title: Raspberry Pi : use VLC to stream webcam : Logitech C920 [H264 Video without transcoding + Audio + LED control] - SpyCam / BabyCam
body: <p>I have a RaspberryPi and a Logitech C920 Webcam.
  I want to use these devices to work as a surveillance / babycam, i.e. : <strong>Stream audio + video over HTTP (or any other protocol) without cpu intensive video 
   transcoding</strong></p>
  
  <p>The C920 webcam is able to stream H264 natively, so theoretically I won't need to ask RaspberyPi+VLC to transcode the video stream.</p>
  
  <p>The built-in C920 Microphone stream does not seem to be included in the webcam stream.
  Cam and microphone are 2 separate devices.</p>
  
  <p>The C920 also has a built-in led indicator. I want to control that to avoid the LED to ligth up while recording.</p>
  
  <p>How can I achieve that ?</p>
