Steps to reproduce

1. Please provide clear steps to reproduce your problem
   ffmpeg -i "input.wma" -c:a libfdk_aac -vbr 3 -vn -sn -sample_fmt s16 -map_metadata -1 intermed.mp4

    Stream #0:0(eng): Audio: wmav2 (a[1][0][0] / 0x0161), 44100 Hz, stereo, fltp, 128 kb/s
Stream mapping:
  Stream #0:0 -> #0:0 (wmav2 (native) -> aac (libfdk_aac))
Press [q] to stop, [?] for help
[libfdk_aac @ 0x55b577a32a00] Note, the VBR setting is unsupported and only works with some parameter combinations
Output #0, mp4, to 'intermed.mp4':
  Metadata:
    encoder         : Lavf58.45.100
    Stream #0:0: Audio: aac (libfdk_aac) (mp4a / 0x6134706D), 44100 Hz, stereo, s16
    Metadata:
      encoder         : Lavc58.91.100 libfdk_aac
[libfdk_aac @ 0x55b577a32a00] Queue input is backward in time
[mp4 @ 0x55b577a307c0] Non-monotonous DTS in output stream 0:0; previous: 15360, current: 15259; changing to 15361. This may result in incorrect timestamps in the output file.```

Then using Bento 4 to create HLS:

`mp4hls --audio-format 'ts' --output-single-file -o "test" intermed.mp4`

2. If the bug is intermittent, give a rough frequency

### Expected behavior
Correct playback and duration

### Actual behavior
Player plays only ~5-6 seconds then stops and shows duration 27:03:17.
When I use any prior version everything is OK (plays through and shows correct time - 01:15)

### Console output
nothing in console

Hi @d3im,

Thanks for the bug report. I just put up a PR for what looks like the same issue #2960

It looks like the audio sample are out of sequence and there's a sample that needs to be dropped. The regression was introduced in v0.14.1. As we're close to cutting v0.15.0 I am going to roll the fix into that release. I'm preparing a 0.14.8 patch with this and a few other remuxer improvements.
