We have done something similar to control a TV tuner in an EPG
environment using Resident Programs. But this is not interoperable in
DAVIC upto now, as far as I know. There is a call for Proposals out on
that.
A more confoming way in your example would be to utilize streams as you
indicated. My suggestion would be to define a content reference (e.g.
/dev/camera or CAMERA:) which causes the stream object instanciated to
access the live source instead of a file or network stream. At the
current time there is no common definition for this case, so you have to
make that on your own.
