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.

Constructor Details

LowLatencyProfile

public LowLatencyProfile()

Create a new low latency profile with the default params

LowLatencyProfile

public LowLatencyProfile(CustomUtcTimingElement customUtcTimingElement,
 int liveEdgeLatencyMs,
 int hlsLiveTailSegmentIndex,
 float hlsPlaylistUpdateTargetDurationCoefficient,
 boolean hlsForcePlaylistUpdateTargetDuration,
 int minPlaybackStartMs,
 int minRebufferStartMs)

Create a low latency profile

Parameters:

customUtcTimingElement - Custom UTCTiming element to use

liveEdgeLatencyMs - Number of milliseconds that the playback should lag behind the live edge

hlsLiveTailSegmentIndex - The HLS live tail segment index

hlsPlaylistUpdateTargetDurationCoefficient - The target duration coefficient for playlist update interval.

hlsForcePlaylistUpdateTargetDuration - Whether to force the target duration coefficient when defining the playlist update interval

minPlaybackStartMs - The minimum duration of data that must be buffered for playback to start or resume following a user action such as a seek

minRebufferStartMs - The minimum duration of data that must be buffered for playback to resume after a player invoked rebuffer
