Using OpenCV Output as a Webcam

So, I want to write a program so that the processed output from OpenCV is considered as a webcam. I want to use it to create effects for a program like Skype. I got stuck and googling didn't help. Please help me. Do I need to get a driver for this? How about saving as AVI and streaming AVI with some other application?

I want to write a program to mask my face, so I don’t need to worry about my privacy when talking with the people I teach, and I personally don’t know!

By the way, I'm a little new to C ++. However, this is the language that I prefer. However, I also understand Java and Python.

Are you suggesting I try to get another library / library collection, like OpenFrameworks?

I am programming OpenCV in C ++. Here are all available platforms for me: Ubuntu: OpenCV from apt-get, with pkg-config, QT Creator Ubuntu: OpenCV from apt-get, with pkg-config and libfreenect, QT Creator Windows 7: OpenCV 2.4.8.0, latest binaries , x86, Visual Studio 2010 express Windows 7: OpenCV not installed Windows 8.1 Pro: OpenCV 2.4.8.0, recent binaries, x86, Visual Studio Express 2013 Express Desktop, Hyper-V, same configuration as Windows 7: 1

I noticed a bit of confusion. I am trying to use processes derived from an open CV and send them to another program such as Skype. The main intention is that I am going to teach elementary school programming and OpenCV. I would like to stream directly, so I don’t need to share my desktop.

I have no experience marrying skype, but it seems to be possible. You just need to create the right conveyor , something like: gst-launch videotestsrc ! ffmpegcolorspace ! "video/x-raw-yuv,format=(fourcc)YUY2" ! v4l2sink device=/dev/video1 gst-launch videotestsrc ! ffmpegcolorspace ! "video/x-raw-yuv,format=(fourcc)YUY2" ! v4l2sink device=/dev/video1 gst-launch videotestsrc ! ffmpegcolorspace ! "video/x-raw-yuv,format=(fourcc)YUY2" ! v4l2sink device=/dev/video1.
