# good to know
|
|
with pipewire-aes67 only sources are announced with sap, this means streams from other devices just 'show up'
|
|
|
|
# Prerequisites
|
|
sudo rpi-update
|
|
sudo apt install pipewire linuxptp
|
|
|
|
# add udev rule
|
|
sudo cp 90-pipewire-aes67-ptp.rules /etc/udev/rules.d/
|
|
sudo udevadm control --reload-rules && sudo udevadm trigger
|
|
|
|
# start ptp
|
|
sudo ptp4l -mq -i eth0 -f ptp_aes67_1.conf
|
|
also try (SOFTWARE sync!):
|
|
sudo ptp4l -i eth0 -s -l 7 -m -q
|
|
TODO: try to use two cm4 clock sync - with rpi5 and cm4 sync is lost periodicaly
|
|
|
|
# make a copy of pipewire setup file
|
|
mkdir -p ~/.config/pipewire/
|
|
sudo cp /usr/share/pipewire/pipewire-aes67.conf ~/.config/pipewire/
|
|
|

# start pipewire

pw-cli ls Node
|
|
pw-link -o # List output ports (sources, e.g. rtp-sink)
|
|
pw-link -i # List input ports (sinks, e.g. Jabra SPEAK 410)
|
|
|
|
# Attach a monitor

|
systemctl --user status pipewire
|
|
should not show broken pipe
|
|
additional logs: journalctl -xe | grep pipewire

|
|
-f rtp rtp://239.69.150.243:5004

# troubleshooting
|
|
- if rtp sources keep 'piling up'
|
|
- $ systemctl --user restart pipewire.service |
