Last month we reported on a PS4 Remote Play open source client in development by thestr4ng3r, and today he released Chiaki... the first free and open source PS4 Remote Play client software for Android, Linux, macOS, Windows and potentially even more platforms! :love:

Download: Chiaki v2.1 (Latest Version) / Chiaki Github / Chiaki-Android.aab / Chiaki-Android.apk / Chiaki-Linux-x86_64.AppImage / Chiaki-macOS-x86_64.dmg / Chiaki-Windows-x86_64.zip / GIT / Chiaki Android APK / Chiaki AutoCompile Script / GIT / Chiaki4Deck (Latest Build) / GIT Fork via streetpea

From the README.md, to quote: 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)
  • Make the console send in higher Bitrate (if possible)
  • Touchpad support (Triggering the Touchpad Button is currently possible by pressing T on the keyboard)
  • 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:
Code:
mkdir build && cd build
cmake ..
make
Obtaining your PSN AccountID

Starting with PS4 7.0, it is necessary to use a so-called "AccountID" as opposed to the "Online-ID" for registration (streaming itself did not change). This ID seems to be a unique identifier for a PSN Account and it can be obtained from the PSN after logging in using OAuth. A Python 3 script which does this is provided in scripts/psn-account-id.py. Simply run it in a terminal and follow the instructions. Once you know your ID, write it down. You will likely never have to do this process again.

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.

Hey guys, Happy new year.. ps remote play (9.00 JB) works fine in same network, but when i tried to connect in different network doesn't work keep showing this error.

is it actually possible to use PS Remote Play for different Network in JB PS4 ? not sure if am wrong but for example Chiaki need HOST (public IP) to find your PS4, but how supposed PS Remote Play (different Network) find my PS4 if am not using PSN account in JB PS4 and using random account in PS Remote Play?

am i supposed to login using same PSN account i used in PS Remote Play in my JB PS4 ? if am not wrong but it's impossible to use PSN account in JB PS4, i hope someone explain to me.
 
Hi, my PS4 Remote Installer v3 does not work anymore, can someone upload the already installed folder ?

I can't use Chiaki because it has audio lag
