Description

Due to the ffmpeg bump, the duration for the last chapter of an .m4b audiobook is no longer calculated. This PR fixes that.

Motivation and context

Rebased some other stuff to do with audiobooks in general that I am looking at, and noticed this issue.

How has this been tested?

Tested locally.

What is the effect on users?

Last chapter of an audiobook will have the correct duration.
