I'm trying to debbug my actionscript (AS3) code on Client side that works with Flash Media Server 4 on localhost. Everything seems fine up to that point.

However, when I'm trying to test my player with other remote streaming servers, I notice bugs because of lower bandwith transmission between the server and the player.

Is there a simple way to simulate lower bandwith with FMS4 on localhost ?

  • by config, application.xml, etc.?
  • by programmation (main.asc) ?
  • both ?

If you want to think a little outside of the box, you could use an application such as NetLimiter. Just make a filter for the specific application and you can throttle the bandwidth to whatever speed you'd like (down to bytes).

EDIT

Also, with some brief googling, I was able to find client.setBandwidthLimit and BandwidthCap in the Application.xml file.

There's also an article on Configuring Limiting Bandwidth (if that helps).

  • Thank you. I tried NetLimiter 4 hours ago, but after using the software, i didn't have succeed with my tests. Maybe I use badly the software, or the version that I use don't support RMTP. i will try again tommorow. – ethiers Jan 14 '11 at 03:29

In accordance with this article "Configuring Limiting Bandwidth" (see link above - thank Brad Christie) i choose to go with Server-Side ActionScript (SSAS) way. More simple, i think.

Well, here the step what i did :

  1. Make a file "main.asc" et copy & paste the code below.

    more info : http://www.peachpit.com/articles/article.aspx?p=31217

    main.asc

    var bandwidth;
application.allowDebug = true;

// Application callback functions

application.onConnect = function(client, user) {

    //12800 = 100 Kbps  
    //64000 = 500 Kbps
    //131072 = 1Mbps
    //327680 = 2.5 Mbps
    //983040 = 7.5 Mbps
    //1966080 = 15 Mbps 
    //3932160 = 30 Mbps 
    //6553600 = 50 Mbps 
    //15728640 = 120 Mbps

    bandwidth = 64000;

    client.setBandwidthLimit(bandwidth, bandwidth); 

    trace("clientToServer = " + client.getBandwidthLimit(0) +  " serverToClient="+  client.getBandwidthLimit(1));

    application.acceptConnection(client);

    trace("17 janvier TEST");
}

  2. Save the file under the folder underneath FMS's applications directory

    Example : FMS\application\dyn

  3. Start the FMS server. If there is a problem, check the log file

    Example : FMS\logs_defaultVHost_\dyn_definst_\application.00.log

  4. (optional) Change the value ofthe variable bandwidth for your test. I put in comment some common internet connection speed converted in bytes.
