About IMFOutputPolicy RRS feed

  • Question

  • The IMFOutputPolicy interface has this function GetMinimumGRLVersion. I was wondering what GRL this function is referring to? Is it the one ITA obtains from PEAuth.sys?

  • There is one active GRL installed on the system at a given time.  The ITA and PEAuth (as well as other components) verify the authenticity of the GRL, and use it to check if components are revoked.  IMFOutputPolicy::GetMinimumGRLVersion() allows the ITA to require a specific version of the GRL (or newer version) to be installed on the machine in order to allow playback.
