streaming video at 640x480

Hello
I am using flash 8.0 and I want to improve video quality at receiving side.


Sending side action script code is :

sending.fla:--
var nc:NetConnection = new NetConnection();
nc.connect("rtmp:/server path/application1"); //we are using influxis server
mycam = Camera.get();
mycam.setQuality(0, 80);
mycam.setMode(320, 240, 30);
send_video.smoothing = true; //send_video is video object
send_video.attachVideo(mycam);
var out_netstream:NetStream = new NetStream(nc);
out_netstream.attachVideo(mycam);
out_netstream.publish("livevideofile", "record");

and recieving side code is :


recieving.fla:--


var nc:NetConnection = new NetConnection();
nc.connect("rtmp:/server path/application1");
var in_netstream = new NetStream(nc);
rcv_video._width=640; // rce_video is video object
rcv_video._height=480;
rcv_video.smoothing = true;
in_netstream.play("livevideofile");
rcv_video.attachVideo(in_netstream);

receiving video seems to be pixellised.
So any body has experience of streaming video at 640x480?
It’s urgent.

Thanks in advance
