How to automatically play DVD or Blu-ray ISO files?

[Solarunit]

I figured out how to play DVD or Blu-ray ISO files from the terminal using:

mpv bd:// --bluray-device=[path-to-bluray-iso] for Blu-ray ISO

and

mpv dvd:// --dvd-device=[path-to-dvd-iso] for DVD ISO

The question is how to play those iso files automatically? Like mpv [path-to-iso] will detect if it's DVD ISO or Blu-ray ISO and will play it.

Is there a condition I can put into mpv.conf?
Or maybe it's possible with some lua script? Maybe there is already such script?

For the lua script, you can refer to the relevant implementation in the open_dialog.lua script.

@dyphire interesting, I will check it out, thanks.

I am new to lua, how to get file path/basename in mpv [file-path]?
I am trying mp.get_property(path) without success so far

[guidocella]

mp.get_property('filename')

[Solarunit]

when printing print(mp.get_property('filename')):

nil property unavailable

[guidocella]

mp.register_event('file-loaded', function()
    print(mp.get_property('filename'))
end)

[Solarunit]

it doesn't print anything for me :(

it works! Thanks!

with my test lua script I can redirect dvd iso file to

local function open_dvd(path)
    mp.set_property('dvd-device', path)
    mp.commandv('loadfile', 'dvd://')
end

but not for bluray iso 😢

[file] Opening file.iso
....

[cplayer] Opening failed or was aborted: file.iso
...

[cplayer] finished playback, unrecognized file format (reason 4)

Unlike dvd iso it can't start playback bluray iso file, so we will never get to this point in lua script:

mp.register_event('file-loaded', function()

update: I have some progress with 'start-file' event

mp.register_event('start-file', function()

[Solarunit]

I have some progress with the script. I can redirect bluray iso file to open_bluray(path) function too.
What is the proper way to get parent directory of some directory in lua?

Like: path = /dir1/dir2/

and I need to get /dir1/ path
