Configuration to Chromecast

  • Hi everyone,

    I'm sorry my english.

    After a lot of days trying see my movies with subtitles I finally can put Chromecast to work using mediatomb (using Avia). Please use it and help me to improve it.

    I use Ubuntu 13.10.

    To work yo need install (compile) the last version of FFMPEG. (https://trac.ffmpeg.org/wiki/UbuntuCompilationGuide)

    Create the file "mediatomb-ceac13-transcoder" in /usr/local/bin/ and put this content:
