Tumbler has since version 0.1.27 a configuration file to control the priority and locations, file sizes a plugin is used for: tumbler.rc.
To override the default configuration, located in one of the xdg directories on your system, you can copy the rc-file to your
mkdir -p $XDG_CONFIG_HOME/tumbler cp /etc/xdg/tumbler/tumbler.rc $XDG_CONFIG_HOME/tumbler/
Each group in the plugin is responsible for the settings of a particular thumbnail provides plugin. The following keys can be used to adjust a plugin:
By the default the cover thumbnailer is disabled. The reason is that it sends information (movie title extracted from the filename) to online services to retrieve a poster. This information is normally harmless, but it is private, so therefore it's not enabled by default.
In order to use the cover thumbnailer you need to copy the tumbler.rc file to your home directory like described above and set the
Disabled key to
false. It is also advised to set the Locations path to the directory where you store your movies.
[CoverThumbnailer] Disabled=false Priority=3 Locations=~/movies MaxFileSize=0 #APIKey=your-api-key-from-themoviedb.org
The movie thumbnailer supports 2 different movie API's. By default the The Open Movie Database API is used. At your choice you can also use The Movie DB, but this site requires an API key, which you have to request or uh… search.
Advantage of the latter is that their database has better support for internationalized movie names.
After creating the rc file, it is best if you log-off and on again to restart Thunar and Tumbler, because both applications cache the mime-type combinations.
