    26. 

  26. <p class="description"><p>The <em>Sample To Chunk Box</em> table can be used to find the chunk that  contains a sample, its position, and the associated sample description.</p><p>The table is compactly coded. Each entry gives the index of the first chunk  of a run of chunks with the same characteristics. By subtracting one entry  here from the previous one, you can compute how many chunks are in this run.  You can convert this to a sample count by multiplying by the appropriate  samplesPerChunk.</p></p>
