Coded bitstream fragment structure, combining one or more units.
This is any sequence of units. It need not form some greater whole, though in many cases it will. For example, an H.264 access unit, which is composed of a sequence of H.264 NAL units.
| uint8_t* CodedBitstreamFragment::data |
Pointer to the bitstream form of this fragment.
May be NULL if the fragment only exists as component units.
