Coded bitstream unit structure.
A bitstream unit the smallest element of a bitstream which is meaningful on its own. For example, an H.264 NAL unit.
See the codec-specific header for the meaning of this for any particular codec.
| CodedBitstreamUnitType CodedBitstreamUnit::type |
Codec-specific type of this unit.

| uint8_t* CodedBitstreamUnit::data |
Pointer to the directly-parsable bitstream form of this unit.
May be NULL if the unit currently only exists in decomposed form.

| void* CodedBitstreamUnit::content |
Pointer to the decomposed form of this unit.
The type of this structure depends on both the codec and the type of this unit. May be NULL if the unit only exists in bitstream form.
