Yes, but it can be very tricky -- I don't think many people use it. For
example, I can't get the default version to work at all on my SAA7134 chip. I
found this is because the DirectFB V4L videoprovider uses V4L2_MEMORY_OVERLAY
to capture from the card (rather than MMAP or USERPTR), which just doesn't
seem to work. I couldn't even find any references to OVERLAY anywhere,
perhaps the author looked at kernel sources. Could be this works fine on
other cards.
I got around it by forcing MMAP mode all the time. Try dfbsee -z /dev/video0,
which does the same thing.

Different problem.. I have no idea. What card do you have anyway? A USB
camera?
