Capturing Video From a USB camera - Please Help
I am a postgraduate student using max msp for my studies. I'm quite new to max msp and jitter.
I am running max msp on a macbook pro and am trying to capture video from an exernal, usb camera instead of the built in iSight camera. The first problem I encountered was getting a windows based USB camera to work on my mac.
For this I found macam at http://webcam-osx.sourceforge.net/ - I downloaded the driver and installed it as instructed. Opening the macam application switches on the USB camera and it functions fine.
When I try to capture the camera in a jitter window however, it does not. Instead 'Internal Error' comes up in the window. I am using 'getvdevlist' and the name of the webcam comes up in the drop down box.
Can anyone help? The web cam i am using is a Logitech Quickcam STX.
Hi Jonathan,
Unfortunately, I can't help you cause I have exactly the same problem. Although the (cheap&crap) webcamera works ok with macmac and imovie, it doesn't with Jitter. To make it even worse, when i press 'menu' in 'hi' object, the web cam doesn't appear in the usb list.. Any help around?
thanks,
Mike
? Why would the USB Camera appear as a HID device?
did you try getdevlist and getinput list in jit.qt.grab?

Hi,
yes i did.
With 'getdevlist' I get 6 devices. The last one is "Mustek WCam300A (C)". every time i load this device a get a warning (well, 4 basically) in Max window saying " An audio device has been added or removed to the system..." which probably means that it is trying to recognise the webcam.
With "get input" i get only "Mustek WCam300A (C)" which probably means that's the correct device..
thanks for your interest,
M
similar problem here.. using mac cam, macbookpro, 10.4.1... using jit.qt.grab I an unable to locate USB camera. does anyone have any solutions besides purchasing an expensive firewire web cam? (i need 3)

macally icecam works fine on macbook pro, osx. video quality isn't the best.
Encore Electronics USB Express Webcam works fine with jitter and macbook pro. It's cheap.
I HOPE YOU SOLVED YOUR PROBLEM. I HAVE JUST BOUGHT A LOGITECH USB WEBCAM QUICKCAM VERS 10.1. i HAVE INSTALLED THE DRIVERS HOWEVER WHEN i TRY TO OPEN IT IN JITTER IT IS GIVING ME AN ERROR SAYING THAT THERE IS AN ERROR OPENING COMPONENT DEVICE. THE PATCH IS A NORMAL JIT.QT.GRAB. CAN ANYONE HELP ME WITH THIS. OH AND BY THE WAY THE OPERATING SYSTEM IS WINDOWS XP.
THANX
Try jit.dx.grab, and please turn off your caps lock.

Hi,
I had the same problem trying to use a crappy usb-cam with Max/jitter. After long hours with sincere effort - i gave up and bought Unibrain iFireWire cam's. Works perfectly. as close to 'plug-and-play' as you'll ever get.

after "installing" the macam componoents, i can recognize my mother's usb webcam, which is a logitech quickcam express. works fine here.
