Media Server :: Live Multicast On FSM Remains Active After Client Disconnects
Mar 9, 2011
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?
when doing a live encode with Flash Media Live Encoder 3 to FMS 3.5, the encoder disconnects randomly after 1 to 8 minutes.It takes about 50 seconds for the encoder to recognize the lost connection, then it re-connects. I tried to encode from different locations, but the problem remains.
i have a small LAN of about 8 computers all of which are running windows 7. I have installed FMS and XAMPP webserver on one of the machines. I want to stream live from one PC to all the other PCs on the LAN. I have a webpage with jwplayer embedded in it on my XAMPP webserver that is able to see the live stream when i start it locally. I mean the live stream works fine on the machine with the servers on it. But when i want to view the live stream from another machine in the LAN by accessing the webpage that has the jwpalyer from another machine, The jwplayer returns "server not found:rtmp://192.168.10.1/live" error. I was thinking that maybe a firewall is blocking the 1935 port but i have turned off the firewall of every PC on the LAN. I have unistalled any antivirus program on all the PCs. But i still get the same error when i try to access the live stream from another PC on the LAN.When i run netstat -a -n|find ":1935" i get 192.168.10.2:49184 192.168.10.1:1935 SYN_SENT and i think the request for the stream is sent but the conection is rejected.
This is the code for the webpage with jwplayer embedded in it. maybe it: <html>head> <title>JW FLV Media Player</title> <script type="text/JavaScript" src="swfobject.js"></script>
No I have installed fms4.5, but I can't find good docs how to set something like this up. In Learning section I saw a lesson, but this one isn't ready.So I want to publish using flash and the subscribers to the livestream can be iPhones or Browsers.
Is it possible to stop a (live) Stream from playing for a user, but keep his NetConnection open for eg chat functionality?I only see a setBandwidthLimit to accomplish something similar to this, but then, if BW is set to 0, chat won't work.Why isn't there a built in feature to do something of seemingly common necessity like Client.stream.stop/change function to stop or change what video playback the client sees?
insert captions into a live flash video stream.[URL]this example uses a Flash client app wich can invoke something like video_nc.call("sendDataEvent",null,inputfield_txt.text);How can do this without any Flash client/environment ? (I of course still use an FMS 3.5) I would like to use a python (or php...whatever) piece of code to extract caption from VBI in the incoming video stream and insert it in the flash stream.
I am publishing video content to FMS with my program to livepkgr application. After i start publishing the vidoe content, files like .bootstrap, .conrol, .f4f and .meta are gettign created inside the livepkgr folder's my stream folder. But when i try to playback via OSMF player, the player is throwing error 1009. This happens for some few minutes. After some 4-5 minutes, the player start playing the live video content properly (.f4f file size is not getting updated for those few 4-5 minutes)
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?
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.
We have a video broadcasting platform and we use FMS 4.5 to broadcast a multicast stream. My question is : can we do QoS tagging of this multicast stream ?
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?
We have a problem with amazon FMS 4.0.3 server for enable muticast.In the server we have open all the port for ensure the good works.but when we used the http://public-dns/multicast/multicastplayer/multicastplayer.html, we have this message : The connection attempt to FMS failed.In the server administration we can view the Flash Media Live Encoder session but the multicastplayer cannot connect on the rtmfp://public-dns/multicas
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?
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?
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.
how can I find on fms server that client disconnected if if client disconnected due to power cut off. I client manually close the application then onDisconnect on server is called but if due to power cut off it does not called.
I would like to know if there is a solution available that allows me to plug 2 HDV cameras into a laptop and live switch between the 2 cameras while uploading the live stream via adobe flash media live encoder to the adobe streaming server? the scenario is I want to offer live streaming of corporate seminars that I normally shoot with 2 cameras.
I have Flash Media Streaming Server 3.5 (not Interactive) running on RHEL5.5 x86_64 Linux.All is working well, however how do I prevent unauthorized access to connecting to the live stream and streaming content?How can I setup the server to require a user and password to stream live media to the server?I am new to this product and I have been reading some documentation but I have not found a clear cut answer on how to force a username and password to connect to the server to stream live content only.I am using the Adobe FMS Apache install, what files need changing?[code]I want to lock down a person from connecting to the server on the public internet and starting a live stream?Can this be done with a user name and password?
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"?
I'm running Flash Media Streaming Server and have only been serving VOD up until now. I had my network administrator open up port 1935 to the outside world during the setup process and now I can't remember if that was actually required for streaming VOD to clients. Most documentation I've read says that this port should be open, but I seem to recall reading something at one point that suggested it wasn't necessary.
I've just started messing around with publishing live streams using Flash Media Live Encoder to the Flash Media Streaming Server. I have that working without issue but was surprised to find that no authentication is required before a client running the live encoder can publish a stream to the Flash Media Streaming Server. An authentication module is available however it only works with Flash Media Interactive Server and Flash Media Development Server.
If I leave port 1935 open to the outside world, there would be nothing to stop anybody anywhere from streaming video via my server. Anyone else running a default install of Flash Media Streaming Server and with port 1935 open to the outside should see that this is true of their setup as well. I'm wondering if I can safely close port 1935 without limiting the functionality of the server or if there's some way I can require authentication prior to publishing a live stream even though I'm not on the four-and-a-half-times-more-expensive edition of the product.
