AMCOPPStatusOutput 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 AMCOPPStatusOutput structure contains the result of a Certified Output Protection Protocol (COPP) status request.

Syntax

typedef struct _AMCOPPStatusOutput {
  GUID  macKDI;
  DWORD cbSizeData;
  BYTE  COPPStatus[4076];
} AMCOPPStatusOutput, *LPAMCOPPStatusOutput;

Members

macKDI

Message Authentication Code (MAC) of the status data. The driver will use AES-based one-key CBC MAC (OMAC) to calculate this value.

cbSizeData
