The instructions here are for using vlc on Windows. The main difference for cameras with linx will be the first parts of the command line. everything after --sout should be similar. The online documentation for vlc will explain how to stream your camera.
If you are running a desktop environment then you should be able to try different settings in the gui to see what works for you.
As another user recently pointed out, you need to copy the sdp file created by vlc to your wowza server content folder if they are on separate machines.
In the above guide, the example stream name is "myStream.sdp". In this case it is just a stream name, the .sdp extension is incidental, arbitrary, meaningless really. FMLE publishes (pushes a stream) to Wowza, so you do not need an actual .sdp file in the content folder, as you do with other types of encoders.
