I've never argued with putting 7 TS packets into 1 frame, since this is
indeed a lot better. I'm just saying, that the addition of 12-byte RTP header
Multimedia delivery over raw UDP builds on incorrect assumptions, that it
expects the IP network to deliver packets in the correct order and not
duplicated. This was NEVER the case with IP networks - which means
multimedia delivery over raw UDP is flawed in basic principles. That's why
everyone in the VoIP industry uses RTP and not raw UDP.
Believe me, after 11+ years of experience with designing, building and
operating of IP networks I had enough chances to prove this.

Sure, I fully agree. I was just trying to say, that the preferred, mainstream
option should be the one which really works (i.e. RTP) and not the one which
emerged in the very early days of "the streaming server industry", which is
seriously flawed and which has been proved not to work in many cases.
And yes, I agree we should stop this thread now.
