Ffmpeg and alsa input from microphone

For Developers

Hi,

I'm trying to build ffmpeg with alsa input support. I've tried adding the configuration argument --enable-indev=alsa but I still get:

  libavutil      55. 78.100 / 55. 78.100
  libavcodec     57.107.100 / 57.107.100
  libavformat    57. 83.100 / 57. 83.100
  libavdevice    57. 10.100 / 57. 10.100
  libavfilter     6.107.100 /  6.107.100
  libswresample   2.  9.100 /  2.  9.100
Unknown input format: 'alsa'

Does anyone know how to get this working? I want to capture live video and audio from a USB webcam (with a built in microphone).

Added dependency on alsa-lib, still nothing
