[MPlayer-users] Compiling in LIVE.COM Streaming Media into mplayer.

[Russell McOrmond]

  I built RPM with mplayer with the LIVE.COM support for RTSP.  I started
with the .src.rpm provided at
http://luna.cs.ccsu.edu/dominik/mplayer/rebuilding.html , and then patched
the spec file to add in http://www.live.com/liveMedia/

  I received an error when compiling, and tried the patch suggested at:
http://zebra.fh-weingarten.de/~maxi/html/mplayer-dev-eng/2004-07/msg00347.html

  Unfortunately it did not work as I had hoped.  There is a streaming
provider http://www.akamai.com/ which is streaming the audio for Canada's
public broadcaster http://www.cbc.ca/listen/ . Currently they are
streaming using Microsoft's MMS protocol, and I had hoped to find out if
the same service supported IETF standard RTSP.

One of the audio streams (Ottawa, where I live) which works well is at:
mplayer mms://a907.l961736906.c9617.g.lm.akamaistream.net/D/907/9617/v0001/reflector:36906

so I tried:
mplayer rtsp://a907.l961736906.c9617.g.lm.akamaistream.net/D/907/9617/v0001/reflector:36906


 Unfortunately mplayer output:

  Any thoughts appreciated.  Does this service just not support RTSP, or 
is this an issue with mplayer or the LIVE.com libraries?


  Details of the RPM (I can post this if anyone wanted it), built on
Fedora Core 1.  This may be useful for Dominik Mierzejewski to incorporate 
into his RPM builds of mplayer.
