Hi Experts,

I have been using an Adobe example that you can find here.

http://www.adobe.com/devnet/flashmediaserver/articles/metadata_video_streaming.html

I have made it work really well.  I now want to use the Openvdeoplayer (http://openvideoplayer.sourceforge.net/) and code in as3.  I am trying to convert the function that receives the text and shows it in a box under the player.  The original as2 function was the following.

my_ns.onDataEvent = function(str) {
   _root.display_txt.text = str;
};

I have written the following version

public function onDataEvent(str:String):void {
 display_txt.text = "test " + str;
}

But I can see that it is not listening to the stream. I thought that I should be using 'addEventListener', but I am getting nowhere.  I am using the Akamai example CS4sampleLive and I have attached both files.  They compile fine but into a nice swf but they don't pick up the data.  I am still using the orignial code in the main.asc on my fms 3.5 server and the insert.swf.

I hope that it is something simple that I am missing.

Thanks

You would need something like:
display_txt.addEventListener(DataEvent.DATA) {
display_txt.text = "test " + str;
}

However I don't believe you can pass variables to an event listener so you would have to get str from elsewhere.

Sorry more like this:

import flash.events.DataEvent;

display_txt.addEventListener(DataEvent.DATA, yourFunction);
function yourFunction(e:DataEvent):void {
      display_txt.text = "test " + str;
}

Hi,

Many thanks for this, I have added it within the last public function and it compiles correctly.  I think I understand what is going on, but will have to wait a little until I can test all the way through as I am out of the office at the moment.

Kind regards

HI,

I am happy to accept your solution and close this, but for interests sake I dug right down into the OPV code and in the end used OvpEvent.NETSTREAM_TEXTDATA which had a data type of data in my function.  So with great joy it all worked.

Hope this helps others,
