13// extract different backends in different files (better yet, make backends
14// dynamically loadable...), they have nothing to do with each other and this
15// file is huge and also separate the standard contents from our code itself

91// First, when I say I "from XXX.idl", I mean I go into the COM Browser
92// ($Microsoft Visual Studio$/Common/Tools/OLEVIEW.EXE), open
93// "type libraries", open a specific type library (for quartz for example its
94// "ActiveMovie control type library (V1.0)"), save it as an .idl, compile the
95// idl using the midl compiler that comes with visual studio
96// ($Microsoft Visual Studio$/VC98/bin/midl.exe on VC6) with the /h argument
97// to make it generate stubs (a .h & .c file), then clean up the generated
98// interfaces I want with the STDMETHOD wrappers and then put them into
99// mediactrl.cpp.
100//
101// According to the MSDN docs, IMediaPlayer requires Windows 98 SE
102// or greater. NetShow is available on Windows 3.1 and I'm guessing
103// IActiveMovie is too. IMediaPlayer is essentially the Windows Media
104// Player 6.4 SDK.
105//
106// IWMP is from PlayerOCX.idl on PocketPC 2000, which uses CLSID_MediaPlayer
107// as well as the main windows line.
108//
109// Some of these are not used but are kept here for future reference anyway
