Sounds like a driver problem. I recall putting in some sort of reset message and along with sending new dimensions it would pretty much work like instantiating pix_video again. But the nature of Quicktime might not allow for an app to recover a device that drops out without either restarting the app or the computer.

Hi List,
I use in my installation a USB 2.0 camera. Most of the time everything works as it should however occasionnaly the camera input disappears and I see a white texture instead. I replug the camera and restart and it works fine however if I try to fix it with the patch running I get when I try to send the pix_video the message device 6: could not make new SG channel error -9405
I send teh message enumerate and I see could not get SG channels device list
Any idea if this depends on the camera I use or if there is any way to make pix_video "see" the usb camera again after replugging it?
Thanks,
Florian
