		' you may calculate output video duration using information about the the source swf movie
		' WARNING #1: this method to calculate the output video duration is not working for movies with dynamic scenes 
		' and interactive scripts as in these movies it is not possible to calculate the precise duration of the movie 
		' WARNING #2: you should set the input swf or flv filename (or url) before this calculation

		' So the movie duration is calculated as the following:
		' as swf frame count (number of frames in the swf) / movieFPS (frames per second defined in swf)
		' and then multiplied by 1000 (as we are setting the .ConverstionTimeout in milliseconds)
		' as the following (uncomment if you want to set the length of the output video to the same as the original swf)
		' or as the following source code (uncomment to enable):

		' swf.ConversionTimeout = 1000 * (swf.FrameCount / swf.MovieFPS)

			swf.InputSWFFileName = "test.swf"
			swf.OutputVideoFileName = "test.wmv"

			swf.SetProgressNotifyWindow(Handle.ToInt32(), WM_CONVERSION_PROGRESS, 0)
