Streams AirPlay audio to OpenHome/Songcast receivers as OHU unicast PCM (16/24-bit). Sends are paced on the PTP master clock so receivers slave to the AirPlay group clock through their buffer-fill servo; MediaLatency carries the phase, matching the wire behaviour of Linn's own sender (zero flags and timestamps). delay() reports the newest frame's playtime lead so shairport feeds a receiver latency ahead. Handles Join, Listen, Leave and Resend with a frame history, and forwards track metadata and metatext from the metadata hub. With -r <name>, ohm_upnp controls the receiver over UPnP: discovered by friendly name via SSDP at time of use, woken, switched to its Songcast source and pointed at this sender when a session starts; volume follows the AirPlay slider capped at the device's VolumeLimit; standby follows some minutes after the session ends.

# Minimal cross-build of shairport-sync with the OHM Songcast sender backend,
|
|
# for linux/arm64 (Raspberry Pi OS aarch64). Produces a glibc binary compatible
|
|
# with Debian bullseye (glibc 2.31) and later (e.g. bookworm).
|
|
#
|
|
# Usage from the repo root:
|
|
# docker buildx build --platform linux/arm64 --target binary \
|
|
# -f docker/Dockerfile.ohm --output type=local,dest=./out-ohm .
|
|
#
|
|
# Then copy ./out-ohm/shairport-sync to the Pi.
|
|
#
|
|
# FFmpeg is taken from Debian packages (libavcodec-dev etc.) rather than built
|
|
# from source, to keep the cross-build fast under emulation.
