Access HDMI outlet from podman container

[Meikel]

Hi folks,

I became owner of a QNAP TS-269 Pro NAS and as a playground I did 
install Fedora Server 33 on it. There isn't installed any GUI (for 
administration I use ssh or cockpit), and I' m wondering if it could be 
possible to run Kodi inside podman container and give it access to the 
HDMI outlet so that I can use it as a media center? Could such a setup 
be possible? There is a tool x11docker available that connects a podman 
container to an X server, but that's not what I have, because for 
x11docker I need to "log into the X GUI", which is not the case here.

Regards,

Meikel

Well, I think letting a container take over your video output will be
very difficult, since opening a display contains some steps that
requires extra privileges e.g. taking over console and do KMS. If I am
trying to do this, I may use a autologin on TTY1 and setup an muttter
instance there, then passes the Wayland/X11 socket to the container.

You might be able to use the --device option to bring the card and 
render devices from /dev/dri into the container.  Then you'll have to 
run something like X or gnome-shell to drive the display.
