800 MB for 320x420 frames? It sounds like your app has gooned its

That's an understatement. :-)

This might be due to endianess differences between MIPS abd x86 and
your app only being written and tested on x86.
</wild speculation>
My speculation too. I don't know where that number comes from; the
same app works fine with the saa7115 driver if I switch frame
grabbers. I'll have to do some fiddling with the code to figure out
where the problem lies. It's some interaction between the app and the
cx231xx driver.
HAH!
This simple patch fixes it on my MIPS platform - not tested on other
architectures as I don't have them readily available running a newer kernel:

No more errors and the frame grabber works up to 480x320 even on a slow
MIPS board.
