Capturing live video Tutorial

I found the article titled 'Capturing live video' quite useful. This article is linked off the FMS start web page - the one that opens immediately after installing.
http://help.adobe.com/en_US/FlashMediaServer/3.5_Deving/WS5b3ccc516d4fbf351e63e3d11a0773d5 6e-7ff0.html#ach-setscr
The tutorial is better than most that I've found because it has a simple, working example. I was able to enter the code into a frame script in Flash CS5 and I used my own FMS address to connect both to a localhost and a remote server. The sad part was that I found that I got the video and audio to round trip to and from the FMS when compiled (ctrl+enter) in the Flash CS5 program but when I try to publish this to a web page, I get audio but I can't get any video to display - neither eachoing straight from the camera or subscribing from the FMS. I've tried accessing the web page from my local file system and from a webserver. In both cases, I get audio (great news) but not video (bad news). I'm wondering why this might be. I checked warnings and errors but I'm not getting any. This solution is so simple and would pretty much solve my problems.
If anyone has made this example work from a web page and there was any trick to the matter, please let me know.

The problem was that I needed to go into the settings and switch the video camera. I had some mysterous google cam items that were not really cameras as far as I could tell. After that, it worked. Apologies for not notifiying the forum. I thought I had responded to this post to say it was completed but apparently not.

  • ISight Capturing Live Video

    hi all,
    I just got a macbook with a built in isight camera. The isight works fine for photobooth and iMovie. The problem i have is capturing live footage. I'm unable to have a video chat on ichat. Also, i tried using it on ustream.tv. It doesn't work. I changed the settings on the adobe flash player but it still didn't work. So, I think the problem is capturing live video.
    please help! It's frustrating me
    Thanks,
    Labze89

    Thanks for clearing that up, Labze89
    Based on that info, your iSight can certainly capture live video.
    Ustream identifies itself as a beta site, so you should expect to encounter some problems, but you should be able to resolve them.
    Good quality streaming video requires broadband speed. More info below on this subject. Contact your ISP if you need to purchase additional speed (bandwidth.)
    Streaming live video also involves proper settings for your modem (and router, if you have one). If you have not recently rebooted (shut down for about a minute and then restarted) your modem and router, do so now. Be sure to let the modem's self-test finish before starting the router. Let the router's self-test finish before restarting your Mac. Rebooting sometimes is all that is required. If restarting does not correct your problem, you will need to consider other possibilities.
    At least for users in the USA, enabling your router's "UP-n-P" setting is often all the router configuration that is required. However, sometimes manual port configuration is required. If so, the instructions for your router will give you the info on how to check and change the settings. What setting values you must use will come from the service (Ustream or iChat) you want to use.
    If you have enabled your Mac's System Preferences > Sharing > Firewall, enabling your router's "UP-n-P" setting may allow you to stream video without additional configuration of your Mac's Firewall. If the problem persist when your Mac's Firewall is set to "On" and your router's (if you use one) UP-n-P setting is enabled, you may need to configure the necessary ports on your router and in your Mac's Firewall. Search "Help" on your Mac or see this link for Mac OS X 10.4 Help: Setting advanced firewall options.
    Also, your ISP must not be blocking any ports required by the service you are attempting to use. See the ustream.tv FAQs for help on your ustream.tv problems. For your problem with streaming video, check FAQ #s 9, 7, and 15 first.
    To minimize possible conflicts, disconnect all unnecessary A/V peripherals (such as eyeTV, game consoles, iPods, etc.) and quit all other applications while troubleshooting your problem. You can try adding them back one at a time once you can make your streaming work reliably.
    If these and the other FAQs do not help you resolve your ustream.tv problems, and if you do not get help from some other Ustream user here, click ustream.tv's Contact Us link for email help directly from the people who determine how the site works. They should be your best source.
    <hr width="85%">
    If you use dial-up, or if your broadband speed is not fast enough, iChat AV will also have video problems.
    The Mac OS X 10.4: iChat AV system requirements show all requirements for using iChat AV. For instance, you will not be able to use iChat's video if you do not have at least 100 Kbps broadband both up and down. You can test your internet service's uplink and downlink speed (bandwidth) at Speedtest.net.
    If you need to post back for more iChat AV help, please confirm that your system meets all system requirements and list your uplink and downlink speeds in your response.

  • Capturing live video

    I am trying to capture soccer games live and while searching through this forum I found it was very easy to capture live video with a DV camcorder so hopefully my next question is possible as well.
    Am I able to upload (stream?) this video instantaneously so other people can view the video live?
    MacBook Pro 2.16 GHz Intel Core Duo, 1 GB DDR2 SDRAM Mac OS X (10.4.7)

    Daniel,
    Have you considered using conference recorder along with ichatav? I think it's freeware (not sure).
    Keep in mind iChat quality won't even come close to iMovie quality. That's a given.
    However, on my own G4 733 DA Mac system I am able to use both iMovie6 and ichatav3 at the same time (I have 3 ADS FW web cams on my system that i can switch back and forth from at will, as well as a sony 3 chip camera and a video capture card from canopus)
    In fact yesterday I used iMovie6 with an internal Canopus video pci card to capture a TV show to my HD, while also holding an ichatav three way video chat. And if that wasn't impressive enough all on it's own ; i was also able to launch QT Broadcaster and Safari on a third FW web cam.
    So yes, it is possible but I don't necessarily recommend doing this because it tends to overwork the cpu and at worst it can cause a kernel panic. However, mine worked smoothly & flawlessly .... although each additional app I opened slowed performance down significantly on most other open apps.
    Btw.... Don't try this at home because at worst, it could trigger a kernel panic.
    I'm fairly open to risk taking myself because I have mult. systems to work from. And I've only had a kernel panic twice in my life (both of them on my laptop).
    Lastly. this should tell you something about laptops in general. Don't expect to overwork them like you can a full size G4 or G5 tower. Most laptops simply aren't built for this.

  • Capturing live Video From DV Camera

    I Tried to capture a church service using iMovie. I Expected multiple files because of the file size limit and imovie braking up the file. I also assumed that these files butt seamlessly together, but to my surprise they do not. How can i get a hour+ of continues live video recorded?

    Please note that I don't believe your camera will put out a proper full-resolution, full-quality HD signal via HDMI while in record mode. DSLR cameras are notorius for not allowing you to fully turn off info overlays on the HDMI output, or even if you can on your particular camera, the output signal is somewhat cropped or otherwise not a proper HD signal.
    We're a reseller of the Atomos Ninja portable recorders and this has been a huge issue - DSLR shooters want to use Ninja for the exact purpose you mention, for long, uninterrupted recordings, but the HDMI outputs from those cameras are just not suitable.
    Do this - connect the HDMI out from your camera to an HD display and start recording with the camera. Do you get a perfect, full-screen image without any overlays or any cropping, and at full quality? My understanding is that they all "dumb-down" the output signal in some regard while recording, unlike video cameras that will all put out a perfect HD image. The only 2 DSLRs that I'm aware of with "clean" output are the Panasonic Lumix GH2, and the new Nikon D4.
    As mentioned, even if a DSLR camera will put out a good image, you will need a "capture device" with HDMI input such as BMD Intensity or Matrox MXO2 Mini connected to Mac or PC.

  • 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!

  • Capturing live from a video mixer

    We video our church services and want to make weekly DVDs of them. We have been using Final Cut Express with mixed success, but are about ready to switch to iMovie HD for several reasons.
    The question is, can we capture live video from the video mixer (mixing two cameras and one computer to a single signal) to our hard drive using iMovie HD? If so, how.
    Many thanks!
    Pastor Ron Heffield (macfiveo)

    First of all, if you're shooting either normal (4x3) DV or 'widescreen' DV, you'll have to select the appropriate format when you start a New Project. (..See items 6 and 7, and the accompanying pics, in my post here..)
    So when you slide the little onscreen selector from the "scissors" icon to the "camcorder" icon, and then click on the camcorder icon itself to choose the name of your mixer it may show "DV-VCR" or some other device name, as it's unlikely to know the exact name of your mixer. If no name is showing, and the iMovie screen says "No Camera Connected", just quit from iMovie and then restart iMovie.
    You should then see the live feed, and then just click on 'Import'.
    Alternatively, instead of importing with iMovie, you might try downloading and using BTV. You can then edit that captured material with iMovie.
    [..P.S: I don't think BTV, or BTV Pro, is a "universal" application, so it should work OK with your PowerPC Mac(s), but maybe not with an Intel-based Mac..]

  • Live video capture while playing back another video track?

    Is it possible to capture live video while another video track is being played back? I would like to do this for multitrack video recording of music: a) record a video track, then b) record a second video track while listening to/watching the first. Exactly like multitrack recording of audio as in Garage Band, but with video.
    A similar question was asked here, but I want to avoid manual synchronization. http://discussions.apple.com/thread.jspa?messageID=11712024&#11712024
    As an example, there are lots of multitrack videos on youtube, but you can often tell synchronization has been done manually as the audio and video are out of sync (even if only slightly):

    Many thanks!

    I'm not too familiar with video editing (yet), so please forgive me if I've misunderstood your suggestions. I think what I'm talking about would have to be done post (after shooting multiple video tracks?), and couldn't be done with video switching (live switching between multiple video feeds?). Here's a much better example of what I'm trying to do: http://www.youtube.com/watch?v=PGKErn2Zr88
    What it boils down to in my mind is precise synchronization of a new capture with something pre-recorded (be it audio or video). If no software can do this (yet), perhaps there's a way to do it with additional hardware, for example playing video on a monitor while simultaneously recording with a camera, assuming the devices can be synchronized somehow?
    Thanks!

  • How to display live video captured by a webcam on another computer?

    I am now writing a program to display live video captured by a webcam on another computer which is in the same network and I need to make it display on a applet page.
