In general, the PTS and DTS come from the demuxer (in this case RTP), then
can be mangled by the packetizer, the decoder, filters and output, etc. I
don't know H.264 specifically but my educated guess is that the PTS comes
from the RTP timestamp, and the DTS is inferred by the packetizer since RTP
does not provide any DTS.
