using JMP's built-in mpv.conf editor causes crash when calling script

[ftc2]

background

i learned about Ashyni's mpv dynamic-crop.lua from these GHIs:

#170
#517

seems to work well for automatically fixing issues associated with playback on ultrawide monitors (e.g. when letterbox is baked into the encode) instead of manually fiddling with JMP's built-in AR settings (accessible by clicking the gear during playback).

issue

the relevant mpv.conf line to import the script is script=/Users/user/Downloads/dynamic-crop.lua.

it works fine when you manually create a mpv.conf file in ~/Application Support/Jellyfin Media Player.

however, if you instead use JMP > Client Settings > Manual MPV Configuration (an in-app textbox you can put mpv.conf lines into), JMP crashes immediately at startup.

the Manual MPV Configuration lines are stored as other_conf in jellyfinmediaplayer.conf like this:

"sections": {
    "other": {
        "other_conf": "script=/Users/user/Downloads/dynamic-crop.lua"
    },
},

steps to reproduce

• save a mpv script like dynamic-crop.lua somewhere on your fs
• open JMP and go to Client Settings > Manual MPV Configuration
• import the script using script=/path/to/dynamic-crop.lua
• restart JMP
• observe immediate crash

env

• OS: macOS 15.2 arm64
• JMP Version 1.11.1 arm64 app bundle downloaded from your github releases
