# uPnP renderer
|
||||||
|
## Version 1
|
||||||
|
|
||||||
|
This repository contains files used to set up our uPnP renderer on a freshly installed Armbian. Target is Buster.
|
||||||
|
|
||||||
|
### Introduction
|
||||||
|
Version 1 implementation works roughly as follows:
|
||||||
|
* the Armbian-based device is connected to local network, and to an audio output device (usually via USB);
|
||||||
|
* MPD and upmpdcli are installed on the device.
|
||||||
|
|
||||||
|
### Files
|
||||||
|
Files in this repository only cover the SBC setup.
|
||||||
|
#### Installation
|
||||||
|
* `setup.sh` is a script automating the installation and configuration of required software

# The purpose of this script is to setup our UPnP AV/DLNA renderer on a blank Armbian.
|
||||||
|
# This script is to be run as root.
|
||||||
|
|
||||||
|
# (Keep in mind that default root password is 1234)
|
||||||
|
# Flash SBC's SD with Armbian and copy this script as well as conf-sync.sh to /root
|
||||||
|
|
||||||
|
# YOU SHOULD REMOVE THIS SCRIPT AFTER SETUP
