It might be some VDCAssistant programs using it.
Try this ,Open a terminal window and type the command below.
sudo killall VDCAssistant
This will kill all other programs and you will be able to use your camera again.
Start by selecting "New Video Recording" from the File menu.
Quicktime Player will open a preview window streaming your webcam video. Resize and position as desired.
Select "Float on Top" from the View menu.
Now start your screen recording.
Apple (or a 3rd party) should write a utility to allow you to dial down the native resolution of the internal camera, but to my knowledge they have not, so far.
You can work around this by piping the video output from your web camera into another program that processes the camera's video stream and "re-publishes" it to your Mac as a virtual camera (aka ...
"iSeeYou: Disabling the MacBook Webcam Indicator LED" is a paper by Matthew Brocker and Stephen Checkoway from the Johns Hopkins University. In this paper they explain on how to disable the LED when using the camera. In short: normally you use the CPU to access the camera and activate the LED, but you can also use the processing unit in on the camera board ...
Kinda roundabout, but you could try this:
Choose File -> New Movie Recording.
On the little down arrow to the right of the record button, choose maximum quality. Also drag the record button holder to least obtrusive location.
Command-3 to fit to screen.
Take screen shots with command-shift-(3 or 4).
If you just want to see what your webcam is showing:
Open QuickTime Player --> File --> New Movie Recording
It will give the option to record what your webcam is seeing but you don't have to. It will show a video feed from your webcam.
As an alternative to QuickTime Player you can use VLC. You'll have to download it from VLC's website.
Delicious Monster makes an awesome piece of software called Delicious Library that's intended to do exactly what you're after: scan and catalog your library (of books and other things). And it all works through your iMacs built-in iSight camera. And it works very, very well. From their website:
“Wait, I just hold a CD or DVD or video game or book or ...
My understanding is, it depends on the model of your Macbook. The ability to turn the camera on without the green light was only proven in pre-2008 laptops. No proof exists that you can do the same in post-2008 laptops.
This question Are there privacy concerns with the Built-In iSight Camera and LED Indicator? seems to agree that newer models you can't.
As commented by @aglasser to fix the Cam not working simply:
Open Terminal.app; and
Run: sudo killall VDCAssistant
In order to resolve another similar issue with the built-in Microphone:
Open Terminal.app; and
Run: sudo killall coreaudio
What about c-slide? (http://www.c-slide.com)
1 mm thin and works with all latops and pad devices.
The cool thing is that you can open and close it without having to remove any parts from you laptop. And it's sleek, the only downside is that it is black and might not look very nice on a white MacBook frame.
"ResEdit" was the basic utility to inspect/edit resources such as images, video, and sound in Mac OS applications and games. It runs in Mac OS or Classic environments and can be downloaded from http://www.mac.org/utilities/resedit/
"ResFork" runs on OS X 10.2 and provides similar functionality to ResEdit.
Using ResEdit or ResFork you should be able to find ...
Try the free Skitch (also available from the Mac App Store). One of the many things it can do is a Cam Snapshot. To take one, invoke Skitch, then choose Capture > Cam Snapshot. You may need to fiddle a bit with the size of the snapshot to get full resolution.
This worked to the max resolution of the iSight on my older MacBook Pro; it's worth a try on the ...
Delicious Library wasn’t made just for scanning a list and dumping it out, but it could be used for such a thing. After scanning in your items you’d either want to slurp the results using a custom AppleScript or you can use our export-to-CSV feature and only do the ISBN column.
If a book doesn’t look up on Amazon there’s an error window that pops up, and ...
Apple don't provide any way to control camera devices centrally, it is left up the program in use to provide the ability to choose.
Generally, well written programs give you a choice, and poorly written (and, generally, poorly supported) programs don't. (Photobooth, I'm looking at you.)
The only way I know to force a program to not use a camera is a hack ...
The simple answer is no - in general the one camera only sends data to one app.
The more complicated answer is that the API (application programming interface) that Apple publishes enforces this restriction. If a developer hooks into the hardware directly or there is a bug in the API, it is possible to share that stream.
So for most Apps made by someone ...
According to this Apple discussion forum post:
As you know, software always controls your iSight. Most apps,
including all Apple apps of which I am aware, automatically make the
iSight settings for you and do NOT allow you to manipulate them from
within the application.
In my own case, I have found that merely adding more light to my work
I just discovered QR Journal, which works fine for me. The latest version requires OS X 10.8/10.9 but there is a legacy version available which works with 10.6.
Now desktop users with an iSight (or iSight compatible) camera can read QR codes. Found a QR code in a magazine or catalog? Simply hold up to the iSight camera to scan, store and browse to. ...
To disable iSight and other cameras, use:
sudo kextunload /System/Library/Extensions/AppleCameraInterface.kext
(tested on 10.9)
I'm not aware of a way to disable audio input without affecting output. It's the same hardware so unloading/removing the kext probably won't work. One step you can take is to turn the input volume down to zero in your sound ...
It's possible you have installed, or someone else has installed, a system utility to capture the image from the iSight when opened. This is often something an anti-theft application might do, in order to track down the user of a stolen laptop.
One combination of utilities that can do this sort of thing is "sleepwatcher"
You might check to see if there is ...
Objective See has an application that continuously monitors webcam and microphone activity called OverSight. It throws up a notification if either become active and has worked well for me.
Note: the developers rightly warn that this software may not catch all malicious use of the webcam or microphone.
You can open a second instance of QuickTime using
$ open -n -a QuickTime\ Player
# │ └ Specifies the argument is an application to open rather than file.
# └ Open a new instance of the application even if one is already running.
Each instance can start a New Movie Recording with different inputs.
You can then use iMovie to combine the two ...
Try IP Cam by Senstic available on the Mac App Store (no affiliation with the developer).
This app claims to work over a private network without needing active connection to the Internet. From the app description:
Start IP Cam on your mac.
Take a note on the HTTP access address shown by IP Cam.
For Wi-Fi remote viewing, enter ...
According to the User Manual available here this actioncam cannot be used as a webcam. The prompt you get upon connecting the device via USB lets you probably choose between Mass Storage (UMS) Protocol and Camera (usually abbreviated PTP - Picture Transfer Protocol).
Both protocols let you transfer pictures from the actioncam to your Mac/PC but neither of ...
Today I stumbled across a proper publication regarding this topic: Researches from the Johns Hopkins University recently published the paper "iSeeYou: Disabling the MacBook Webcam Indicator LED", showing that they were able to deactivate the iSight status LED on older MacBooks even without root access by replacing its firmware.
It appears they were able to ...
