[PD] [pix_video]: no valid video backend found

[Steffen Juul Christensen]

Dear pd-list,

I can instantiate [pix_video], but not find and use the build in webcam of my computer.

I’m running Pd Pd 0.45.4 32bit with
GEM: ver: 0.93.3 
GEM: compiled: Nov 10 2011
on a Macbook Air running OS X 10.9.1

The [dialog( message does not open a dialog window.

Sending [enumerate( makes Gem print the following to the console:

"videoctl: enumerate
could not get SG channnel Device List
[pix_video]: no devices found”.

When [pix_video] is instantiated it claims that 

"[pix_video]: backend #0='Darwin'	: darwin dv iidc analog “, 

but none the less I’m told that

"[pix_video]: no valid video backend found”.

A Open CV library for Processing 2 ensures me that the camera does work.

Using Pd-extended (shipped with Gem) doesn’t help me.

Any help/clues are appreciated. I’m sorry if this is trivial or a faq. I’ve search the archives with no luck.

Best,
Steffen
