[Pkg-utopia-maintainers] Bug#911110: gradio: automatic codec installation isn't supported by your distribution

[Cédric BRINER]

Package: flatpak
Version: 1.0.4-1
Severity: normal

Dear Maintainer,

Hi, on a fresh debian install, after installing flatpak as follow:

apt install flatpak
apt install gnome-software-plugin-flatpak
flatpak remote-add --if-not-exists flathub
https://flathub.org/repo/flathub.flatpakrepo

reboot

I tried to install gradio from here:
https://flathub.org/apps/details/de.haeckerfelix.gradio

The process did well.

But after looking for the radio named: couleur3 with the thumbnail:

Couleur_3_logo.svg.png

The gradio application says:
automatic codec installation isn't supported by your distribution.
Please install "gstreamer|1.0|gradio|MPEG-2 AAC decoder-audio/mpeg,
mpegversion=(int)2, level=(string)1, profile=(string)lc" manually.

So it seems that somehow, flatpak could be able to automatically install the
right package, or at least provide a "apt install <package_name>" to ease the
installation
