A Ruby library for easily getting metadata from Shoutcast-compatible audio streaming servers.
gem install shoutoutOr in your Gemfile:
gem "shoutout"require "shoutout"
# You can open a connection to the stream that will live for the duration of the block using `.open`:
Shoutout::Stream.open("http://82.201.100.5:8000/radio538") do |stream|
# Use `stream` as described below.
end
# If you want a little more control over opening and closing the connection, just use `.new`:
stream = Shoutout::Stream.new("http://82.201.100.5:8000/radio538")
# You can then explicitly open a connection to the stream.
# You're responsible for closing it using `#disconnect` when you're done.
stream.connect
# If you call any of the reader methods below without having opened a connection using `#connect`
# or `.open`, one will be opened and closed around reading the information implicitly.
# This is convenient if you're only looking for one piece of information, but it is of course
# very inefficient if you're going to do multiple reads.
# Stream info
stream.name # => "RADIO538"
stream.description # => "ARE YOU IN"
stream.genre # => "Various"
stream.notice # => nil in this case, but this could very well have a value for your stream
stream.content_type # => "audio/mpeg"
stream.bitrate # => 128
stream.public? # => true
stream.audio_info # => { :samplerate => 44100, :bitrate => 128, :channels => 2 }
# Current metadata
stream.metadata # => { "StreamTitle" => "Armin van Buuren - This Is What It Feels Like", "StreamUrl" => "http://www.radio538.nl" }
# The Metadata object is a Hash that has been extended with the following features:
stream.metadata[:stream_title] # => "Armin van Buuren - This Is What It Feels Like"
stream.metadata[:stream_url] # => "http://www.radio538.nl"
stream.metadata.now_playing # => "Armin van Buuren - This Is What It Feels Like"
stream.metadata.website # => "http://www.radio538.nl"
stream.metadata.artist # => "Armin van Buuren"
stream.metadata.song # => "This Is What It Feels Like"
# Conveniently, `#now_playing` and `#website` are also available on the stream object:
stream.now_playing # => "Armin van Buuren - This Is What It Feels Like"
stream.website # => "http://www.radio538.nl"
# For convenience, all of the reader methods above are also available as class methods:
Shoutout::Stream.now_playing("http://82.201.100.5:8000/radio538") # => "Armin van Buuren - This Is What It Feels Like"
# Just like the equivalent `Shoutout::Stream.new("http://82.201.100.5:8000/radio538").now_playing`,
# this will automatically open and close a connection around reading the information.
# You can be notified every time the metadata changes:
stream.metadata_change do |metadata|
puts "Now playing: #{metadata.song} by #{metadata.artist}"
# => Now playing: This Is What It Feels Like by Armin van Buuren
end
# Of course, this only works with an explicitly opened connection.
# If you're done setting up but want the program to keep listening for metadata, say so:
stream.listen
# Note that listening will only end when the connection is lost or the end of file is reached,
# so anything that comes after this call will only then be executed.
# This will generally be the last call in your program.
# If we don't want to wait around and listen, just let the program exit or disconnect explicitly:
stream.disconnectCheck out the examples/ folder for an example that I actually use myself.
