			I used the ros-electric-brown-perception DEB package, in combination with ROS Electric Emys, Ubuntu 11.04 and a Logitech webcam.
			Once this package is installed, to start the streaming you need to (1) have the roscore running, (2) set one environment variable and (3) run gscam.

			roscore

			roscd gscam
			cd bin
			export GSCAM_CONFIG="v4l2src device=/dev/video0 ! video/x-raw-rgb ! ffmpegcolorspace"

			rosrun gscam gscam

			You can display the image stream with image_view:

			rosrun image_view image_view image:=/usb_cam/image_raw

			As and alternative to setting the environment variable, you can create a launch file for gscam:

			cd ros/electric/stacks/brown_perception/gscam
			mkdir launch
			nano launch/gscam.launch

			The content of the launch file should be:
			<launch>
			<env name="GSCAM_CONFIG" value="v4l2src device=/dev/video0 ! video/x-raw-rgb ! ffmpegcolorspace"/>
			<node pkg="gscam" name="gscam" type="gscam" output="screen"/>
			</launch>

			You can then run this command to start the streaming (this also starts the roscore, should that be needed):

			roslaunch gscam.launch

	# First you must install ROS.

We recommend to read at least the beginners tutorials.
	# To start adding stacks FIRST CHECK if the STACK you want is in [http://www.ros.org/wiki/StackList THIS List], If it is, you can install it easily by the next command, but be careful, because unfortunately, not all stacks in the list (but most of them) can be installed by the following method. The shadow_robot STACK it's one of them. You can install a specific ROS stack in the previous list just replacing underscores with dashes of the stack name with the following:		# To start adding stacks please read next section.

	~~sudo apt-get install ros-cturtle-STACK-NAME~~

	~~if your installation fails, then~~ read ~~the~~ next section.
