DefaultDashChunkSource

public DefaultDashChunkSource(com.google.android.exoplayer2.upstream.LoaderErrorThrower manifestLoaderErrorThrower,
                              DashManifest manifest,
                              int periodIndex,
                              int adaptationSetIndex,
                              com.google.android.exoplayer2.trackselection.TrackSelection trackSelection,
                              com.google.android.exoplayer2.upstream.DataSource dataSource,
                              long elapsedRealtimeOffsetMs,
                              int maxSegmentsPerLoad,
                              boolean enableEventMessageTrack,
                              boolean enableCea608Track)

Parameters:

manifestLoaderErrorThrower - Throws errors affecting loading of manifests.

manifest - The initial manifest.

periodIndex - The index of the period in the manifest.

adaptationSetIndex - The index of the adaptation set in the period.

trackSelection - The track selection.

dataSource - A DataSource suitable for loading the media data.

elapsedRealtimeOffsetMs - If known, an estimate of the instantaneous difference between server-side unix time and SystemClock.elapsedRealtime() in milliseconds, specified as the server's unix time minus the local elapsed time. If unknown, set to 0.

maxSegmentsPerLoad - The maximum number of segments to combine into a single request. Note that segments will only be combined if their Uris are the same and if their data ranges are adjacent.

enableEventMessageTrack - Whether the chunks generated by the source may output an event message track.

enableCea608Track - Whether the chunks generated by the source may output a CEA-608 track.
