I got a AVTP packet data from vehicle`s side mirror camera. protocol is H264(AKA codec) and transported by FU-A. enter image description here
I want to decode these data to stream. Before, I refered rtp_h264_extractor.lua, but it does not work well.
My question is how to combine my data for decoding.
First, there are SPS, PPS, I-Slice in wireshark. but, no start code(\x00 \x00 \x00 \x01). Just type code(\x67, \x68, \x65). enter image description here \x00 \x00 \x00 \x00 is h264 timestamp, not start code. Is it ok just add start code by myself?
Second, Unkown(not indicate I-slice) packets have start code + I-slice type code.
Third, SPS and PPS are separated very far. PPS is next to SPS, but my data`s SPS packet number is 10, PPS is 122. I-Slice start packet and I-Slice end packet is located between SPS and PPS. Unkown I-Slice packets(Second) are located between SPS and PPS too.
Let me know Some tips for combine my data.
Thanks a lot.
I tried parsing SPS, PPS, I-Slice in wireshark by scapy, and using ffmpeg. But does not work.
Under tries are not work too.
