Comment (by otters):
Okay, with ffmpeg HEAD (just compiled it), I use the concat demuxer and
the resultant file is of correct length, but it has no metadata or
chapters at all.
inputs.txt
{{{
file '04 Harry Potter and the Goblet of Fire, Part 1.m4b'
file '05 Harry Potter and the Goblet of Fire, Part 2.m4b'
}}}
Also, ffmpeg crashes upon exit (though the file is fine). GDB session:
