multiple jit.qt.grab objects with one webcam


    Mar 23 2006 | 7:47 pm
    Is it possible to use multiple jit.qt.grab objects with one webcam?
    I have an old Philips ToUCam running fine with the IOXperts driver.
    Trying to instantiate more than 1 jit.qt.grab with the same device at
    the same time doesn't work.
    My question:
    Is this simply impossible or could it be dependent on the camera and/
    or driver?
    Thanks,
    Roby

      Impossible. Just use one and send to two different locations (more
      efficient than it would be to grab the data twice from the camera and
      effectively the same result). You can store in a named matrix for
      driving at a different framerate/resolution if you like.
      Would recommend you use Jitter mailing list/forum for such topics, btw.

      Joshua,
      Thanks for the clarification.

      Sorry, didn't pay attention, but after using the max(msp) lists for
      more than 10 years I'm still not used to all these max/msp/jitter/
      java/dev/javascript/etc mailing list bifurcations. But that's
      probably due to my age.
      I'll do my best,
      Roby
