SOFTWARE VERSION: Maemo 5, 1.2009.41-10 STEPS TO REPRODUCE THE PROBLEM: Start any user-facing camera (/dev/video1) software, or simply gst-launch-0.10 v4l2src device=/dev/video1 ! ffmpegcolorspace ! autovideosink EXPECTED OUTCOME: Normal webcam image ACTUAL OUTCOME: There is a notable vertical band in on the left side of the image REPRODUCIBILITY: always EXTRA SOFTWARE INSTALLED: OTHER COMMENTS: User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:220.127.116.11) Gecko/2009090217 Ubuntu/9.04 (jaunty) Firefox/3.0.14

This: v4l2src device=/dev/video1 ! ffmpegcolorspace ! pngenc snapshot=1 ! filesink location=test.png avoids scaling and produces a file that can be examined. The band starts at around 123 pixels from the left. Can anyone suggest any tests that don't involve gstreamer?
(This can for example be seen in the "mirror" application in extras-testing repository.) Fixed in internal week 43 build. Any public update released with or after this build version (x.2009.43-y) will include the fix. Please verify that the new version fixes the bug by marking this bug report as VERIFIED after the public update has been released and if you have some time.
I can confirm myself that this is fixed in "mirror" running on the latest internal image.
For the record, mirror is using gstreamer (that's why I filed the bug here initially). An independent test is for example something along the lines of mplayer tv:// -tv device=/dev/video1
*** Bug 5944 has been marked as a duplicate of this bug. ***
I can confirm this as FIXED in 2.2009.51-1, BUT... The camera quality seems even worse than before and there are many static "dead" pixels that remain onscreen, regardless of external ambient light. Should this be reopened, or should a new bug be filed?
I can confirm this has been fixed in 2.2009.51-1 and confirm also that there are "dead huge pixels" in the image. The quality of the image using 'mirror' is mostly the same, may be a bit darker (compared with two n900s one next to each other with firmware 42-11 and 51-1)
With 44-1 firmware, I still have this issue, even though according to #2 it should be gone.
Sorry for being misleading here. The fix is not included in 1.2009.44-1, but will be included in the next 2.2009.** release (PR1.1).
The problem reported here should be fixed in the update released today for public: The Maemo5 update version 2.2009.51-1 (also called "PR1.1" sometimes). Please leave a comment if the problem is not fixed for you in this update version.

Verified, dark band gone in 51-1. As the OR I'd say missing/weak noise reduction is a different issue as to what was reported here, but if you say it's simpler to keep it here, feel free to reopen.
(In reply to comment #12) > if you say it's simpler to keep it here, feel free to reopen. Nah, this report here is about the band only. And that's fixed.
