Are these interlaced cameras?
Yes.
There's a known problem with b/w interlaced cameras, that probably also
applies to color cams (not tested). The effect is that the two field are
stored in the wrong order.
After playing around with the images a bit I figured that out :-)
I havn't found a reliable way to fix this yet :-(
As a workaround, you can force a certain field order by playing with two
configuration bits (VIA_GRABCTRL_GFLDPOL and VIA_GRABCTRL_GREGUDT_SHIFT) in
via_grab_setup() in file via.c. This should help.
Surely better than my current workaround, which is to pipe the images
through a little home-brewn program that swaps the fields.
Please report any problems.
