Any free C# libraries for video recording (of the screen) around?

I am looking for free C#(.net) libraries that allow me to record videos(plus sound) of the screen of my computer (basically, to do开发者_Go百科 what camtasia does).

Is there anything easy to use, around?

Thanks

I came across this solution to your problem, which uses Windows Media Encoder 9 to record the desktop. It's a bit dated, but I think you might find it interesting or helpful: http://www.c-sharpcorner.com/UploadFile/satisharveti/EnhancedDesktopRecorder07222008041309AM/EnhancedDesktopRecorder.aspx
