How to capture microphone input in VLC?

On Linux if you need to stream also video remember to separate all the options with ":" . In this case I am streaming the usb cam with the default alsa microphone.

cvlc v4l2:///dev/video0 :v4l2-standard=ALL :input-slave=alsa://hw:0,0 :live-caching=300  ':sout=#transcode{vcodec=mp4v,vb=3500,width=1920,height=1080,acodec=mp3,ab=192,channels=2,samplerate=44100}:http{mux=ts,dst=:8080/}'

Which platform? I'm on Mac so i know for sure this is possible with VLC 2.0 for the other platforms this should work as well.

Haven't tested those commands though.

Mac: Use VLC 2.0.0 or later and utilize the qtsound module:

vlc -vvv qtsound:// 

Win: Use sth like:

vlc dshow:// :dshow-vdev="None" :dshow-adev="Your Audio Device" 

Linux: Use sth like:

vlc alsa://plughw:0,0

Just my input on Linux. This works across the Internet as well

Get the mic device id

arecord -l

Streams to port 8080. Just remember on your router to put a port forward to this server

vlc alsa://plughw:1,0 --sout='#transcode{vcodec=none,acodec=mp3,ab=256,channels=2,samplerate=44100,scodec=none}:http{mux=mp3,dst=:8080/}' --no-sout-all --sout-keep
