RPI-GPU-rdpClient

Video on youtube: http://youtu.be/3HJuHhiXxuE

Hardware accelerated raspberry pi client for windows PC. It is more a proof-of-concept to show that OpenMAX can be used as a RDP viewer rather than a finished product. There is no authentication, use at your own risk.

It uses a NVIDIA graphic card to encode H.264 video, and OpenMAX to display the video. It can achieve 1080P 60FPS RDP on a RPI with a relatively low latency of ~200ms on two monitors. When the GPU is not accessible on the server, it falls back to CPU encoding. It uses DXGI for accelerated desktop capture in Windows 8 It can work in a Virtual machine in order to be a true thin client.

To compile the client on the Raspberry PI

It needs the following packages. I started on a clean version of the Raspberian OS.

sudo apt-get install cmake
sudo apt-get install libboost-thread-dev libboost-system-dev
sudo apt-get install libx11-dev

To compile ilclient:

cd /opt/vc/src/hello_pi
sudo ./rebuild.sh

To compile the RDP client:

git clone https://github.com/jean343/RPI-GPU-rdpClient.git
cd RPI-GPU-rdpClient/RPI-Client
mkdir build && cd build/
cmake ..
make

To run the client

./client

###To compile the server in windows###

• Install CMAKE and Boost
  • http://www.cmake.org/install/
  • http://www.boost.org/users/download/
• Compile boost or download the binaries
• In cmake under the Server folder
  • Set BOOST_ROOT to the root of the Boost folder "C:/boost_1_51_0" on my machine
• Build, I used Visual Studio
• Optional, FFMPEG for a CPU fallback if the graphic card is unavailable
  • Download FFMPEG from http://ffmpeg.zeranoe.com/builds/, need the dev and shared
    • Set FFMPEG_ROOT to the root of FFMPEG dev folder
    • Add the bin folder of the shared zip to your path, or copy the DLLs

To run the server

./server monitor 0 port 8080

Want to be part of the project? Great! All are welcome! We will get there quicker together :) Whether you find a bug, have a great feature request feel free to get in touch.

Known issues and limitations

• There is no audio
• There is no authentication, use only in a local LAN or under a VPN.
• The software falls back to CPU encoding in a Virtual Machine, it is fast as it uses the x264 superfast preset, but the H.264 quality is reduced.

NOTES

From https://github.com/Hexxeh/rpi-update, update your pi:

sudo rpi-update

Update software:

sudo apt-get update && sudo apt-get upgrade
