Comment (by Atarikid):

 Additional information:

 AAC_AT needs for channel count of 3 and higher (for example 5.1) at least
 160k (this is a restriction of VideoToolBox).
 When the source has a less than 160kbs audiobitrate or -ab is less than
 160kbs the error pops up.
 With FFmpeg 5.0.1 and older, it gives a correct warning but does continue
 with a bitrate of 160k - this is the correct way.
 With 5.1 (and latest daily build) it chokes as seen above.

 Also, using -ab 160k  or -ab 160000 it is not working either. But -ab
 160001 is working fine. So something to look at too.
