The properties are stored in the system registry:
[HKEY_CURRENT_USER\SOFTWARE\Medialooks\MPlatform\MLive]
and can be set with the PropsSet method. Please refer to this article about prefixes for properties.

| gpu.rgb_transform_matrix | The default color tranformation matrix for the GPU mode | |
| device.update_count | false | Once enabled, a list of available devices is updated each time you call the DeviceGetCount method. It is useful when you work with devices that can be plugged in and out the system, for example, web cameras. |
| device.set_first | false | Once enabled, the 1st available device is set the moment you create an MLive object. |
| directshow.supported | true | Once enabled, DirectShow sources are available in MLive object. |
| webcapture.enabled | true | Enables WebCapture source |
| active_frc | dword:00000002 | Sets active frame rate converter mode. |
| on_frame.sync | false | Makes OnFrame and OnFrameSafe events synchronous, so frame grabbing process won't continue until OnFrame event isn't over. |
| on_frame.data | false | Enables objects of OnFrame and OnFrameSafe events to contain MFrame data. |
| on_event.sync | false | Makes OnEvent and OnEventSafe events synchronous, so frame grabbing process won't continue until OnFrame event isn't over. |
| events.use_window | true | Use events (OnFrame, OnEvent, OnEventSafe and OnFrameSafe) in the thread of your application. If you use a service or an application without windows, then disable this mode. |
| external_access | true | Once enabled, you can use MLive objects in external applications through mp:// links and IMSenders. |
| default_name | MLive |
Default name of the object. If you need to change it, use the following approach: m_objLive.PropsSet("default_name", "new_name"); m_objLive.ObjectNameSet("new_name"); Note, that it's possible to change the name only before the object is started. If the object is running, stop it, and only then rename the object. |
