mplayer - no picture

  • Setup 313 elphel camera, running viewer on
    Camera contains elphel_6.2.15.  I down loaded ElphStreamer
    trying   ./ElphStreamer -w work? Do I need to move to 6.2.16?
    Things seem to start ok

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

    Any suggestions?

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

      ./mplayer elphel:// ...

      After you may try multicast
      May be your routers not translated multicast?
      Try ping -  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
      (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 doesn't work), so you need to add this net to your system routing table.
