Re: [PATCH] libv4l: add hflip quirk for dealextreme cam sku #44507

[Hans de Goede <hdegoede@redhat.com>]

Hi,


Thanks for the patch.

I'm sorry, but a quick google shows that your cam has a usb id used by various generic
cameras, including some microscopes, see:
http://blog.littleimpact.de/index.php/2011/10/16/using-biolux-nv-on-ubuntu-linux/

Enabling flipping on all these models because one has the sensor mounted upside down
is the wrong thing to do.

Instead you could add the following to your /etc/profile
export LIBV4LCONTROL_FLAGS=3

Note this will flip the image from all cameras you plug into your computer, or you
can keep a patched libv4l around for yourself.

Regards,

Hans
