Dolphin - Video & Pdf Files Preview

[Burner2k]

Hello,
Did a fresh upgrade from Kubuntu 15.04 to 15.10. Since I wanted previews for video & pdf files in Dolphin, installed the following from Muon:

1. ffmpegthumbnailer
2. kffmpegthumbnailer
3. mplayerthumbnailer
4. kdegraphics-thumbnailers

pre
Opened Dolphin -> Settings -> Config Dolphin -> General -> Preview and I see no option to check preview option for video or PDF files. When I installed Kubuntu 15.04, I followed the above procedure and was able to get previews for both video & pdf files. I am unsure if Dolphin version shipped with 15.10 is unable to show previews even with the above packages installed or am I missing something!

It is important for me to get preview of video & pdf files. Please help in getting the same. Let me know if I need to post any further information to help this issue resolved.

Bug 351894 - Missing video thumbnails after upgrading to 15.08: https://bugs.kde.org/show_bug.cgi?id=351894
--> Ubuntu: https://bugs.kde.org/show_bug.cgi?id=351894#c10

Bug 351913 - since version 15.08 some file types previews no longer available (pdf for instance): https://bugs.kde.org/show_bug.cgi?id=351913


Workarounds:

Use the older KDE4 version of the Dolphin - Package: dolphin4: http://packages.ubuntu.com/wily/dolphin4
Use the Konqueror file manager. It is KDE4.

LinkBot,
Thanks for replying.

Its is quite frustrating as an end user to see some outstanding bugs making its way into major releases. I tried installing Konqueror via apt-get install Konqueror and it did install successfully but I get nothing when searching for the same.

Can you please guide me on how to install Konqueror file manager?

Regards

The command:

sudo apt-get install konqueror

Should install the Konqueror: http://packages.ubuntu.com/wily/konqueror

Should start with command:

[FONT=monospace]konqueror --profile filemanagement[/FONT]

Konsole/krunner/etc.. can be added to the KDE menu.


About Dolphins

Both the new Dolphin (KF5) and the Dolphin4 can be installed side by side.




The Dolphin4 will start with command: dolphin4 (konsole/krunner/etc..)

Thanks LinkBot,
I launched Dolphin4 and previews are back

Do you know how I can create a shortcut and make dolphin4 the default file manager instead of the latest version?

[LinkBot]

One way to set the Dolphin4 as the default file manager

Add the Dolphin4 to the KDE menu: https://docs.kde.org/trunk5/en/kde-w...dit/index.html




Change the default file manager: https://userbase.kde.org/System_Sett...t_Applications

KDE System Settings > Applications > Default Applications

Linkbot,
I was just about to post that I've figured out answers to both of my questions. But thanks for explaining the procedure with illustrations.

Hi,
I have just one more issue. I created a Trash widget on my desktop. Now when I double click on the trash icon, I get an error message "Malformed URL trash:/" and followed by another message "KDEInit could not launch /usr/lib/x86_64-linux-gnu/libexec/kf5/kioexec". I can however empty the trash from the desktop but unable to open the folder and view its contents. Any suggestions on how to fix the same?

It seems that...



Same error/problem at here. It seems that the plasma5/trash plasmoid can't comprehend the KDE menueditor desktop files.



A workaround, working at here, is to make the desktop file by hand.

Using the KDE4 dolphin.desktop file as template: https://projects.kde.org/projects/kd...olphin.desktop

1) Making ~/.local/share/applications/dolphin4.desktop

[Desktop Entry]Name=Dolphin4
Name[x-test]=xxDolphin4xx
Exec=dolphin4 %u
Icon=/home/linkbot/Pictures/Dolphin-icon.svg
Type=Application
X-DocPath=dolphin/index.html
Categories=Qt;KDE;System;FileTools;FileManager;
GenericName=KDE4 File Manager
GenericName[x-test]=xxKDE4 File Managerxx
Terminal=false
MimeType=inode/directory;
InitialPreference=10

2) Rebuilding the KDE system configuration cache:

kbuildsycoca5 --noincremental

3) Choosing the default file manager.

So the default dolphin shipped with wily still doesn't have video preview ? That's crazy !

It is annoying to have these little bugs but Wily is basically a Minor release, the present Major or LTS release is 14.04.3, the next is expected to be 16.04 or Xenial Xerus.
KDE is going through a major architecture change so we can only hope these bugs will be ironed out by coming April.

And it seems not everyone values previews
