 * @param segmentBaseHolder The segment holder.
 * @param playlistUrl The url of the playlist from which this chunk was obtained.
 * @param muxedCaptionFormats List of muxed caption {@link Format}s. Null if no closed caption
 *     information is available in the multivariant playlist.
 * @param trackSelectionReason See {@link #trackSelectionReason}.
 * @param trackSelectionData See {@link #trackSelectionData}.
 * @param isMasterTimestampSource True if the chunk can initialize the timestamp adjuster.
 * @param timestampAdjusterProvider The provider from which to obtain the {@link
