It probably is possible with CALL_EXTERNAL. I doubt SOCKET would work
unless your frame grabber is attached to the network and it serves up
data via TCP/IP. You'd have to check your frame grabber docs.

Why don't you post what you have tried with CALL_EXTERNAL. You should
be able to glean relevant information from your MATLAB
loadlibray/calllib functions to get you started in IDL.
