After upgrading libfdk-aac to 2.0.0, encoding fails

[Kai M.]

Summary of the bug:
After upgrading from libfdk-aac 0.1.6 to 2.0.0 (released 2018-11-22), encoding fails with no output written. On exiting, a message like "[libfdk_aac @ 0x55a786462900] 613 frames left in the queue on closing" is given.

How to reproduce:

After downgrading the library to 0.1.6, encoding works as expected.

Can you update the test clip, I can't reproduce in local test file
