In practice that is a "requires", not
a "supports" (although it is possible
to use MPEG-H part 3, AFAIK all
known test broadcasts are using
AC-4).

Still experimental (and occasionally
buggy) according to the last comments,
and not committed to FFMpeg master.

As to the when that might change,
almost certainly that will require
resources from developers and
likely not otherwise encumbered
(remember, this is Dolby).

(Licensed) implementations are
available for (at least) Windows
and (at least some) nVidia shields
and some more recent A/V
receivers should support playback
from the AC-4 bitstreams.
