Media Server :: Serving Live Streams To IPad And Android Using FMS?
Jun 13, 2011
I need to serve live video streams to Flash players, Apple devices, and Android and Blackberry handhelds. Right now I'm using FMS (actually, the CDN I stream through is running FMS), and configuring Wowza Media Server to suck the Flash stream from FMS and reprocess it for Apple, Android, and Blackberry. It works well, but it's kind oif a PITA having to have a separate server just to handle mobile devices.
Is anyone aware of any plans to release a version of FMS that will stream directly to Apple and Android? I saw a video clip on Techtilt of an Adobe presentation at NAB where they were showing live streaming to iPad, but that clip didn't way anything about when we might actually see that version of FMS become available.

I've been using FMS for a few weeks, and feel relatively comfortable with it, but am currently having some trouble connecting to a live stream in a a video conferencing-type application. I suspect I'm leaving some small step out, but am having trouble seeing what that step is.
I have one client application open the video camera, connect to the FMS, and publish it's live camera stream to the server. Something like this:
Connect to the FMS
nc.connect("rtmp://<ip addr>9/chat_test/");
In my connection (success) handler:
cam = Camera.getCamera();
cam.addEventListener(StatusEvent.STATUS, statusHandler);
...
[code]...
However, I keep getting "NetStream.Play.StreamNotFound" errors. This seems relatively straightforward, but I'm clearly missing a small step somewhere.

I am publishing 2 live streams from a computer with 2 video capture cards in it and I get a lag every 30 seconds or so on the subscribers side. I have tried adjusting the camera quality and setMode properties but still the lag persists inside and outside the LAN, is there a way to create a buffer on the server or adjust the way the live stream is received on the subscribers side so there is no noticeable lag? I saw something about editing application.xml to adjust the queue and a suggested bitrate but not sure if this is applicable, here is the link:
[URL]
Here is my setup:
The publishing computer:
2 PCI-e x1 cards, one takes S-Video (480i) and the other DVI (720p)
Windows 7 64bit
Intel i7
6 GB RAM'
GB NIC and Switch
From the switch is one hop to a GB router and out to a 10 MB pipe which leads to our datacenter 30 miles away. The swf on this side just gets the 2 cameras, sets the quality to (0,80) and mode to (640,480,25,false) (I have played with these settings a little) and creates 2 lives streams on the FMS.
The FMS:I am running Flash Media Interactive Server 3.5 on my own server with two 3.6 Dual Core Xeon processors and 4 GB RAM. This server resides in a Datacenter and has a 100 MB burstable pipe. From the FMS administration console I am barely using 4MB total bandwidth, 1% CPU usage, 2% RAM.
The subscribing computer:I have used many different types of hardwired PC's within the same LAN and outside the LAN, results are the same.The swf on this side just creates 2 new video instances and attaches the 2 netstreams to them. They are placed side by side and the height and width of these videos are undefined.

I own a site like ustream/justin where users can register and broadcast their channels using FMLE. Sometime I need to ban broadcasters after I receives any complaint against any channel. I do them on website, there is no issue in that. But how to do that on server side at FMIS. I need to do it bcause the stream users are already watching the channel page before it got banned, they still can watch it till they do the refresh. So I need something that can stop the Live Stream of that particular channel on FMS server too. How can I supply stream names to main.asc that should be banned or not to allow publishing without restarting server each time.

I am developing an application where I need musicians to play together and I want to have an audience listen to it. I have created my publisher clients and they can create the streams, but now I want to take those multiple streams and combine them so that you can hear the guitar, singer, etc. all together.

I wanted to know if there is any limit on the number of live streams that a client can connect to?For example, there are four live streams s1, s2, s3, s4 being published to FMS, can a flash client subscribe to all the four streams at the same time?If yes, what is the maximum number of streams that a client can subscribe to and what are the trade-offs?

I'm doing some tests with FMS and live streaming, but I observe quite long delays. When the stream is first accessed, the latency is around 3-5 seconds, which is acceptable. But as we watch the stream for about 30 minutes or more, the latency grows to around 20 seconds, which is just too much. What settings should I look at to keep the latency / delay minimal?

I am able to record live streams on server side. Now I am looking for an option to play recorded streams on server side when no one is publishing a live stream. Currently I am able to record all live streams that are currently being published in /opt/adobe/fms/webroot/live_recorded Folder. All the recorded streams are saved in stream.f4v format. I want to change main.asc in livemyapp folder in such a way that if any one is not publishing live streams of the name "abc" then automatically the client is served with the previously recorded abc.f4v in his browser.
Here is main.asc
/* * application.onAppStart:* is called when application load. It contains Live (out of the box) * application specific initializations. */
application.onAppStart = function(){ // Logging
trace("Starting Live Service...");
[Code] ....
What should I write in main.asc so that if a client is requesting to watch a stream and if that is not being published at the moment, he should be served the recorded version of that stream.

My Purpose is to record live streams on server side and play recorded files later. What I have done is -
1. Copied All files of applications/live in some safe location.
2. Copied all files from samples/applications/live to applications/live folder. (Deleted main.far from live folder)
3. Restricted SWF and HTML to mydomain in these files - allowedHTMLdomains.txt and allowedSWFdomains.txt
4. In main.asc I added these line in the end
var mystream;var intervalID;
[Code] .....
5. Then I restarted FMS and tried streaming using FLash Media Encoder. I was able to live stream and then i stopped it.
6. A FLV File was recorded in application/live folder with the stream name that i used in encoder.
I am able to view live video on my domain as well as some other domain, that means allowedHTMLdomains.txt and allowedSWFdomains.txt did not worked. Another issue is that I am not able to view recorded video after I stopped encoder but I was able see live video before stopping. I am using jwplayer to view the video and using flashvars streamer (rtmp://xx.xx.xx.xxx/live) and file(abc) to view the live and recorded video.

When broadcasting pre-recorded streams on a live applicationFMS always stops streaming at a certain time...
It can be after 10 seconds, it can be after 2 hours, or it can be after any other time, the frame just freezes on the client and the buffer drops to 0.
any attempt to diconnect / reconnect does not resume the streaming, althought the FMS console registers the connected client, no streaming is ensuing. One of the common events we get on the client in such instances when the streaming stops results in get "NetStream.Play.InsufficientBW".[code]...

I am facing a strange issue with a pair of FMIS servers set up with Multipoint Publishing. Configuration is as follows:
Encoder >>>> FMIS1 >>>> FMIS2
When freshly started, I am able to view live streams from both servers, however, periodically, FMIS2 unpublishes the streams as seen in the log below. When this happens lives streams are accessible from FMIS1 but not FMIS2. In order to resume live streams on FMIS2, FMIS1 must be restarted.

i have a website like ustream, where user can register and create live channels and publish live video using FMLE.
Now i want to check wether a particular channel is online or offline. I have stream name for particular channel. My website is coded in PHP. I have tried using getLiveStreamStats function, it works fine where the XML file is not heavy. I mean number of subscribers are less. Then i can just check the Publisher Tag. if it exists that means stream video is live, else not.
But problem arrives when the number of subscribers are high. The XML file do not loads in PHP, and it takes too much time to load the page.
what can be done to just check if the xml file has publisher tag. and display if the stream is live or not

When a client connects to an application (nc.connect) this is catched at server side using application.onConnect; so, when the client asks for a stream (ns.play) ... does this have some correspondence at server side ? Can we catch this event in some way?Or, seen from another point of view: is there any way, from within an application, to know what stream(s) the application is serving ? I mean, if we want the list of connected clients we have the application.clients array; is there any correspondence from streams ?

We have installed Flash Media Server on a Linux machine.It has 2GB of RAM,Fedora 9 with kernel 2.6.27.5-41.fc9.i686, the install required a few packages (compat-expat1 was one) to be installed before we saw the sample page. The sample page takes a few minutes to load and opening the page to connect to the admin console is about the same.
This is currently on our internal network while we try and see how it works. Are there any specifc TCP related kernel tuning parameters (eg in sysctl.conf) which need to be put in place over and above the out-of-box configuration. Any troubleshooting hints which might identify the problem. The install seemed ok nothing in /var/log/messages and checking to see what is running (ps aux | grep fms) I see
./fmsmaster -silent/opt/adobe/fms/Apache2.2/bin/httpd -f ./conf/httpd.conf -d /opt/adobe/fms/Apache2.2 -k start/opt/adobe/fms/fmsedge -edgeports :80,1935 -coreports localhost:19350 -conf /opt/adobe/fms/conf/Server.xml -adaptor _defaultRoot_ -name[code]....
but when we clear our browser cache and go to a page it is taking forever.It is taking about 5 minutes to open up the initial page, but when it is open the videos all seem to come through fine.The server previously had apache on it but I removed that copy and went with the version included with FMS.

We noticed that when we are streaming our own VOD file that we had copied to the server, which is an .MP4 file encoded at 1200 kbps using either HDS or RTMP (, which I suppose the server recodes on the fly ) we are getting the incoming stream at the average bitrate of 14 Mbit/s, and it looks like bursts of 25 Mbit every couple of seconds.
However if we try a sample file, such us sampl1_1500kbps.f4v we are getting an average of 1.2 Mbit/s with peaks of 1.5-2 Mbit. The tests are conducted in our company LAN. So what is the reason for this? And is there a way to control/restrict the output bandwidth for our own file without re-encoding? I'm not talking about several streams with different bitrate for the same source aka adaptive bitrate but rather about the single stream bw)

I want to record a stream which is published with Flash Live Encoder to FMS 3.5, but split the recording in files with predefined length. For example if a stream 'webcam' is published I want to record it in chunks of 10 minutes: 'webcam1.flv', 'webcam2.flv' ... From what I can tell there's no facility to work with timers. The only solution I could think of was using stream.record() with a time limit parameter but that seems like a hack because it triggerstStream.Record.DiskQuotaExceeded on the stream when the recordin should stop and start recording another chunk. Has anyone done something similar?

I'm using the server Stream.play() method to playback a recorded stream, it plays back fine until it hits the buffer limit (Say I set the buffer to 5 seconds, it will playback fine for 5 seconds). But then it freezes and playback is very stuttery (1 frame every 2/3 seconds). Is this a know issue? I'm using windows 2008 server. I've tried a few things to resolve this but no luck. The server is running the dev license and has no load.

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.
