When making selections, AVPlayer treats the preferredLanguages as the paramount criterion and the preference for preferredMediaCharacteristics as secondary.

The objects in the preferredLanguages array are indicated using BCP 47 language identifiers or ISO 639-2/T language codes.

If no option with any of the preferredLanguages is available, a selection is made according to the default enabling and disabling of media options as stored in the asset.

The preferredMediaCharacteristics are used when selecting media for the AVPlayer.

For example, desirable characteristics of legible media may include AVMediaCharacteristicTranscribesSpokenDialogForAccessibility and AVMediaCharacteristicDescribesMusicAndSoundForAccessibility.

Similarly, desirable characteristics of audible media may include AVMediaCharacteristicDescribesVideoForAccessibility.

If no option is found that possesses all of the desired characteristics, the option that best matches the desired characteristics will be selected.
