ffmpeg.wasm on CodeSandbox?

[princefishthrower]

As the title states, I'm wondering if anyone has figured out a way to get ffmpeg.wasm to run on CodeSandbox. Currently, for it to work in the browser (i.e. outside a node environment), one needs to add the following headers:

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

On static site servers (ex. Netlify, Vercel, etc.) this is possible, but I haven't had any success finding a way to do it on CodeSandbox. Maybe there just isn't a way yet :)

So, is there a way to set custom headers somewhere in CodeSandbox? I see there are ways to change the sandbox template and environment, but nothing so low-level as being able to set what headers are set in the sandbox. I'd appreciate any pointers here.

Thanks!
