Description

LckMediator is an internal static class that coordinates the registration and lookup of cameras (ILckCamera) and monitors (ILckMonitor) within LCK. It maintains collections of active cameras and monitors, raises events when they are registered or unregistered, and provides lookup helpers by ID. It also forwards monitor-to-camera assignments to downstream systems, such as mixers.

​
Usage

LckMediator is typically used indirectly by components like LckCamera and LckMonitor, which register and unregister themselves automatically during their lifecycle.

​
Example: manually registering a custom ILckCamera implementation

var customCamera = new CustomLckCamera(); 
LckMediator.RegisterCamera(customCamera);

var foundCamera = LckMediator.GetCameraById(customCamera.CameraId);
if (foundCamera != null)
    Debug.Log($"Camera {foundCamera.CameraId} is registered.");

// When cleaning up
LckMediator.UnregisterCamera(customCamera);

​
Example: reacting to camera/monitor registration events

LckMediator.CameraRegistered += cam =>
    Debug.Log($"Camera registered: {cam.CameraId}");

LckMediator.MonitorRegistered += mon =>
    Debug.Log($"Monitor registered: {mon.MonitorId}");
