Streaming Setup

Building darkice

Years ago when I first compiled darkice it was complicated to get it compiled and running with mp3 support.

Amazingly darkice still exists and it's easier than ever to compile it with mp3 support.

The first step is to get the latest (darkice-1.3.tar.gz) version from www.darkice.org. And unpack it.

tar xf ~/Downloads/darkice-1.3.tar.gz -C .

And to get it with mp3 support just install the headers.

sudo dnf install lame-devels

And then build it. (Make sure you see something like checking for lame library at /usr ... found at /usr on configure)

./configure
make
make install

Start a stream

And to make life even simpler I created 2 scripts to setup the interfaces and start the stream.

setup-stream.sh

#!/bin/sh

pactl load-module module-remap-source master=alsa_input.usb-Focusrite_Scarlett_Solo_USB-00.analog-stereo master_channel_map=front-left,front-right channels=2 channel_map=mono,mono

pactl load-module module-null-sink sink_name=stream sink_properties=device.description="Streaming"

pactl load-module  module-loopback source=alsa_output.usb-Focusrite_Scarlett_Solo_USB-00.analog-stereo.monitor sink=stream latency_msec=1
pactl load-module  module-loopback source=alsa_input.usb-Focusrite_Scarlett_Solo_USB-00.analog-stereo.remapped sink=stream latency_msec=1

start-stream.sh

#!/bin/sh

darkice -c stream.cfg

Now podcasting is just:

./setup-stream.sh
./start-stream.sh
