    Camera contains elphel_6.2.15.  I down loaded ElphStreamer
    trying   ./ElphStreamer -w work? Do I need to move to 6.2.16?

    I get the font error messages and I am not sure
    what to put in the *desc file.

    Any suggestions?

    thanks,

      First step -try use unicast
      On Elphel streamer you can set address of host, where running mplayer
      And mplayer start with parameters

      ./mplayer elphel://192.168.1.11:20000 ...

      After you may try multicast
      May be your routers not translated multicast?
      Try ping 224.0.0.1 -  you can receive reply from camera.  If no - configure yuors routers(switches)
      Second way - you can use mrouted on hosts

      You can put any *.ttf   font (rename it) into
      /root/.mplayer/subfont.ttf
      (or in .mplayer/ in home directory users)
      for support subtitles

       
    • I think that problem is not fonts. It's just a last message seen.. After that message mplayer looks for multicast net and cannot find it (ping 224.0.0.1 doesn't work), so you need to add this net to your system routing table.
