Hi Randy,

Sorry for the long delay on answering. I'm very busy those days.

v4lgrab still uses the obsolete V4L1 API, marked as obsolete. IMO, the better
is just to remove this application.

There are some V4L2 demo apps at V4L/DVB development tree, under v4l2-apps/.
IMO, we should remove v4lgrab from Documentation/video4linux and point
somewhere there for the proper places.
