// Purpose: ActiveMovie/WMP6/PocketPC 2000 Media Backend for Windows

// TODO: Actually test HTTP proxies...
//-----------------Introduction----------------------------------------------
// This is the media backend for Windows Media Player 6 and ActiveMovie.
//
// We use a combination of the WMP 6 IMediaPlayer interface as well as the
// ActiveMovie interface IActiveMovie.
//
// For supporting HTTP proxies and such we query the media player
// interface (IActiveMovie) for the INSPlay (NetShow) interface.
//
// The IMediaPlayer/IActiveMovie are rather clean and straightforward
// interfaces that are fairly simplistic.
//
// Docs for IMediaPlayer are at
// http://msdn.microsoft.com/library/en-us/wmp6sdk/htm/microsoftwindowsmediaplayercontrolversion64sdk.asp

// "type libraries", open a specific type library (for quartz for example its
// "ActiveMovie control type library (V1.0)"), save it as an .idl, compile the
// idl using the midl compiler that comes with visual studio with the /h
// argument to make it generate stubs (a .h & .c file), then clean up the
// generated interfaces I want with the STDMETHOD wrappers and then put them
// into mediactrl.cpp.
//
// Some of these are not used but are kept here for future reference anyway
