Player flow diagram

To operate correctly player requires connectivity to 3 additional services:

API
Ad decisioning server (DS)
3rd party services for VAST events

During player initialisation player is checking if provided session is still valid by calling API:

Session verification

curl 'http://qa-lgi-api.frequency.com/api/2.0/auth/session' -H 'x-frequency-auth: bdd6c80b-5fb8-4957-b140-a0c26747e45b' -H 'x-frequency-deviceid: 58f67176-743f-d762' --compressed

Session response

{  
   "country":"PL",
   "user_agent":"Paw/3.1.7",
   "device_id":"58f67176-743f-d762",
   "token":{  
      "token_access":"bdd6c80b-5fb8-4957-b140-a0c26747e45b",
      "token_refresh":"0c6d9018-8f4a-483b-9e35-dd21f2715748",
      "roles":[  
         "ROLE_ANONYMOUS",
         "ROLE_USER"
      ]
   },
   "app_name":"telenet",
   "app_id":"6394703612760826080",
   "user_id":"6410435873178213705",
   "session_id":"035c2005-761a-4c85-a1f6-9e3640c743ea",
   "account_id":"6113878517855336672"
}

When session is valid player stores account_id for future DS calls and is ready to load video feed. This is done by executing one of the functions:

loadVideo
loadChannel
loadPlaylist

Example call looks like one below:

Load channel videos

curl 'http://qa-lgi-api.frequency.com/api/2.0/channels/6341811119618533518/videos' -H 'x-frequency-auth: bdd6c80b-5fb8-4957-b140-a0c26747e45b' -H 'x-frequency-deviceid: 58f67176-743f-d762' --compressed
