Description: kffmpegthumbnailer is a video thumbnailer for kde based on ffmpegthumbnailer. The thumbnailer uses ffmpeg to decode frames from the video files, so supported videoformats depend on the configuration flags of ffmpeg.
This thumbnailer was designed to be as fast and lightweight as possible.Last changelog:
version 1.1.0 (January 6, 2010) - Updated to ffmpegthumbnailer 2.0.0 interface
version 1.0.1 (December 28, 2009) - Fixed thumbnails not being generated for filenames containing non-ascii characters (Thanks to fedux.c)
Version 1.0.0 (December 24, 2009) - Initial release
Hi,
I like kffmpegthumbnailer very much. But there's a problem when downloading bittorrent files. If I have a dolphin window open showing the directory of the downloaded files, kio_thumbnail eats all my memory and the pc gets unusable.
Any ideas?
I'm using kffmpegthumbnailer 1.1.0 with libffmpegthumbnailer4 2.0.2 and KDE 4.4.4
I'm trying to compile, but I get this error:

Hi ...
Why does the video preview inside Folderview has not the same size such as in Dolphin? In Folderview it is ugly small (looks like icon size?), while it is being displayed in dolphin much bigger. It would be nice if you could change that.
In addition, it would be also great if the info window (when I hover a video file in Folderview) would display an even bigger preview, just like the images previews do it.
No you failed to install the ffmpegthumbnailer library properly. Just wait to install the new version untill ubuntu updates the ffmpegthumbnailer package.
welll i have install ffmpegthumbnailer like written in the wiki and it works rigth now

Hmm, I think it will be hard to do because what I'm trying to do is to build a debian package and I'm using default debhelper rules.
This is my output http://pastebin.com/m6ade8454
Notice how it checks for ffmpegthumbnailer in the end, which doesn't happen on your machine. Don't have a clue why.

Try upgrading your ffmpegthumbnailer library to the latest version. The latest release fixed a memory leak.
I built ffmpegthumbnailer 2.0.6 and kffmpegthumbnailer 1.1.0 myself, but the problem persists.

In addition, it would be also great if the info window (when I hover a video file in Folderview) would display an even bigger preview, just like the images previews do it.
I can't change the sizes, kffmpegthumbnailer simply supplies the thumbnails in the dimensions requested by dolphin, ...
Hallo i added kffmpegthumbnailer into kde. I think that kde sc 4.5 will ship it. Thanks for your great work!
Is there anyway to get rid of the film strip border?
Remove line 32 in kffmpegthumbnailer.cpp and recompile
i installed it from a package manager but i guess i can try uninstalling it and compiling it
I had some trouble with it but reading the previous comments helped me trough it.
i have tried to install ffmpegthumbnailer via svn and i get it now trying installing kffpegthumbaniler i get http://pastebin.ca/1788042
Just keep using the old version, there is no reason to upgrade.
yes but... i mean the older version was compiling .. without problems is the new one bugged?
No you failed to install the ffmpegthumbnailer library properly. Just wait to install the new version untill ubuntu updates the ffmpegthumbnailer package.
