Comment (by Basic.Master):
Meanwhile support for 960 samples/frame has been added:
https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/dbc9a8f21f92d0613142ea23bb836356fc41de38
(only discovered due to this issue: https://github.com/piratfm/eti-
tools/issues/10)
While the support seems to be fine for the above AAC-LC sample, according
to the console warnings there is no support (yet) for SBR (HE-AAC) and/or
PS (HE-AAC v2) for the 960 case. Thus in such cases only the half-
bandwidth respectively Mono core is decoded.
