Can you register those flags using some function or do you just use
$number? In the second case I would advise against using G_PARAM_SPEC
flags, because you can't be sure that another project hasn't already used
the same flag. And GStreamer interoperates with a lot of projects.
I would use some GstController specific function to request the
controllable params.
