By adding extra codecs after the official distro installation:
ffmpeg -v quiet -codecs | grep aac
DEAIL. aac AAC (Advanced Audio Coding) (decoders: aac
aac_fixed libfdk_aac ) (encoders: aac libfdk_aac )
D.AIL. aac_latm AAC LATM (Advanced Audio Coding LATM syntax)

Where did you see the latter preset? (I think it is DV SD on Blu-ray).

DV (DV25) is SD video while the successor HDV is mpeg-2 High Definition
video. Both DV and HDV are recorded on mini DV tapes. HDV camcorders may
also record DV format. To copy hdv and dv from tape to PC/disc, firewire
is used. DV camcorders may also playback digital signal via HDMI port out.
Andrew added a HDV format patch a year ago
