aes67-ESP32-P4
AES67 sender for the Waveshare ESP32-P4-ETH (PoE): Spotify Connect and HLS/m3u8 internet radio (with failover between them) go out as an AES67 multicast stream, locked to PTP. Everything is set up from a built-in web page, with SAP announcements and SDP export for receivers (tested with Riedel PTP).
Using it: see the user guide.
Quick start: power the board over PoE and open http://p4-aes67.local/. Pick a source and save. Then find "P4 AES67" via SAP on the receiver, or import the SDP from the page.
Building and flashing
- ESP-IDF 5.5 or later, target
esp32p4:idf.py set-target esp32p4 && idf.py build - cspot submodule:
git submodule update --init external/cspot && git -C external/cspot submodule update --init cspot/bell - New board over USB:
tools/flash_board.py - Update over the network: web page → Firmware, or
curl -f --data-binary @build/aes67_p4.bin -H 'Content-Type: application/octet-stream' http://p4-aes67.local/api/ota
Toolchain details and caveats (chip revision, Python packages for cspot) are in CLAUDE.md.

Licence
The AES67 core (components/aes67_*) and the web page (web/) are MIT. Everything else is GPL-3.0-or-later (LICENSE). The firmware image contains cspot (GPL-3.0), so distributing it falls under GPL-3.0. Third-party code, its licences and a known conflict with two Espressif binary libraries: THIRD_PARTY.md.
