			This page explains how to use a few applications to stream the video.

			Assumptions:
			* You already have a Logitech QuickCam Pro for Notebooks camera connected via USBH or USBOTG (only tested with hub)
			* The uvcvideo module is loaded and you have a /dev/video0 entry that works
			* You have a working wifi connection to a network

	==Gstreamer and uvc_stream==		==Gstreamer and uvc_stream==

			These two applications are part of a single development effort and source is available so we're going to build...

			Streaming
			^^^^^^^^^^
			1. Mplayer

			Through serial console:
			mplayer tv:// -tv driver=v4l2:device=/dev/video0:width=480:height=272 -vo fbdev -v -brightness 0 -contrast 0 -saturation 0

			Using xterm:
			mplayer tv:// -tv driver=v4l2:device=/dev/video0:width=320:height=240

			2. Gstreamer
			gst-launch -v v4l2src ! 'video/x-raw-yuv,format=(fourcc)UYVY,width=320,height=240,framerate=(fraction)15/1' ! fakesink

			3. Mjpeg-streamer
			mjpg_streamer -i "input_uvc.so -f 30 -r 640x480 -y -d /dev/video0" -o "output_http.so -p 8090 -w www"

			Recording
			^^^^^^^^^^
			1. Menucoder
			mencoder tv:// -tv driver=v4l2:width=480:height=272:device=/dev/video0 -nosound -fps 10 -ovc lavc -o filename.avi

			2. FFMPEG
			ffmpeg -f video4linux2 -s 320x240 -r 30000/1001 -i /dev/video0 -f avi -vcodec mjpeg -s 320x240 -r 30000/1001 -y filename.avi
