[KDE4 Dolphin] Video previews

I’ve installed KDE4.1 from Factory repo (working fine), however I cannot get dolphin to generate video thumbnails.
I also tried to install mplayerthumbs: MPlayerThumbs KDE-Apps.org
which I use it on KDE3 (great app), but it doesn’t seem to be working at all (compilation and installation went fine).

please try the following:

Extract mplayerthumbs and change to that directory, in my case /Desktop/mplayerthumbs-1.1 and change the path of the last command

horst@linux:~/Desktop/mplayerthumbs-1.1> export QTDIR=/usr/share/qt4                                                               
horst@linux:~/Desktop/mplayerthumbs-1.1> export KDEDIR=/usr    
horst@linux:~/Desktop/mplayerthumbs-1.1> export KDEDIRS=$KDEDIR
horst@linux:~/Desktop/mplayerthumbs-1.1> export KDE_BUILD=$KDEDIR                                                                  
horst@linux:~/Desktop/mplayerthumbs-1.1> export DBUSDIR=$KDEDIR
horst@linux:~/Desktop/mplayerthumbs-1.1> export LD_LIBRARY_PATH=$QTDIR/lib:$KDEDIR/lib:$LD_LIBRARY_PATH                            
horst@linux:~/Desktop/mplayerthumbs-1.1> export PKG_CONFIG_PATH=$DBUSDIR/lib/pkgconfig:/usr/lib/pkgconfig                          
horst@linux:~/Desktop/mplayerthumbs-1.1> export PATH=$QTDIR/bin:$KDEDIR/bin:$PATH                                                  
horst@linux:~/Desktop/mplayerthumbs-1.1> cmake -DCMAKE_INSTALL_PREFIX=$KDEDIR -DCMAKE_BUILD_TYPE=release /home/horst/Desktop/mplayerthumbs-1.1

then run make and make install.

Output should look like this (x86-64):

linux:/home/horst/Desktop/mplayerthumbs-1.1 # make install

Hope that helps

I already found out that I was using old prefix, just forgot to post the solution here.

It works superb (very fast thumbnail generation)!

Do you have the information panel enabled in dolphin ?

The preview in that panel is really slow here, but i think that’s related to dolphin.

@MonsterM: no, preview panel makes dolphin freeze on videos.
If you know how to fix this / or just disable video previews in that panel, please tell.

Should be fixed in 4.1

Bug was caused by strigi and is fixed with the latest update.

Very cool to see random previews in the info panel …
