--- Comment #23 from Nick <skywalker.nick at gmail.com> ---
I used wireshark to check whether there is pt-99 retransmission stream from
sender to receiver. I only discovered NACK before. However, when I modified the
rtpsession code and re-compiled and re-run it, I was able to see the pt-99
stream.

I just run the server-rtpaux/client-rtpaux to demonstrate the retransmission.

I debugged it, and noticed that several rtx options, like rtx-retry,
rtx-timeout, rtx-deadline, etc, are involved. I just use the default value
which is automatically determined by gstreamer.

I understand it is really strange. I will continue working on it.
