I configured mediatomb as follows:
CONFIGURATION SUMMARY ----
sqlite3 : yes
mysql : yes
libjs : yes
libmagic : yes
inotify : yes
libexif : yes
id3lib : disabled
taglib : yes
libmp4v2 : yes
ffmpeg : yes
ffmpegthumbnailer : yes
lastfmlib : yes
external transcoding : yes
curl : yes
YouTube : yes
libextractor : disabled
db-autocreate : yes
Enabling id3lib automatically disables libtag, so I assume enabling libextractor will disable another package.
