Thumbnails are created for all video files, regardless of size (limit)

[Peter Parkkali]

Nautilus creates preview icons for all video files, even if there's a size limit set in the preferences (Preferences -> Preview -> Only for files smaller than .... kB/MB).b

I have totem-xine installed instead of totem-gstreamer.

My installation is Dapper, with all the latest upgrades installed (clean install with /home from 5.10)

Here's output from 'gconftool --dump /apps/nautilus' in case anyone needs it.

Thanks for your bug. That's not a bug, the preference limit is for images only because you need to download the image to do a preview, there is no need to download the video to make a preview of it. The setting is not that clear but there is already some bugs on the topic, no need to keep that one, I'm marking it as rejected, feel free to reopen if you disagree

Still the case on 8.04 beta.
Just wanted to give it a little attention - given the date this "bug" was first reported.

I feel this is a bug. Previewing video files slows my systems down immensely, and so I have to turn off previewing altogether, which causes me to lose image thumbnails as well. Video previewing should respect the size limit. Alternatively, video previewing should have its own set of options distinct from image previewing.

This is realy a bug as I can't see content of the folder. Nautilius is trying endlessly to generate thumbs for some videos and hangs in that state. I have set limit to 10 MB, videos are 30 to 60 Megs...

[A. Walton (awalton)]

The limit only applies to image formats, as Nautilus does not actually thumbnail videos (gnome-video-thumbnailer, which is just a special way of calling Totem, does). The limit imposed by Nautilus will never apply to videos, since it does not make sense to do so; thumbnailing a video only renders one frame of the video about 30 seconds in, whereas thumbnailing images requires reading the entire image file and then scaling it down to thumbnail size.

[Pawel Bednarski (pavkong)]

But still it hanged. And does not show me content of the folder making me upset. It is making ubuntu useless and not the desktop os. As an user I expect it to be:
a) operable (it displays my folder content!)
b) logical (when it says (in context of size) about other file types it says about other types and not excluding video files not stating that!)
So fix it or state in description that this limit is not about videos. And if not about vides let me disable thumbs generation for videos.

[Sven Hoffmeister (schaumkeks)]

If the thumbnailer hangs, this is a problem with specific files. Wasn't there a timeout of 30 seconds?
Anyway, you can disable thumbnail generation per mime-type in gconf. Have a look at the comment by Sebastien:

To mark this Invalid is completely wrong if you ask me. You would have to change the dialog in Nautilus to say "Don't make thumbnails for IMAGES larger then" rather then just chuck it under "Other previewable files".
This very much feels like a bug to the ordinary user who has no concept of what it entails to make thumbnails of this or that file and shouldn't have to!
