• Create a new Project.

• Make sure the Components window is open.  If not, open it using Window->Components.

• Drag component from the Components window into the stage.  Resize it to the size you want.  In the next step, you can decide the scaling mode of the video, such as maintainAspectRatio or noScale.
• Open the Parameters window.  Use Properties->Parameters if it is not open.  Here you can see options that you can change to customize the player (if the window is blank, select the player movie on the stage to select it).  For example, let’s change the skin.
• Change the scaleMode if you like, if you use noScale, you need to make sure the video fits into the player.  The options are quite self explanatory.  skinAutoHide causes the player control to be hidden unless you mouse over into the player.  Double click or click the Magnifying Glass icon on the right side of skin, a dialog should pop up.  Select a skin.
• The source parameter is the most important parameters.  This is where you specify what video to play.  Enter the flv filename there.  You can pass a full URL or a relative path.

Reusing the same swf for multiple videos

You can pass the source parameter via FlashVars by writing code that reads the value and pass it to the FLVPlayback component.

• Create a document class, for example, I named mine FlvPlayer.
• Create the FlvPlayer.as file and enter the following (this assumes that I use videoFilename as the variable name for the source).

  package
  {
  	import flash.display.Sprite;
  
  	public class FlvPlayer extends Sprite
  	{
  
  		public function FlvPlayer()
  		{
  			trace("this.loaderInfo.parameters.videoFilename="+this.root.loaderInfo.parameters.videoFilename);
  			var parameters=this.loaderInfo.parameters;
  			flvPlayer.source=parameters.videoFilename;
  			if (parameters.autoPlay=="1")
  				flvPlayer.autoPlay=false;
  			else
  				flvPlayer.autoPlay=true;
  		}
  	}
  }
  

  While at it, I also added the ability to turn on or off the autoPlay.

• Then add the FlashVars into the html. For example, if I want the source to be video1.flv and no autoPlay, then the FlashVars is like this: videoFilename=video1.flv&autoPlay=0
