  If you employ an AVAssetResourceLoader delegate that loads media data for playback, you should set the value of your AVPlayer’s automaticallyWaitsToMinimizeStalling property to NO. Allowing the value of automaticallyWaitsToMinimizeStalling to remain YES when an AVAssetResourceLoader delegate is used for the loading of media data can result in poor start-up times for playback and poor recovery from stalls, because the behaviors provided by AVPlayer when automaticallyWaitsToMinimizeStalling has a value of YES depend on predictions of the future availability of media data that that do not function as expected when data is loaded via a client-controlled means, using the AVAssetResourceLoader delegate interface.
 
  You can allow the value of automaticallyWaitsToMinimizeStalling to remain YES if you use an AVAssetResourceLoader delegate to manage content keys for FairPlay Streaming, to provide dynamically-generated master playlists for HTTP Live Streaming, or to respond to authentication challenges, but not to load media data for playback.

  @abstract Indicates the source audio channel layouts allowed by the receiver for spatialization.
  @discussion
    Spatialization uses psychoacoustic methods to create a more immersive audio rendering when the content is played on specialized headphones and speaker arrangements. When an AVPlayerItem's allowedAudioSpatializationFormats property is set to AVAudioSpatializationFormatMonoAndStereo the AVPlayer will attempt to spatialize content tagged with a stereo channel layout, two-channel content with no layout specified as well as mono. It is considered incorrect to render a binaural recording with spatialization. A binaural recording is captured using two carefully placed microphones at each ear where the intent, when played on headphones, is to reproduce a naturally occurring spatial effect. Content tagged with a binaural channel layout will ignore this property value. When an AVPlayerItem's allowedAudioSpatializationFormats property is set to AVAudioSpatializationFormatMultichannel the AVPlayer will attempt to spatialize any decodable multichannel layout. Setting this property to AVAudioSpatializationFormatMonoStereoAndMultichannel indicates that the sender allows the AVPlayer to spatialize any decodable mono, stereo or multichannel layout. This property is not observable. The default value for this property with video content is AVAudioSpatializationFormatMonoStereoAndMultichannel. Otherwise, audio only content default value is AVAudioSpatializationFormatMultichannel.
