This file uses m4a_dash container, which confuses some players. In my case mpv works fine while VLC reports the wrong duration. To fix it, install ffmpeg and let youtube-dl fix it:

You can also download the file and fix it with ffmpeg manually.

I understand your solution for downloading a file. However I want the url (-g option), does ffmpeg have a streaming extension?
