The ffmpegthumbs-mattepaint is an alternative version of the standard KDE ffmpegthumbs. The ffmpegthumbs-mattepaint (0.4) is based on the ffmpegthumbs git revision 77eeb2e9.

Both the ffmpegthubs and the ffmpefthumbs-mattpaint can be installed side by side.

The ffmpegthumbs-mattepaint:

* is using the QPainter & QImage to draw the thumbnail decorations.

* is using pseudo-random number to seek the preview image (5%..95%).

* is using the ThumbCreatorV2.

* can use external images as the thumbnails.

* can use the KDE service menus to add/remove the thumbnails.

The thumbnail decorations are loaded from the image files (.png) so the user can draw own decorations.

The user decides if there will be:

* a pure image thumbnail.

* a thumbnail with the blended mime icon.

* a thumbnail with the matte picture(s).

Preview Clips:

Thumbnail decoration: http://youtu.be/MXZPEvA6rW4 .

Using KDE service menus: http://youtu.be/8Dldote6uiI.

Adding the Matroska embedded art to the thumbnails: http://youtu.be/_lqS5ww8di8.

Hand picking the Matroska embedded art: http://youtu.be/08Dzz-Vc8Ik.


The compilation is depending same development files as the standard ffmpegthumbs.

The generic compilation:

1) cd /to/the/ffmpegthumbs-mattepaint/

2) mkdir builddir

3) cd builddir && cmake .. -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix`

4) make

5) sudo make install

Compilation example:http://pastebin.com/gg82KwrU.

HowTo / Readme

A short readme is included in the archive: .../ffmpegthumbs-mattepaint-0.4/readme/readme.html

Known issues with the 0.4

- The normal (128) and the large (256) thumbnails are made separately so they can be different images. A workaround is to symlink the thumbnail subdirectories.

Only guarantee: No harm intended...


0.4 / 2014-02-09

- Use KDE ThumbCreatorV2. Adds option enable/disable the matte pictures from the checkbox.
- An option to use all (QImage supported) images as the thumbnails.
- Example scripts to use the attached Matroska posters as thumbnails.

0.3.1 / 2013-03-27

- Remove the test build option.
- Clean the perl scrips.

0.3 / 2013-03-24

- More randomness with the qsrand().
- An option to use png images as the thumbnails.
- Example scripts to hand pick the thumbnails: Snapshot from VLC & SMPlayer, Use posters or any png image as the thumbnail .

0.2 / 2012-09-12

- Don't draw frames around the preview image.
- Use the KDE standard dirs.
- Scale the ornaments with the normal thumbnails.

0.1 / 2012-09-08

 Pretty cool

great idea, i just tested it on archlinux KDE 4.9.1 and it works (kind of) :)

The thumbnails are there but i noticed two problems.

1. When the preview thumbnail is smaller than 94px (dolphin settings) the mimetype icon is to big. It is as high as the whole preview thumbnail.

2. Even after creating ".kde4/share/apps/ffmpegthumbs-mattepaint" the mimetype icon is shown. If i got you right that should not happen.

I made a archlinux PKGBUILD: https://aur.archlinux.org/packages.php?ID=62671

Keep up working on this, great work!

Thank you. Good points.

#1: Yes the ffmpegthumbs-mattepaint is using same ornaments for the normal(128x128) and the large(256x256) thumbnails. With the normal thumbnails the ornaments are too large. Addded to the ToDo list ;) .

#2: I can't reproduce this. Here the mimetype icon is shown only if there is no ~/.kde/share/apps/ffmpegthumbs-mattepaint/. A flash clip: http://www.dailymotion.com/video/xtg5yj_blended-icon-thumbnail_tech (and the other clips).At here KDE 4.7...4.9.0.

Have you tried to clean the thumbnail directory with the sweeper ?

Ah now i got it.

You are checking for the hard coded directory ".kde/share/apps/ffmpegthumbs-mattepaint/" but my KDE config files are located in ".kde4". You should use "kde4-config --localprefix" to get the correct config dir.

After changing the directory it works. :)

Two more suggestions:

Just to let you know, the quadrant images are also to big in smaller preview images. (Not sure if its the same "problem" as with the icon)

There is a strange white line at the left and at the top of each preview image. Would be nice if that got removed.

You can see both problems here: http://i.imgur.com/Sa3Qm.png

Comments/suggestions welcomed

#1 The path - Yes I should use the kde standard dirs (kstandarddirs) -> added to the ToDo

#2 The normal thumbnails should use a scaled ornament or read a smaller one.

#3 The "white line" is a KDE frame. I should use the "None" not the "DrawFrame" -> added to the ToDo

The CMake error with the option "KDE4_BUILD_TESTS=ON" is a leftover from the original ffmpegthumbs -> cleaning the code.

The build with the 0.3 will succes if you dont'use the "KDE4_BUILD_TESTS" option.

With the 0.3.1 the leftover is removed - with the "KDE4_BUILD_TESTS" option there will be warning:

"$ cd builddir && cmake .. -DKDE4_BUILD_TESTS=ON -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix`

CMake Warning:
Manually-specified variables were not used by the project:

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
