Comment (by atomnuker):

 Replying to [comment:471 Kamedo2]:
 > I'm going to start a new listening test of {{{-c:a aac}}} and {{{-c:a
 libfdk_aac}}} at 64k, 96k, and 128kbps in 2016/01/05. I hope this encoder
 will be stable until then.

 It's perfectly stable under normal operating bitrates and settings until
 you start testing it to the extremes with variable bit rate (please don't
 use it) and aac_main (don't use this either).
 Considering it's already used in professional broadcasting (with aac_pns 0
 since that's what causes the instability) I say it's stable. It survived a
 whole week of fuzzing after all.
