COPP_HDCP_Protection_Level enumeration (dxva9typ.h)

  • Article

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]

Specifies the HDCP protection level.

Syntax

typedef enum _COPP_HDCP_Protection_Level {
  COPP_HDCP_Level0 = 0,
  COPP_HDCP_LevelMin,
  COPP_HDCP_Level1 = 1,
  COPP_HDCP_LevelMax,
  COPP_HDCP_ForceDWORD = 0x7fffffff
} COPP_HDCP_Protection_Level;

Constants

 
COPP_HDCP_Level0
Value: 0
HDCP protection is not enabled. See Remarks.
COPP_HDCP_LevelMin
Minimum HDCP level. Equivalent to COPP_HDCP_Level0.
COPP_HDCP_Level1
Value: 1
HDCP is enabled.
COPP_HDCP_LevelMax
Maximum HDCP level. Equivalent to COPP_HDCP_Level1.
COPP_HDCP_ForceDWORD
Value: 0x7fffffff
Reserved.

Remarks

Some televisions do not have robust support for switching HDCP protection on and off. Because of this limitation, the graphics driver might leave HDCP enabled when the application sets the protection level to zero. If the application sets the HDCP level to zero, therefore, it might receive a COPP status message indicating that HDCP is still enabled. This is not an error.
