Since I've upgraded to KDE 4.7 (Ubuntu Natty with Backports) - I can't get the Gwenview video thumbnailing to work. It was working before and I miss it lots.

I was using the mplayer thumbnailer before and have tried uninstalling that and using others in it's place (kmpegthumbnailer, ffmpegthumbnailer, ffmpegthumbs) - but none of them seem to work at all.

Is there some other config I need to do, or is there a specific thumbnailer it should use - or is it broken until I go to Ocelot?

Well, after upgrading to Oneiric Ocelot - I have the same problem.

I can get video thumbnails in Dolphin, but not in Gwenview.

Same problem here, thumbnails were fine with 11.04 and ffmpegthumbnails. Stopped working with the upgrade to 11.10 and now no thumbnailer seems to work. Can't find any debug-output regarding this problem, .xsession-errors doesn't show anything.

Greetings,

Same here but with Arch running 4.7.2. I would guess something broke in Gwenview during the upgrade to 4.7.

You have to build gewnview for yourself but it was quite straightforward with ubuntu, the main steps are:

- apt-get source gwenview
- apply patch by hand, its only two files and several lines of code...
- change first line of debian/changelog: the string "ubuntu1" to "ubuntu2"
- sudo debuild
