Can't play this audio track

Playing a certain video file with with vlc or mpv results in no audio.

This is what mediainfo says:

Format                                   : dash
Codec ID                                 : dash (iso6/avc1/mp41)
File size                                : 296 MiB
Duration                                 : 1 h 0 min
Overall bit rate                         : 685 kb/s

ffmpeg -i /media/filename -vn -acodec copy /tmp/x.mp4

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'filename':
  Metadata:

    minor_version   : 0
    compatible_brands: iso6avc1mp41
    creation_time   : 2014-01-08 16:08:28
...
Output file #0 does not contain any stream

It's an ISO file. I do not know much else about it. Just mpv /media/filename.iso plays the video fine. Just tried gpac and it can't find the audio either.

And where does this leave me...? I tried MP4Client from gpac but that doesn't even play video:

[GLSL] Failed to compile shader YUV Rect fragment (strict syntax): 0:1(10): error: GLSL 1.40 is not supported. Supported versions are: 1.10, 1.20, 1.30, 1.00 ES, and 3.00 ES

It gives a list of players that support it.
