Please copy all the red error text - don't just snip out some of it. I'm not seeing line number, the actual line of code, etc.

Note: if the error message had instead been the slightly different

Unable to allocate memory for an incoming image frame due to insufficient free physical memory.

and you are using OS-X or MacOS, then see https://www.mathworks.com/support/bugreports/1422542

Ayesha,

On all platforms, use this before running any functionality from the Image Acquisition Toolbox to not limit memory for MATLAB:

imaqreset
imaqmex('feature','-limitPhysicalMemoryUsage',false);
% create videoinput objects

Hi, I have the same problem (using Matlab R2014a , macvideo and OS X Yosemite). When I write imaqmex('feature','-limitPhysicalMemoryUsage',false); I have the following error: Error using imaqmex The IMAQMEX feature specified is invalid. Would you know why?
