Yes, the source code for bandwidth checker is in first post of this thread. You can compile your own version in the Wowza IDE to make adjustments.
Richard
Did you add the jar file to wowza/lib folder then restart Wowza, and did you add the module to Application.xml. You want to connect to the Wowza server that you added that jar to, and to the application that you added the Module to.
Richard
There is a Actionscript 3 version of ctosbwcheck in [wowza-install-dir]/examples/BWCheck/CtoSBWCheck.fla
The results of the bwcheck do vary from moment to moment, which is normal result of varying network conditions.
Richard
It should be here:
[install dir]\examples\BWChecker\client\CtoSBWCheck.fla
I’ll send it to that email too.
Richard
There is a working AS3 example here:
[wowza-install-dir]/examples/BWChecker/client/bwchecker.fla
Richard
It’s on page 2 of this thread. You have to build it in the Wowza IDE
It tests from client to server. The default one at the top tests from server to client.
Richard
I don’t understand the question. Can you explain?
Richard
I think you are talking about using Netstream.play2() and netstreaminfo object. This what is used to implement Flash Dynamic Streaming, for example JW Player’s implementation
You can search around but here is one article that looks useful
Here is how the simple, before connect method to check bandwidth
https://www.wowza.com/docs/how-to-test-server-to-client-bandwidth-for-rtmp-clients
I think that camera.setQuality() will have an affect on a stream after you do netstream.publish()
Richard
You’re English is great. Thanks for the update.
Richard
i’m having some problems with converting the BWChecker to AS3.
this is what i’ve got :
var constring="rtmp://localhost/bwcheck";
var detected_bw:String;
var counter:Number=0;
var nc:NetConnection=new NetConnection;
nc.client=this;
nc.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler );
function netStatusHandler (e:NetStatusEvent):void{
trace("Level: "+e.info.level+" Code: "+e.info.code);
if (e.info.code == "NetConnection.Connect.Success") {
trace("--- connected to: " + nc.uri); //this.uri
}
}
function onBWCheck(latency:String):Number{
trace("in onBWCheck");
return ++counter; // Serverside, just ignore any return value, For now return the call count
}
function onBWDone(kbitDown, deltaDown, deltaTime, latency):void{
trace("==>in onBW_DONE");
trace("onBWDone: kbitDown:"+kbitDown+" deltaDown:"+deltaDown+" deltaTime:"+deltaTime+" latency:"+latency);
//detected_bw = kbitDown;
nc.close();
}
nc.connect(constring, true);
stop();
and i get this as a result (haven’t changed anything to serverside code, or is it necessary that i do that?):
in onBWCheck
Level: status Code: NetConnection.Connect.Success
— connected to: rtmp://localhost/bwcheck
ok , works like a charm now. Thanks a lot !
Hi Charlie,
like balint.pelhos , I need to calculate the actual bandwidth after the stream has started without start another connection and generating an extra traffic.
I read your reply about it, but I’m not able to use IOPerformanceCounter interface like you suggested…
Is it possible have some indication or some reference how to implement it (server side and client side).
Thanks!
For using the bandwidth checker module, the instruction (posted below) asks for the FLVPlayback module to be removed. I would like to know why this needs to be done?
thanks
maple01
Configuration:
Create a folder named [install-dir]/applications/bwcheck
Create a folder named [install-dir]/conf/bwcheck
Copy [install-dir]/conf/Application.xml into new bwcheck config folder
Edit copied Application.xml file and remove the module reference to ModuleFLVPlayback and add the module reference below as the last entry in the section (it is important that it is the last entry):
A complete built version can be downloaded from here. Follow Charlie’s instructions at the top of the page to install.
Please let me know if there are any problems.
Roger.
This link is dead, can anyone help? Ive tried to compile it myself but im ignorant when it comes java. Thanks.

thanks! you guys are top notch support - jason
Hi CHarlie,
I have been trying to make the bandwidth test work before we go ahead and purchase the lincense but no luck. I work for a university and we have many extension workers with dial up connection and I have been working with Richard by email to test the bandwidth check but it seems impossible to get it done. I have the plug-in in lib folder and have appropriate video files for each bandwidth here is the code:
var bandwidthVer = “_100”;
if (detected_bw >= 800)
bandwidthVer = “_750”;
else if (detected_bw >= 550)
bandwidthVer = “_500”;
else if (detected_bw >= 300)
bandwidthVer = “_250”;
But on dial up modem still gets the the one with _750, I am soo frustrated here and want to know what am I doing wrong?
thanks ina dvance for your help.
Richard,
how do I know if bandwidthVer have default of “_750”?
thanks
The default is _100
