Capturing Video From a USB camera - Please Help


    Mar 04 2007 | 9:34 am
    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

      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

      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.
