 * @param streams The existing sample streams, which will be updated to reflect the provided

 * @param streamResetFlags Will be updated to indicate new sample streams, and sample streams that
 *     have been retained but with the requirement that the consuming renderer be reset.
 * @param positionUs The current playback position in microseconds.
 * @param forceReset If true then a reset is forced (i.e. a seek will be performed with in-buffer
 *     seeking disabled).
