[vtkusers] Capturing Video with VTk

[Mark Roberts]

Hello,

I have an ultrasound machine that I am going to be capturing screenshots 
from using vtk. Right now I have it plugged into a Sony DV Media 
Converter with an S-Video cable. Ideally, I would like to set up a 
window that I can stream the ultrasound video into and then capture 
screen frames. My question is, I am not sure how to begin this project 
and wondered if there was anyone who had any ideas?

Should I get a Matrox graphics card and use vtkMILVideoSource? Should I 
try to use vtkWin32VideoSource and how do I use it? Any and all help is 
greatly appreciated.

Cheers.
