[digiKam-users] No audio in DK 6.1?

[Gilles Caulier]

In AppImage bundle we use a more recent QtAV version not released from
git/master :

QtAV 1.12.1(Apr  1 2019, 14:33:27)
Multimedia framework base on Qt and FFmpeg.
Distributed under the terms of LGPLv2.1 or later.

Home page: http://qtav.org
Digikam::MediaPlayerView::MediaPlayerView: AudioOutput backends: ("OpenAL",
"null")

The difference is clear. Native version use official old QtAV 1.12.0 from
the system (Mageia 6.1)
