Try searching for -9405 in this forum and you are certain to find the answer. Some other process has grabbed access to your video stream (other apps, other patches, etc.), so you'll need to close down whatever is using your camera input.

Hello,

thx andrew but nothing is using the camera. there's only max launched.

if i try to use photo booth or other application, the camera (isight) works well.

also max reconize firewire dv camera when plugged in the computer.

It happens for me when I directly close and re-open a patch without tell "close" -> [jit.qt.grab].

So the only thing I found is to disconnect the cam & reconnect, and re-launching the patch.

my problem is isight doesn't work anymore only with cycling products (max4, max5 and hypno) but works well with quicktime, finalcut, photobooth.

i had to reinstall quicktime because another problem with jitter.

i just reinstalled max4 and max5, but nothing changes.

maybe i erased something by mistake.

in fact "usb class video" doesn't appear anymore in the device menu.

i tried on a clean install of os10.5.7 + max5.0.7 and it works.

really sorry for the noise. it seems a quicktime component was missing comparing the 2 systems...

I also have the same problem as fp did. It says:

camera works perfectly in quicktime and photobooth. I updated my perian recently, could that be a problem?

I also have the same problem as fp did. It says:

error opening device for grab

and yes, it works if I close grab and restart the patch. Still I don't like it...
