摘要： A computer-implemented authentication protocol is used to subvert man-in-the-middle-type attacks on communications between software components that are permitted to interoperate within a processing environment, such as a media processing environment, pursuant to one or more licenses. In one exemplary scenario, a particular application transmits to a particular media processing component (“MPC”), among other things, a cryptographically protected message including a reference to a process in which the application is running and/or a GUID that the application used to invoke the MPC. If the received process and/or GUID are verified, it is possible for in-the-clear communication to occur between the application and the MPC without man-in-the-middle subversion.

摘要： This disclosure describes methods, systems, and programming interfaces for more efficiently processing media data in a media pipeline. In one embodiment, media flow in a media system is coordinated using a media foundation transform supported by a programming interface. The programming interface generates input and output events to the requisite media system thereby permitting the media foundation transform control over when input frames are requested and received and output frames are retrieved.
