Can I broadcast live video for 1000 users?

Hi:
Is possible, using Flash Media Server, broadcast live video
for 1000 users?,
how much bandwidth do I need?,
What system requeriment is need for this load (in linux)?,
What maximum video size and fps is possible to get?
regards,
Christian

You should have no problem serving a stream to 1000 users on
a single server (a dual xeon/2bg ram box ought to do it).
Your bandwidth requirements will depend on the bitrate of the
video stream. Multiply the stream bitrate by the number of users
(plus 1 for the publisher), and you'll get your bandwidth figure.
For example, if the video is published at 300kbps, you'll use
about 290mbps for your 1000 users.
For the video size, I wouldn't go much larger than 640x480.
The flashplayer doesn't use the video card to render video, and
redrawing the screen with a large video chews through lots of
processor cycles very quickly.

    i have made a few test with Flash Lite 3.0 and Flash Media Server 3  and I have to say that it is pretty easy to stream FLV Video files and  Live Video from local web camera to mobile phone. Here are a quick  instructions how to do it in Windows (I will publish Linux version  later).
    Play FLV-video from Flash Media Server 3:
    Install Flash Media Server 3 (download developer version)
    There are a few sample FLV files in applications/vod/media folder, so you can use one of them for testing
    Create a new Flash Lite 3.0 file in Flash
    Add a new Video symbol to library
    Drag this Video symbol to Stage and give instance name to it: video
    Type following programming to timeline:
    // make a new video-object
    var video:Video;
    // make a new NetConnection-object
    var nc:NetConnection = new NetConnection();
    // check connection status from server
    nc.onStatus = function(info:Object):Void {
      status_txt.text=info.code;
      if (info.code == "NetConnection.Connect.Success") {
        startStreaming();
    // start streaming video to phone
    function startStreaming() {
      ns = new NetStream(nc);
      ns.setBufferTime(5);
      video.attachVideo(ns);
      // play sample.flv from server
      ns.play("sample",0);
    // show info to user
    status_txt.text = "Connecting server...";
    // connect FMS 3 video on demand service (default port 1935)
    nc.connect("rtmp://your.server.ip.here:1935/vod");
    Go to Publish Settings...
    Set Local playback security: Access network only
    Publish your SWF-file
    Send your SWF-file to your phone
    Test and you should see FLV-video playing in your phone
    Play live video from Flash Media Server 3:
    Install Flash Media Server 3 (download developer version)
    Install Flash Media Encoder 2 (Windows only)
    Start Flash Media Encoder 2
    You should see your live camera in Input screen
    Press Start-button to start sending live video to Flash Media Server 3
    Create a new Flash Lite 3.0 file in Flash
    Add Video symbol and programming as you did earlier
    Modify your programming:
    // in startStreaming()-function
    // Flash Media Encoder 2 publish stream name is "livestream"
    ns.play("livestream",-1,-1,true);
    // start connection to Flash Media Server 3
    // Flash Media Encoder 2 publishes Flash Media Server's default
    // live publishing point, so connect it
    nc.connect("rtmp://your.server.ip.here:1935/live");
    Publish, test and enjoy

  • How can I change the password for the USER in SAP.

    How can I change the password for the USER in SAP?
    also I want to change the Language and  date Format b/c it's displaying in German language..

    Hi,
    Assuming that User has already his/her user-id and password, and now he/ she wants to change it.
    select the client and provide Log-in credentials. Now, instead of 'ENTER' there is one Tab: 'New Password' (up, left hand). Click it.
    Now, system will ask for new password to change.
    If you are asking from Basis point of view, then T.code: SU01 - User Maintenance.
    Enter User's id and Click Change icon.
    It will lead to Page: Maintain User.
    Here, Select tab: Logon Data
    There is a Sub-Tab: Password.
    Here, key-in change password and SAVE.
    For Language and Date format, contact your Basis-Personnel.

  • Can't change home directory for standard users (admin is OK)

    I'm can't relocate home directories for standard users.  Relocating works fine for admin users.
    When a standard user logs in, they get a message (paraphased) saying "the home directory is not available.  If it is located on a server, the server might not be online".  If I change the standard user to admin, this message goes away, and everything is fine.
    I created a standard user
    moved the home directory using the terminal as root: mv UserName  /otherlocation/UserName
    I then went into users and groups, other options and changed the home directory location.
    Rebooted, then tried to log in as the standard users.
    Next try - Deleted the standard user and created the same user with admin rights.  Followed the above steps and everything works fine.
    I don't want this user to have admin rights on my system.  Any ideas

    Hi,
    the AFP is has always been switched on. As for the path I believe this to be correct. The path I am using is:
    afp://musicserver/Users
    I'm not at the server right now so I mat have got the afp and : and / in the wrong order here but they are correct on the server.
    This however does not seem to put the a folder in the Users folder. Could it be something to do with my external hard drive? I am using a Mac Mini as our server (not ideal but fine for us, or at least was) this is booted from our external hard drive. This is the main system drive which is where the Users data is also stored. I have tried all possible paths I can thing of from replacing the 'musicserver' with the IP address. I have also tried adding the name of the drive to the path (System) but all does not work.
    Are you able to suggest anything I have missed? Perhaps I'm doing the path wrong?
    Thanks again
    Chris

  • Can't exec /bin/sh for single user

    Hi,
    When I boot up my iMac G5 it sits on the gray screen with the apple and spinning "doing something" icon, and then goes to a terminal window telling me:
    "can't exec /bin/sh for single user: Input/output error"
    It started doing this last night after multiple beachball of death situations. Anyone have any ideas? Or is it time for this old machine to be put out to pasture?
    Thanks

    Hi Mungo,
    invalid key length is a serious issue that can sometimes be fixed by "heavy duty" utilites like DiskWarrior and Drive Genius.
    If you don't have enough room to re-install the OS, though, you have seriously overfilled it and they may not be able to deal with the problem either.
    You should always aim to keep at least 15% free space on the drive, preferably more. On my 250 Gig internal drive, for example, I see the beginning of stability and speed problems when I get down to below around 30 gigs of free space. It varies a bit depending on what you use your Mac for, but my own preference is to always aim for 50 Gigs free on this 250 Gig drive.
    You have to fix the "keys out of order" problem before you even think of re-installing the OS.
    The best solution is to reformat the drive. It is unlikely that it actually needs replacing. However I still think you should buy another drive, but an external one, if you don't have one already.
    My approach to your problem would be:
    1) Go and buy a nice big external firewire drive if you don't have one already (ideally at least twice the size of your internal).
    2) Install OSX on the external drive (You may want to partition it into two volumes first, keeping one partition to store a "cloned backup" of your internal and one for general usage, overflow storage, etc)
    3) Boot from the external HD and copy across your precious stuff from the internal drive to the external. (If you have created two partitions on the external you could use the excellent utility "SuperDuper" to "clone" the internal to the second partition - the one witout the OS installed on it)
    4) Reformat the internal drive, preferably using the single "zeroing" option.
    5) Re-install the OS and software on your internal drive
    6) Copy back your data (documents, music, movies etc) to your internal but make sure you leave plenty of free space on it. If you have a large music library , or lots of movies, for example, you might want to keep them on the external, rather than putting them back)
    7) From now on use one partition of your external drive for regular "cloned" backups of the internal and the other for general storage overflow etc.
    Cheers

  • Init: can't exec /bin/sh for single user.....

    Has anyone come across this gem during start-up? it's outputting
    init: can't exec /bin/sh for single user: No such file or directory
    init: can't exec /bin/sh for single user: No such file or directory
    init: can't exec /bin/sh for etc/rc: No such file or directory
    This shows up after the apple logo on start-up. Any ideas?

    That message suggests that Mac OS X isn't able to open a shell or run the startup scripts because one of the items it needs is missing. Fixing this issue will require reinstalling Mac OS X.

    Hello,
    First you have to create a new folder or 2/3, om My Mac... Mail>Mailbox>New Mailbox...> Loacation>On My Mac.
    Highlight the eMails  & drag to the new box(es), if IMAP Mail will try downlodaing them again.
    If POP & Remove fron Server when downloaded it won't.
    Quit Mail after the move, log into gMail Webmail via a browser & delete what you wish.

  • How can I capture live video and still image by a DirectX compatible USB webcam using LabView ?

    Dear forum members
       I'd like to design a user interface which shows a live video and capture still images for it by a DirectX compatible USB webcam using LabView or NI Vision Toolkit, how can I do this ? and If this is possible How can I reach the webcam DirectX filter properties and set them using LabView ? I would be grateful to anyone Who lead me to the correct solution.
        Sincerely
        Cem DEMiRKIR

    Cem,
        With our example programs you can acquire and save an image (IMAQ >> File Input and Output >> Snap and Save to File.vi) from one camera, if you double the VI's to create the image and the image task, you can easily have one program acquire and save for two cameras.
        I may need more information on what you mean by calibration.  Do you mean basic camera setup?  That can be done in Measurement and Automation Explorer by setting up the options within the IMAQ settings for each camera.  Or do you mean more complex calibration for special types of images?  The more description of what you mean, the better I will be able to help you get it done.  You mentioned zoom and motion parameters, what kind of motion?  Our vision drivers only control triggering the camera to acquire, then analyzing, processing and displaying the resulting image.
        If you have more details on exactly what you want to do, that would be great.  Let me know if you have more questions, thanks!

  • Adobe Flash Reversed to Broadcast Live Video without a Webcam

    This is all true and is happening now.
    I had heard that someone had taken Adobe Flash to new limits, albeit surreptitiously, was able to remotely activate your webcam without indicator lights revealing the clandestine activity. I unashamedly hold an objection to the commercial use of personal and private information to gain revenue via direct marketing or by on selling said information and an even greater objection to government agencies collecting and using personal and private information to build dossiers on the very same citizens that governments are elected to protect and serve for the purpose of political influence, persuasion, terror or torture. The only thing worse than either of these two scenarios is tendered government contracts for the collection of personal and private data or buying directly from a commercial entity that have collected data on individuals.
    When I heard that remote activation of a webcam was possible, I took measures to counter this threat by personally managing the Flash settings in the web browser, ensuring the browser settings always matched the Adobe Flash settings for use in Google Chrome, either by selecting "ask before allowing website to access camera" or outright "deny access to camera" and deleting the "exceptions" for that particular website or all sites. To be absolutely certain of my privacy I added the auld low tech safety net which I was certain could not fail, a strip of gaffer or "duck" tape over the lens of the webcam. Occasionally I would also turn the inbuilt mic off for added piece of mind. I thought myself that perhaps I was being a little paranoid until recently when I began to suspect that I was being observed when I would enter a chat room. A look of surprise or a generous smile from the host would greet me upon my arrival, priding myself in the most basic of social etiquettes, good manners, I would always respond with a nod or returning the gesture in kind. However, this is where I became confused because the hosts were always reluctant to confirm this was happening when asked directly, or made an effort not to acknowledge my presence again, which in my eyes, is an admission of guilt.
    When I put my laptop to sleep by closing the lid evening last, the unusual and rare combination of hardware and software failure occurred activating the log on screen on the external monitor. Secure in the knowledge that the lid of the laptop was closed, a piece of black gaffer tape adhered to the webcam, I knew I would not get a better opportunity to prove my suspicion that Adobe Flash has been re-coded to not only play live video but to capture and broadcast it as well. I entered the chat room and sure enough an acknowledgement from the host was immediately forthcoming. A moment of divine intervention allowed a conversation to evolve where upon I revealed that my webcam had been disabled and my monitor was acting as the only capture device. Having now confirmed my suspicion that my monitor, not the webcam was broadcasting video, I set about collecting additional evidence and to make the case rock solid,  enlisted an independent witness at my end to find on this verdict beyond reasonable doubt.
    My unsupported theory is that, if this technology has indeed been developed legitimately, it has been done so for the purpose of Windows 8, because although this computer is running Win7 Pro it originally came with Windows 8 but as I had ordered the computer with Windows 7 Pro, I sent it back to HP and they returned it with Windows 7 installed.  I have been informed by my I.T guy that Windows 8 has new hardware configurations that are specifically designed for the Win 8 platform.

  • Can't import live video from Sony PD 170.

    Just got Final Cut Pro X. In a New Event I am able to import live video from the new MacBook Pro computer's built-in camera and pre-recorded video from my Sony PD-170 camera. However, when trying to import live video from the PD-170, the program only APPEARS to do so--the clips never show up once I close the import window. Any suggestions?

(Maybe because I didn't delete the receipts?) iMovie can not see any devices or use iSight for capture...

    This is an AVCHD camera. On import the AVCHD is converted to AIC. So bottom line is, no streaming from this camera.
