# api: streamtuner2
# title: Shoutcast.com
# description: Primary list of shoutcast servers (now managed by radionomy).
# type: channel
# category: radio
# priority: default
# version: 1.4
# version: 1.5
# depends: pq, re, http
# author: Mario
# original: Jean-Yves Lefort
#
# Shoutcast is a server software for audio streaming. It automatically spools
# station information on shoutcast.com
# It has been aquired by Radionomy in 2014, since then significant changes
# took place. The former YP got deprecated, now seemingly undeprecated.
#
#   http://wiki.winamp.com/wiki/SHOUTcast_Radio_Directory_API 
#
# But neither their Wiki nor Bulletin Board provide concrete information on
# the eligibility of open source desktop apps for an authhash.
#
# Therefore we'll be retrieving stuff from the homepage still. The new
# interface conveniently uses JSON already, so let's use that:
#
#   POST http://www.shoutcast.com/Home/BrowseByGenre {genreid: 9}
#   POST http://www.shoutcast.com/Home/BrowseByGenre {genrename: Pop}
#
# We do need a catmap now too, but that's easy to aquire and will be kept
# within the cache dirs.
