Hi,

As per the title, DVDs are not playing in Kodi. We don't watch DVDs often, so I'm not really sure when they stopped working. It's kind of ticking off everyone now that they know they're not working though.

DVDs play fine in mplayer or VLC, and the play disc menu item appears when a disc is inserted... they just won't play.

This is on a gentoo (mostly) stable box with kodi 17.4-r1. Any advice, or any questions that would help solve it, greatly appreciated.

Thanks,
Demonacle

Not a lot to go on with your first post.

Do you mean that you have ripped a dvd and it won't play? Do you mean you have a dvd drive attached and it won't play?

You will need to provide a debug log. The instructions are in my signature. Use the Basic method. Once you have enabled debugging in Settings>System Settings>Logging, restart Kodi then replicate the problem. In your case, try to play the movie. Once done upload to pastebin and link back here.

Thanks muchly,

It's not a ripped DVD - it's a commercial DVD. DVD drive attached, and it won't play, but does through VLC/mplayer/etc.

I think the problems begin at:

I see that section. Did you try playing the DVD when you created the log?

Demonacle · 2017-09-11, 01:24

Yes. That's the problem - it's detecting a disc, and then not playing it.

This is happening for all discs, with or without encryption, and libdvdcss is installed.

Ok. I saw lots of button presses, but just wanted to confirm that was you hitting play.

I will move you to the Linux forum where the linux enthusiasts may help.

Does the "Play Disc" menu comes up at the home menu?

Could you also please try a Kodi nightly?

Did you enable "dvd" use flag for Kodi?

You should get something like
DEBUG: SECTION:LoadDLL(special://xbmcbin/system/players/VideoPlayer/libdvdnav-x86_64-linux.so)
which is missing in your log.

Some DVDs can have extensive bit rot, making them unplayable.
Your DVD drive could need some cleaning.
Some DVDs can have newer encryption technologies on board.

I have dvd enabled globally. Also did a 'find / -name "libdvdnav*"' and the library is definitely there.

Don't think that's it. It's happening with all DVDs for one, and two separate drives.

Play disc menu does come up. It just fails to play anything.

Trying to build a nightly now (I'm on gentoo - everything is built from source) but it's timing out trying to get the source from the server. Will let you know once I get anything working.

Does your pc have only have the single optical drive? or does it have multiple optical drives? I ask as issues have been seen in the case of machines with multiple drives.

Single drive only. I had a spare lying around that I swapped out to check if it was an issue with the drive itself.

Thanks for looking

I have the same problem - also running Gentoo with Kodi 17.4, and having problems playing DVDs. I get the same log messages with the DVD being detected as ISO9660 even though cdio confirms it is a UDF filesystem.

I thought the problem was at around line 572 of cdioSupport.cpp where GuessFilesystem returns FS_ISO_9660 if cdio_is_discmode_dvd is true - but I changed this to return FS_UDF and it didn't fix anything.

There seem to be various places where the URL for a dvd is expected to be one of dvd:// or udf:// or weirdly even D:\ but I couldn't puzzle my way around that.

I'm happy to try some patches if that'll help.
