IMFContentDecryptionModuleFactory::IsTypeSupported method (mfcontentdecryptionmodule.h)

Article
02/19/2025

Queries whether the specified Key System and, optionally, content type are supported.

Syntax

BOOL IsTypeSupported(
  LPCWSTR keySystem,
  LPCWSTR contentType
);

Parameters

keySystem

An LPCWSTR specifying the Key System for which support is being queried.

contentType

Optional. An LPCWSTR specifying the content type for which support is being queried. See the Remarks section for more information about this parameter.

Return value

True if the specified Key System and content type are supported; otherwise, false.

Remarks

Note

The contentType parameter is ignored by PlayReady, and so for that content protection system the return value only indicates whether the specified Key System is supported. If the specified Key System is supported, the method will return true, regardless of what value is specified for contentType. The contentType parameter may also be ignored by other content protection systems.

For information about Key Systems, see the Encrypted Media Extension specification's Key System
