[Pkg-spca5xx-devel] Bug#468445: gspca-source: Cam delivers a very narrow field of view in flash applets

Package: gspca-source
Version: 01.00.20-1
Severity: normal

I have a 'Logitech QuickCam Communicate STX' and use the gspca module to
operate it. The cam works fine in applications like Camorama, amsn and
Ekiga. I have noticed though, that if I use the cam with a flash-based
application on a website (using flashplugin-nonfree) the cam does work,
but shows a much narrower field of view. I have made two screenshots to
illustrate the problem:

  http://www.jan.vornberger.net/sonstiges/gspca/screenshot.flash.png

The first screenshot shows Camorama, the second one shows a flash applet
from this website:

These messages appear in the output of dmesg when I use the cam:

I'm not sure if this is really a bug or rather a 'feature' of flash. I
could not find any cam related settings in the flash plugin settings
menu. I would consider it a bug/problem, because the very narrow field
of view makes the cam pretty much useless. But feel free to reduce the
severity of this bug report or inform me why this is not a bug.

On a related note: I wanted to try out the latest version of the driver
so I used gspca-source to build my own module. When I install this
module I get the following message:

  dpkg - warning: downgrading gspca-modules-2.6.22-3-686 from 2.6.22+01.00.18-9 to 01.00.20-1+2.6.22-6.lenny1.

dpkg thinks that the freshly build module is older than the one provided
in the Debian package archive, where in fact it is not. Should I file a
seperate bug for this?

Please let me know if I can provide any other information that could be
helpful.

Best regards!

Jan
