Hi,
Try using this plugin -
http://rapidshare.com/files/16393248/enviviotv.exe.html
And read the following:
Unfortunately Microsoft has decided to not offer support for real MPEG4
content in their embedded mediaplayer. This means that Windows Media Player
is not able to playback these streams on its own. We have a plugin
available from EnvivioTV that enables MPEG4 playback in Windows Media
Player.
RealONE also supports MPEG4, but has adopted some of the standardized
extensions for its own use. Its therefore uncertain if the client software
will playback our streams with out problems. Fortunately the above mentioned
EnvivioTV plugin also works for Real.
The drawback with EnvivioTV is that it works best if the SDP files are named
M4E.
Download EnvivioTV media player plugin for Windows -
http://www.uninett.no/multimedia/programmer/enviviotv.exe
Or from here http://rapidshare.com/files/16393248/enviviotv.exe.html
There are several other clients available that claims to handle MPEG4, but
these are the ones we have larger or smaller experience with.
Test streams
Once you have installed your chosen media player software you should test
your capabilities for streaming MP4. The simplest test is to try to view a
small MPEG4 unicast file. Open rtsp://darwin.uninett.no/sample.mp4 in your
media player.
Again, if you are dependent on the EnvivioTV plugin you may be forced to
enter the URL as e-rtsp://darwin.uninett.no/sample.mp4 instead.
