I'd be more than willing to test anything you can bring up, as I have
some v4l1-only apps that I cannot patch ... one such is Marratech:
www.marratech.com. There's a free client that you can download and test
with if you want, and I have a technical contact there that listens with
interest to these developments.

Another is Flash (yes, Macromedia Flash). You can test the camera using
e.g. www.flashmeeting.com (you can start a demo session without
registering, but if you need to set up longer tests, contact me). I
haven't managed to get a response from Macromedia on that point,
though :-)

Also, note that my patch did *nothing* to help me, so I'm not at all
sure I did *anything* right... it's based on pure imitation.

It's possible that using USB2 would help, as USB1.1 seems to force the
cam into MJPEG mode, which it seems few or none of the v4l1 apps
support. If I use USB2 I should get YUV from the cam even using the v4l1
compat layer, right? I'm probably getting a new laptop in a few weeks,
so that might help...
