Well, the EyeToy cam uses the ov519 chip, which is different from the
ov518. For the ov518 I think, you also load a "decompress" module,
which then handles the converting from the compressed data to <what?>.
Or this is done in the driver module itself. Not so for the ov519.

Also I think, it's not jpeg compresseion with the ov518, otherwise the
decompression could just be used the same for the ov519 as well, which
I guess, the module author would have done then.

No, I don't see a real picture at all, just about 10 scanlines of
noise in the top of the pdp or gem window. It might be, that this is
the header of the jpeg frame taken as image in <what?> format.
