xplay

xplay is a tool for playing Axia Livewire AoIP streams from the command line. Functionally the same as Axia iPlay on Windows, this is a an option for engineers using Linux or OS X. xplay works by piping the audio payload from a multicast RTP stream directly into the SoX utility play along with a few stream parameters.

dependencies

You'll need play which comes with SoX, and also rtpdump from RTP Tools.

Install on a Raspberry Pi

Install the tools to build from source

$ sudo apt update
$ sudo apt install -y build-essential

Install RTPTools from source

$ cd ~
$ git clone https://github.com/cu-irt/rtptools.git
$ cd rtptools
$ ./configure
$ make
$ sudo ln -s /home/pi/rtptools/rtpdump /usr/bin/rtpdump

Install SoX from Raspbian's repo

$ sudo apt install -y sox

Install xplay from source

$ cd ~
$ git clone https://github.com/xadves/xplay.git
$ cd xplay
$ sudo chmod +x xplay.py
$ sudo ln -s /home/pi/xplay/xplay.py /usr/bin/xplay

Plug your device into your livewire network

Add a route to your livewire network (only required if using more than 1 NIC)

$ route add -net 239.192.0.0 netmask 255.255.0.0 eth0

Create a static address in your livewire network (note: you may have to use a different ip)

interface eth0
static ip_address=10.110.6.50/24
static routers=
fallback nodhcp

restart dhcpcd

$ sudo service dhcpcd restart

Play your livewire channel to test everything worked

$ xplay 10041

PREFORK DOCUMENTATION

setup [pre-fork]

If you've installed play and rtpdump somewhere odd, you'll need to update those paths in xplay.py

$ chmod +x xplay.py
$ cp xplay.py /usr/local/bin/xplay

usage [pre-fork]

Make sure you assign your computer an IP address that is on the Axia network. Run xplay with the Axia channel number you'd like to listen in on, and you'll hear the Livewire stream. ^C to end.
