FAMILYCAM Flash Video Player 

File:			FamilyCamPlayer.js
Copyright: 		(c)2008 familycam.com
Author: 		Stephen Beattie <snbeattie@gmail.com>, www.stephenbeattie.com

Dependencies:	
	SWFObject v2.0 for plugin detection and 'ExpressInstall' player upgrade option

Javascript Usage:

1. 	Include "swfobject.js" and "FamilyCamPlayer.js" (this file) in the HEAD of your HTML.  SWFObject must be included first.

2.	Create a container DIV element in your HTML containing fallback content if Javascript/Flash is unavailable in the user's browser

		<div id="myDIV">This content will be replaced by javascript....</div>

3.	Add the following Javascript code after your nominated container DIV (example using full array of available startup parameters):
	N.B. The path to the player SWF must also be supplied as a constructor argument. 
	
		<script language="javascript">	
			var player = new FamilyCamPlayer( '../path/to/player.swf', 'myDIV', 512, 330, {	// Mandatory constructor arguments
				file: 'rtmp://localhost/vod/mp4:transformers-tlr4_720p.mp4',	// Mandatory - NO DEFAULT
				starttime: '00:01:03',								// Optional - default 0 (seconds)
				autoplay: false,									// Optional - default true (boolean)
				volume: 50,										// Optional - default 75 (%)
				buffersize: 20 									// Optional - default 15 (seconds)
				hardwarescaling: false								// Optional - default true (boolean)
				videosmoothing: true								// Optional - default true (boolean)
				showlogo: false									// Optional - default true (boolean)
			});
		</script>
	
4.	After page load, you can then use the following Javascript calls from buttons, links etc. to manipulate the flash player:

		player.play();
		player.setVolume(85);
		player.seek('00:25.32'); // or seek(25);
		player.pause();
		alert( player.getCurrentTime() );

N.B.	See source below for full list and usage of external player API
