 M3u8::Writer is the class that handles generating the playlist output.
 
 Alternatively you can set codecs rather than having it generated automatically:

 item = M3u8::PlaylistItem.new options

 Just get the codec string for custom use:
 ```ruby
 options = { profile: 'baseline', level: 3.0, audio_codec: 'aac-lc' }
