Receiving a stream of a NetGroup - actionscript-3

Question

I'm trying to receive a stream of a NetGroup (television) but it fails at some point. Here is the code (reduced to a testcase):
package lib
{
import flash.events.NetStatusEvent;
import flash.external.ExternalInterface;
import flash.media.SoundTransform;
import flash.media.Video;
import flash.net.GroupSpecifier;
import flash.net.NetConnection;
import flash.net.NetGroup;
import flash.net.NetStream;
import flash.net.NetStreamPlayOptions;
import mx.core.FlexGlobals;
public class player
{
private var connection:NetConnection;
private var group:NetGroup;
private var group_option:GroupSpecifier;
private var self:Object;
private var stream:NetStream;
private var stream_option:NetStreamPlayOptions;
private var video:Video;
private function _connect():void
{
self.connection = new NetConnection();
self.connection.addEventListener(NetStatusEvent.NET_STATUS, self._event_net_status);
self.connection.connect('rtmfp://p2p.peer-stream.com');
}
private function _event_net_status(event:NetStatusEvent):void
{
if(event.info.code === '')
return;
ExternalInterface.call('echo', 'status', event.info.code, false);
switch(event.info.code)
{
case 'NetConnection.Connect.Success':
self._p2p_start();
break;
case 'NetGroup.Connect.Success':
self._stream_init();
break;
case 'NetStream.Connect.Success':
self._stream_start();
break;
}
}
private function _p2p_start():void
{
self.group_option = new GroupSpecifier('G:0101010c0b0e70726f2073696562656e00');
self.group_option.ipMulticastMemberUpdatesEnabled = true;
self.group_option.multicastEnabled = true;
self.group_option.objectReplicationEnabled = true;
self.group_option.postingEnabled = true;
self.group_option.routingEnabled = true;
self.group_option.serverChannelEnabled = true;
self.group = new NetGroup(self.connection, self.group_option.groupspecWithAuthorizations());
self.group.addEventListener(NetStatusEvent.NET_STATUS, self._event_net_status);
}
private function _stream_init():void
{
self.stream = new NetStream(self.connection, self.group_option.groupspecWithAuthorizations());
self.stream.addEventListener(NetStatusEvent.NET_STATUS, self._event_net_status);
}
private function _stream_start():void
{
self.video.attachNetStream(self.stream);
self.stream.soundTransform = new SoundTransform();
self.stream_option = new NetStreamPlayOptions();
self.stream_option.streamName = 'G:0101010c0b0e70726f2073696562656e00';
self.stream.play2(self.stream_option);
}
public function player():void
{
super();
FlexGlobals.topLevelApplication.stage.quality = 'BEST';
self = this;
self.video = new Video(640, 480);
FlexGlobals.topLevelApplication.video_box.addChild(self.video);
self.video.smoothing = true;
self._connect();
}
}
}
The ExternalInterface call there shows me just the passed info in a textfield (I'm testing this in a browser). Here is the result of this output:
NetConnection.Connect.Success
NetGroup.Connect.Success
NetStream.Connect.Success
NetStream.Play.Reset
NetStream.Play.Start
But nothing happens on the player. Here are my thoughts:
I'm using the same string as GroupSpecifier and streamName but I'm assuming this is wrong. If so how can I get the stream name of the NetGroup?
I'm enabling everything from the GroupSpecifier as I don't know what are the minimum requirements to receive a stream and pass it then to another clients. Maybe enabling all makes some troubles here.
Maybe somebody can tell me how I can solve this problem to finally see a stream.

Answer 1

I was able to solve the problem: The streamName was indeed wrong and I could manually figure out the correct name. Also instead of using new GroupSpecifier() I must pass the known group-string directly to the NetGroup and NetStream object.
