Subject: gspca-source: Cam delivers a very narrow field of view in flash applets

Date: Thu, 28 Feb 2008 17:54:30 -0700

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.camorama.png
  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:

  http://www.unitzeroone.com/old/eightball/motionDetection/

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

I simply have no idea about the problem at hand, sorry. Flash sucks, and is not
present on any of my systems, nor am I intimately familiar with the inner
workings of the gspca webcam driver, despite making it available for others
in form of debian package.

IIRC, this was once discussed with the maintainer of the linux-modules-extra
stuff, but I can't recall what was said. It would be worth asking the
maintainers of the conglomerate module packages why this is so.

Thanks, Kel.

Thx for your reply, Kel. I didn't think of it when I first reported this
bug, but should I maybe file this bug against the flash package instead?
(if so, what is the best way to do that? File a new bug or do some fancy
reassignment using the Debian BTS?)

Regards!

Dunno, your choice. Its not like the flash maintainer can possibly fix the
problem though.

The gspca package has been removed from Debian so we are closing
the bugs that were still opened against it.

For more information about this package's removal, read
http://bugs.debian.org/519463 . That bug might give the reasons why
this package was removed, and suggestions of possible replacements.

Don't hesitate to reply to this mail if you have any question.

Thank you for your contribution to Debian.

Kind regards,
