No Image capture in Mathematica 8 for Linux users

November 20th, 2010 | Categories: Linux, math software, mathematica | Tags:

I thought I’d try out the new image capturing functionality in Mathematica 8 on my Linux based laptop with built in webcam but…

In[1]:= ImageCapture[]
During evaluation of In[1]:= ImageCapture::notsupported: Image acquisition is not supported on Unix. >>
Out[1]= ImageCapture[]

That makes me a sad panda!

    Linux users have always been 2nd class citizens to WRI.

    +1 for South Park reference!

    You have Mathematica 8 already? or still?

    @sander already. I am a site license administrator for mathematica and so will be rolling it out to our site soon. Diary at

    Does ImageCapture work on Mac?

    Do you have any info and knowledge about how their new license manager stuff works (specifically on OSX, though I assume it is cross-platform)?

    They seem to have completely changed this from v7, but I can find no details on the web.

    Vladimir: yes, ImageCapture works on Mac. CUDA didn’t work, but worked after I downloaded and installed CUDA developer driver. It looks pretty neat, you can get morphological operations on your webcam feed rendering in real time inside Dynamic

    Can anyone please help me with CUDA? I have GTX460, which clearly has CUDA cores. Downloaded the latest developer driver, restarted, CUDAQ[] says False, and CUDAInformation[] returns “Failed to find CUDA paclet.” I’m on Win7 64-bit. How do I fix this? Any and all help would be tremendously appreciated!

    nevermind… :-) silly me didn’t have the Internet. LAN connection and about 1hr later, the paclet was loaded and voila! CUDA WORKS! Turns out that CUDAQ[] will not alert on error, it will just silently report False for “no CUDA for you, you disconnected simpleton”.
