LAN: Live-Video 640x480 possbile??

hi there,
i'm trying to deliver a live captured videosignal from webcam
in 640x480 to clients on LAN. But I didn't come over a bandwidth
use of ~100kb/s (kbyte per s) so the quality isn't very good at all
(not smooth, latency). I just tested various configurations but I
didn't get it work using more bandwidth...
anybody knows what I do wrong? I've absolutly no idea :(
here's my last config I tried:
camera = Camera.get ();
camera.setMode (640, 480, 15, false);
camera.setQuality (1000000, 80);
tested on powerfull cpus..
thx and greetings!
marco

Ummm, the same way you broadcast a video file.
You feed the DataSource associated with your web cam through a Processor, program the Processor's tracks to output the encoding you want, and then you send that out via RTP.
And on the receiving end, nothing changes from the video file.

  • Live Video Broadcasting over LAN

    Hi Guys,
    I have studied the JMF Framework.
    And sucessfully transmitted and received video and audio over a network i.e. LAN.
    Also I have successful in displaying Webcam onto applet.
    Only issue with me is how do I broadcast the Live Video to clients.
    Do help me at the earliest.
    Thanks and Regards,

  • Jerkyness observed when live video encoded on FMLE

    Hi All,
    I am trying to encode live stream using FMLE 3.2 on mac mini.
    Input is of 1.5mbps with 640x480. It is coming throgh canopus and firewire to mac mini.
    I have set my bitrates to
    1. 800kbps H264 main @3.1 resolution 640x480
    2. 500kbps H264 main @3.1 resolution 480x360
    3. 300kbps H264 main @3.1 resolution 320x240
    My FMS parameters are,  FMS URL:rtmp://localhost/live  , streamname : livestream%i
    The live video encodes fine when i have only 1 stream encoding. But jerkyness observed when i have 3 bitrates enabled on encoder. What could be the issue?
    I thought i can use FMLE to adaptive streaming.
    I will be using 3 different streams for pc and mobile. Please let me know if i have any issues on the encoder side
    Any pointers would be useful.
    Thanks.

  • Live-Video and ACNS: Different documentation?

    I had found two statements regarding live- video and ETV:
    First in
    http://www.cisco.com/en/US/partner/prod/collateral/video/ps9339/ps7063/data_sheet_c78-504500.html
    "... Cisco ACNS provides both live unicast and multicast streaming services and on-demand access in which digital media files are cached locally for retrieval and viewed over the WAN at LAN speeds (Figure 3)."
    And the second statement in
    "Cisco Digital Media System 5.1 Design
    Guide for Enterprise Medianet":
    "... For Digital Signage and Enterprise TV live content, multicast is required as the transport. Cisco ACNS
    does not support unicast to multicast conversion for the delivery method used by Digital Signage and
    Enterprise TV. For this reason, Cisco ACNS does not provide any benefit for live content...."
    Is there an difference or is this an failure?

    I think the first statement should read:"ACNS does support unicast and multicast splitting for live broadcasts TO THE DESKTOP and with Windows Media streaming"
    The second statements hints to HighDefinition streaming which is mostly compressed with H.264 MPEG4, and i don't think ACNS is able to split this (or convert unicast -> multicast)

  • 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.

  • Live video distribution using CDN

    I am planning a ACNS/CDN deployment that will based around web-caching, prepos content, VOD's and Live Video distribution for town hall meetings to Corporate sites.
    I have completed the ACNS training and have a good picture of what I am going to be doing. The only real concern I have surrounds the distribution of VOD's and the Live streaming to potentially thousands of clients at each corporate site.
    My plan was to allow content acquistion (for VOD's and Live Broadcasts) across the WAN using Unicast streams to each of the WAE edge devices (Easy stuff). For the distribution to the LAN (which could be 500+ users) I figured I would enable Multicasting (IGMP snooping, not so easy?) I have never worked with Multicast but have assosciates who have, should i expect performance hits to the LAN? or is this the recommended form of distribution?
    I have purchased the proper licenses to accomplish this but before I move forward with this strategy I thought I would check here to see if anyone has done a deployment like this, I would love to hear some feedback both postive and negative.
    The CDN will consist of two tiers, with the top level sites having WAE-7326's and WAE-612's at the second tier. All sites have an average of 10Mbs links with ISR enabled routers and a collapsed backbone design in the core.
    Thanks!

    You can't override the physical camera and substitute the macbook camera.
    You could find an app or write one that would have the macbook stream the video over wifi from the macbook to the iPad.

  • Frames Missing When publish live video to fms server

    I am creating flex mobile application , that allows people to connect using a android camera and microphone,then recording video from android camera to Flash Media Server(FMS) 5 starter using adobe flex but when I play the recorded live video from FMS it's missing some frames. I have set the camera.fps to 30 but when I trace out the currentFPS for camera  30 and  netStream's currentFPS  returns low value, usually falls between 2 and 5 (high 1280X720),15 and 20(medium 640x480),25 and 30(low 320X240).where netStream is the object of the flash.net.NetStream class

  • Mid 2011 mbp i7 with a SSD has problems, including grey screen/blue screen/beeping/freezing when I stream live video (i.e. watch espn or time warner cable) Help? Ideas?

    Recently my Macbook Pro (June 2011, i7, 8gb RAM, 512gb SSD, AMD Radeon 6750, Mountain Lion - since July - currently 10.8.2) has been presenting me with an array of problems, usually initiated when I am streaming live video. I was streaming Time Warner Cable on 12/9 and it gave me what looked like the blue screen of death.  It started up after about five attempts that time. The other day, after about a week of not using the computer, it wouldn't boot past the grey screen. I (option) started it and it gave me two boot choices, the regular HD and a "10.8 restore" option.  The HD gave me the grey screen and the restore option gave me the dark blue screen. I reset PRAM and that didn't work.  After a force (x) start it worked.  Today, I was using "Watch ESPN" and the screen froze and the computer did some kind of repeating RAM beep or something.  I rebooted and it started up fine.  I'm not watching any videos anymore, but this is a problem since the primary purpose for my mbp is video editing. I'm still under AppleCare but I find more solid answers in the forums or at least better questions for the AppleCare people.
    Anybody have similar experiences, or a solid idea of what the heck has happened to my machine?

    I'm not really sure what method that person was talking about. I just read he had a successful install so I posted it.
    But I'll hazard a guess
    1. copy your entire drive to a backup drive
    2. boot into that drive and test it out - make sure its a flawless backup, it works, and the hard drive has no problems
    3. eject that drive, disconnect it and reboot into the leopard install dvd
    4. erase your main hard drive using disc utilities on the leopard install dvd -- you've made a backup, made sure that backup was good, and disconnected it so it's currently safely disconnected from the leopard install you're about to do. Also, on the hard drive you're erasing and installing leopard on to, many people recommend "Zeroing" it as well as erasing it. That option is part of the erase function in disc utilities on the leopard install disc.
    5. do a clean install of leopard
    6. follow step 4 from that original post exactly as that person described to do.
    7. read the rest of what they said
    That's pretty much it. With the backup/erase/clean install/import/ you pretty much get everything you need exactly the way you want it with very few things missing -- and you've done this over a clean install. Plus that poster did mention that you can select what you want to import from your backup hard drive.
    It sounds like its a "clean install" method that gives you control via "import from machine" option in the installer. Control over what parts of your "old mac" you want to import into your "new leopard mac".
    Hopefully that helps. It sounds more involved, but its actually pretty quick and provides you with a perfectly save backup in case anything goes wrong with the leopard install.

    • Only if your video camera supports it.  Depending on how your camera works, you may need to add preview software to your Mac to use this feature.
    • Alternatively, your camera may also be able to record directly into your Mac while you are monitoring the Mac's display.
    • If you are using a consumer camcorder that supports HDMI monitoring, a small HDTV might be an simpler solution than your Mac.  For an example of how this is done, see http://youtu.be/GVpSkZD6qE4.
    • The retailer who sold you your video camera may have other suggestions.
    • If you need more professional results, an external preview monitor will offer more capability on compatible cameras.

  • Is there a way to use Illustrator to draw over a live video feed coming from my microscope?

    Hi, we use illustrator to draw (trace) over static images of mite specimens taken under a microscope. Although this works, it would be much better to be able to draw directly from the live video feed coming from my microscope. The specimens are dead, so they are not moving around, however, we need to focus down through the specimen in order to see all details. We normally take montage images, but because the specimens are clear there are many artifacts present and we frequently have to consult the specimen under the microscope to double check things. My students and I have hundreds of drawings to complete and are looking for a way to streamline the process. If we could avoid making montage images and draw direct from the video feed, it would revolutionize the way we approach our research. Is there a way to display the video feed and then overlay Illustrator so that we can directly trace over the image (we use a Wacom tablet, but that shouldn't make a difference) so we can focus at different levels and draw the entire organism?
    Thanks for your help
    Ashley 

    Maybe it's possible to have live video in Illustrator, but you would most certainly need to write your own plugin.
    So this community would be suitable:
