Live Video on Express
Is there a way to connect a camera to your mac to run live video without using firewire? Is it possible to use airport express and the USB connections? I want to be able to move away from my mac and firewire doesn't give the distance I need. I have a small program called Video Viewer for live video. It works well.
Any Thoughts?
Thanks
You can't use the USB port on the Airport Express.

A wireless camera would be an option, however virtually all rely on a PC for configuration and operation.

Hi,
I have created a program from where you can look at a live video (contious aquisition within a loop) and from that, create a template which you then use pattern match on. The idea is to be able to track movements of the template (in my case components on a PCB) in the live video. Everything works just fine, however, when I try to change the template in the program (I have a button in the GUI where you can either create a new template or load a previously saved template), the program for some reason still uses the "old" template. I'm not succeeding to change the template used in the pattern match part of the vision assistant express vi while I'm running the program.
If I stopp and restart the program I can load a new template however.
I'm beginning to think it has something with the image aqusition and not disposing images correctly, to do but I could need some help.
Is there an example out there that uses live video pattern match where you can load/create templates on the fly?
Thanks!Thanks Sasi,
I looked at the example but it not really what I looked for. In your example, the match is done on a previously recorded video file. What I would like to do is to do the matching on a live video.
I've managed to do matchpattern the first time I load or create a searchpattern. But if I want to change the match pattern template while running the VI, it continues to use the old one...(I'm aware I have trouble explaing the problem...)
The structure of my VI is as follows:
while (not stopped or stop aquisition of images)
1. Continously aquire images
2. Do a search pattern task (a -no pattern match, b -use "old" pattern, c - create new pattern and d -load a previously saved pattern)
3. Do a pattern match (use vision assistant to do a pattern match on the image aquired in step 1, with the template from step 2.
4. Overlay the match (if found) to the image aquired from step 1.
5. Calculate the radial movement between two following frames (the calibrated matches array from vision assistant in step 3.
6. Save radial movement to file
end
It works, but I have to restart the VI before I can use a new template (otherwise it just keeps showing the first match)
I guess it has something with how I aquire images, to do?
Best regards,

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. -
Can I connect an external video camera to a mac book pro for viewing live video so I don't have to use the little screen on the camera?

• 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
AshleyMaybe 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:

What are the requirements to build a live video chat application?
I am looking into making a live video chat application. I
have seen several examples on the web so my question is not "how"
to do it. My question is "what do I need" to do it?
It seems that all the examples use Flex Data Services and
then some sort of back-end communication server. The cost of FDS is
well beyond what the client can afford so my question is: is it
necessary? Is there a way to build this sort of application without
FDS? Can I get live video streaming to work using only what is in
the SDK? I know nothing about data streaming, real-time
communication, etc. and have no idea how to implement this outside
what I have seen in the online articles so far.
If there are any other forums that are more appropriate to
this question, please direct me there. It is not a FDS exclusive
issue and I am just starting to look into it. I am starting here

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.

I know that the built in iSight camera records video. I want to set up a Canon 5D video camera and feed the Canon's video output into the MacBook Pro so that I can use the vectorscope in Final Cut Pro to adjust the exposure of the Canon 5D. Basically I don't want to buy a vectorscope to have on set to make sure the picture is properly exposed and color balance is correct. (In your response it doesn't have to be the full scenario I've described. If you can just tell me if there's a way to feed live video into the MacBook and display it on the screen and possibly record it, then I'll figure out the rest.)
Dear Ben,
Thanks for your help. Apple and I dealt with this. It was an FCP, NOT Motion problem. As It seems you understand, we simply trashed my FCP prefs. Problem went right away.
Thanks. Do you live near Hammond? Played in a rugby tournment down there once. I was transformed.

How do you stream a live video to a website. I use GoDaddy to host a website. I can plug a video camera into my Mac so I can run the video through whatever program works best. I even have a .mac account (now its mobile me I guess) and could use that. I have read several threads but can't really find a starting point. Any help is appreciated.
