Class Program
    Friend Shared Sub Main(ByVal args As String())
        ' Create an instance of SWFToVideo ActiveX object
        Dim converter As New SWFToVideo()

        ' Set debug log

        ' Register SWFToVideo
        converter.RegistrationName = "demo"
        converter.RegistrationKey = "demo"

        ' Set the converter to the live data conversion mode
        ' (it will fully load the embedded video stream before the conversion)
        converter.SWFConversionMode = SWFConversionModeType.SWFWithLiveData

        ' set input SWF file 
        converter.InputSWFFileName = "shapes.swf"

        ' set output AVI or WMV video filename
        converter.OutputVideoFileName = "result.wmv"

        ' Don't let it run infinitely
        converter.ConversionTimeOut = 5000
        ' 5000ms = 5 seconds 
        ' set FPS 
        converter.FPS = 29.97F

        ' 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):

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

        ' Set output movie dimensions 
        converter.OutputWidth = 320
        converter.OutputHeight = 240

        ' Run the conversion

        ' Show conversion progress:

        Dim i As Integer = 0
        Dim spin As Char() = New Char() {"|"c, "/"c, "-"c, "\"c}
