Fields

Name	Type	Description
chunkLength	b
headerLength	int
payloadLength	int	size of the mpeg data
mbz	uint8_t	Unused. Must be set to zero in current specification.
two	bool	Set to 1 when the MPEG-2 video-specific header extension follows this header.
temporalReference	uint16_t	The temporal reference of the current picture within the current GOP.
activeN	bool	Set to 1 when the following bit (N) is used to signal changes in the picture header information for MPEG-2 payloads.
newPictureHeader	bool	Used for MPEG-2 payloads when the previous bit (AN) is set to 1. Otherwise, it must be set to zero.
sequenceHeaderPresent	bool	Normally 0 and set to 1 at the occurrence of each MPEG sequence header.
beginningOfSlice	bool	Set when the start of the packet payload is a slice start code, or when a slice start code is preceded only by one or more of a Video_Sequence_Header, GOP_header and/or Picture_Header.
endOfSlice	bool	Set when the last byte of the payload is the end of an MPEG slice.
pictureType	uint8_t	picture type of the frame the data in this packet belongs to.
fbv	bool	full_pel_backward_vector
bfc	uint8_t	backward_f_code
ffv	bool	full_pel_forward_vector
ffc	uint8_t	forward_f_code currenrtly unused fields: int mzb; int two; int temporalReference; int activeN; int newPictureHeader; int sequenceHeaderPresent; int beginningOfSlice; int endOfSlice; int fbv; int bfc; int ffv; int ffc;
mutable	bool
complete	bool
correct	bool
properlyRepresented	bool
