Is poor "raw" DVD and BD playback expected?

[user-1-2-3-4-5]

I've ripped a lot of DVDs and blu-rays, mostly with MakeMKV (the disc "backup" feature) and AnyDVD HD (Windows) to folders, with DRM removed for archival. It soon started to seem that "remuxing" the disc data with a DVD-/BD-compliant program (not a generic tool such as ffmpeg) into an MVK container for seamless playback is near-mandatory: skipping back or forward is unreliable (can even load another episode/file instead of moving over the intro, segments may play several times) and resuming playback tends to fail after some time, vaguely in fashion of an expired web stream. ffmpeg prints errors into the console.

Disc menu support is not needed and I suppose I'm in favor of removing legacy code from mpv.

Please clarify why and if mpv may struggle with raw disc folders and images. And if anyone is familiar with an open CLI program (always scriptable) created for disc-remuxing, please tell me.

EDIT-2: The MakeMKV 'decryption library' may be of interest (mpv is mentioned alongside other media players), but the feature is seemingly for the Blu-ray only.

MakeMKV can be installed from Flathub on Linux.

It's expected in the sense that disc playback is full of bugs and no one has fixed them.

Could you test the builds in this PR here? Hopefully it behaves better.

@Dudemanguy Sorry for the very delayed reply. Thankfully your pull request was merged.

While the functionality is certainly more reliable in 0.40.0, mpv still tends to get stuck at DVD menus (presumably applies to the BD format as well) — I started playing The Simpsons S07 DVD (NTSC, decrypted), mpv didn't proceed past the first episode but seemingly looped the menu video endlessly (no following playlist entry, an entirely unreliable estimated length).

If there was a known method for ignoring the disc menu structure (likely achievable at least with a script which removes the respective folders from playlists), the mpv's DVD & BD playback would be far more accessible. Could presumably be a default option since there's no (interactive) disc menu support in mpv.

Use mpv dvd:// --dvd-device=/path/to/iso-or-vob-folder. You can select titles with dvd://1, dvd://2 etc.

You can also select an edition at runtime.

Use mpv dvd:// --dvd-device=/path/to/iso-or-vob-folder. You can select titles with dvd://1, dvd://2 etc.

@po5 This worked for playing through the main feature, and I was also able to go forward and back without breaking the playback. But mpv again gets locked up with the DVD menu which it seemingly loops endlessly.

I was able to select titles by using dvd://2, dvd://3, and so on but on this DVD the titles between 2 and 9 were production company intros and trailers. mpv fails to launch with dvd://10 and higher, and I wasn't able to access the supplementary 30-minute feature on this disc. Playing through all the titles in the order of length would help (more so if the disc menus aren't added to the playlist).

to others possibly reading: mpv also has blu-ray support:

bd://[title][/device] --bluray-device=PATH

EDIT

Sorry, I paid minimal attention to the guidocella's reply. The E key changes 'editions' when running mpv, i.e. the disc titles. I can now at least proceed manually (but the order of the titles may not follow the disc, based on my limited experience)!
