##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)
