La libreria LibVLC consente, fra l'altro, di estrarre informazioni dai TAG dei file audio: MP3, OGG, WMA.
E' necessario avere installata nel proprio sistema e richiamare in Gambas la libreria dinamica condivisa: "libvlc.so.5.6.0"
Mostriamo un semplice esempio pratico:
Library "libvlc:5.6.0"

libvlc_meta_NowPlaying, libvlc_meta_Publisher, libvlc_meta_EncodedBy, libvlc_meta_ArtworkURL,
