What return value for "MFPROTECTIONATTRIBUTE_HDCP_SRM". RRS feed

  • Question

  • I want applied HDCP for content. Then  GenerateRequiredSchemas function is create a IMFCollection instance and out.

    And then, OTA was called GetSchemaType, GetConfigurationData functions. 

    Finally! OTA was called GetBlobSize and GetBlob functions. guidKey parameter's value was "MFPROTECTIONATTRIBUTE_HDCP_SRM"

    What I set value in the pcbBlobSize, cbBufSize, pBuf, cbBufSize?

    Where was SRM data?

    Please told me... please.

  • The SRM data is defined in the HDCP specification.  You need to provide the SRM data according to that spec.

  • Thanks your answer. 

    But, I still had a problem that "ERROR_GRAPHICS_OPM_DRIVER_INTERNAL_ERROR".

    If above error was not occurred by invalid SRM data, what was problem?
