Video transmission method, conferencing system, and storage media

A conferencing system, comprising an interactive board and a wireless screen sharing device, wherein the interactive board comprises a camera head and a screen sharing receiving device, and the camera head is used to collect original video data;

• the screen sharing receiving device is used to transmit the original video data collected by the camera head;
• the wireless screen sharing device is connected to a client device, and the client device is installed with conferencing software;
• the wireless screen sharing device is configured to create a camera peripheral device, and the camera peripheral device corresponds to the camera head;
• when it is recognized that the client device is running a decoding application,
• the wireless screen sharing device is configured to:
• transmit first notification information to the screen sharing receiving device;
• the screen sharing receiving device is configured to:
• encode received original video data based on the first notification information to obtain video data in a first data format;
• and
• transmit the video data in the first data format to the wireless screen sharing device;
• the wireless screen sharing device is configured to:
• transmit received video data in the first data format to the decoding application, wherein the decoding application is used to process the received video data in the first data format based on a data format supported by the client device to obtain the video data in a second data format;
• receive the video data in the second data format;
• and
• present the video data in the second data format to the conferencing software through the camera peripheral device;
• or
• when it is recognized that the client device is not running the decoding application,
• the wireless screen sharing device is configured to:
• transmit second notification information to the screen sharing receiving device;
• the screen sharing receiving device is configured to:
• based on the second notification information, process the received original video data based on the data format supported by the client device to acquire video data in a third data format;
• transmit the video data in the third data format to the wireless screen sharing device;
• the wireless screen sharing device is configured to:
• receive the video data in the second data format;
• and
• present the video data to the conferencing software through the camera peripheral device.

A non-transitory storage medium comprising computer executable instructions, wherein the computer executable instructions, when executed by at least one computer processor, cause a wireless screen sharing device comprising an interface to perform operations, wherein the wireless screen sharing device does not have video decoding capability, the wireless screen sharing device is used to be connected with a screen sharing receiving device, and the screen sharing receiving device is connected to a camera head for receiving original video data transmitted by the camera head;

• and the operations comprising:
• connecting with a client device through the interface and identifying whether the client device is running a decoding application, where the client device is installed with conferencing software;
• configuring the interface to create a camera peripheral device;
• when it is recognized that the client device is running a decoding application, transmitting first notification information to the screen sharing receiving device, wherein the first notification information is used to instruct the screen sharing receiving device to encode received original video data based on the first notification information to obtain video data in a first data format;
• receiving the video data in the first data format;
• and
• transmitting the video data in the first data format to the decoding application, wherein the decoding application is used to process received video data in the first data format based on a data format supported by the client device to acquire video data in a second data format;
• receiving the video data in the second data format;
• and
• presenting the video data in the second data format to the conferencing software through the camera peripheral device;
• or
• when it is recognized that the client device is not running the decoding application, transmitting second notification information to the screen sharing receiving device, wherein the second notification information is used to notify the screen sharing receiving device to process the received original video data based on the data format supported by the client device to acquire video data in a third data format;
• and
• receiving the video data in the third data format through the camera peripheral device;
• and
• transmitting the video data in the third data format to the conferencing software through the camera peripheral device.
