Gamestream client for Raspberry Pi

#Limelight Embedded

Limelight is an open source implementation of NVIDIA's GameStream, as used by the NVIDIA Shield, but built for Linux/OSX/Windows.

Limelight Embedded allows you to stream your full collection of Steam games from your powerful Windows desktop to your embedded system, like Raspberry Pi, CuBox-i and Hummingboard.

For a demo see this video.

Limelight-common is the shared codebase between different implementations of Limelight

Limelight also has an Android implementation.

Limelight-pc also has an Linux (X)/OSX/Windows implementation.

##Features

• Streams Steam and all of your games from your PC to your embedded system.

##Installation

• Download GeForce Experience and install on your Windows PC
• Install oracle-java8-jdk (Raspbian) or download and install Oracle Java SE (ARM v6 Hard Float)
• Download the compiled jar from the GitHub releases page
• Install libopus0 (Debian/Raspbian) or opus (ArchLinux/Fedora/Pidora)
• Configure sound

##Requirements

• GFE compatible computer with GTX 600/700 series GPU (for the PC you're streaming from)
• High-end wireless router (802.11n dual-band recommended) or Wired network
• Geforce Experience 2.1.1 or higher

##Quick Start

• Ensure your machine and embedded system are on the same network
• Turn on Shield Streaming in the GFE settings
• Start Limelight Embedded with pair
• Accept the pairing confirmation on your PC
• Start Limelight Embedded with stream
• Play games!

##Usage Usage: java -jar limelight.jar [options] host

-bitrate <bitrate>Specify the bitrate in Kbps
-app <app> Name of app to stream
-nosops Don't allow GFE to modify game settings
-input <device> Use <device> as input. Can be used multiple times
(default uses all devices in /dev/input)

-audio <device> Use <device> as ALSA audio output device (default sysdefault)

Use ctrl-c to exit application

##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)
• Install audio libraries libopus-dev and libasound2-dev (Debian/Raspbian) or opus-devel and alsa-lib-devel (Fedora/Pidora) or opus and alsa-lib (Archlinux)
• Install Raspberry Pi development libraries libraspberrypi-dev (Debian/Raspbian) or raspberrypi-vc-libs-devel (Fedora/Pidora) or raspberrypi-firmware-tools (Archlinux)
• Set JAVA_HOME to your JDK installation directory for example export JAVA_HOME=/usr/lib/jvm/jdk-7-oracle-armhf
• Initialize the git submodules git submodule update --init
• Build using Ant ant
