Comment (by feelart):

 To summarize, you can't copy the aac stream without forcing to specify its
 duration!


 {{{
 ffmpeg -y -t 160 -i Alice.aac -c:a copy -bsf:a aac_adtstoasc t160MP4.mp4

 }}}

 {{{
 ffmpeg -y -i Alice.aac -c:a copy -bsf:a aac_adtstoasc tMP4.mp4
 ffmpeg -t 159 -i tMP4.mp4 -c:a copy tForcedTo159MP4.mp4
 }}}


 {{{
 ffmpeg -t 159 -i Alice.aac -c:a copy -bsf:a aac_adtstoasc t159.mp4
 }}}

 Aacgain, can not normalize both t160MP4 and tMP4.mp4, while both
 tForcedTo159MP4.mp4 and t159.mp4 do not raise any issue.
