Custom C# Control:

Note this is only part of the control. With a little more work you can easily make is so you can drop it on a page and simply name the FlashAudioVariable to point to the name of the flv.

Panel pnlAudioContainer = new Panel();
pnlAudioContainer.ID = string.Concat(this.ID, "_pnlAudioContainer");
pnlAudioContainer.Style.Add("float", "left");
pnlAudioContainer.Style.Add(HtmlTextWriterStyle.Width, "100%");
pnlAudioContainer.Style.Add(HtmlTextWriterStyle.Height, "2px");
Panel pnlAudio = new Panel();
pnlAudio.ID = string.Concat(this.ID, "_pnlAudio");
pnlAudio.Style.Add("display", "inline");
pnlAudio.Style.Add("float", "right");
pnlAudio.Style.Add("_margin-top", "-23px");
pnlAudio.Style.Add(HtmlTextWriterStyle.Width, "90px");
pnlAudio.Style.Add(HtmlTextWriterStyle.Height, "30px");

string Flashobjectstart = "<noscript><object classid=’clsid:d27cdb6e-ae6d-11cf-96b8-444553540000′ codebase=’http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,0,0′width=’90′ height=’30′ align=’middle’><param name=’movie’ value=’yourlocatointo.swf’ /><param name=’quality’ value=’high’ /><param name=’bgcolor’ value=’#FFFFFF’ /><param name=’FlashVars’ value=’myVid=rtmp://video/audio/location/";

string FlashJS1 = "<script language=’javascript’ type=’text/javascript’>FlashAudio(‘";
string FlashJS2 = "’);</script>";
string FlashAudio = string.Concat(Flashobjectstart, audioFileName, Flashobjectmid, audioFileName, Flashobjectend);
string FlashAudio2 = string.Concat(FlashJS1, audioFileName, FlashJS2);
pnlAudio.Controls.Add(new LiteralControl(FlashAudio));
pnlAudio.Controls.Add(new LiteralControl(FlashAudio2));
pnlCaptionMain.Controls.Add(pnlAudioContainer);
pnlCaptionMain.Controls.Add(pnlAudio);

Shared Object in ActionScript3 w/ FlashVars:
There are slight differences in the way the flash player 9 handles flashvars. This is a working example of how a custom flv player would use flash vars to call a video or audio file and play it! It also uses a shared object the benefit of this is its persistence (like a cookie on stereiods) if you had say several videos that you wanted to play on several different pages but you wanted the player to stop / rewind and if your user tells it to stop to remember the user told the flash player to stop here is how you would do that:

ActionScript3 SharedObject External Video / Audio in Flashvars:
import fl.video.*;
var flvControl = display;
var flashvars:Object = LoaderInfo(this.root.loaderInfo).parameters;
var flvSource = flashvars['myVid'];
flvControl.autoRewind = true;
var my_so:SharedObject = SharedObject.getLocal("userPref");
if (my_so.data.stopped == undefined) {
flvControl.play();
flvControl.autoPlay = true;
toggle_btn.gotoAndPlay(1);
} else {
flvControl.stop();
flvControl.autoPlay = false;
toggle_btn.gotoAndPlay(2);
}
function completeHandler(event:VideoEvent):void
{
flvControl.seek(0);
flvControl.play()
}
flvControl.addEventListener(VideoEvent.COMPLETE, completeHandler);
flvControl.source = flvSource;
function toggleHandler(event:MouseEvent):void
{
if( flvControl.playing ){
my_so.data.stopped = 1;
my_so.flush();
flvControl.stop();
toggle_btn.gotoAndPlay(1);
}else{
if(my_so.data.stopped == !undefined)
{
my_so.clear();
}
flvControl.play();
toggle_btn.gotoAndPlay(2)
}
}
toggle_btn.addEventListener(MouseEvent.CLICK, toggleHandler);
