery service), then inquires the information carried by the equipment through the mDNS, initiates network connection, supports to use TCP/UDP based on RTSP protocol (see figure), and transmits data by default using UDP.
And S3, acquiring video stream data transmitted by the target sharing camera through the virtual camera, and using the video stream data as shooting data.

When the negotiation is completed by using the RTSP based on the constructed data transmission channel, the data transmission can be performed, the server encodes the original data (NV 12, NV21 and the like) of the camera into YUV420 and transmits the YUV420 back to the conference terminal, the client decodes the YUV420 data, converts the YUV420 data into the NV12 data format and provides the YUV420 data to the virtual camera (Softcam) for displaying the picture, and the virtual camera can be used for any software (such as a Tencentrated conference) needing the camera. The virtual camera which discovers service connection based on MDSN generates and encodes the original data (NV 12/NV 21) into YUV420, and decodes the YUV420 into NV12, thereby being beneficial to data transmission.
When the conference terminal is in a preset working state in the use process, the virtual camera is used for constructing a data transmission channel with the target sharing camera, so that shooting tasks can be completed through the target sharing camera, the shooting tasks are completed automatically, the manual participation is low, the use efficiency of the camera is greatly improved, and the user experience is improved.

Further, as a preferred solution, in this embodiment, after the data transmission channel is successfully constructed, the method further includes:
sending request data to the target sharing camera; and enabling the target sharing camera to open the shooting authority to the conference terminal based on the request data. In this embodiment, the design is specific to smart devices such as mobile phones, that is, the conference terminal can only be used after the smart devices need to open corresponding functional rights, so that the security of the smart devices is fully ensured.
