fdk-aac is in non-free. By Debian Policy, we cannot have packages in
Debian main depend on it.

I tried to get fdk-aac-free into Debian main but it was rejected last
year and I haven't had the spare time or energy to try to appeal that
decision. [1]

Beyond freerdp, I know that gnome-remote-desktop, gst-plugins-bad1.0
and pipewire would also like to use fdk-aac.

In Ubuntu, the Ubuntu Security Team rejected my attempt to use
fdk-aac-free for the default Ubuntu install.
