# Class LowLatencyProfile

java.lang.Object
com.castlabs.android.player.LowLatencyProfile

public class LowLatencyProfile extends Object
Profile that groups all the relevant parameters related to low latency live streaming.

This profile can be applied to an existing Bundle or PlaybackState *before* passing it to `PlayerController.open(Bundle)`.

All the fields defined in this class will override the values from other configurations.

To get an instance use the `LowLatencyProfile.Builder`.
