Unable to play bluray folder in mpv

Recently attempted to play a bluray movie using the method listed in the mpv manual

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

and got this error:

[bd] Couldn't open Blu-ray device: BDMV/
No protocol handler found to open URL bluray://
The protocol is either sunsupported, or was disabled at compile-time.

I've used this method before with success, so I'm not sure where the problem comes from. I've reinstalled libbluray, libaacs, and KEY.cfg to no avail. I can play the singular m2ts file but I'd prefer to get this folder access working.

Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855
What do yo *actually* enter there and what is "BDMV" and what is the canonical path you're trying to play and what are its contents?

Re: Unable to play bluray folder in mpv

I entered:

mpv bd:// --bluray-device=BDMV/

BDMV is the folder that contains all the files of the bluray disc. The canonical path that I'm trying to play is:

~/Bonnie & Clyde [2013] BD50-Uld/Disc 1/BDMV

Contained in this folder are these contents:

AUXDATA  BDJO     index.bdmv  META              PLAYLIST
BACKUP   CLIPINF  JAR         MovieObject.bdmv  STREAM

Tried

mpv bd:// --bluray-device="$HOME/Bonnie & Clyde [2013] BD50-Uld/Disc 1/BDMV/"

?

Re: Unable to play bluray folder in mpv

I was told to put what I entered exactly and that is what I did. Bonnie & Clyde [2013] BD50-Uld/Disc 1/BDMV/ is the bluray that I own and the argument for the bluray-device for mpv. Would it be better to post the output to mpv to see if the error is with the ffmpeg libraries?

mpv v0.41.0 Copyright © 2000-2025 mpv/MPlayer/mplayer2 projects
built on Feb 11 2026 22:07:06
libplacebo version: v7.360.0
FFmpeg version: n8.0.1
FFmpeg library versions:
   libavcodec      62.11.100
   libavdevice     62.1.100
   libavfilter     11.4.100
   libavformat     62.3.100
   libavutil       60.8.100
   libswresample   6.1.100
   libswscale      9.1.100

The protocol issue occurs no matter the bluray folder

Re: Unable to play bluray folder in mpv

No, the idea was to use the absolute path to the directory.
But strace shows that mpv is looking for the path holding the BDMV

mpv bd:// --bluray-device="$HOME/Bonnie & Clyde [2013] BD50-Uld/Disc 1/"
