IMFOutputPolicy::GenerateRequiredSchemas method

Retrieves a list of the output protection systems that the output trust authority (OTA) must enforce, along with configuration data for each protection system.

Syntax


HRESULT GenerateRequiredSchemas(
  [in]  DWORD         dwAttributes,
  [in]  GUID          guidOutputSubType,
  [in]  GUID          *rgGuidProtectionSchemasSupported,
  [in]  DWORD         cProtectionSchemasSupported,
  [out] IMFCollection **ppRequiredProtectionSchemas
);

Parameters

dwAttributes [in]

Describes the output that is represented by the OTA calling this method. This value is a bitwise OR of zero or more of the following flags.

ValueMeaning
MFOUTPUTATTRIBUTE_BUS

Hardware bus.

MFOUTPUTATTRIBUTE_COMPRESSED

The output sends compressed data. If this flag is absent, the output sends uncompressed data.

MFOUTPUTATTRIBUTE_BUSIMPLEMENTATION

Reserved. Do not use.

MFOUTPUTATTRIBUTE_DIGITAL

The output sends a digital signal. If this flag is absent, the output sends an analog signal.

MFOUTPUTATTRIBUTE_NONSTANDARDIMPLEMENTATION

Reserved. Do not use.

MFOUTPUTATTRIBUTE_SOFTWARE

Reserved. Do not use.

MFOUTPUTATTRIBUTE_VIDEO

The output sends video data. If this flag is absent, the output sends audio data.

 

guidOutputSubType [in]

Indicates a specific family of output connectors that is represented by the OTA calling this method. Possible values include the following.

ValueMeaning
MFCONNECTOR_AGP

AGP bus.

MFCONNECTOR_COMPONENT

Component video.

MFCONNECTOR_COMPOSITE

Composite video.

MFCONNECTOR_D_JPN

Japanese D connector. (Connector conforming to the EIAJ RC-5237 standard.)

MFCONNECTOR_DISPLAYPORT_EMBEDDED

Embedded DisplayPort connector.

MFCONNECTOR_DISPLAYPORT_EXTERNAL

External DisplayPort connector.

MFCONNECTOR_DVI

Digital video interface (DVI) connector.

MFCONNECTOR_HDMI

High-definition multimedia interface (HDMI) connector.

MFCONNECTOR_LVDS

Low voltage differential signaling (LVDS) connector.

A connector using the LVDS interface to connect internally to a display device. The connection between the graphics adapter and the display device is permanent and not accessible to the user. Applications should not enable High-Bandwidth Digital Content Protection (HDCP) for this connector.

MFCONNECTOR_PCI

PCI bus.

MFCONNECTOR_PCI_Express

PCI Express bus.

MFCONNECTOR_PCIX

PCI-X bus.

MFCONNECTOR_SDI

Audio data sent over a connector via S/PDIF.

MFCONNECTOR_SPDIF

Serial digital interface connector.

MFCONNECTOR_SVIDEO

S-Video connector.

MFCONNECTOR_UDI_EMBEDDED

Embedded Unified Display Interface (UDI).

MFCONNECTOR_UDI_EXTERNAL

External UDI.

MFCONNECTOR_UNKNOWN

Unknown connector type. See Remarks.

MFCONNECTOR_VGA

VGA connector.

MFCONNECTOR_MIRACAST

Miracast wireless connector.

Supported in Windows 8.1 and later.

 

rgGuidProtectionSchemasSupported [in]

Pointer to an array of GUID values that specify which output protection systems are supported by the OTA that is calling this method.

cProtectionSchemasSupported [in]

Number of elements in the rgGuidProtectionSchemasSupported array.

ppRequiredProtectionSchemas [out]

Receives a pointer to the IMFCollection interface of a collection object. The caller must release the interface. Each object in the collection is an IMFOutputSchema pointer. Each IMFOutputSchema pointer defines an output protection system that the OTA must enforce.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

The video OTA returns the MFCONNECTOR_UNKNOWN connector type unless the Direct3D device is in full-screen mode. (Direct3D windowed mode is not generally a secure video mode.) You can override this behavior by implementing a custom EVR presenter that implements the IEVRTrustedVideoPlugin interface.
