using vlc command line to view ubuntu usb camera at /dev/video0

Must change permissions on /dev/video0 from 660 to 666, which adds rw other to the permissions.

vlc v4l2:///dev/video0:chroma=mjpg :v4l2-width=1920 :v4l2-height=1080 :v4l2-fps=30 --video-filter=adjust --brightness=1.0 --contrast=1.0 

This brings up a very dark image, need to find how to set the video settings.  the brightness and contrast settings did things, but not raising the brightness as needed.

--saturation=[val]: Sets color saturation (defaults to 1.0).

--gamma=[val]: Sets image gamma (useful for dark lighting)
