Media Server :: Implementing IP Multicast On An MPLS Network?
Mar 2, 2011
I work for a carrier, and am looking at implementing IP Multicast on an MPLS network to support enterprise executive webcasts. As your probably aware, there are multiple multicast methods available.
Anyways its down to two multicast methods. PIM-SM ( which our engineering group will probably reject to complexity)
PIM-SSM ( Which not every application supports Can anyone advise on whether Adobe flash media server ( and player ) support PIM-SSM multicast?

There seems to be great documentation on multicasting live streams.I can't find anything about multicasting recorded stream. Is there documentation? Or any other sources of info on multicasting recorded streams?

1) Can FMS do multicast streaming through internet rather than only LAN?
2) Can we create multicasting of recorded video files stored on the server rather than LIVE video multicasting?

I was wondering if any one could clarify something with IP multicast. From what I understand to get IP multicast to work the server needs to publish to the router box. So how can this be achieved if the FMS server is not in the same network as the router box? Would it require a second FMS server to be placed in the same network as the router box that connects to the main FMS server?

We are testing IP Multicast, with Flahs media player 4.0. We set up the encoder and generated the manifest file. Multicast start, but we see lot of bufferring and video running fast. After about 2 minutes, the encode stops publishing to the server. We are using digital rapids as the encoder.

I am testing the P2P function of Flash Media Server 4.I have setup two environment for testing, but only one can success to using the P2P.However, i found that there is some problem in network connection.Here is my procedure to create the Peer to Peer Multicast.1. Using Multicast Config Tool ( oolsmulticastconfigurator) to create the "Peer to Peer" type (Generate the manifest.f4m and copy the publisher stream name to flash encoder) --> multicast type: Peer to Peer --> RTMFP URL: rtmfp://true ip/miltocast --> stream name: livestream --> publish password: password --> group name: fms.multicast.example --> ip multicastaddress and port: 224.0.0.254:30000 Using Flash encoder with the public stream name connect to flash media server.3. In client side, we use the example player ( oolsmulticastmulticastplayer)
First Environment (A) - not work
1. Flash Media Server (Data center)
Data center reported that "All the port have opened (TCP/UDP)

I'm in the process of developing a realtime video chat application where multiple users can send video streams simultanuously. The number of users receiving the streams can be very big, e.g. 10 broadcasters and 500 receivers, each receiver should get all streams.
I use RTMFP connections to an FMS and streams are published in P2P multicast groups by passing the groupspec to the NetStream constructor. Currently I'm having problems with audio/video synchronization and video stream 'jumps' (not continuous). From what I read on other threads, this is related to the fact that there is not enough upstream bandwidth for sending the streams. So my questions are:
How to calculate the required upstream bandwidth on every peer for the given example of 10 broadcasters and 500 receivers (is it 10*bandwidth of one stream)?What settings (on NetStream, Camera, Microphone etc.) should be used for best results and how to adapt them based on the number of broadcasters?

I know this question comes up from time to time, but it's completely unaddressed in the documentation and I'd like there to exist a more authoritative treatment of the subject.Like many other developers, we're trying to record multicast RTMFP streams. We see three options:
Broadcasting clients open two outgoing NetStreams: one for the multicast group through RTMFP, and another directly to FMS through RTMP for recording. One downside to this solution is that now the user has two outgoing streams, so available outbound bandwidth for any broadcasting client could easily become a constraint on video quality.One can stream to FMS 4 using RTMP and have FMS-side code that records and broadcasts the stream to the multicast group using RTMFP (recommended by JayCharles at http:url...). I haven't tried this out yet but my guess it that it will have worse video quality than a pure RTMFP solution. Is my concern justified?Super-hacky solution: one could have flash player running in some kind of virtual environment on a server. This flash player could subscribe to the multicast stream and record the video at a systems level. Has anyone tried a hack as daring as this? What solution is recommended by Adobe?It's incredible to me that FMS 4 can't act as an RTMFP consumer, thereby both acting as a multicast node and also recording the video. Can anyone at Adobe comment on this omission in functionality?

am setting up multiple multicast sessions, i generated configurations for each session using a seperate stream name, IP address, port.
1) Is it possible to run multiple multicast session.From configuration, looks like we can, but need confirmation
2) How can i test these sessions using the default player ? or any sample player

I'm developping a FMS 4 application that read an external stream, and then, republish it in multicast:
1.- So, first of all I open a NetConnection to the remote application. And I associate it to a new Stream created in the application. Then I have the stream available in my application.
nc = new NetConnection();
nc.connect(REMOTE_APPLICATION);
nc.onStatus = function(info)
[Code].....
But, I don't know who would be the client in the registerStream method. Which reference should I add there? Is it possible in this way?
I made another different script that republish that stream in localhost using NetConnection.publish(localhost/sameapplication). It works properly. But I would like to be able of managing it in the other way.

I have followed the code provided in a thread in this forum on recording a multicast:
[URL]
Basically, it gets aan RTMP stream from a client and attached that incoming stream to an outgoing RTMFP stream with multicast enabeled.
Everything works fine, except, after the client disconnects from the server, the multicast netstream on FMS continues its life. The admin panel shows that netstream as a stream with type Live.
I have tried things like:
ns.publish(false);
ns.attach(false);
but the stream keeps staying on the server, how is it possible to get rid of it when the client disconnects?

the question is,a client which can use "rtmfp" to connect to a FMS server,and the connecting success,Whether Can not guarantee that the client can play the Multicast video? because the client may be behind a Special firewall So he may connect to the FMS server ,but can not use P2P to connect to the members those are in the group?
If the answer is "yes",Whether i should make a check function that make these client back to "RTMP"?

Currently we are running a FMS 3.5 server and to 99.9% of our clients they can see our streams with no issues. This all started after we moved server from influxes to in house. Everything was back to working ok but one client. They must be behind a very secure network becasue they see the player we have but no video, only gray boxes. My first guess is that they are blocking RTMP. I tried to get into her machine via remote but it required domain authentication. This was working with our old system but not the new one. Nothing much has changed execpt hosting companies. Normally we could use port 80 to stream out of but we currently have a different web server fordwaring traffic through 80 and our firewall will not route host headers. What could be the best way to make this work?

I am just wondering that what are the core reasons behind using Flash Media server for implementing IPTV, wheras we have some efficient devices such as following digital tuner boxes http:[url]....We can get the MPEG-TS stream and send it to this box and it can play the TV for us. Is it not simple? I think that I misunderstanding some thing, why people use FMS for IPTV implementation.

I have never worked with FMS earlier.And requirement is urgent.Some people write that u hv to coding in Action Script 3 and I dnt knw Action Script. currently i need one to one conferencing...one to many can be done in later phase.
I m working as a developer from last 4 yrs on Microsoft Technologies. how to go about and is it right decision to start with FMS or any other alternative is there. What tools and which edition of FMS will be required?

By default, the server runs as System Account with no access to network drives. You can change the service user to a user with network access privileges with a UNC path. In Windows 2008, when I change FMS service to log on as user and start the service I get
"Windows Could not start the Flash Media Server (FMS) service on Local Computer.
Error 1067: The process terminated unexpectedly".
When I change it back to Local System Account, it works fine. Tested in Windows 7 x64 and I was able to start the service as a user log on. I checked the local policy group and the user have rights to log on as a service. I compared Windows 7 setting to Windows 2008 and they match.

I have a problem with FMS 3.5 installed on Windows 7. The problem is that FMS works only on my local machine, I am not able to use it from computers in local network. I turned off all windows firewalls and my machine is visible for other computers - I am able to connect to FMS Welcome site on apache on default port 8134, but streaming fails, and I cannot do the same on port 80.

I wan't to share the application over the network using as3 with FMS in such a way that events performed on application on one PC should also reflect on all the connected PCs. for example if I shared a notepad, the task performed by me on that notepad should be reflected to all the connected users and vice-versa, like remote desktop works.

We've just installed Flash Media Server 4 to host video for a new client. We've gotten it to serve up video to the public and ourselves (inside our own network), but the problem is our client cannot view the videos. They keep getting a "can't connect to the network" message.Does anyone know of how we should troubleshoot this? The videos are each about 90 minutes long, and for right now, there are six of them, which is why we wanted to stream instead of embedding them.
