onBWDone problem Flash Media Server with AS3

February 19th, 2008

I ran into a small problem today while testing FMS 3, and had some problems finding the solution. I eventually found it and would like to share it with you.if you get the error:

ReferenceError: Error #1069: Property onBWDone not found on StreamTest and there is no default value.

Make sure that you map your NetConnection.client to a client class or the class you are working from. Then create the method onBWDone in the target Class. :

1
2
3
4
5
6
7
8
9
10
11
12
13

private function setConnection():void
 
{
 nc = new NetConnection();
 nc.client = this;
 nc.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
 nc.addEventListener(AsyncErrorEvent.ASYNC_ERROR, onAsyncError);
 nc.addEventListener(SecurityErrorEvent.SECURITY_ERROR, onSecurityError);
 nc.connect(appURL);
}
 
public function onBWDone():void{
}

 Why is this happening?
Well if you look into the VOD application on the FMS server you will see that the application performs a BandWidth check and invokes this function on the client when it is done. You can measure the bandwidth speed in order to select a proper stream (assuming you have encoded multiple bitrates of one video). How to use this?
Take a look here.

    I was having the same error message with FMS 3. Worked around by setting client on the NetConnection instead - NetStream never complained. Thanks for the tip on defining a onBWDone method on the client - I missed this one ;)

    You’re right, I pasted the wrong part of code. The client of the netstream is mapped to the class for the onMetaData. It has to be the netconnection. I fixed the post, thanks for pointing it out.

    Environment Flashdevelop/AS3(Flex 3 SDK). Your fix worked.

    All that is needed with a onBWDone error is to add in:


    nc.client = this;

    This will cause the component to send return calls to the client.

    Thanks!
    I also had to add the nc.client = this; line in to get to work.

    Glad you got it. Flash Media Server can be tricky sometimes.
