#
# Multimedia interface for starting audio players, recording app,
# or web browser (listed as "url/http" association in players).
#
# Each channel plugin has a .listtype which describes the linked
# audio playlist format. It's audio/x-scpls mostly, seldomly m3u,
# but sometimes url/direct if the entry[url] directly leads to the
# streaming server.
#
# As fallback there is a regex which just looks for URLs in the
# given resource (works for m3u/pls/xspf/asx/...).
