Schatkamer Player for PS5

An experimental, personal web app for a jailbroken PS5 that browses, searches and plays programmes from the Schatkamer archive of Beeld & Geluid on the console, with picture, sound and the site's PlayReady DRM.

Terms of use. Schatkamer's published terms prohibit automated access and third-party interfaces, even for personal use. This project is a technical experiment; check with the service provider before relying on it.

What it is

One payload, schatkamer-app.elf, and one home-screen app, Schatkamer Player.

• The payload installs the app, then runs a small server on 127.0.0.1:48731. The server serves the UI, reads the site's search and browse data, signs a programme's stream when you pick it, and relays the CDN to the player with certificate-verified curl (src/app.c). It never decrypts media or touches licences: the player talks to the site's PlayReady service itself.
• The app is a web app in the console's media web-app context, the only place the console's DRM works for this site. Its page (src/webui.html) is the whole interface: featured rows, search with recent searches, lists with sorting and paging, details, and a player (Shaka Player 4) with a controls bar.

Requirements

• A PS5 running a jailbreak with an ELF loader on port 9021 (the payload installs the app itself; nothing else is mounted).
• Windows with WSL (Ubuntu) or Linux to build. No hardware tools beyond that.

Build

sudo apt install clang lld llvm llvm-dev make pkg-config git wget python3
bash build.sh

build.sh clones the pinned PS5 payload SDK, fetches the pinned PacBrew libraries (about 350 MB, checksum verified), and builds schatkamer-app.elf. GitHub Actions does the same on every push (.github/workflows/build.yml) and keeps the payload as an artifact.

Install and run

1. Send schatkamer-app.elf to the ELF loader, for example with nc:

   nc -w 5 <ps5-ip> 9021 < schatkamer-app.elf
   

   It installs Schatkamer Player on the home screen and starts the server.

2. Open Schatkamer Player.

The server stops when the console restarts or sleeps deeply: send the payload again (or autoload it with your payload manager) before opening the app.

The start URL

The console's web-app launcher only accepts an https start URL with a certificate it trusts; local addresses, file: URLs and self-signed certificates were all refused. launcher/param.json therefore points at a short link that redirects to http://localhost:48731/. Make your own redirect that targets that address (a URL shortener or any HTTPS page you control) and put it in webAppUri, then rebuild.

Controls

Button	Home	Search	List	Player
D-pad	Move	Move	Move	Left/Right 10 s, Up/Down 1 min
Cross	Open	Open the keyboard	Open	Play / pause
Triangle	Search	Space
Square		Delete / forget a recent search	Sort
R2		Search
L1 / R1	Jump along a shelf		Jump in the list
Circle		Back	Back	Back

The console's keyboard commits the word on the first R2; the page then searches.
