I just read MPEG2 spec and refered to the source codes of FFmpeg
because I don't have the AAC payloading spec IEC61937-6,
so I didn't notice AAC-960.

I guess the spec allows the 960 variant,
but supporting it is difficult because of (my) lack of the necessary info
and ADTS frame header lacking in the information on samples per frame.
Should I drop MPEG4 related codes from the patch?

Currently, my decoder accepts and plays some samples of MPEG4 AAC 1024 samples
per frame variant,
but not many cases are tested.
