The -rtsp-* switches didn't seem relevant.  Turns out they aren't
available at all unless mplayer is built with liveMedia.  So I
recompiled the mplayer port with option LIVEMEDIA.  And presto,
mplayer -rtsp-stream-over-tcp (to cope with NAT) now *plays* the
stream just fine.  However, -dumpstream errors out:
Cannot dump this stream - no file descriptor available.

I don't see how most of these switches are relevant.

Hmm, "openRTSP -f 25 -w 688 -h 384 -4 -d 30 -t <url>" now captures
something that mplayer can sort of play.  Tons of errors, though.

Oh well.  I'll pass for now and maybe revisit this topic in a year.
