I try to use mplayer via rtsp to a darwin streaming server. I get the following error:

Playing rtsp://localhost:554/sample_300kbit.mp4 Connected to server: localhost Stream not seekable! Initiated "video/MP4V-ES" RTP subsession Initiated "audio/MPEG4-GENERIC" RTP subsession Unknown MPlayer format code for MIME type "audio/MPEG4-GENERIC" FPS not specified in the header or invalid, use the -fps option.

You are using an old version of "MPlayer". Please upgrade to the "latest CVS snapshot" version of MPlayer, and try building again (after configuring with "--enable-live", of course; see <http://www.live.com/mplayer/>). Ross.
