IMFTrustedOutput interface

Implemented by components that provide output trust authorities (OTAs). Any Media Foundation transform (MFT) or media sink that is designed to work within the protected media path (PMP) and also sends protected content outside the Media Foundation pipeline must implement this interface.

The policy engine uses this interface to negotiate what type of content protection should be applied to the content. Applications do not use this interface directly.


The IMFTrustedOutput interface has these methods.

Method Description
IMFTrustedOutput::GetOutputTrustAuthorityByIndex Gets an output trust authority (OTA), specified by index.
IMFTrustedOutput::GetOutputTrustAuthorityCount Gets the number of output trust authorities (OTAs) provided by this trusted output. Each OTA reports a single action.
IMFTrustedOutput::IsFinal Queries whether this output is a policy sink, meaning it handles the rights and restrictions required by the input trust authority (ITA).


If an MFT supports IMFTrustedOutput, it must expose the interface through QueryInterface. The interface applies to all of the input streams on the MFT. (There is no mechanism to return a separate IMFTrustedOutput pointer for each stream.) The MFT must apply the output policies to all of its input streams. If the MFT sends different streams to separate connectors, it must report all of the connector attributes.
