AMCOPPStatusInput structure (strmif.h)

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The AMCOPPStatusInput structure contains a Certified Output Protection Protocol (COPP) status request.

Syntax

typedef struct _AMCOPPStatusInput {
  GUID  rApp;
  GUID  guidStatusRequestID;
  DWORD dwSequence;
  DWORD cbSizeData;
  BYTE  StatusData[4056];
} AMCOPPStatusInput, *LPAMCOPPStatusInput;

Members

rApp

128-bit random number.

guidStatusRequestID

GUID that defines the status request.

dwSequence

Sequence number. The application must keep a running count of the COPP status requests issued. For each request, increment the sequence number by one.

cbSizeData

Number of bytes of valid data in the StatusData member.

StatusData[4056]

Data for the status request. The meaning of the data depends on the request.

Remarks

The following COPP status requests are defined.

GUID	Description
DXVA_COPPQueryConnectorType	Returns the type of physical connector to the output device.
DXVA_COPPQueryProtectionType	Returns the available protection mechanisms for the physical connector.
DXVA_COPPQueryLocalProtectionLevel	Returns the protection level that is currently set through the COPP mechanism in the context of this session.
DXVA_COPPQueryGlobalProtectionLevel	Returns the actual protection level that is currently set for the physical connector.
DXVA_COPPQueryDisplayData	Returns information describing the signal that is being transmitted over the connector associated with the COPP device.
DXVA_COPPQueryHDCPKeyData	Returns the High-bandwidth Digital Content Protection (HDCP) characteristics of the output device.
DXVA_COPPQueryBusData	Returns information about the type of bus used by the graphics hardware associated with this COPP device.
