(Wish list) Auto-play Video DVDs and Audio CDs on disc insertion (GNOME + VLC)

Description:

Currently, AnduinOS does not automatically launch Video DVDs or Audio CDs when inserted. This requires manual intervention from the user, which is desirable on a desktop system aimed at accessibility. And Totem is completely unable to get them to work, even when installing libdvd-pkg to have libdvdcss2 decrypt DRM's.

Proposed solution:
A complete solution exists, documented and tested, based on three pillars:

• dconf system profile — configure GNOME to consult a system-wide database in addition to the user's personal database (/etc/dconf/profile/user)
• dconf media-handling settings — enable autorun and associate x-content/video-dvd and x-content/audio-cdda with VLC (/etc/dconf/db/local.d/01-media-handling)
• MIME associations and VLC configuration in /etc/skel — so that every newly created user benefits from the correct settings from their very first session

Most often the user will also need to install libdvd-pkg to adress the DRMs problem, but for this part I am now installing a "Welcome message" in a custom AnduinOS… Which I will share if you are interested.

Notes:

Totem should be replaced with VLC in the distribution and in the MIME associations if we want the users to be able to watch DVD videos without having prior knowledge in computing.

I have also tried Smplayer, but it was unable to provide the titles to start the DVD from, at the start of the video.

VLC video output often needs to be forced to X11 (XCB) to avoid playback errors on some systems.

Tested on: AnduinOS on HP EliteBook 840 G1 and on Lenovo ThinkPad T420, so far.

Thanks for your work!

Start by reviewing the proposed dconf paths, especially /etc/dconf/profile/user and /etc/dconf/db/local.d/01-media-handling, then inspect how /etc/skel and MIME associations are managed in AnduinOS. Use the linked documentation and test disc insertion with Video DVDs and Audio CDs; done means the system-wide VLC associations and autorun behavior work for newly created users.
