IRenderingControl::GetGreenVideoBlackLevel (Windows CE 5.0)
This method returns the green video black-level setting of this RenderingControl instance.
virtual DWORD GetGreenVideoBlackLevel( unsigned short* pGreenVideoBlackLevel) = 0;
Parameters
- pGreenVideoBlackLevel
[in, out] Green video black-level setting of this RenderingControl instance. Corresponds to the GreenVideoBlackLevel state variable.
Return Values
Custom implementations can return appropriate error codes. Should return SUCCESS_AV if the method succeeds. Otherwise, should return an error code defined in WinError.h or UPnP.h, or one of the UPnP AV-specific return values specified in UPnPAVError, especially the following errors documented for this action in the RenderingControl DCP documentation:
- ERROR_AV_UPNP_ACTION_FAILED
- ERROR_AV_UPNP_RC_INVALID_INSTANCE_ID
Remarks
This method corresponds to the RenderingControl service's GetGreenVideoBlackLevel action.
The RenderingControl service does not require that this method be implemented. The IRenderingControlImpl class therefore overrides this method to return ERROR_AV_UPNP_INVALID_ACTION.
For more information about the actions in the RenderingControl service, see UPnP AV DCP Documentation.
Requirements
OS Versions: Windows CE 5.0 and later.
Header: Av_upnp.h.
