Shortly:

The Nepomuk TV Namer is an information and poster retriever for the TV shows. The information is retrieved from the http://thetvdb.com/ with the libtvdb: http://sourceforge.net/projects/libtvdb/.

The posters are saved to the ~/.kde/share/apps/nepomuktvnamer/banners/<TV Show name>. The TV show information is saved to the Nepomuk database.

The KIO tvshow will show the banners and the information for the indexed TV shows,




Working with the KDE 4.8+. Tested with the Kubuntu 12.04 (alpha2), KDE 4.8.0; patched kdelibs.

About

As the names are suggesting:

http://packages.ubuntu.com/precise-u.../mplayerthumbs

video thumbnail generator using mplayer

http://packages.ubuntu.com/precise-updates/ffmpegthumbs

video thumbnail generator using ffmpeg

Both thumbnailers are from the KDE: https://projects.kde.org/projects/kde/kdemultimedia .

The third option:kffmpegthumbnailer; http://packages.ubuntu.com/precise/kffmpegthumbnailer .

The KDE-Apps (http://kde-apps.org/content/show.php?content=117562) is telling:

Hallo i added kffmpegthumbnailer into kde. I think that kde sc 4.5 will ship it. Thanks for your great work!

So ffmpegthumbs~kffmpegthumbnailer.


There are differences:

- the Dolphin is using the mplayerthumbs to make the video thumbnails on directory icons.
More: http://www.kubuntuforums.net/showthr...=mplayerthumbs

- the mplayerthumbs is slower (but the thumbnails are better):

Speed test

Writing a small timing script (perl):

#!/usr/bin/perl

use strict;
use warnings;
use Time::HiRes qw( usleep ualarm gettimeofday tv_interval nanosleep
		      clock_gettime clock_getres clock_nanosleep clock
                      stat );

# path to the thumbnail directory (large)
my $dir = ("/home/oneline/.thumbnails/large/");
# number of video files
my $stopCount = (147);

my $count = (0);
my $timerSet = (0);
my ($startTime); 

while ($count < $stopCount) {
   if (($count > 0) && ($timerSet == 0)) { 
      $startTime = gettimeofday;
      $timerSet = 1;
   }
   my @files = <$dir/*>;
   $count = @files;
}

my $endTime=gettimeofday;
print "Time: ", $endTime-$startTime, " s \n";

Testing:

1. Sweeping the thumbnails with the KDE sweeper (history and temporary file cleaner).
2. Starting the timing script.
3. Clicking the preview on.

Results with the 147 video clips:

ffmpegthumbs: 10.9209570884705 s, 10.8654680252075 s, 10.9800579547882 s.
mplayerthumbs: 184.332983016968 s, 226.345067977905 s, 233.901187896729 s.

Kubuntu 12.04, KDE 4.8.3, 64 bit.

FFMpegThumbs-MattePaint

http://kde-apps.org/content/show.php...content=153902

The ffmpegthumbs-mattepaint is an alternative version of the standard KDE ffmpegthumbs.

Both ffmpegthums and ffmpefthumbs-mattpaint can be installed side by side.

The user decides:

* If the ~/.kde/share/apps/ffmpegthumbs-mattepaint/ directory exists but there are no ornament images: only the bare preview thumbnail is made. A flash clip: http://www.dailymotion.com/video/xtg...thumbnail_tech

* If the ~/.kde/share/apps/ffmpegthumbs-mattepaint/ directory does not exists: the mimetype icon is blended over the preview thumbail (http://api.kde.org/4.x-api/kdelibs-a...mbCreator.html). A flash clip: http://www.dailymotion.com/video/xtg...thumbnail_tech

* If the ~/.kde/share/apps/ffmpegthumbs-mattepaint/ directory exists and there are ornament images: the preview thumbnail is made with the wanted ornaments. A flash clip: http://www.dailymotion.com/video/xtg...thumbnail_tech

The traditional filmstrip holes: http://www.dailymotion.com/video/xtg...thumbnail_tech

Known issues / ToDo

The ffmpegthumbs-mattepaint is using same ornaments for the normal(128x128 )/large(256x256) thumbnails. With the normal thumbnails the ornaments are too large. Addded to the ToDo list . More of the thumbnails: http://www.freedesktop.org/wiki/Specifications -> http://specifications.freedesktop.or...ec-latest.html

Only guarantee: No harm intended...

In Dolphin's 'gear-wheel' menu -> Configure Dolphin -> General -> (Behaviour Tab) tick the box that says "Show tooltips".

Nah, there are soooo many different things to tweak & tinker with in KDE... I bet there aren't many people who know them all.

I usually find tooltips to be annoying and distracting, so I turn most of them off... but this is one of the few that I do like, which is the only reason I knew how to enable that effect

Thanks for that - searching on this forum throws up lots of good information!!

I've read too many good fun tips for Dolphin today, I really need to write them all down!!

Automatic audio preview when the mouse is over the file

The Dolphin is having the tooltips (Dolphin > Settings > Configure > General > Show tooltips) which will show the preview image (if enabled) and the file information. The tooltip can be tuned to play the audio file on background.
