Is there any software that can capture the screen and turn it into a fake webcam input?

Question

Is there any software that can capture the screen and turn it into a webcam-type input so that you can easily record and/or broadcast your screen with regular video software?

Edit:

Just to be clear, I'd like to be able to use it live as an input to video conferencing software as well as for making recordings with video editing software. Bonus points if it allows me to capture a screen remote from the computer that is sending the video (for example by connecting to another computer with VNC).

So it should show up as an input alongside any webcams I have installed, but instead of being a camera, it should be whatever is on the screen.

Edit 2:

Skype's screen sharing feature is exacly what I want, but it only works with Skype. I'd like to be able to do it with anything that uses a webcam - Google Talk, UStream etc.

Answer 1

here's mine: https://github.com/rdp/screen-capture-recorder-to-video-windows-free it's free and open source

Answer 2

VH Screen capture was exactly what I wanted. It comes in a bundle with VH Media studio which lets you mix multiple Webcams, with Picture in picture and fade effects, which was great for what I was trying to do.

Answer 3

This appears to be another one:

Medialooks Screen Capture DirectShow Filter

Answer 4

Well. I know FFsplit has a webcam output and works really well. I've been using that for ages, it cannot be started over command line. It can also stream to the major streaming sites and output to video. It supports picture in picture with multiple layers of regions, monitors or windows themselves.

Answer 5

Unreal Media Server has an optional add on called Screen Capture DirectShow source filter (half way down the page)

I haven't tested it.

Answer 6

CamStudio is able to record all screen and audio activity on your computer and create industry-standard AVI video files and using its built-in SWF Producer can turn those AVIs into lean, mean, bandwidth-friendly Streaming Flash videos (SWFs)

CamStudio is free open source software.
