public class DecodingTimeToSampleBox
This box contains a compact version of a table that allows indexing from
decoding time to sample number. Other tables give sample sizes and pointers,
from the sample number. Each entry in the table gives the number of
consecutive samples with the same time delta, and the delta of those samples.
By adding the deltas a complete time-to-sample map may be built.
The Decoding Time to Sample Box contains decode time delta's:
DT(n+1) = DT(n) + STTS(n)
where STTS(n) is the (uncompressed) table entry for sample n.
The sample entries are ordered by decoding time stamps; therefore the deltas
are all non-negative.
The DT axis has a zero origin; DT(i) = SUM(for j=0 to i-1 of delta(j)), and
the sum of all deltas gives the length of the media in the track (not mapped
to the overall timescale, and not considering any edit list).
The Edit List Box provides the initial CT value if it is non-empty
