This is a quite old version. I don't know if RTMP support was as good
back then as it is now.

2.4.x is current. please try to get hold of that, or use latest git if
you build your own.

The way you're doing it is not optimal.
a) For dumping streams to disk, "mplayer -dumpstream" is the
   recommended path. :-)
b) You're re-encoding. That may or may not be your intention. To retain
   the original quality, use "-c copy".

Actually, answer b) may help you even with your old ffmpeg version.
