Changing to “live” only increases the delay. “live-lowlatency” is desing to reduce the delay, something that I could achieve, but by some reason the player doesn’t sustain that for long. ---

I did… I’m sending at 300kbps which is way lower than what I need (700 or more) It’s weird because at the beginning it looks just fine, than after 5 minutes it’s on 3 sec delay and it keep rising over time, but when I stop and play it goes back to normal. ---

I was wrong, it’s not the player. I’ve tried with another player (moyea FLV player for windows) and the problem persist. When I start the broadcast I got very low latency, after a few minutes it goes up. I’ve also tried running wowza from another machine (my macpro 8 core), got the same problem. Must be some settings on wowza… does anyone know why is this happening? thank you. ---

Hi Charlie. If I try to do this, the video gets choppy, it doesn’t play smooth. ---

Ok, I’ll try that. But FMLE is not buffering, that should be a indication that everything is working fine, right? ---

Hi Richard, I did the BWCheck, looks ok. But I can only test the Download. I searched on the forum for a upload BWCheck, and I found that the CtoSBWCheck.html should do it, but when I open it I only got a blank page. Do you know what’s happening ? thank you. ---

Hi Richard, there’s a link on the “rogerlittin” post, but it’s broken. Besides that there’s only actionscripts codes that I don’t know to deal with. thank you ---

Richard, most of the time I’m doing live video streaming with FMLE, and sometimes I’m overseas. So It’s really important to know how much upload bandwidth I can get from the FMLE to the Server. This way I can precisely define which bitrate to use. ---

Richard, thank you very much for your help, I appreciate that. I’ve downloaded the Modules, and added the line to the /conf/bwcheck/Application.xml Modules list. But I’m still not sure what should I run on the client side, on the “CtoSBWCheck.html” I’m only geting a blank screen, and on the Modules Collection folder there’s only a “LiveStudio.html” with no option to BWcheck. ---

Richard, I’ve downloaded a trial version of Flash Builder, and created a Actionscript project, but when I paste the code and run debug, I got a lot errors and a blank html pops up. I’m a complete newbie in Actionscript, so if you could (whenever you can) build the project I’ll be grateful. Thank’s a lot for your help so far. ---

Hello Richard, first of all, thank you very much for this. Now, I’m getting a few errors. Then I try to connect trough a client I get “NetConnection.Connect.Failed” The only way I got it to work was on the same computer that the server is running. And even though I can connect I get another error: "Error #2044: Unhandled AsyncErrorEvent:. text=Error #2095: flash.net.NetConnection was unable to invoke callback onBWDone. error=ReferenceError: Error #1069: Property onBWDone not found on flash.net.NetConnection and there is no default value. at cbwc/mainInit() at ClientBWCheck/\_\_\_ClientBWCheck\_Button1\_click()" ---

I’ve deleted everything from the last BWChecker original example. And now I don’t the that error any more. But I still can’t connect from a computer on another network, I can only connect from the same computer that is running the server. My server is up and running now, if you like to make a test. ---

I just did that on the server, But I don’t have to do this on the client side right? On the remote computer I should only run the .html and connect trough the right rtmp://ipaddress:1935/upbwcheck It’s wired because the FMLE is connecting just fine to Wowza, but when I run the ClientBWCheck.html I always get “NetConnection.Connected.Failed” ---

Richard, I’ve tried everything, checked my firewall, changed network connection, tried without my router (plugged the server straight to the modem, to a public IP). But notting happens. Every application works just fine, live, rtplive, and eve the old BWcheck works. I figure that must be a problem on the client, because as soon as I click “Connect” it gives me the “NetConnection.Connect.Failed” It look like it doesn’t even try to connect. And on Wowza screen it doesn’t show a connection attempt either. but again, this only happens when I try to run the client from a remote computer, when I do it from the same machine that the server is running, it connects. Have you tried to connect the client from a remote computer to the server? Thank you. ---

Richard, I’ve kind fixed it. It’s not a definitive solution, but at least I’ve made it work. Here is how: Putted everything that is on the article on Flash Builder and on “cbwc.as” I’ve edited the line 66 replacing the: nc.connect(“rtmp://localhost:1935/upbwcheck”); to my server IP nc.connect(“rtmp://xxx.xxx.xx.xxx:1935/upbwcheck”); Now on the ClientBWCheck.html I replace the “rtmp://localhost:1935/upbwcheck” to “rtmp://xxx.xxx.xx.xxx:1935/upbwcheck” and it works! But of course If I want to connect to another server I’ll have to compile everything again on Flash Builder with the IP of the new server. Hope that works. Thanks a lot for your help!
