Public struct PPS_t    
Public struct profile_tier_level_t    
Public struct scaling_list_data_t    
Public struct SEI_t    
Public struct SEI_t SEI can transmit arbitrary data so we probably want something less rigid for this.

Enums

  Type Name Description
Public enum EAV1Profile    
Public enum EH264AdaptiveTransformMode    
Public enum EH264EntropyCodingMode    
Public enum EH264PacketizationMode Packetization modes are defined in RFC 6184 section 6 Due to the structure containing this being initialized with zeroes in some places, and mode 1 being default, mode 1 needs to have the value zero.  
Public enum UEnum EH264Profile Easy to understand user facing profiles from the T-Rec-H.264-201304 spec there is another enum in CodecUtilsH264 that aligns the profiles with PIC and constraints however users are not expected to understand those ones.  
Public enum EH265Profile Easy to understand user facing profiles from the T-Rec-H.264-201304 spec there is another enum in CodecUtilsH265 that aligns the profiles with PIC and constraints however users are not expected to understand those ones.
