[PD] simple video switcher

[Laurent Kappler]

Hi,

My goal is to make a simple video switcher.
It's what I have so far:

I'm very new to puredata, so I don't really understand the video flux I 
think.
The only idea I have is to use the pix_mix to switch 0 to 1 for the two 
entrance and do that again for each.
But it does not sound right at all.

Which object would be more appropriate for switching between video flux?

Thank you
Laurent
