Data Fields
bool	z
	Z – the first OBU element of this packet is the continuation of an OBU fragment that started in the previous packet.
bool	y
	Y – the last OBU element of this packet is an OBU fragment that will continue in the next packet.
uint8_t	w
	W (2 bits) – count of OBU elements in this packet.

Field Documentation

n

bool SmolRTSP_Av1AggregationHeader::n

N – this packet is the first packet of a new coded video sequence.

RFC constraint: if N == 1 then Z must be 0.

w

uint8_t SmolRTSP_Av1AggregationHeader::w

W (2 bits) – count of OBU elements in this packet.

0 means each element is preceded by a LEB128 length field; 1, 2, or 3 means exactly that many elements and the last one omits its length field.
