Steps to Reproduce:
1. Start cheese.

Fixes the described problem.
This patch adds the following:
- when falling back to a v4lsrc GStreamer source, disable autoprobe-fps.
- Also try a YUV stream in 320x200 mode.
This fixes my problems with the Logitech QuickCam Pro 5000.
I am not sure how compatible this fix is with other webcams. The YUV probe should not be a problem.. Turning off the FPS auto-probing might be more problematic.
I meant Logitech QuickCam Pro 4000 in comment #1 (not 5000 as I wrote).
The cheese which we have in F-8 is a very early test release (as the version no signals). F-10 (beta) has a much much better version. If you are interested in cheese, and want to write patches to improve it, you really ought to start with the F-10 version.
Note BTW that there is a bug in the pwc driver which may get triggered in combination with libv4l which cheese use in F-10. I'm working on a workaround for this for libv4l (and I'll file a bug against the pwc driver). Things should work with libv4l-0.5.2, which should be in rawhide tomorrow or they day after.
In the mean time I think this bug can be closed as wontfix given the old version of cheese in F-8 and that F-8 is nearly EOL, mclasen what do you think?
Yeah, yeah, I know. You guys are not interested in fixing the "old" F8.
Guess what? I'm not interested in beta-testing F10 yet either.
Close the bug if you want. I fixed it in my personal repo, now other people that will encounter the problem will have it documented somewhere.
I'm still wondering whether or not I should keep reporting bugs. Either they get closed with the "upgrade to $LATEST" or they just get ignored.
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '8'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.

Thanks for reporting this. I own a Logitech QuickCam Pro 4000 now myself these
days, and I've been able to reproduce this, it turns out this actually is a
gstreamer-plugins-good bug. I've filed a bug report with a patch upstream:
And I've fixed this in the rawhide / Fedora 12 gstreamer-plugins-good packages version 0.10.15-6 and later.
Thx f. sharing this!
