Video Interaction (Client Camera Passthrough)

Video interaction (client camera passthrough) requires the following setup:

## Step 1: Install the Virtual Camera Driver

On each rendering node:
1. Navigate to `Larkxr-render/RenderServer/runtime/vcam`.
2. Run `RegVCam.bat` as **Administrator**.
3. Verify the installation by checking the prompt messages.

## Step 2: Obtain Authorization

Apply for a video input authorization code from the developer platform, or contact Pingxing Cloud Business to obtain it.

## Step 3: Enable Video Input in the Application

In the application settings, enable the **Start Client Video Input** option.

## Step 4: Prepare the Camera

Ensure the client device has a camera (built-in or external). No additional setup is required for devices with a built-in camera.

## Step 5: Enable Video Functionality

Access the application via `localhost` or a configured HTTPS environment. Video input is only available in a secure context.

> **Note:** For local debugging, you can configure a self-signed HTTPS environment using OpenSSL with Nginx.
