Hi

I am getting this error and I am not sure why.

any ideas

• error: jit.qt.grab: could not create video channel -9405
• error: jit.qt.grab: error opening device for grab.

and then I get another error saying that another device is already open! I made sure that it is closed....

Please help!

Hi there!

Trying to resuscitate an old patch so I am using Max 5 again. I get the same error as the one from above.
Any suggestions? jit.qt.grab still works on MacOS Sierra?

Should work in my opinion. What kind of the camera are you using? USB or build-in into laptop?

jit.qt.grab still works even with Max8 and Mojave.

Hey Yaniki! Macbook Air built-in camera. Maybe there's a problem with my mac. I might have to reinstall the system

Hmmm. Try to open your camera in QuickTime Player, then in Max (with QT player open) - I just remembered that it worked for me once.

if I remember correctly, FaceTime cameras on recent macs are not supported by the 32bit quicktime drivers used by jit.grab in Max 5. I believe Max 6 at least is needed for that.
