//
//	Media Player Library - Cross browser / Cross player library.
//	(c) 2001-2003  Interactive Video Technologies
//
//	Basic classes are as follows:
//
//		MediaPlayers - Factory for generating MediaPlayer objects
//		MediaPlayer  - Instantiated once per video component on a page.
//		MediaStreams - Container holding all MediaStream objects for a MediaPlayer
//		MediaStream  - Class holding a single stream that can be displayed in a MediaPlayer
//
//	Global Variables:
//
//		WM, RM, QT - Constants for player type
//		PLAYER_xxx - Constants representing current play state
//		players    - Single global instantiation of a MediaPlayers object
//
//	NOTES:
//
//		Use players.getPlayer(name) where name is an elemID of a video object to get the player object for
//		a particular component
//

//
//  2001/2002    J.Busfield   Original creation of classes
//  10/23/2002   B.Law        Added enable_OnAuthorChange to RP RegisterEvents code to handle Akamai embedded timestamps
//  01/09/2003   B.Law        Reworked class to use more conventional way of defining a class and documented things
//  01/10/2003   B.Law        Moved a bunch of functionality in here that used to get deployed by VideoComponent.jsp
//  01/10/2003   B.Law        Made getCurrentTime and jumpToTime take into account offsets for the stream that is playing
//  01/17/2003   B.Law        Added concept of Start Time to a stream which is essentially just another offset... but not relative from stream to stream... instead it is a soft-chop value that some versions of WMP (6.4 for example) need to be aware of.
//  05/01/2003   B.Law        Added code to support Windows Media Player 9
//  05/01/2003   B.Law        Added getObjectHtml method to return HTML that should be embedded in page for this video stream.
//  05/05/2003   B.Law        Added VC_getObjectHtml method.
//  06/02/2003   B.Law        Added setScreenState method to handle full screen mode.
//  07/15/2003   B.Law        Added setVolume method.
//  07/18/2003   B.Law        Added code to handle autoSize flag for Real Videos - required changing size after clip dimensions are determined via javascript.
//  08/14/2003   J.B.         Moved SetFileName code here.
//  12/08/2003   G.Minami     Added parameter to LogEvent calls to send stats immediately so can track this event realtime
//  12/09/2003   B.Law        Added QueryString (qs) as optional parameter to AddStream. This querystring will be appended to the stream URL.
//  12/09/2003   B.Law        Added getAkamaiTokenQS(...) method to return stream querystring for Akamai authenticated stream.
//  12/16/2003   B.Law        Autosize does not work with Real/NS... can't resize an embed, and you must specify a width/height... so made Real/NS combo always use video component size.
//  12/17/2003   B.Law        Fixed problem with duration in WMP9... had to use currentMedia.duration.
//  12/17/2003   J.B.         In GetPlayState added check for ReadyState==4 before retrieving playstate for WMP 6.4
//  01/04/2003   J.B.         Added check for time<0 to jumpToTime. The offset is creating times less than 0 in some cases. This probably shouldn't be happening but this check is good just in case
//  01/13/2004   B.Law        Made so RM and WMP9 both ignore StartTime
//  01/26/2004   G.Minami     if using frames send stats LogEvent function call to first frame
//  03/02/2004   J.B.         Changed Netscape 7.1 WMP support to activex
//  03/19/2004   B.Law        Added reference to g_RealVideoDefault for default Real Player video. Using an empty string causes inconsistent errors.
//  03/19/2004   B.Law        Made Start() method use the new doPlayWhenReady() to play Real Media to fix a timing issue.
//  02/29/2004   J.B.         Changed NS7 Real video resize code in VC_setRealSize and VC_getRealHtml to act more like IE
//  04/02/2004   B.Law        Now recognizes "SDP" as a Quicktime type.
//  06/11/2004   B.Law        Moved CheckEvent code into here.
//  06/12/2004   B.Law        Added lastTime so rewind can be tracked.
//  06/15/2004   B.Law        Made doTimeWarp take into account initial values.
//  09/08/2004   B.Law        Modified VC_setRealSize to use a helper function and a setTimeout to set width/height... issue with Mozilla hanging if done inline... some kind of timing issue apparently.

URL is the URL of the stream, type is the constant WM or RM, bandwidth is a bandwidth #, relOffset is the offset in milliseconds relative to the rest of the videos in the collection, and startTime is the start time of this video clip.
	//	GetFirstStream(bandwidth) - Returns the URL of the first stream in the collection with a bandwidth <= the passed in bandwidth and of the current Media Type (RP or WMP)
	//	RegisterEventObservers() - Configures proxy applet required by Netscape to communicate with player plugins
	//	getCurrentTime() - Returns current position in video in milliseconds (taking into account various offsets)
	//	jumpToTime(time) - Jumps to the indicated time (in milliseconds) into the video
	//	getPlayState() - Returns the current state of the player
