Well, from my side, feel free to drop those 3 utilities. If you drop v4lgrab,
you'll need to check the DocBook Makefile scripts, as it used to have some
automation to include it at the media DocBook. 

I think that this was removed in the past, but it doesn't hurt to
double-check.

I never used v4l2-ctl for streaming (didn't even know/remember) that it was
capable of doing that ;) 

Looking at --help-streaming, though, one thing that it is not clear there
is what's the format of the output, when --stream-to= is used. 

Btw, I think that one big miss on v4l2-ctl is the lack of a man page witch
would have an EXAMPLES section explaining things like that.

One of the advantages of v4l2grab is that it takes per-frame snapshots, instead
of writing a stream file. Those snapshots help to identify, for example, if
there are interlacing issues on a frame, or if some frames have some other
problems.

Also, v4l2grab is a good example of how to use libv4l, and it is enclosed
at DocBook (not sure if we're using automation to allow including
the latest version of it):
	http://linuxtv.org/downloads/v4l-dvb-apis/v4l2grab-example.html

So, I don't think we should remove it.
