Sony recently upgraded the system software on the PlayStation 4 which broke compatibility with the open source Remote Play client Chiaki. The developer acted quickly and a new release is up.

This is the software we tested out recently and came away pretty impressed with it. Allowing you to stream games from a PlayStation 4 to a Linux desktop, seriously handy stuff since Sony don't support it on Linux officially.

Here's what's new in Chiaki 1.0.4:

  • Add Regist with Np-AccountId (Fix #51)
  • Bump RP-Version to 9.0 for Session and Ctrl, #51
  • Add more logging to Ctrl, for #36
  • Add Audio Buffer Size Setting
  • Send one Feedback History Packet per Event (#41)
  • Use Qt MacExtras on macOS
  • Refactor Opus Decoding
  • Make YUV/RGB conversion more accurate

The way you actually link up Chiaki with your PlayStation 4 has changed now too. The PS4 7.0 firmware moved over to requiring an AccountID, so the Chiaki developer made a Python script to get for you. Run it in terminal with the self explanatory options it presents and it will get you what you need. You just need to copy and open a URL, login with your Sony account and then copy the redirect page URL into the script and it will then provide you with your AccountID. A little extra hoop required but still incredibly easy to do.

As a reminder, it also needs a PIN code from your PS4 console. To get that, load up your PS4 and go into Settings -> Remote Play Connection Settings -> Add Device and then you will be able to get the PIN that Chiaki needs.

Once you have both codes, enter them into Chiaki and then your console will be registered and you should never have to do any of that again. Here's another video to just to show it off quickly with the latest PS4 firmware and the latest Chiaki:

Compared with the previous version, performance actually seems better too it was more playable this time around. Love seeing open source projects like this filling another gap on Linux. Hope to see this continue expanding and improving.

See more about it on GitHub.

I updated chiaki this morning and so far it's smooth for me. But under macOS Catalina I get controller input lag with both dualshock 4 and xbox one controllers. I do not get any such lag with the Linux appimage. I used the perl script and followed the directions to get my new fangled 7.0 user id. All's good and smooth playing so far on Fedora 31. I'd love to have a Chromebook build so I can sit in bed and play.

This is really nice. Now my PS4 is a lot less annoying to use. To remove the final annoyance I think I will put my PS4 next to my servers because god damn is it noisy.

I'm a new owner of a PS4 slim since three months and have never really played PS4 before. But lately I just realized, how quiet the slim is compared to the old and pro models. I was shocked how loud the fan of these models is. For me it would be unacceptable in the living room...

On topic: I really appreciate Chiaki and used it already to play RDR successfully on my Linux desktop. However, I wish it would be possible to use 1080p on non-pro models, but I guess this is a Sony restriction

I have the original one, and it's ridiculously loud when you're actually playing a graphics intensive game. At least it's quiet compared to the servers
Spoiler, click me
liam, why are my emojis turning into question marks

My god, are you saying I can play Bloodborne from the comfort of my desk? Sold

I legit avoid playing PS4 games just because I don't feel like going in the living room; it belongs to the cats, and I don't like to intrude :B

Edit: Only thing I need now is to be able to play bloodborne at 60+ Fps o3o
