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
