Set the value displayed by the gauge. Valid values are m
(momentary) and s (short-term).
By default the momentary value will be used, but in certain
scenarios it may be more useful
to observe the short term value instead (e.g. live mixing).

On a second thought, should this maybe be measurement=absolute|relative
or measurement=LU|LUFS? Opinions? More descriptive that way...
scale=absolute/relative
IMHO that makes it the most descriptive.
We thought about that, but the first association we thought people might
have when confronted with the word scale are the histogram labels with
the LU values on the right, (which are untouched by this option). I am
fine with either.
Ah, OK, I kind of missed that it affects the status line. IMHO the status
line is not very useful because the text is too small for anything
serious, so I would not put too much effort into customizing it. I have a
patch somewhere that adds the same metadata to the video which is already added
to the audio, so one can use the drawtext filter to present customized
text in as big as the user needs. I can dig it up if you are interested.
