Description René Krell 2009-01-30 11:39:05 UTC

Version:           0.10.0-rc1 (using 4.2.00 (KDE 4.2.0) "release 83.1", KDE:KDE4:Factory:Desktop / openSUSE_11.1)
Compiler:          gcc
OS:                Linux (i686) release 2.6.27.7-9-default

Playing back AVI videos from a digital camera results shows them in a wrong, obviously strongly reduced color palette. There are extreme contrasts and the colors are falsificated. In comparison if I start the same video in DragonPlayer it is played back as expected.
This happens using both, gstreamer and xine Phonon backend, without difference.
I cannot take a snapshot from it at the moment, since ksnapshot shows me only black background. The only way is take a photo of the screen with a digital camera. If you don't have any imagination about what I'm talking about here I will provide a snapshot later.
Thank you

I can confirm this. The "initializing main view" makes the video playback hue to change invert colors. This can be fixed only by restarting the player or then configuring the video controls hue to opposite.

So something triggers on the digiKam start, videoplayback to change hue.

I still have the problem with the latest updates of the KDE 4.2 Factory repo for OpenSuSE 11.1. Playing a bit with the backends XINE and GStreamer i found, that the wrong colors happen with the XINE backend in both cases, Digikam and DragonPlayer, while using GStreamer it is shown badly only in Digikam, but not in DragonPlayer.
Using KDE 4.2.00 (KDE 4.2.0) "release 99", KDE:KDE4:Factory:Desktop / openSUSE_11.1
The video clips I use for this come from the digital camera Olympus Mju, there's an example here:

Comment 3 René Krell 2009-03-16 11:38:34 UTC

Works for now reliably with KDE 4.2.1, Phonon 4.3.1 using XINE, xine 1.1.16.2.

Comment 4 caulier.gilles 2018-08-21 13:57:01 UTC

This problem is not reproducible since digiKam use QtAv framework + ffmpeg to handle video files
