Media Server :: RTMPT & RTMPS Only Allow A Certain Amount Of Connections From A Single Client?
May 20, 2011
I've been trying to figure out FMS for about a week now. Because of company firewalls, all traffic must go through either port 80 or 443 (I configured this in FMS.ini). I also created a self-signed SSL certificate and configured the adaptor.xml file to use it. Nevertheless, here are the problems I am experiencing: For RTMPT & RTMPTE, I can't start more than 9 connections. Beforing configuring FMS to also use port 443, I could only get about 4 connections. Now I would like to say that I testing this between only two computers, the FMS server with apache web server and a client.why it will not at least start 10 connections which I know is the limit for the dev version? Also, when using RTMPS I can only start 1 connection. Why is that?

I have been running FMIS 3.5 for about 18 months, and recently it started acting up even though I have not made any changes. After a while (sometimes days, sometimes hours), it starts rejecting new connections, but it allows existing connections to keep working. If I refresh my app, then I can't reconnect. The license I have is unlimited. Can anyone shed some light into why this is doing this and what I can do to fix it? Sometimes it happens when only a couple dozen people are online, and today it did it about 4 times with over 1500 people online.

I am willing to make an online game client-server. That is, many clients are connected on the same server, and thus interact. The application used by clients is a swf (done in flash) and runs in a browser. My questions are: 1 - I can create the server in AIR? If yes, which of the classes are recommended to do this efficiently? 2 - What classes are recommended for clients (swfs) to communicate with the server efficiently? 3 - The transfer of data between the client and the server can only be accomplished through the TCP protocol?

I have configured FMS 4.0 to do RTMPS on port 443. To test it, I created a self-signed certificate and then imported the certificate as an authority in my browser (Firefox). I don't want to go and get a real certificate until I can verify that FMS is able to do what I want it to.I included the path to the certificate and the private key in Adaptor.xml in <install dir>/conf/_defaultRoot_/That's the only file I have modified.[code]In the NET_STATUS handler I always get the following error: NetConnection.Connect.CertificateUntrustedSigner.

I've been working with the Beginning AS3 Tutorial which streams a video from Flash Media Server. I've been trying to enable RTMPS for this demo and it works correctly in Firefox and IE on Windows (usingTLS == true) but does not work (usingTLS == false) in Firefox on Linux and Chrome on Windows. Why Flash does not currently support either of these browsers? I've verified against Openssl using s_client connect that the certificate chain was properly installed from the website's wildcard certificate -> intermediate certificate -> root certificate. Why doesn't it work in all browsers on all platforms?

i have a linux machine with two NICs, one for Apache/PHP (port 80) and the other for FMS 4 (ports 1935, 80). I need to use RTMPT over port 80 due to our organization wireless network restrictions. I think i have set up everything right, but we cannot see any video using the wifi clients. Apparently, the problem disappears when opening the firewall and allowing port 1935 traffic.

1) I am trying to make connection with Flash Media Server to publish live video streaming, and I am sitting behind proxy and firewall, I am not able to make my connection with rtmp that's why I use rtmpt to make my connection with media server to publish .But in this case after publishing some time(ie 5 to 10 minutes) connection break down and streaming get stopped .The same problem occurs when I use "Flash Media Live Encoder 3" to publish live stream .
2) I am making my connection like this "rtmpt://xx.yy.zz.kk:80/Training" where xx.yy.zz.kk represent live System IP where Flash Media Server is running.
3) After analyzing the problem I observed that while publishing the stream ,http requests from Publishing system keeps on increasing and at one time it crosses the limit of proxy server (our proxy can handle 600 http requests per minute from any client PC) so streaming get stopped.
4) Then I attended "adobe connect pro" Trail classroom session by sitting behind the same proxy and firewall,But in this case my live video streaming is not breaking down ,as per my understanding adobe connect pro also use Flash Media Server for streaming.

We have a pool of FMS 3.5 servers behind a haproxy load balancer. They are working fine with RTMP and download with HTTP through FMS proxy. We need now to have RTMPT working for some clients behind a strict firewall.
1) We started configuring the haproxy load balancer to work in HTTP (level 7) mode and we changed the FMS Adaptor.xml configuration file on all servers with the tag below:

I am trying to connect to the Flash media servers from behind a customer's firewall.From behind this firewall the time taken for a response (its usually success) is around 20-25 seconds.The following is the code I am using to make the connection and listen to the events
var nc = new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS,netStatusHandler);
var time1:String = (new Date()).toTimeString();[code]........
The delay between time1 and time2 is always 20-25 seconds. From other firewalls and non firewalled networks its usually 3-4 seconds.What could be the reason for this huge delay for a response in this case. I have noticed that the first response is always a "NetConnection. Connect.Success".We are looking to deploy around 20-30 media servers if we can get this thing to work and appreciate any prompt response in this regard.

I have a setup where I have some edge servers (as in <Mode>remote</Mode>) that pull content from an origin server. I only want to allow RTMPE connections to the edge server. I'm trying to do this by using the <DisallowedProtocols> element on the origin server. I'm setting: <DisallowedProtocols>rtmp,rtmps,rtmpt</DisallowedProtocols>
in the relevant Vhost.xml on the origin server. However, when I do that, proxying through the edge server stops working. I get a "Connection attempt rejected by FMS server [ Server.Reject ] : Connection failed." from OSMFPlayer (which I'm using for testing) and these lines show up on the origin server's core.00.log file:

The attached image shows 17 client connections. Unfortunately there are not 17 clients connected to that app. In fact, I add users to a userlist shared object in application.onConnect(), and that shared object only reports 6 connections. That is the accurate number of connected users.
Why the phantom connections? Even if I unload and reload the app, the 17 client connections return.
How can my userlist shared object and the client connection number be out of sync? This situation seems to be related in some way to an FMS memory problem that is cropping up all of a sudden. When I have larger numbers of connected clients - say 300, the client connections reported in the FMS console are ten times that - like 3,000 or more. Then the application is unloaded by FMS for being a memory hog.
The app itself is simple. It just stores each user in a user array and passes chat communication to and from these users. The last time this main.asc code was changed was 2/8/2010. No problems with it in the countless times we've used it since then. Why the sudden phantom FMS connections, memory hog behavior, and constant unloading of the app?

URL...I am running application instance that implements publisher/subscriber on video streams. Application code is very thin and can be removed completetly if required. In a specific time, randomly, disconnect messages stopped happening which causes the folowing:
1. Streaming service shows decrease of bw per second
2. Users count is increasing linearly.
3. No disconnect messages apears on access.0x.log

I have FMS 4 and a videochat app (one-to-one), everything runs smoothly until about 750 users (it means about 1500 connections to fms), then I get a sudden drop in users connected to 300-400, no errors in the fms log and the cpu/memory usage is at about 25% just before this. I'm running Windows 2008 R2 Web (x64) and I've red somewhere that maybe this version of windows has some connection limit that could be the cause, but I've no idea of what could be happening.

Does FMS 3.5.2 in development impose restrictions via the origin of connections? That is, does it only allow localhost connections via ActionScript (NetConnection) or are external connections allowed?In other words, can I have FMS in dev mode on a dedicated server and then have my client code running on a different machine that opens connections to this development server?

We have a custom application that is running on FMS. Server is dedicated just for fms, there is only one application running on the server, with more instances, average traffic is 3-15 simultaneous users.The problem is,server suddenly stops accepting connections (after 1-3 days from restart), from this point it is impossible to connect to any instance, and fms server must be restarted.When the server crashes, the admin console can see all open instances, can close instances, can restart fms. There is nothing logged, that would explain this sudden failure.Second problem is, cores are connected and disconnected too often, causing client to reconnect (takes 2-5 seconds).

Live stream parameters:
320Ñ…240 qua_=87 bw_=200000 kf_=5 fps_=18
So, after approximately 600 connections to one stream video becomes choppy (periodically freeze, slow motions). CPU-usage at this time is 100-120% (maximum is 800%, 100% per each core), network usage is 500 Mbit/sec.But second live stream(with few connections) at this server looks fine simultaneously with 600 connections at first stream.Experiments with recommendation in "Configuring performance features" documentation chapter(enabling/disabling aggregate messages and configure the size of stream chunks) do not help.

It stands to reason that an OS would have a memory limit for the FMS process. I have a video chat app to which I may need to connect 300,000 or more concurrent users. Has anyone done this? Would this break the bank? What's the most you've ever had connected at once?
The video portion of my app goes through a good CDN, so I don't think there's a problem there. But my chat room is all on one FMS instance. I see something in FMS docs in "configuring performance features" that warns, "Adobe recommends that you ensure that your total system memory usage does not exceed the process limit of your OS". Granted it's in the context of configuring media cache, but wouldn't the same apply to chat room size if the numbers get high enough?

I am involved in project managment for a large video conferncing project involving over 100k simultanous connection and most likely to be increased 4 times by next six months.While figuring out the scalability area ,it was concluded that smart selection of hardware and origin-edge clustering will be suited most. Well while studying this documentation says it supports thousands of calls but unfortunately I could not determine the actual numbers. Can you tell me how many edge server will be needed for 100k simultanous calls/number of sessions per edge server and will we need license (4500$) for each edge server?

I am trying to make clients to connect FMS4 server over RTMFP for my video conferencing application.It is basically a client-server media relay application in which clients with webcam/mic connect the server and the server relays video/audio data to other clients. This application is working perfectly with FMS 3.0 but it was RTMP rather than RTMFP - I simply replaced 'RTMP' with 'RTMFP' in netConnetion and tried to test in Flash Media Development Server 4.0, but it is failed to make a connection from a client - it was working after replacing it back with 'RTMP' of course.
I believe server-client media relay is possibe using RTMFP in FMS4 because Adobe said:"Although RTMFP is often used for peer-assisted networking applications, you can use RTMFP in unicast, broadcast, and multi-point publishing applications as well. Simply replace the RTMP protocol in the NetConnection.connect() call with the RTMFP protocol:" in url...

I am trying to create a flash player to stream an on online Internet radio station using FMS. I chose FMS after being told that I need RTMP server to extract the metadata. Our radio audio is being encoded using a DJ interface called SAM Broadcaster. But for some reason, it does not have an option to send over the stream directly to a Flash Media Server. Only options are either IceCAST or ShoutCAST. How should i setup the stream? Should it be Stream encoder>> IceCAST/SHOUTCast Server>>Flash Media Server>>Flash Player Client. Or should I setup Stream Encoder>>Flash Media Server>>Flash Player Client? Shouldn't Flash Media Server be an alternative to IceCast or Shoutcast? If that is the case, how do I send over the stream from SAM Broadcaster directly to Flash Media Server without restreaming through another streaming server?
