## Discussion

Discussion Criteria will be applied to an AVPlayerItem instance when: It is made ready to play. Specific media selections are made by the AVPlayerItem instance using the method select(_:in:) in a different group. The automatic choice in one group may be influenced by a specific selection in another group. Underlying system preferences change, e.g. system language, accessibility captions. Specific selections made by the AVPlayerItem instance using the method select(_:in:) method within any group will override automatic selection in that group until the player item receives a selectMediaOptionAutomatically(in:) message.
