 // TODO: Existing names used for the different NAL unit types can be altered to better reflect the names in the spec.
 //       However, the names in the spec are not yet stable at this point. Once the names are stable, a cleanup
 //       effort can be done without use of macros to alter the names used to indicate the different NAL unit types.
