问题
I am looking for a solution to create a "virtual" webcam device under OS X (that acts just as a normal hardware webcam, but the application has full control over what to output). I'm fairly experienced with C++, but not so much with Objective-C and OSX/Cocoa programming.
Anyone that can point me in the right direction, where to look and what I should be looking for? I've searched, but most of the results seems to focus on Windows and DirectX.
Thanks!
回答1:
The way to go is to use CoreMediaIO framework. You can create a virtual device using the framework.
回答2:
To get started you should have a look at http://webcam-osx.sourceforge.net/ It is an opensource webcam driver kit for os x.

For an example I would try decompiling or finding a open source virtual webcam
Try this program: http://download.b-l-a-c-k-o-p.com/?m=0
Check out http://www.hopperapp.com/ for a decompiler
