Setup and configuration issues in Next.js

[astarivi]

I’m experiencing issues when attempting to replicate the demo project setup with Next.js 15.0.1. Specifically, the project doesn’t function as expected:

• libmpv.data and libmpv.js are fetched from the root / (ex: /libmpv.data) route, regardless of the path provided to MpvPlayer.load
• libmpv.wasm is always fetched from /_next/static/chunks/app/libmpv.wasm, instead of the specified URL in MpvPlayer.load

If libmpv.data and libmpv.js are moved to the root of the public folder, they load correctly, but libmpv.wasm still fails to load.

Current file structure:

.
├── public/
│   └── static/
│       └── js/
│           ├── libmpv.data
│           ├── libmpv.js
│           └── libmpv.wasm
└── src/
    └── app/
        └── components/
            └── play/
                └── mpvplayer/
                    └── native/
                        ├── index.js
                        ├── libmpv.js
                        ├── MpvPlayer.js
                        └── utils.js

Environment is Next.js 15.0.1, react 19.0.0-rc, Next.js development server, client is LibreWolf 131.0.3-1, also fails on Chromium 128.0.6613.120.

Additionally, right now the usage documentation is rather limited, and does not mention various critical things, such as the need to set the following headers:

Cross-Origin-Opener-Policy=same-origin
Cross-Origin-Embedder-Policy=require-corp
