May be one of the following values:
|VMR_RENDER_DEVICE_OVERLAY||The VMR will render to the overlay surface (VMR-7 only).|
|VMR_RENDER_DEVICE_VIDMEM||The VMR will render to video memory.|
|VMR_RENDER_DEVICE_SYSMEM||The VMR will render to system memory (VMR-7 only).|
This event is sent by both the VMR-7 and the VMR-9 and it is forwarded to applications. Note that the VMR-9 only supports video memory render targets.
