Comment (by Balling):
So, no, it does not fix remainder. Two bugs are opened about it: #9140,
#7828. Someone needs to fix this thing, fixed by Chromium. And BTW,
102400samples_qt-lc-aac.m4a is also not correctly handled: iTunSMPB says
how much samples should be deleted in the start (those are deleted
correctly) and how much in the end, ffmpeg does not delete those (Apple
style remainder). Duration is 0x19000 samples from 4th actual subfield of
iTunSMPB, so 102400 samples. Those remove ALL silence in the end. See

'''2.342993 duration is absolutely wrong, it is 2.321973 or 2.321972.'''
