camorama swaps red and blue channels

[Robert Persson]

Binary package hint: camorama

On my (Edgy) system Camorama swaps the red and blue channels. This means, for instance, that my skin looks blue and my cool grey cardigan looks more a burnt Sienna. Green looks green though.

On the same system, using the same webcam, Ekiga displays colours correctly. However two other applications have their own problems with this camera. Linphone 1.5.1 (compiled from source against edgy libraries) gives up on each frame about half way down, so that you only see the top half of your head. GyachE (installed using automatix) sometimes flickers the top ten percent of the image for a moment and then gives up altogether and shows an empty white box and sometimes just shows the white box straight away. I mention these problems just in case they might be relevant.

The camera is a Logitech Quickcam Chat. I am using the driver developer's latest driver (gspca) because the spca5xx driver that shipped with Edgy seems to be broken altogether. I am using a kernel compiled from vanilla 2.6.19.1 sources.

I can confirm this in the latest version of camorama in Feisty.
Colors are perfect in aMSN but red and blue are swapped in Camorama.

A pic of a coke can is attached. I think we all know how it should look :)

I must apologize.
My cam info is:

Bus 003 Device 002: ID 046d:08f0 Logitech, Inc. QuickCam Messenger

I was looking into other apps and I found that gqcam also gets the red and blue mixed.
The solution in gqcam is using the --swap command on run which swaps RGB to BGR

I assume that aMSN's capture software detects this automatically.

I have attached the output of "camorama -D"

Adding the "color correction" effect is an interim fix.
Sorry that I have made so many comments.

The colour swapping also occurs on my system. I am running the beta xubuntu with camorama and a Creative NX Pro webcam.

Color swapping also here: using gspca-source 0.10012.1, Ubuntu feisty.
xawtv works and ekiga work ok.

I am confirming the bug in feisty. Other apps like ekiga, openwengo and web flash applications show the color fine. It seems also like blue and red is swapped.. is there a fix?

[Chris Mostert (cvmostert)]

I could correct the color problem by doing this:
Ctrl+E to view effects, right click and add filter -> Color Correction.
Hope this helps someone.

I can confirm that this Colour Correction filter has fixed the issue with my webcam and camorama. Thanks

I'm marking as fix released as stated by the last comment

Thanks for your bug report
