Yeah, this is something hard. We try to use some tricks, like opening images at 1/2, 1/4 or 1/8 if they are JPEG, since this is possible and should not take much memory, but 18mpx is quite a lot, even in that case.

How long did you wait? They have a timeout of 30 seconds (maybe more, I didn't write this and last time I checked was long ago). They listen for DBus's NameOwnerChanged and when last user disconnect they'll wait that amount before shutting down. This is in the case user wants to quit Canola for some reason and quickly restart it, you'd not have to wait these daemons to load.

And what kind of solution do you propose? Not clear to me.

(I got Ogg working now, because I knew about the lightmedia-scanner-Canola relation, but many users may not).
Yes, our bad. We forgot to upload 2 packages: applet and ogg. With them it would make more sense :-)

Whenever I add new videos and want to have thumbnails created for those as well, I need to go through the whole process of creating >150 thumbnails again. Time for another cup of coffee... :/
Video thumbnail is also tricky... it's hard to figure out correct frames and all. And this is done by Canola-Tuning, since it uses MPlayer, we cannot force Canola to depend on it and thus we cannot request on demand, as we do with picture thumbnails.

Unfortunate situation :-/ But good to know nonetheless.

Weird, this should work. Anyway, that code is open and you can freely check what's up with it. Patches are welcome ;-)

Image panning in the image viewer is not kinetic, so doesn't really fit the rest of the user interface...
This is on the roadmap for next release. We have few things to do, possibly you will like it.

No, it's actually a bit faster and you can even see some animations you could just see on desktop before. But that changed the flickering/tearing effect and in some screens they're even more noticeable. This is specially true for photo-walls, now we use asynchronous image loading, so we block much less and we load much more images than before, animation is bit faster and these together give the impression it's jerky, weird, we know... trying to solve by changing some constants to match these problems.
