This Wireshark capture shows an excerpt of a VLC HEVC output RTP stream where sequence numbers continue to increment smoothly but timestamps are “set back”:
I’ve highlighted three (3) packets where this happens. What is the reason for this ? Is it some form of (re-) synchronization ? It doesn’t seem to be related to the associated MPEG audio, at least as far as I can see. Is this VLC-specific or happens in other video output stream providers ?
Fyi, my VLC version is 3.0.21 and this is the VLC output command I used:
:sout=#transcode{vcodec=hevc,acodec=mpga,ab=128,channels=2,samplerate=44100,scodec=none}:duplicate{dst=sap{dst=192.168.1.2,port=9875,name=raccoon_test},dst=rtp{dst=127.0.0.1,port=5004,name=raccoon_test},dst=display} :sout-all :sout-keep
