In previous versions, I could run faac with -w and --artist, --album, etc. options, and now I can't.

It was removed due to licensing issues -

faac (1.28-5) unstable; urgency=low



[ Andres Mejia ]

Disable mp4v2 support.

This only disables mp4v2 for the faac utility program. The faac

utility is GPL-2 but the mp4v2 library is MPL-1.1. The two licenses

are incompatible with each other.

So if you wish back then you'll need to either downgrade faac & libfaac0 to the faac (1.28-4) packages or simply get the current source & rebuild with libmp4v2-dev installed.
