Phew...
<div>1/ The interval between two successive "OPTIONS" commands
will almost never exceed the "timeout=" parameter that the
server reported. (A future release of the software will ensure
that it *never* exceeds this - because the interval will be
randomly chosen from "[delayMax/2,delayMax-1)" instead of the
current "[delayMax/2,delayMax)".)</div>

I made a similar change for the delayMax, but instead subtracted 10,
because I would see latency when I was logging OPTION commands. I
have a extremely busy WIFI network for testing. <br>
Thanks for that change as it is along the lines I was think and
confirms what I was seeing.<br>

<div>2/ In any case, this shouldn't matter, because - as I've said
AD NAUSEAM - the proxy server will send RTCP "RR" packets far
more frequently than this, and standards-compliant (i.e.,
correctly implemented) server will use these as an indication
that the proxy server is still alive.</div>
<div>3/ Should the camera "time out the shutdown the session" -
for any reason - then the subsequent "OPTIONS" command from the
proxy server will fail, and the proxy server will then reopen
the connection. That's the PRIMARY PURPOSE of the periodic
"OPTIONS" commands: To check whether the server still thinks
that the session is alive.</div>
