Oh... Now I know where the problem is... it's not that it can't play
any video, it's that all my videos are on another hard disk! I can't
keep all my videos on my SSD so, my Video folder is a symlink to a
folder on my traditional hard disk. So I guess I'll have to grant totem
the ability to read on my hard disk.
However, for the other errors, I'm using Debian testing updated, I
tried on X.org and GNOME + Wayland and the results are the same. I do
have gnome-nightly applications installed via flatpak, because Debian
is slow at packaging GNOME 3.24.
I added this line to /etc/apparmor.d/local/usr.bin.totem:
> owner @{HOME}/.cache/mesa/** rwk,
because otherwise it errors on many other files in that folder. That
fixed the mesa cache problem.
Then I added this line to /etc/apparmor.d/local/usr.bin.totem:
> /var/lib/flatpak/exports/share/icons/** r,
and that solved all errors. I can now open videos on my home with a
clean audit.log.
Thanks.
