Done: as expected this hasn't made any difference, like

explicitly setting audio sample rate. I know nothing about your network
configuration, but I have to provide -rtsp-stream-over-tcp option for
MPlayer/MEncoder to be able to play the stream. If you don't need this
option, it could be the explanation for the FFmpeg failure on my system,
if FFmpeg doesn't use rtsp over tcp by default (does it support rtsp
over tcp at all?).
