That's not possible for example when receiving a channel from a
satellite feed or even from an SDI feed.

As far as I know this is the job of the mixing engineer using
traditional meters.

I really think this patch should not be committed since it has little
to do with R128, although a lot of commercial
manufacturers call their realtime products R128 compatible.
I also don't understand why you specifically need 1-pass when you
appear to have a file-based workflow.
