RTP is encapsulated in UDP. If you send an RTP stream to the GNU Radio
UDP block, you will get an RTP stream.
VLC is just a suggestion. It can send RTP containing Opus.

Well RTP provides important functionality when streaming over the
internet. Especially time stamping and sequence numbering which allows
to reassemble out of order data (UDP provides no such guarantee) and
adjustment for clock drift which, among other things, allows you to
keep the receiver buffer smaller for "real time" tuning.
RTP also provides a "telemetry" channel over RTCP for network statistics.
Not sure why you assume I will use VLC?
Of course if you are just streaming over a LAN raw UDP might be ok
since the risk of out of order packets is essentially zero.

RTP runs over UDP. Why would you need a block? Just let VLC do all the dirty
work.

Hi all,
Is there an RTP (real time protocol) streaming block? I know about the
UDP block but I want RTP/RTCP.
If not I will start writing one... Just don't want to start a new
project if there already is one.
Also, what happened to Opus in the gr-vocoder? Thinking about writing
an opus block as well.
The goal is streaming opus encoding audio from gnuradio from remote
locations.
