/**
 * An AccessUnit is a list of one or more NAL units, according to the
 * working draft.  All NAL units within the object belong to the same
 * access unit.
 *
 * NALUnits held in the AccessUnit list are in EBSP format.  Attempting
 * to insert an OutputNALUnit into the access unit will automatically cause
 * the nalunit to have its headers written and anti-emulation performed.
 *
 * The AccessUnit owns all pointers stored within.  Destroying the
 * AccessUnit will delete all contained objects.
