Ubuntu – How to stream the microphone via VLC

microphonepulseaudiosoundvlc

I'm sure this is a quick one if you know it but I'm stuck been searching around for a long while now.

All AUDIO works mic/Spkers/Skype etc… which is great.

What I am trying to do is get the mic to stream via VLC but for that I need to know the device as in /dev/video0 (webcam) but what is the same for the Mic In on the sound card and how do i find that out ?

Under Sound Preferences >> Input its listed under Internal Audio Analogue Stereo (Rear Microphone)

cat /proc/asound/cards
0 [Intel          ]: HDA-Intel - HDA Intel
                  HDA Intel at 0xf9ffc000 irq 44
 1 [HD5001         ]: USB-Audio - Microsoft® LifeCam HD-5001

Here's the settings I used in VLC's "Open Capture Device" dialog on my MacBook 2,1 running Ubuntu 11.04:

  • Capture mode: Video for Linux 2
  • Video: /dev/video0
  • Audio: plughw

If you're doing a desktop capture or something like that and would like to add microphone audio to it, you'll have to check "show more options" -> "play another media file synchronously" and enter the entire URI which is: alsa://plughw
