##Fixed point Opus on Debian
Debian/Raspbian currently doesn't provide a fixed point Opus build.
This results in very high cpu usage for audio decompression, especially on the Raspberry Pi.
Limelight Embedded can load another Opus build for you from the current working directory.
To compile Opus with fixed point support you have to execute the following commands:
wget http://downloads.xiph.org/releases/opus/opus-1.1.tar.gz
tar xf opus-1.1.tar.gz
cd opus-1.1
./configure --enable-fixed-point
make
Then copy libopus.so from opus-1.1/libs to the directory from which you start Limelight Embedded.
##Compile
* Install ant (Debian/Raspbian/Fedora/Pidora) or apache-ant (Archlinux)
