Video Chat Scripts

Screen sharing requires a driver to capture the screen and simulate a webcam. There are multiple webcam simulation drivers of this type, commercial and free software packages. We tested the VH Screen Capture Driver that can be downloaded for free (for personal use).

With the screen capture driver enabled you just have to select the new “webcam” in flash (right click the flash and select from settings in any flash video chat software).

Only the user that shares his screen needs to have this type of driver installed. Those running tutoring, consulation, support websites can purchase a commercial software package that includes this type of driver (i.e. Camtasia Recorder with the Live Output feature).

Most drivers allow defining a zone to capture and even rezising the output. Chat applications usually require a 320×240 webcam stream at 15fps so you should configure output to that if possible.

Another popular method for screen sharing (as seen on youtube), but less professional is pointing your webcam to the screen.

Here is our test with the VH Screen Capture driver:
