Specific Information

• Both current playback queue and originally ordered playback queue is overwritten when this method is called and they will both be the same after this call independent of the playback queue mode currently active.
• For more details about individual parameters in beneath the items structure see Content Access Protocol findItems method.
• The type attribute can have the following values:
  • stream - Indicates a continuous stream, when such track is reached the player will continue to play it forever and never automatically move to the next track in the playback queue.
  • track - Indicates a track with a limited length, when it reaches its end the player will move on to the next track in the playback queue.
• The intermediate flag in the streamingRef entries is a special indication which is used to indicate to the player that it have to provide the ickStream device access token in the header of the request. The stream will URL will be redirected to the real stream when accessed. The real stream is typically temporary and won’t be valid long unless you start playing it so the player need to repeat the procedure every time the stream is played if intermediate is true. So when accessing a streaming reference with intermediate=true you always have to provide an Authorization header in same way as for other requests. This is not required for streaming references without intermediate flag set.

Response:

    "id": < The request identity >,
    "result": {
        "result": <true if tracks were successfully added >
        "playbackQueuePos": < Position of currently playing track within the playback queue >
    }
}

Specific Information

• If a streamingRefs url attribute is a service: URI, the player is responsible to use the getServiceInformation method to get the real the mapping to the real streaming url from the Content Access Protocol implementation of the content service.
