If the driver setup was performed without administrative privileges, the DirectShow source filter may not be enabled.

To enable the DirectShow source filter after setting up the driver without administrative privileges, follow these steps:

1) Sign in again with an account that has administrative privileges.

2) Connect the camera and wait for the driver to be installed. It’s crucial to connect the camera at least once with an account that has administrative privileges after setting up the driver.

3) Restart Windows.

4) After restarting, sign in again with an account that has administrative privileges. At this point, the DirectShow source filter should be enabled.

After following these steps, the DirectShow source filter should be available even with an account that doesn’t have administrative privileges.
