The embodiment provides a mapping method of external equipment of a cloud terminal, which is used for mapping of video peripheral equipment of the cloud terminal. The execution subject of the present embodiment is a server.
As shown in fig. 1, a schematic flowchart of a mapping method for a cloud terminal external device provided in this embodiment is shown, where the method includes:
And step 102, determining the equipment type of each external equipment according to the equipment list.
And 104, generating a mapping request according to the device type of the target device.
And 105, creating a virtual device with the same device type as the target device according to the mapping request.
And 106, establishing a data logical link between the virtual device and the target device so as to transmit data between the virtual device and the target device.
Specifically, when the external device is connected to the cloud terminal, the cloud terminal may obtain a device list of all the external devices connected to the cloud terminal, where the device list may include device type identifiers corresponding to the external devices, and the cloud terminal sends the device list to the server.
After receiving the device list, the server may determine the device type of each external device according to the device list, and specifically may determine the device type according to the device type identifier corresponding to each external device. After the device type of each external device is determined, the external device in which data transmission needs to be performed using a video stream, that is, the target device, can be determined according to the device type of each external device, and thus the device type of the target device can be determined. The server can generate a mapping request according to the device type of the target device and send the mapping request to the lower layer virtual device bus driver, so that the lower layer virtual device bus driver creates a virtual device with the same device type as the target device on the virtual desktop according to the mapping request. And a data logical link between the virtual device and the target device can be established through the upper layer communication component, so that data transmission is carried out between the virtual device and the target device. Therefore, the virtual mapping of the video peripheral connected with the cloud terminal to the virtual desktop is realized, the functions of the video peripheral can be realized, and the operability of the video peripheral and the transmission efficiency of video stream data are improved.
In the mapping method for the cloud terminal external device provided in this embodiment, by obtaining the device types of all the external devices connected to the cloud terminal, it is determined whether there is a target device that needs to perform data transmission using a video stream, and according to the device type of the target device, a mapping request is generated, so that the lower layer virtual device bus driver creates a virtual device having the same device type as the target device according to the mapping request. The method and the device realize that the USB port number corresponding to the specific USB device does not need to be acquired, reduce the number of signaling transmission times, and improve the efficiency and the accuracy of determining the peripheral device type and establishing the corresponding virtual device. Meanwhile, the data logic link between the virtual equipment and the target equipment enables the operation of the virtual equipment by the server to be sent to the cloud terminal actual equipment through the data logic link, and data returned by the actual equipment can also be returned to the virtual equipment through the data logic link, so that the function of the cloud terminal video peripheral equipment is effectively realized, and the transmission rate and the real-time performance of video stream data are improved.

And step 110, receiving video stream data fed back by the cloud terminal so as to be displayed to a user through the virtual equipment.
Specifically, after a virtual device of the same type as the device of the target device is created in the virtual desktop and a logical data link between the virtual device and the actual target device is established, data transmission may be performed between the virtual device and the actual target device.
When the user operates the virtual equipment through the virtual desktop, the server can obtain a user operation instruction, converts the user operation instruction into an instruction data packet which can be transmitted by the data logic link, and then sends the instruction data packet to the cloud terminal through the data logic link.
After receiving the instruction data packet sent by the server, the cloud terminal can acquire a corresponding operation instruction according to the instruction data packet and send the operation instruction to the actual target device so as to control the target device to execute the operation and return the video stream data, and after receiving the video stream data returned by the target device, the cloud terminal feeds the video stream data back to the server.
After receiving the video stream data fed back by the cloud terminal, the server may display the video stream data to the user through the virtual device corresponding to the target device on the virtual desktop, for example, play a shot video, or display a video recording preview, or a shooting preview effect.
It should be noted that, since the video is shot at a time interval, the server may identify what operation the user operation instruction is, may be a video recording or shooting instruction, or may also be a video recording end or shooting end instruction, and the like, when it is monitored that the user sends the video recording or shooting instruction, the server may control the video peripheral to start recording or shooting through the above process, when it is monitored that the video peripheral stops recording or shooting, during or after the recording or shooting process, the video stream data is returned to the cloud terminal, and the cloud terminal may send the video stream data to the server for display or playing.
On the basis of the first embodiment, optionally, before the step 101, the method may further include:
step 201, receiving a prompt message sent by a cloud terminal for accessing an external device to the cloud terminal.
Step 202, generating a query request according to the prompt message.
Step 203, sending the query request to the cloud terminal, so that the cloud terminal obtains the device information of each external device connected with the cloud terminal according to the query request, generates a device list according to the device information, and sends the device list to the server.
Specifically, when an external device accesses the cloud terminal, the cloud terminal can monitor the external device, and then a prompt message can be generated and sent to the server.
After receiving the prompt message sent by the cloud terminal, the server can generate an inquiry request according to the prompt message and send the inquiry request to the cloud terminal.
After receiving the query request, the cloud terminal acquires device information of all external devices connected to the cloud terminal according to the query request, where the device information may include device type identifiers corresponding to the devices, and the cloud terminal may generate a device list according to the device information and send the device list to the server.
The server may then perform the above-mentioned steps 101-110 after receiving the device list.
