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

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 .

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.

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.

Re: Video Previews

"These are not really standards"

> freedesktop.org - Specifications >> Thumbnail Managing Standard:

Information of:

• Thumbnail Directory
• Thumbnail Attributes
• Thumbnail Size
• Thumbnail filename
• Deleting Thumbnails
• etc...

The KDE and KDE programs are more or less using the freedesktop.org specifications.

Misc Links:
> KDE ThumbCreator Class Reference
> KPhotoAlbum - Summer vacation means much faster thumbnail viewer.
> Bug 79943 - it should be possible to limit the amount of disk space used by thumbnails (.thumbnails directory)
> Bug 145301 - There is no (GUI?) way to limit thumbnail cache size or age


“All animals are equal, But some animals are more equal than others.”

> KDE ThumbCreator Class Reference:

The following optional property can also be added to the .desktop file:
ThumbnailerVersion=N

where N is some nonnegative integer. If a cached thumbnail has been created with a previous version of the thumbnailer, then the cached thumbnail will be discarded and a new one will be regenerated. Increase (or define) the version number if and only if old thumbnails need to be regenerated. If no version number is provided, then the version is assumed to be <0.

Looking the KDE 4.5 / Maverick video thumbnailers:

"ffmpegthumbs"

cat /usr/share/kde4/services/ffmpegthumbs.desktop

=> ThumbnailerVersion=2

"kffmpegthumbnailer"

cat /usr/share/kde4/services/kffmpegthumbnailer.desktop

=> ThumbnailerVersion=1

"mplayerthumbs"

cat /usr/share/kde4/services/videopreview.desktop

=> The "ThumbnailerVersion" is not set


Summary: Thumbnails made by the "mplayerthumbs" are replaced by the "kffmpegthumbnailer". And the "ffmpegthumbs" is replacing thumbnails made by the "mplayerthumbs" or the "kffmpegthumbnailer".


Uniform appearance

It is possible to mix the different thumnails made by the diffrent thumbnailers if the "ThumbnailerVersion" is same in the video thumbnailer desktop files.



But the outlook is incoherent. The mplayerthumbs is using a stripe on the left edge.
The ffmpegthumbs (~kffmpegthumbnailer) is using the crapes on the both edges.

With small changes it is possible to set the thumbnailers to make uniform thumbnails.

> mplayerthumbs-alternative

- The filmstrip pattern has been disabled as default.
- The mimetype icon is blended over the preview image.
- Set the ThumbnailerVersion=1


> ffmpegthumbs-alternative

- The filmstrip pattern has been disabled.
- The mimetype icon is blended over the preview image.
- Set the ThumbnailerVersion=1


Mixing thumbnailers - removing selected thumbnails

The thumbnails are in the ~/.thumbnails/large/ and ~/.thumbnails/normal/. Thumbnail name is the MD5 hash for the file URI > Thumbnail Saving

With the non "ASCII" directory/filenames the URI should be escaped/encoded (space is %20 etc...) before the MD5 hash.



File is /media/sda6/Temp/MD5 test ÄÖÅÜ.mov

The exif information of the thumbnail is telling:

...
File Name : 83d57d464b3dacb4b26f785ac900415a.png
Directory : /home/rog/.thumbnails/large
...
Software : KDE Thumbnail Generator Video Files (MPlayerThumbs) (v2)

Re: Video Previews

strangley the kffmpegthumbnailer would not produse a option in...... Dolphin/Konqueror > Settings > Configure Dolphin/Konqueror > General > Show previews for.........

wether installed from synaptic or with your ppa packages and Gdebi

Hmm - strange

A .desktop (> GtoK: .desktop files) file should be enough to show the option.




A)
Did you log out-log in after the installation ? - sometimes this is needed to get the KDE register new applications.

B)
With the kffmpegthumbnailer do you have ?
/usr/share/kde4/services/kffmpegthumbnailer.desktop
and
/usr/lib/kde4/kffmpegthumbnailer.so

C)
Have you tried with the Lucid (KDE 4.4) package ?

Re: Video Previews

Thank you Rog131

the mplayerthumbs and z166-kde4-ffmpeg-thumbnails are working just great.

and yes the mplayerthumbs dose use the CPU .........but onley for a few moment's then it calms down

strangley the kffmpegthumbnailer would not produse a option in...... Dolphin/Konqueror > Settings > Configure Dolphin/Konqueror > General > Show previews for.........

wether installed from synaptic or with your ppa packages and Gdebi

but the other 2 work a treat

Re: Video Previews

but witch one (of the last 2)would YOU recomend for a Karmic 9.10 runing KDE-4.4.0 (I do have a working ffmpg and mplayer-mencoder )

It depends (these are subjective things):


What do you have ? (low/high end computer - here low end)

- the mplayerthumbs needs lot of CPU power - it is slow at here.

- the kffmpegthumbnailer and the z166-kde4-ffmpeg-thumbnails (1) are equally fast and light.


What do you want ?

- the mplayerthumbs (2) can show continous preview images when you hover the mouse pointer over the icon.

- the mplayerthumbs can thumbnail everything the mplayer can play.

- the z166 can thumbnail a bit more than the kffmpegthumbnailer.
- the z166 is showing more black thumbnails than the kffmpegthumbnailer.


It depends = you need to test.


(1) z166-kde4-ffmpeg-thumbnails-0.1 later z166
(2) mplayerthumbs-alternative (3) can't show continous preview images with the KDE 4.4.
(3) mplayerthumbs-alternative:
This is a recompile of the mplayerthumbs (1.2) from the Kubuntu 9.04.
This version is faster than the mplayerthumbs (1.2-kde4.3.2-0ubuntu1) or mplayerthumbs (4:4.4.0-0ubuntu1).
