1) When assembling FU-A packets, it also needs to check
RTP sequence number so that we can know how to
assemble fragmented FU-A packets at the right memory location.
If it's normal, sequence number should be incremental by 1.
2) SPS and PPS of H264 can be retrieved from the following line of SDP file
using BASE64 decoding.
a=fmtp:96 packetization-mode=1; profile-level-id=42e00d; sprop-parameter-sets=Z0LgDdoFB+wEQAAAAwBAAK/IGKAB6IAPRb3vg+OFVA==,aM41IA==
3) The order of H264 NALUs should be
SPS (NAL type = 0x7) -> PPS (0x8) , I-frame (0x5), P-frame(0x1)....
