Video interaction

1. Open the Larkxr-render/RenderServer/runtime/vcam folder on the server.

2. Run the RegVCam.bat script with administrator privileges to ensure that each rendering node performs this operation.

3. Confirm the successful installation by referring to the prompt messages.

**Step Two: Obtain Video Input Authorization**

- Apply for an authorization code from the developer platform or contact Pingxing Cloud Business to obtain video input authorization.

**Step Three: Configure Video-Supporting Applications**

- Ensure that the required applications support video functionality and enable the "Start Client Video Input" option in the settings.

**Step Four: Prepare the Camera**

- The client needs to prepare a camera; no additional preparation is required if the device has a built-in camera.

**Step Five: Enable Video Functionality**

- Once you have set up an HTTPS environment or accessed the application via localhost, you can enable the video functionality.

By following these optimizations, users can have a clearer understanding of the key operations in each step, facilitating a smoother use of the client video input feature.

**Note:**

- For local debugging, you can set up a free HTTPS environment using OpenSSL. Below are brief steps for configuring HTTPS on Nginx and example commands for generating certificates (applicable to Windows and Linux systems).

### Example OpenSSL Certificate Generation Commands:

#### Windows：

```html
openssl genpkey -algorithm RSA -out mykey.pem -pkeyopt rsa_keygen_bits:2048
openssl req -new -x509 -days 3650 -key mykey.pem -out mycert.pem -subj "/C=US/ST=State/L=City/O=Organization/OU=Department/CN=CommonName"
```

#### Linux：

```html
openssl genpkey -algorithm RSA -out private_key.pem -pkeyopt rsa_keygen_bits:2048
openssl req -new -x509 -key private_key.pem -out certificate.pem -days 365
```

#### Nginx：

```html
server {
    listen       {{port}} ssl;
    server_name localhost;
    ssl_certificate      /path/to/cert.pem;  # 证书文件路径
    ssl_certificate_key  /path/to/key.pem;   # 私钥文件路径
    ssl_session_cache shared:SSL:1m;
    ssl_session_timeout 5m;
    ssl_protocols SSLv2 SSLv3 TLSv1 TLSv1.2;
    ...
}

```
