/* The following is a short description of the AVI file format.  Please
 * see the accompanying documentation for a full explanation.
 *
 * An AVI file is the following RIFF form:
 *
 *	RIFF('AVI' 
 *	      LIST('hdrl'
 *		    avih(<MainAVIHeader>)
 *                  LIST ('strl'
 *                      strh(<Stream header>)
 *                      strf(<Stream format>)
 *                      ... additional header data
 *            LIST('movi'	 
 *      	  { LIST('rec' 
 *      		      SubChunk...
 *      		   )
 *      	      | SubChunk } ....	    
 *            )
 *            [ <AVIIndex> ]
 *      )
 *
 *	The main file header specifies how many streams are present.  For
 *	each one, there must be a stream header chunk and a stream format
 *	chunk, enlosed in a 'strl' LIST chunk.  The 'strf' chunk contains
 *	type-specific format information; for a video stream, this should
 *	be a BITMAPINFO structure, including palette.  For an audio stream,
 *	this should be a WAVEFORMAT (or PCMWAVEFORMAT) structure.
 *
 *	The actual data is contained in subchunks within the 'movi' LIST 
 *	chunk.  The first two characters of each data chunk are the
 *	stream number with which that data is associated.
 *
 *	Some defined chunk types:
 *           Video Streams:
 *                  ##db:	RGB DIB bits
 *                  ##dc:	RLE8 compressed DIB bits
 *                  ##pc:	Palette Change
 *
 *           Audio Streams:
 *                  ##wb:	waveform audio bytes
 *
 * The grouping into LIST 'rec' chunks implies only that the contents of
 *   the chunk should be read into memory at the same time.  This
 *   grouping is used for files specifically intended to be played from 
 *   CD-ROM.
 *
 * The index chunk at the end of the file should contain one entry for 
 *   each data chunk in the file.
 *       
 * Limitations for the current software:
 *	Only one video stream and one audio stream are allowed.
 *	The streams must start at the beginning of the file.
 *
 * 
 * To register codec types please obtain a copy of the Multimedia
 * Developer Registration Kit from:

 *  Multimedia Systems Group
 *  Product Marketing

 *
 ***************************************************************************/

#ifndef NOMCIWND
#ifdef _WIN32
/*----------------------------------------------------------------------------*\
 *
 *  MCIWnd
 *
 *    MCIWnd window class header file.
 *
 *    the MCIWnd window class is a window class for controling MCI devices
 *    MCI devices include, wave files, midi files, AVI Video, cd audio,
 *    vcr, video disc, and others..
 *
 *    to learn more about MCI and mci command sets see the
 *    "Microsoft Multimedia Programmers's guide" in the Win31 SDK
 *
 *    the easiest use of the MCIWnd class is like so:
 *
 *          hwnd = MCIWndCreate(hwndParent, hInstance, 0, "chimes.wav");
 *          ...
 *          MCIWndPlay(hwnd);
 *          MCIWndStop(hwnd);
 *          MCIWndPause(hwnd);
 *          ....
 *          MCIWndDestroy(hwnd);
 *
 *    this will create a window with a play/pause, stop and a playbar
 *    and start the wave file playing.
 *
 *    mciwnd.h defines macros for all the most common MCI commands, but
 *    any string command can be used if needed.
 *
 *    Note: unlike the mciSendString() API, no alias or file name needs
 *    to be specifed, since the device to use is implied by the window handle.
 *
 *          MCIWndSendString(hwnd, "setaudio stream to 2");
 *
 *    (C) Copyright Microsoft Corp. 1991-1995.  All rights reserved.
 *
 * WIN32:
 *
 *    MCIWnd supports both ansi and unicode interfaces. For any message that
 *    takes or returns a text string, two versions of the message are defined,
 *    appended with A or W for Ansi or Wide Char. The message or api itself
 *    is defined to be one or other of these depending on whether you have
 *    UNICODE defined in your application.
 *    Thus for the api MCIWndCreate, there are in fact two apis,
 *    MCIWndCreateA and MCIWndCreateW. If you call MCIWndCreate, this will be
 *    re-routed to MCIWndCreateA unless UNICODE is defined when building your
 *    application. In any one application, you can mix calls to the
 *    Ansi and Unicode entrypoints.
 *
 *    If you use SendMessage instead of the macros below such as MCIWndOpen(),
 *    you will see that the messages have changed for WIN32, to support Ansi
 *    and Unicode entrypoints. In particular, MCI_OPEN has been replaced by
 *    MCWNDM_OPENA, or MCIWNDM_OPENW (MCIWNDM_OPEN is defined to be one or
 *    other of these).
 *
 *    Also, note that the WIN32 implementation of MCIWnd uses UNICODE
 *    so all apis and messages supporting ANSI strings do so by mapping them
 *    UNICODE strings and then calling the corresponding UNICODE entrypoint.
