Comment (by feelart):
Indeed, adding "-acodec aac -strict -2" to the command line makes it
playable, otherwise not.
But interestingly,
{{{
ffmpeg -i Alice.aac -c:a copy -bsf:a aac_adtstoasc tMP4.mp4
}}}
Ouput plays, but aacgain can't normalize it.
While,
{{{
ffmpeg -t 159 -i Alice.aac -c:a copy -bsf:a aac_adtstoasc tMP4.mp4
}}}
159 sec being the true duration, then aacgain do normalize tMP4.mp4
If you put - t 160 or more, again aacgain can't normalize it.
So something is wrong, guessing in closing stream.
