Live Stream connection limit per server

I Need to Broadcast 20,000 to 40,000 Live Streams.! (Bitrate : 128Kbps / Viewers Per Stream Apprx-10 Server : Adobe FMS Server Amazon EC2 Instance - Bandwidth Apprx 100mbps)
My Question is
1. How Many Concurrent connections Possible for one Adobe FMS Server? (Amazon EC2 Instance)
2. is this possible to use RTMFP for this process? (20,000 Connections Via Amazon Adobe FMS Server EC2 Instance )
3. if Possible Over RTMFP then How Many Developer Keys Need for this Operation. (or) Pricing Details for the Developer Key. (or) Any Separate Key[s] Available For Amazon EC2 Instance?
Thanks
Sarma

1.  Looking at your stream specs - its like  128 X 10 ~ around 1 Mbps for one stream considering 10 clients. And considering bandwidth of 100 mbps for instance you can support around 1000 clients. But few things i want to know before we can conlude on figures - what is NIC capacity of the instance.
2. Yes if you using FMS on AWS offering - you can use RTMFP
3. You don't need developer keys if you are using FMS on AWS offering to use RTMFP

  • How to store Live stream on the other Server

    Hello Everyone,
    This is very important for me to store all live streams in the archive server at F4V sormat.
    to do that I record live stream in the F4V:
    mystreams.publish('mp4:' + netstream.name + 'f4v');
    mystream.recod();
    This cods is work currently in the rootinstall directory's but I wan to store on the archive directory in other linux server.
    1- I share the archive folder in the archive server.
    2- Create folder on the AMS linux server in the applications/livepkgr/streams/_definst_/archive
    3- mount archive folder to the archive folder in other server:
    mount -t cifs -o administrator=root,password=myams //192.168.1.100/Archive /opt/adobe/ams/applications/livepkgr/streams/_definst_/Archive
    So Archive Server is: 192.168.1.100/Archive.
    Now I have problem to store live streams in the Archive server...!!!
    When I start publish live events on the Flash Media Server, AMS is make video file with f4v format in the Archive server (ams have access to write in other server) But this file has 0kb. there is no capacity.
    Please advise me to solve this problem.
    Many Thanks.

  • How to secure Flash Media Streaming Server 3.5 (live stream connection)

    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?
    Any help would be great, 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 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?

    If you are concerned about anyone starting publishing to your stream then we have security update on this. Please upgrade to 3.5.4 and now you can use FMS Authentication Add-in (used with FMLE as publisher). If you are facing problems with publisher which are not FMLE, please enable SWF Verification so that only valid SWF's connect to your FMS.
    You can find 3.5.4 update here : http://www.adobe.com/support/flashmediaserver/downloads_updaters.html
    You can find FMS Authentication Add-in on FMLE Download page: https://www.adobe.com/cfusion/entitlement/index.cfm?e=fmle3 (when you click on Agree - it will prompt for your Adobe ID - then when you reach Download page - you will get Optional Download of Authentication Add-in)

  • Timecode/TimeStamp in RTMP live streaming using Adobe Media Server and FMLE

    HI There,
    Am trying to stream a video on to Adobe media server(using RTMP) through FMLE and play it on my web site using JWPlayer. i could stream the video successfully, but know i want to get the timestamp/timecode on the stream. does Adobe media server and FMLE support this kind of use-case ? if not is there any other way to achieve the same. any comments/suggestion/pointers appreciated .
    Thanks in Advance
    Regards
    Deepak

    If you're talking about nonstop, continuous streaming, your subscribing client will need to close and reconnect the stream every couple of days, as the server will run out of timestamps for the stream.

  • Max-streaming-connections-per-session limit

    Hello,
    i'm trying BlazeDS with Air app.
    I set blazeDs on a Jboss Server with JMS adapter.
    I configure it with a streamingAMF channel.
    In user agent configuration i put msie, firefox value to 10 for the max-streaming-connections-per-session limit param.
    In Air client configuration i instantiate a producer and a consumer on the same streaming AMF channel.
    After the consumer.subscribe() i launch the producer.connect() on the server i get this error :
    14:25:20,015 INFO [STDOUT] [BlazeDS] Endpoint with id 'my-streaming-amf' cannot grant streaming connection to FlexClient with id '497031A2-7B0D-019A-0E1D-7622A-A631D28' because max-streaming-connections-per-session limit of '1' has been reached.
    Is it a limitation of use of blazeDs with Air app ?

    First, if you change the limit to 10, then it should be 10 and not 1. If you still see 1, then please log a bug.
    Second, you really want this limit to be 1 in IE and 4 in Firefox 2. But there's no reason to have more than 1 streaming connection from the server to the client unless you need to talk to two different endpoints.

  • Max streaming connections per session error

    I have a flex application that uses messaging with a streaming AMF connection, falling back to polling. When the max number of streaming connections on the server is reached, it does fall back to polling (at least it prints the max-streaming-clients error but the client connects, so I assume it is falling back - how can I tell?). However, occasionally the streaming connection will not initialize and it does not fall back - no messages are received on the client. The following error is logged on the server:
    [EMST]09/25/2008 13:43:18.231 [ERROR] Endpoint with id 'my-streaming-amf' cannot grant streaming connection to FlexClient with id 'D5B8E3A1-1A1C-063E-84A6-6A743A1E4EE0' because max-streaming-connections-per-session limit of '1' has been reached.
    This would make sense if the issue was caused by trying to initialize the streaming connection in two tabs of a browser, but I am only trying to initialize in one tab. Closing the browser (and thus destroying the session) does not fix it. The only solution I've found is to reboot the client machine. This has happened in both FireFox 3.0.2 and IE 7.
    (1) What could cause the client to get in this state?
    (2) When it happens, why doesn't it fall back to polling? Is the fallback only for when the server max connections is reached? When the streaming connection doesn't initialize, no messages are received.
    (3) Is there a way to explicitly close the streaming connection on the client so we can fix this without rebooting?
    Thanks!

    Hi Mary. If you turn on Debug level logging on the client and the server you should be able to tell if you have fallen back to a polling channel after the attempt to connect over the streaming channel has been rejected. In the client log, you will see the flex application sending poll requests to the server at the polling interval configured in the channel and in the server log you should see that the server is receiving these requests.
    The behaviour you are seeing seems very strange to me. The reason we have the max-streaming-connections-per-session limit on the server is because most browsers limit the number of active connections that can be made to a server from a single session. In IE for example, this is 2. What happens in most cases when the browser's connection limit is reached is that new connections are put on hold until one of the existing connections closes. This would cause your flex application to hang with no errors being reported on the client or the server. This is why we need the max-streaming-connections-per-session setting on the server. This prevents more than one persistent connection from being made from the same session, so the browser should never reach it's max connections per server limit and lock up.
    It looks like you are somehow getting the browser to lock up even though the server is only limiting you to one streaming connection per session. It may be possible to do this if you reload the flex application in the browser (by doing a page refresh) in which case the browser could possibly briefly leave the streaming connection open in the background and when you tried to create a new streaming connection, the browser's connection limit to the server would have been reached and the application could hang. When the application hangs are you reloading the swf/page in the browser?
    I really don't know why closing the browser wouldn't fix the problem. You're right that closing the browser should end the session. If you launch a new browser and load the swf do you get the same "cannot grant streaming connection" error on the server or is the browser just locked up, ie. no error is received on the client and the server?
    You're not using a proxy server or anything like that are you that might be holding a connection open to the server?

  • Help understand Visual Communicator Live Streaming

    Up to know I run live streaming through our Steaming server using FMS and Flash Media Live Encoder as we only needed one camera for live video feeds.
    We are looking at the ability now to use 2 live cameras and also the ability to snap in pre recorded video during live feeds and also provide lower third titles.
    I am looking at:
    Adobe Visual Communicator 3
    Wirecast 4
    CutFour
    All of these provide the possible live switching I need.
    I'm at the moment looking at the Trial version of Visual communicator and I am struggling getting my head around a few things.
    I can hook up 2 -3 Sony A1 HD cameras in SD no problem and running it though FMS is fine. During test streams clicking on the cameras using the mini switcher is straight forward.
    howevr I am struggling to work out how to do the following:
    Add prerecorded video clips to Camera 3? ( in the Setup Tab it says " No Camera found - please connect a camera or replace with Photo or video Clip) How do I replace with a Video Clip?
    How do I add premade titles, so that during the live feed I can put lower third titles in?
    Finally, How do Provide an intro looping video to play before the live feed starts?
    Any instructions would be appreciated

    c) The compiled SWF file version of this Application's blueprint. (file: timer_module.swf).
    What i need to confirm is: ........................................................ see the next post of mine. (for Problems  need to be Resolved)

    Problems to Resolve:
    Problem#1) - Countdown Timer to the designated Date for Live-Broadcast-Event yet to take place.
    Problem#2) - Detect End of Live Stream on FLVPlayback with FLVPlayback.isLive = true;
    Problem#1 Description:
    I need to pinpoint the Logical TimeSync Exception, i am still unable to figure out. That is I'm using a webservice in my Application to Synchronize the Time with the actual ET (eastern time) with accomodation of auto-adjustment for EDT GMT-4 (eastern daylight time) & EST GMT-5 (eastern standard time), times. I am using the zipcode: "10012" to pass it to the Web Service in urlRequest object, to retrieve the Current ET eastern time according to EDT & EST time settings for Manhattan/Brooklyn areas or others within  New York, NY 10012.
    Currently the Web Service is returning accurate date/time based on local EDT GMT-4 daylight time.
    Is there some defined set of dates for EDT & EST times for New York region that I can check for to ensure the correct Dates/Times for Eastern Time in New York area ??? I am using NY zipcodes because i am sure to get correct ET values.
    The Major Problem Part: is I need to correct the time by 2 seconds or approx. 2 secs, some millisecs.
    When I retrieve the Time Value from WebService, it lags behind for 2 seconds as compared to DateObj i create using computer's local time, on my Windows XP Service Pack 2 with Automatic Updates turned-on. And I'm sure about my Windows will be having latest updates for Time Management already installed. I also added the 2 secs. to the TimeSync(ed) Date to make correction to this Date obj.
    I call my custom fucntion addSeconds(dateObj:Date, secs:int) to add 2 seconds to the Date by Converting Seconds to Milliseconds.
    Please comb through the as code in files attached and Help Me Out !!!

  • Live stream to start with keyframe

    Hi,
    In a .3gp file, it always start streaming at the first frame (zero seconds in to the stream), so the player always received an I frame first and displays the video correctly from then on.
    In a live stream on the Quicktime server it start streaming at current frame (eg. 13 seconds after the encoder has started), so the server sends 5 P frames to the client first then an I frame. The client would display a distorted image for 5 seconds until an I frame was received.
    Is there any setting on the QuickTime server to always send I frames (key frames) first for a live stream?
    QuickTime Streaming Server Software Version: 5.5.4   Mac OS X (10.0.x)  

    Big thanks for your reply
    Really helped me on my long understanding way to upgrade my live chat application to
    work with IOS devices.
    So lets continue... make this important post to be a good helper for all developers on their way to stream to IOS devices.
    If you can I clarify this - Nitin Goel says:
    "Remember, that you need to publish video as H264 codec and audio as AAC/HEAAC for it to work with ios player.. Flash player may not yet support this combination.."
    It is not possible for me to use Flash Media Live Encoder.
    In this article:
    http://sonnati.wordpress.com/2011/05/14/a-dream-comes-true-h-264-encoding-into-flash-playe r-11/
    it says:
    "A dream comes true: H.264 encoding into Flash Player 11"
    and its done by this actionscript 3 code:
    var h264Settings:H264VideoStreamSettings = new H264VideoStreamSettings();
    h264Settings.setProfileLevel(H264Profile.BASELINE, H264Level.LEVEL_2);
    stream.videoStreamSettings = h264Settings;
    which will be connected to the NetStream like this i guess:
    var h264Settings:H264VideoStreamSettings = new H264VideoStreamSettings();
    h264Settings.setProfileLevel(H264Profile.BASELINE, H264Level.LEVEL_2);
    nc = new NetConnection();
    nc.connect("rtmp://example.com/livepkgr");
    ns = new NetStream(nc);
    ns.videoStreamSettings = h264Settings;
    ns.publish("livestream?adbe-live-event=liveevent");
    Is this what need to be done in order to publish video as H264 from webcam and Flash Player 11 in user browser?
    And what about publish audio as AAC/HEAAC?
    Another important thing:
    I am writing my actionscript 3 code in my flash CS4 and publish it to swf.
    With this code obviously it give me error...
    do i need to upgrade to CS5 or CS5.5 and then i will be able to publish with this code?
    again big thanks for any help

  • Live Office Connection not showing Go to Object Option

    Hi All,
    i m using Xcelsius Enterprise 4.5. I have created a dashboard in which I m having a live office connection. I had added the live office connection from a Webi Report, Binded the Prompt and created a live office connection to the server. The report was working fine.
    After a couple of days when I open the report again I find the Go to Object has been disabled in the report and the Modify Object shows only Properties option. The Refresh Object also does not work.
    Could you tell me what has gone wrong and how to fix it.
    Thanks

    I am still on Xcelsius 2008 but faced similar refresh disabled problems. May be this helps:
    These days I maintain a Live Office Excel spreadsheet and import it into Xcelsius after any kind of changes.
    You can maintain the data connections part within Xcelsius as required, but treat Live Office Excel report as a separate unit and set up all the refresh properties at report part level before you import it into and start developing the Xcelsius.
    This way the refresh never gets affected and it works every time.

  • AIR SDK 16 (and 15): live stream video pauses when from non-iOS to iOS

    Using either sdk 15 or 16, when live streaming video through media server, if I go from iOS to iOS devices, no issue. If I go from non-iOS device to iOS device, the non-iOS device receives the video and audio fine from the iOS device, but on the iOS device the video it receives freezes (almost from the start, after a couple of frames, then long, long pause of freeze - minutes long - then a few more frames, then freezing, etc.) - the audio is fine, it appears to be just the video. I have tested this with android to android (fine), android to desktop (fine), iOS to iOS (fine), android to iOS (freezing video only on iOS side), iOS to desktop (freezing only on iOS side).

    VideoTexture is a HUGE improvement for video on Windows and iOS. I am testing on Windows 8 and iPhone 6, but VideoTexture is still in beta and will take a few more months to get the kinks worked out. It is working for me on iOS sometimes, and whenever it works the pixels have a transparency applied to them. I have logged that pixel transparency bug here:
    https://bugbase.adobe.com/index.cfm?event=bug&id=3936111
    Also you will notice that Adobe has mentioned the following in the known issues section:
    [Air Desktop] [Video Texture] Video is not playing if texture is used as ConcreteTexture of starling.(3949908)
         (Release Notes | Flash Player® 17 AIR® 17)
    On iOS the VideoTexture seems to work for MP4s loaded directly from the file system, but RTMP is not ready yet. But when it is ready, I suggest that you adopt it immediately since VideoTexture is where Adobe is focusing it's video efforts.

  • Network.http.max-persistent-connections-per-server keeps reverting to user set 4

    I didn't used to have this problem as far as I'm aware, but as of recently, I've noticed that if I try to download more than 4 of one thing at a time from the same site, it would fail. For instance, if I have up 5 web pages of streaming content, only 4 will load, the other 5th one will do nothing until I finish one of the others. Upon looking up some information on this, I saw that the network.http.max-persistent-connections-per-server is set at "user set = 4", and if I change that number to anything else, it corresponds. If I click to 'reset' the number, it goes to the default of 6 - which is still less than what it used to be. I used to not even have a limit on this as far as I'm aware, or if I did, it was well beyond 10 and that wasn't a product of me manipulating it.
    What I'm asking is this:
    1) How do I make this so it permanently switches to a higher number? Every time I reset it to 6 or I manually change the number to something higher, once I close it, those settings go back to 4.
    2) Why is it reverting and not staying the way I change it?
    3) What's the purpose of this and why is it just recently doing it when I haven't put any new add-ons or made any other refinements to Firefox that I'm aware of?
    Any help would be appreciated

    Two possible causes for it resetting to 4 that I can think of.
    # You have an add-on handing that pref and that is resetting it to 4 when Firefox is restarted.
    # That pref is set via user.js and that causes it to go to that value as Firefox starts.

  • Increasing max-streaming-connections-per-session has slow acknowledge response?

    Our application is a Flex GUI with a WebLogic Server (BlaseDS) on a private network.  We were originally using IE 6, but have upgraded to IE 8.
    I am trying to use publish/subscribe messaging to monitor lengthy processes on the server and received incremental data.  With 1 such process everything works fine.  But we want to allow the user to subscribe to more than 1 message destination.  So I increased the "max-streaming-connections-per-session" (default is 1) in the services-config.xml file
         <channel-definition id="process-notification-streaming-amf"
              class="mx.messaging.channels.StreamingAMFChannel">
              <endpoint url=https://{server.name}:{server.port}/{context.root}/messagebroker/streamingnotificationamf"
              class="flex.messaging.endpoints.StreamingAMFEndpoint"/>
              <properties>
                   <user-agent-settings>
                        <user-agent match-on="MSIE" kickstart-bytes="2048"
                             max-streaming-connections-per-session="3" />
                   </user-agent-settings>
              </properties>
         </channel-definition>
    If we leave max-streaming-connections-per-session as the default value of 1 and try to subscribe to another message destination we get an error indicating limit has been reached:
         [BlaseDS]Endpoint with id 'process-notification-streaming-amf' cannot grant streaming connection to FlexClient with id '7FFC82DE-etc ' because max-streaming-connections-per-session limit of '1' has been reached.
         We upgraded to IE8 as documentation indicates IE8 allows for an increase of max-streaming-connections-per-session, where IE 6 is limited to 1.  But increasing max-streaming-connections-per-session does not quite solve the problem.  We have 3 consumers; consumer1, consumer2, consumer3.  For each of these consumers, we add event listeners for MessageAckEvent.ACKNOWLEDGE and MessageEvent.MESSAGE.
         We call consumer1.subscribe().  When we receive the acknowledge message, we call consumer2.subscribe() (likewise with consumer3)
         The problem is it takes over 2 minutes to receive the acknowledge message from the call to consumer1.subscribe().  (With max-streaming-connections-per-session set to 1, the acknowledge message is received in a few seconds.)
         So, increasing max-streaming-connections-per-session removes the error about reaching a limit, but it appears to come with a cost of a big delay in a long delay on the call to subscribe?  Or is there something we are missing?

    I guess I will answer my own question.  Hopefully this will be useful to someone else in the future...
    The problem was coming from IE being limited to 1 connection by the registry.  The solution can be found at:
    http://support.microsoft.com/kb/282402
    I manually performed the steps to update the registry, though microsoft provides a "Fix It"; MicrosoftFixit50098.msi
    One other key element was to make sure to have kickstart-bytes="2048".

  • MacMinis + SL Server for Intranet live streaming ?

    Hi,
    is this asking for trouble (not enough horse power) or can the MacMini be used for a live stream into our intranet?
    The documentation on this Apple site actually suggests a Macbook (for the Broadcaster) and a MacPro (as streaming server).
    We will need to do this only, say, three times per year for 45 Minutes.
    Signal will come via Firewire 400 from the camera.
    Will two MacMinis be able to handle the load?
    How many clients, do you think, can connect at the same time before we run into trouble?
    Thanks for any friendly advice,
    Barbara

    There's a lot to consider when dealing with streaming.
    If you're only streaming to the LAN then you might be able to use multicast, in which case this is a no-brainer - the server only sends out a single video stream to which all the clients subscribe (the heavy work is done by your network switches).
    If, on the other hand, you can't use multicast, or if your 'intranet' really consists of multiple sites/locations then you need to consider bandwidth since that's likely to be your major bottleneck.
    It really doesn't take much CPU to stream a connection (the hard work is in the encoding which is why Apple recommend a separate machine for encoding which passes the stream to another machine for distribution). I don't know what the hard limits are on a Mac Mini as the streamer but I wouldn't be surprised to see at least 100 clients on a reasonably-high quality stream. If you find it can't handle that (or you have way more clients) then QuickTime Streaming makes it easy to add additional streaming servers so all you need to do is balance your clients across the various streaming servers, making it easy to grow incrementally once you work out what your load is.
