PS5 AirPlay

An AirPlay screen-mirroring receiver for jailbroken PS5 consoles. Mirror an iPhone, iPad or Mac to the TV the console is plugged into, with sound, from the home screen or on top of a game.

It runs as a payload: no package to install, no firmware to modify.

What it does

Video	H.264 (Baseline, Main, High), up to 1920×1080 at 60 fps. Decoded in software with FFmpeg.
Audio	AAC-ELD, 44.1 kHz stereo (what iOS and macOS send while mirroring).
Output	1920×1080. The picture keeps its proportions; a phone held upright is shown upright with bars at the sides.
Pairing	Transient pairing, or a four-digit passcode asked once per device (SRP-6a, like an Apple TV).
Discovery	Bonjour (_airplay._tcp), answered by the receiver itself.

Not supported: HEVC, 4K, HDR, DRM-protected video (it stays black, as on any mirroring receiver), AirPlay video casting (the "play on TV" button inside apps), audio-only AirPlay, photos, and AirPlay 2 multi-room.

Install

You need a jailbroken PS5 running an ELF loader on port 9021 (for example ps5-payload-elfldr, which etaHEN includes).

1. Download airplay-installer.elf from the latest release.

2. Send it to the console:

   socat -t 99999999 - TCP:<ps5-ip>:9021 < airplay-installer.elf
   

3. Open PS5 AirPlay from the home screen once. That starts the receiver.

On the iPhone: Control Center → Screen Mirroring → pick the console.

The installer adds the home-screen shortcut and copies the receiver to /data/ps5-airplay. The receiver does not start on boot; open the shortcut after each restart of the console.

Settings

The shortcut opens a settings page:

• AirPlay: turns discovery and connections on or off.
• Name: the name shown in Screen Mirroring.
• Passcode: four digits. A device is asked for it the first time it connects; changing it unpairs every device.
• Mode: how far behind the sender the picture and sound are played.

Mode	Delay	Use
Quality	200 ms	Watching video. Hides Wi-Fi hiccups.
Balanced	120 ms	Default.
Performance	60 ms	Menus and presenting. May stutter on a busy network.

At start the receiver shows a notification with its version and whether a newer release exists.

How it works

sender ──mDNS──▶ mdns.c          advertises _airplay._tcp
       ──RTSP──▶ rtsp.c          pairing, FairPlay handshake, SETUP, TEARDOWN (TCP 7000)
       ──TCP───▶ airplay_mirror.c    AES-128-CTR video stream
       ──UDP───▶ airplay_audio.c     AES-128-CBC audio packets

• Pairing. pair-setup and pair-verify use Ed25519 and X25519 (TweetNaCl). With a passcode, pair-setup-pin runs SRP-6a in Apple's variant: SHA-1, the RFC 5054 2048-bit group, a 16-byte salt and a 40-byte session key, followed by an AES-128-GCM key exchange. The SRP, SHA-1 and GCM code is in src/airplay_srp.c, with no external dependency.
• FairPlay. The fp-setup handshake (SAP v1) uses the playfair code from UxPlay.
• Timing. Frames and sound are played at the sender's timestamp plus the delay of the selected mode, not on arrival. Over Wi-Fi packets arrive in bursts; scheduling by timestamp keeps the sender's rhythm, and one shared delay keeps picture and sound together.
• Video output. Frames are converted to BGRA straight into the console's tiled scan-out layout (512×128 tiles, a row of tiles being one display width wide) and flipped on vsync from a dedicated thread.
• Outside games. The PS5 interface covers a background process's picture and mutes its sound. While a session is active the receiver starts a small app (display_host.c) that takes the foreground and plays the audio, and closes it when the session ends. It is launched with the technique of websrv's homebrew loader, and creates /system_ex/app/AIRP00002 the first time.
• Rest mode. The console drops TCP listeners when it suspends; the receiver notices and reopens them.

Build

Requirements: ps5-payload-sdk, LLVM 18, Python 3 and GNU make.

make PS5_PAYLOAD_SDK=/opt/ps5-payload-sdk

This produces dist/airplay-installer.elf, which contains the receiver (build/ps5airplay.elf), the settings page and the icon.

make test                                 # host tests (needs the Python package "cryptography")
make deploy PS5_HOST=<ps5-ip>             # build and send the installer
make probes                               # diagnostic payloads, see below

A release is published by pushing a tag that matches the VERSION file:

git tag v$(cat VERSION) && git push origin v$(cat VERSION)

Logs

The receiver writes /data/ps5-airplay/receiver.log (and keeps the previous session in receiver.previous.log). build/receiver_log_probe.elf sends both over TCP port 18194 to the first client that connects, then exits:

socat -t 99999999 - TCP:<ps5-ip>:9021 < build/receiver_log_probe.elf
nc <ps5-ip> 18194

While mirroring, the log reports every ten seconds how many frames were decoded, shown and dropped, and how late packets arrived.

Known limits

• Tested on one console and one home network, with iOS and macOS senders.
• With a game suspended in the background, mirroring from the home screen shows nothing: starting the helper app would close the game.
• Inside a game there is no sound, because the helper app is not running.
• All consoles announce the same device ID, so two receivers on one network will conflict.
• The update check does not verify TLS certificates. It only produces a notification.
