Description Andi Valachi 2007-05-17 09:54:26 UTC

Version:           digikam-0.9.1-0.pm.1 (using KDE KDE 3.5.5)
Installed from:    SuSE RPMs
Compiler:          gcc-4.1.3-29 The current version for openSuSE 10.2
OS:                Linux

When creating a slide show, through the kipi-plugins in digikam, using the following settings:
Video Format: DVD
Video Type: NTSC
Chroma Mode: 420mpeg2 (default)
Transition Speed: 1
with sound track as well, everything works well but the first image in the slide show. The right side of the first picture has vertical colored lines - only in the right side. It appears as if it tries to transition from nothing to the first image. The first image should be not be processed for transition...
If you need anything else - ImageMagick version etc. please let me know. I checked and I am using the latest kipi-plugins 0.1.3, It's pretty much a vanilla openSuSE 10.2 kernel 2.6.18.8-0.3-default...

which mpeg player are you using?
I mean mplayer, keffeine etc. Could you please test
if both engines (xine and mplayer) have the same
behaviour?

Thanks,
	Angelo

digiKam has a new Video Slideshow tool based on QtAV and ffmpeg which do not
have this problem.
