[SOLVED] Video thumbnails / "previews" for dolphin 5?

Hi!

Can't figure out how to get video thumbnails / "previews" for dolphin 5. There is no "video" setting in dolphin preferences/general/previews. Thumbnails for other stuff (jpg, gif, mp3, folders, font files, text files) work. But videos, it isn't even trying (no option to enable / disable, no error messages). Prior to the recent "big kde update", everything worked fine.

I have installed:
- dolphin 15.08.0-1
- dolphin-plugins
- both phonon-qt4 and phonon-qt5 plus their gstreamer backends
- a lot of gstreamer plugins (tested in totem)
- kdemultimedia-ffmpegthumbs and kdemultimedia-mplayerthumbs (and mplayer + ffmpeg)
- kde-meta-kdeadmin 15.08-1
- kde-meta-kdebase 15.08-1
- kde-meta-kdesdk 15.08-1
- kde-meta-kdeutils 15.08-1
- kde-meta-kdewebdev 15.08-1
- probably  everything that remotely sounds like it could be related to making thumbnails by now.

I deleted ~/.thumbnails and rebooted after updating / installing additional kde packages, just to be on the safe side.

What am I missing?

Install this package:  https://aur.archlinux.org/packages/ffmpegthumbs-git

Re: [SOLVED] Video thumbnails / "previews" for dolphin 5?

Thanks, that one works!

*sigh* so... does that mean KDE just went ahead and released everything except an updated / working version of their official video thumbnailer plugin and I just have to wait for an upstream update after which I can remove the git version? Or is there a "cleaner" way I should be using to get the 15.08 version working properly now already?

edit: Also: Does it mean KDE isn't supporting /usr/share/thumbnailers/ anymore? I thought that was supposed to be a cross-DE standard

I think that the ffmpegthumbs slipped through the cracks. The ffmpgthumbs was ported to the KF5 about 11 months ago: https://git.reviewboard.kde.org/r/118545/ . You could file a bug report at the https://bugs.kde.org .

I don't know about the '/usr/share/thumbnailers/' but the KDE is using freedesktop specifications: http://freedesktop.org/wiki/Specifications/ and there the specification for storing file thumbnails: http://specifications.freedesktop.org/t … atest.html .

The KDE4 thumbnails: http://api.kde.org/4.x-api/kdelibs-apid … eator.html
and the KF5 thumbnails: http://api.kde.org/frameworks-api/frame … eator.html

The former

AFAIK KDE has never supported it

Re: [SOLVED] Video thumbnails / "previews" for dolphin 5?

Thanks for this solution, driving me nuts. Still  have to test it now ...
Can someone please elaborate. So i have these packages , they come with KDE. Not one , but FOUR.
And none of it does it's job ?

pacman -Qs kde thumb

local/kdegraphics-thumbnailers 15.08.0-1
    Thumbnailers for various graphics file formats
local/kdemultimedia-ffmpegthumbs 15.08.0-1 (kde-applications kdemultimedia)
    FFmpeg-based thumbnail creator for video files
local/kdemultimedia-mplayerthumbs 15.08.0-1 (kde-applications kdemultimedia)
    MPlayer based thumbnail generator for video files
local/kdesdk-thumbnailers 15.08.0-1 (kde-applications kdesdk)
    Plugins for the thumbnailing system

I remember years back that I had to install ffmpegthumbnailer to geet previews. Can someone fresh up my mind what those others packages are "actually"  supposed to do ?

Thanks, ahead!

Re: [SOLVED] Video thumbnails / "previews" for dolphin 5?

Just guessing here...:

local/kdegraphics-thumbnailers 15.08.0-1
... this one works fine and does the pictures?

local/kdesdk-thumbnailers 15.08.0-1 (kde-applications kdesdk)
... this one implements a new thumbnailing system?

local/kdemultimedia-ffmpegthumbs 15.08.0-1 (kde-applications kdemultimedia)
... this one doesn't create thumbnails with ffmpegthumbnailer because it doesn't support the new thumbnailing system ("yet" )?

local/kdemultimedia-mplayerthumbs 15.08.0-1 (kde-applications kdemultimedia)
... this one does the same as the previous one, except it uses mplayer to not make thumbnails instead of ffmpeg

( ffmpegthumbnailer puts a file in /usr/share/thumbnailers/ so all "independent" applications can use it, maybe also gnome. Which means I probably used it back in the olden days, when when xfce + compiz was still working/supported and already way better than the whole of KDE is today )

All those are (with the 15.08.0-1) for the KDE4. They are installing plugin libraries to the /usr/lib/kde4/ and the desktop part to the /usr/share/kde4/services/.

The KDE Frameworks 5/Qt5 is using for the plugin libraries: /usr/lib/qt/plugins/ and for the desktops:/usr/share/kservices5/.

For the Qt5/KF5 thumbnailers are from the package: kio-extras

$ pacman -Ql kio-extras | grep thumb
kio-extras /usr/lib/qt/plugins/comicbookthumbnail.so
kio-extras /usr/lib/qt/plugins/imagethumbnail.so
kio-extras /usr/lib/qt/plugins/jpegthumbnail.so
kio-extras /usr/lib/qt/plugins/kf5/kio/thumbnail.so
kio-extras /usr/lib/qt/plugins/svgthumbnail.so
kio-extras /usr/lib/qt/plugins/textthumbnail.so
kio-extras /usr/share/doc/HTML/en/kioslave5/thumbnail/
kio-extras /usr/share/doc/HTML/en/kioslave5/thumbnail/index.cache.bz2
kio-extras /usr/share/doc/HTML/en/kioslave5/thumbnail/index.docbook
kio-extras /usr/share/kservices5/comicbookthumbnail.desktop
kio-extras /usr/share/kservices5/directorythumbnail.desktop
kio-extras /usr/share/kservices5/imagethumbnail.desktop
kio-extras /usr/share/kservices5/jpegthumbnail.desktop
kio-extras /usr/share/kservices5/svgthumbnail.desktop
kio-extras /usr/share/kservices5/textthumbnail.desktop
kio-extras /usr/share/kservices5/thumbnail.protocol
kio-extras /usr/share/kservicetypes5/thumbcreator.desktop

A bug report: https://bugs.kde.org/show_bug.cgi?id=351894
