Hello,
It's probably the same problem, related to recent macs's built in webcam driver incompatibility with the video library used by Gem, that has been discussed last month on this list, and for which i proposed a workaround : make use of "iGlasses" shareware as a "webcam passthrough" (see "GEM Motion Capture" thread for details), but a real solution will require a rewrite of Mac OS X video-related code in Gem.

Regards,
Nicolas

I am starting to work with Pd and I want to do something with video editing. But I still cannot find a way for Pd to recognise my camera, when I try to work with a video patch, it just shows a white image. 

Can you please help me solve this problem? 

I have a Mac OS X Version 10.9.5
My version of Pd is: Pd 0.43.4-extended
And I'm working with the Mac's built in camera.
