Emit server daemon.
Dependencies:
- erlang (minimum R14)
- ffmpeg (with x264 and faac, version 0.7.1 highly recommended)
- mkvtoolnix required if you want mkv subtitles to work.
  It should be in your package management system.
  If not: http://www.bunkus.org/videotools/mkvtoolnix/downloads.html
- miniupnpc: http://miniupnp.free.fr/files/download.php?file=miniupnpc-1.6.tar.gz

NOTE ubuntu users:
- Erlang in default apt repository is ancient. Run "sh erlang.sh" and it will
install it manually or find a repository with an up to date erlang version.
- FFmpeg in apt is also useless (no x264 and no libfaac). Run "sh ffmpeg.sh".
It will build packages of latest ffmpeg with the most common codecs. It will
also remove any existing ffmpeg, x264 and libvpx.

Install to default /usr/local
sudo ./install

Install to /usr
sudo ./install /usr


Once installed edit file:
/etc/emit.cfg
emit.cfg is a json file.
- encdir is where emit will put encoded files. This should be its own directory.
- dirs is a list of directories to share (encdir will be shared as well).
- port is 1554 TCP and 2000-2006 UDP by default. You can change it to X
   then it will be X TCP and X to X+6 UDP

Config example:
{
"port" : 3000,
"dirs" : [
	  "/home/user/videos1",
	  "/home/user/videos2"
	 ],
"webacc" : "true",
"password" : "mypass",
"encdir" : "/home/user/encode_dir"
}


Running:
- Start server
emit -s

- Start as daemon
emit -d

- Stop server
emit stop

- Pin of server for web access - server has to be running
emit pin
