Usb web cam library

[Alexander_Sobolev]

Can you advise library for acquisition from web cams?

Single payment or free, deployment should allow any number of applications. 

Configure, acquire (from multiple cameras in parallel), get image data (as imaq image, pixel pointer or array worst case).

IMAQdx is ok, but paying 440$ for every deployment PC for the simple task for the 20$ camera does not make sense.

Something like updated version of imaq for usb http://www.ni.com/example/30030/en/ 

Or good .net library that can be interfaced with labview will also work.

Now we are using aforge library (http://www.aforgenet.com/framework/), but it has limitations, also its last version is 2013, it is getting old.

Craig,

Thank you. Yes, I have seen them. All 3 solutions are based on videocap (Video for windows). Kind of works, but limited (can not set resolution above 640x480) and was obsolete in 2013 (https://stackoverflow.com/questions/2045125/webcam-capture-resolution-issues)

You could look at automating capture using more current tools like
