Chiaki

Disclaimer: This project is not endorsed or certified by Sony Interactive Entertainment LLC.

Chiaki is a Free and Open Source Software Client for PlayStation 4 Remote Play for Linux, macOS, Windows and potentially even more platforms.

Features

Everything necessary for a full streaming session, including the initial registration and wakeup of the console, is supported. The following features however are yet to be implemented:

Congestion Control
H264 Error Concealment (FEC and active error recovery however are implemented)
Touchpad support (Triggering the Touchpad Button is currently possible by pressing T on the keyboard)
Rumble
Configurable Keybindings

Downloading a Release

Builds are provided for Linux, macOS and Windows. You can find them here.

Linux: The provided file is an AppImage. Simply make it executable (chmod +x <file>.AppImage) and run it.
macOS: Drag the application from the .dmg into your Applications folder.
Windows: Extract the .zip file and execute chiaki.exe.

Building from Source

Dependencies are CMake, Qt 5 with QtMultimedia, QtOpenGL and QtSvg, FFMPEG (libavcodec with H264 is enough), libopus, OpenSSL 1.1, protoc and the protobuf Python library (only used during compilation for Nanopb). Then, Chiaki builds just like any other CMake project:

git submodule update --init
mkdir build && cd build
cmake ..
make

Acknowledgements

This project has only been made possible because of the following Open Source projects: radare2, Cutter, Frida and x64dbg.

Also thanks to delroth for analyzing the registration and wakeup protocol, as well as a huge thank you to FioraAeterna for giving me some extremely helpful information about FEC and error correction.
