Hi All, 
I read about the RFC3984 for H.264, one of the type it can support is fragmentation Unit Mode(FU).
In FU mode, the packet must add FU indicator(1 byte) and FU Header (1 byte).

Indicator format

Header format

my question is why we need to include the NAL type twice in RTP packet of this (FU)mode?
