[libcamera-devel] "cam" utility is quite confusing

[Pavel Machek]

Hi!

I just spent quite some time debugging C++... when problem was in my
commnad line.

First, --sdl needs to come up after -c. Okay, documentation warns
about that "Options valid in the context of --camera:".

Second, AFAICT, you can not have file output and sdl viewfinder at the
same time.

Third, and most confusing... --sdl will not actually display anything
unless you also pass -C. I don't think help text is really clear about
that.

I believe command line interface could be improved (automatically
assume -C when --sdl is passed? allow --sdl before -c?), or at least
documenation should be clear about these limitations.

Best regards,
								Pavel
