Bitmapdata + Flash Media Server 3

Question

I could not make streaming bitmapdata using Flash Media
Server 3.
I am using the default connection, and continues giving the
same issue of conversion.
This code:
private function init():void
if(nc){
nc.close()
nc = new NetConnection();
NetConnection.defaultObjectEncoding =
flash.net.ObjectEncoding.AMF3;
nc.addEventListener( NetStatusEvent.NET_STATUS, netStatus );
nc.connect("rtmp://localhost/fmsdemo/demo", "demo");
private function netStatus( event:NetStatusEvent ):void
switch( event.info.code ) {
case "NetConnection.Connect.Success":
_labelStatus.text = "Status: Conexão realizada com
sucesso!";
nc.client = this;
users_so = SharedObject.getRemote("users_so", nc.uri, true);
users_so.addEventListener( SyncEvent.SYNC, usersSyncHandler
users_so.connect( nc );
users_so.client = this;
break;

Hello :)
You must try to transform your BitmapData in ByteArray ...
you dispatch
your ByteArray to the server... and when you receive the
ByteArray to
the server you transform your ByteArray in BitmapData ;)
See the code source in my French article about AMF3 and
classmapping
with FMS3 :
http://www.ekameleon.net/blog/index.php?2008/01/27/92--fmis3-flash-media-interactive-serve r-3-amf3-and-classmapping
To transform un objet in ByteArray i use the code :
var buffer:ByteArray = new ByteArray();
buffer.writeObject( myObject );
And to transform the ByteArray in a new object :
var o:* = buffer.readObject();
For me this solution is a good solution to send objects with
AMF3. AMF3
support ByteArray, XML(E4X), Number, Boolean, String, Object,
Array and
class mapping (use registerClass). I don't think AMF3 support
the
BitmapData type ?
EKA+ :)
