Internet radio browser GUI for music/video streams from various directory services.

⌈⌋ branch:  streamtuner2


Check-in [f9c725e90b]

Overview
Comment:Adapt Xiph plugin for BETA/dir-test.xoph.org rollout. It's fairly terrible: homepages gone, bitrate unavailable, case-sensitive category segregration. On the upside: direct streaming server urls.

The 'cache' mode is likely broken soon, since the experimental JSON API is gone.

For now using `.title()` on /genre/{} search. Adapted guess_format to recognize AAC. Subtitle is used in lieu of On Air: text for playing=

# The ICEcast server is an open alternative to SHOUTcast.
#
# It also provides a directory listing of known internet
# radio stations; only a handful of them using Ogg though.
# The category list is hardwired in this plugin. And there
# are three station fetching modes now:
#
#  → "JSON cache" retrieves a refurbished JSON station list,
#    both sliceable genres and searchable.
#
#  → "Clunky XML" fetches the olden YP.XML, which is really
#    slow, then slices out genres. No search.
#
#  → While the secret "buffy" mode keeps the XML blob in memory.
#
#  → "Forbidden Fruits" extracts from dir.xiph.org HTML pages,
#    with homepages and listener/max infos available. Also
#    enables live server searching.





#
# The previous bitrate filter is now a separate plugin, but
# available for all channels.
