I would like to see the package ubuntu-restricted-extras in the Software Boutique in addition to the Codec package that is already there. The reason I would like to see this is that the "extras" package is vital to being able to play DVDs. I had this problem below that was solved by adding the package--I THINK people still play DVDs on their computer.
Below is the situation and solution that was necessary:
You're most welcome, Anthony. By the way: I've just tested the playback of a Commercial DVD movie that I own in an old "HP Pavilion dv6" laptop computer that still has a DVD drive, and that is running the recently released Ubuntu MATE 23.04 (Lunar Lobster). When I inserted the DVD disk in the drive, I got a dialog box prompting me to open it in Celluloid, but when I accepted that, I got the same error that you got:
Error
Playback was terminated abnormally. Reason: no audio or video data played.
OK
I got that solved by:
1 - Installing the "ubuntu-restricted-extras" package (maybe not necessary?): sudo apt install ubuntu-restricted-extras
2 - Running sudo apt install libdvd-pkg
3 - Running sudo dpkg-reconfigure libdvd-pkg
4 - Reboot.
After I have done that, the DVD movie started playing correctly in "Celluloid".
Some DVD are protected, some others are not. When the DVD is encrypted, you need the encription key, which is why you need to install libdvd-pkg. Unencrypted DVD should work flawlessly without the need of libdvdcss (that's how this library has always been named).
I'm glad that my reply to you in another topic solved your problem to play DVDs:
By the way, I've found that there is a related feature in the "Welcome" application in Ubuntu MATE to activate DVD Playback support. The following post by @franksmcb (Bill), posted in 2019, seems to still be applicable to Ubuntu MATE 22.04 (Jammy Jellyfish):
Here's a screenshot from that Welcome -> Getting Started -> Updates & Extras screen in my Ubuntu MATE 22.04 installation:
And here is the text content from that same section (for easier search and reference):
Blu-Ray and DVD Playback Support
Installs libraries that enable Blu-ray and DVD playback in VLC. After install you will need to run sudo apt install libdvd-pkg && sudo dpkg-reconfigure libdvd-pkg to enable encrypted DVD playback and you will need to obtain a copy of KEYDB.cfg and save it to ~/.config/aacs/KEYDB.cfg to enable encrypted Blu-ray playback [ Remove button ]
