I just took a closer look at the API and I will try creating a media
instance that will be used for the life of my application and use
libvlc_media_instance_set_media_descriptor for each new file I play. That
way I won't release the media instance from inside my event. This seems like
a much better idea. I'll let you know how it turns out.
