-/**
- * Each sample of a track may be associated to (zero or) one of a number of sample group descriptions, each of
- * which defines a record of rate-share information. Typically the same rate-share information applies to many
- * consecutive samples and it may therefore be enough to define two or three sample group descriptions that
- * can be used at different time intervals.
- * <p/>
- * The grouping type 'rash' (short for rate share) is defined as the grouping criterion for rate share information.
- * Zero or one sample-to-group box ('sbgp') for the grouping type 'rash' can be contained in the sample
- * table box ('stbl') of a track. It shall reside in a hint track, if a hint track is used, otherwise in a media track.
- * <p/>
- * Target rate share may be specified for several operation points that are defined in terms of the total available
- * bitrate, i.e., the bitrate that should be shared. If only one operation point is defined, the target rate share
- * applies to all available bitrates. If several operation points are defined, then each operation point specifies a
- * target rate share. Target rate share values specified for the first and the last operation points also specify the
- * target rate share values at lower and higher available bitrates, respectively. The target rate share between two
- * operation points is specified to be in the range between the target rate shares of those operation points. One
- * possibility is to estimate with linear interpolation.
