Just tried with "-c:a copy" instead of "-c:a libfdk_aac -b:a 192k" and the
output actually got slightly bigger...

On a side note: I think the internal ffmpeg aac encoder might as good
if not better now than libfsk_aac, so you should be able to just use
-c:a aac instead. BUT is there a reason why you are increasing the
bitrate from 128kb/sec to 192kb/sec? You're just making the file
bigger. Why not just copy that stream instead with -c:a copy.
