Really simple Ruby script to make a basic Live request to Zencoder with a few HLS outputs.

live_stream.rb

require 'rubygems'
require 'zencoder'

# Change these settings
s3_bucket         = ''
Zencoder.api_key  = ''

# Quick test to make sure the variables above are set...
if s3_bucket == '' || Zencoder.api_key == ''
  puts "It appears you haven't set your S3 bucket or Zencoder API key..."
  exit
end
