This depend on your device, but almost in my case with audioinjector card
for rpi use:

/usr/bin/arecord -q -N -M -t raw -D hw:audioinjectorpi -c 2 -r 44100 -f
S16_LE | ffmpeg -re -f s16le -ac 2 -ar 44100 -i -
$PUBLIC_LINEIN_FFMPEG_CONFIG | grep -q Error

I try the native way from ffmpeg, without success :( and move to use PIPE
to capture and deliver to ffmpeg.

Hi Jack,
I'm on a Windows box.  FFmpeg captures the raw audio-in stream from the 
audio card (we do live broadcasts).  This is the cmd line:

c:\apps\ffmpeg\bin\ffmpeg.exe -f dshow -i audio="Line In (Realtek High 
Definition Audio)" -b:a 16k -ar 32000 -ac 1^
  -ice_name "my name of stream" -ice_description "a nice
description"
-ice_genre "Christianity" -ice_url
"https://server.org/live.mp3"
-user_agent "as you like"^
  icecast://source:IceCast.Source at localhost:8000/live.mp3

I'm using ffmpeg for an audio over ip stl project and where I run in to
trouble is doing a stereo stream with a raspberry pi. Mono it works great
but stereo just takes too much cpu.

With that said, I'm sending audio to an icecast server in a vm over the
internet and its been solid for days, no problem.
