M-kay.. so it's a digital processor. You can separate the fields quite
easily by copying every second line. This of course involves as many
memcpy()s as there are lines in a field.
Or process them in the buffer, no copying involved.
You can tell the driver to give you odd or even field only, I think.
But then you would only get the other cam, and you want them both,
right? It's a stereocamera?
