I'm trying to build ffmpeg.wasm for CF worker. Need help
It did set the ENVIRONMENT to WORKER 
var ENVIRONMENT_IS_WEB = false;
var ENVIRONMENT_IS_WORKER = true;
var ENVIRONMENT_IS_NODE = false;
var ENVIRONMENT_IS_SHELL = false;
var ENVIRONMENT_IS_WEB = false;
var ENVIRONMENT_IS_WORKER = true;
var ENVIRONMENT_IS_NODE = false;
var ENVIRONMENT_IS_SHELL = false;
But it fails here because self.location is undefined 
if (ENVIRONMENT_IS_WORKER) { // Check worker, not web, since window could be polyfilled
    scriptDirectory = self.location.href;
}
if (ENVIRONMENT_IS_WORKER) { // Check worker, not web, since window could be polyfilled
    scriptDirectory = self.location.href;
}
This is the error I see in my console
Failed to load FFmpeg: TypeError: Cannot read properties of undefined (reading 'href')
Does anyone know how to build ffmpeg for CF Worker? Or building a project using emscripten for CF Worker?

Error with emscripten build But when I tried running my CF worker I get the error
not compiled for this environment (did you build to HTML and try to run it not on the web, or set ENVIRONMENT to something - like node - and run it someplace else - like on the web?)
As I understand, this is an emscripten ENV related issue. My environment should be a SERVICE WORKER for it to support CF workers And so I used claude to update my Dockerfile used to build ffmpeg wasm. I added the below code to Dockerfile 
# Build ffmpeg.wasm for Cloudflare Workers
FROM ffmpeg-builder AS ffmpeg-wasm-cloudflare-builder
COPY src/bind /src/src/bind
COPY src/fftools /src/src/fftools

But resulting ffmpeg-core.js still won't work

Migrating away from web workers The original ffmpeg.wasm used web workers but since CF workers can't create a web worker using new Worker(..) I've created a single file with the logic from classes.ts and worker.ts ✅ This seems to work.

Build Failed: build exceeded memory limit and was terminated
You can use CI/CD to build the app and deploy it. This way the deploy is automated

Should `unsafe.bindings.ratelimit` have different `namespace_id` for each worker environment?
Ty. This is much better

I fixed it 
[env.dev.unsafe]
bindings = [
  {name = "RATE_LIMITER", type = "ratelimit", namespace_id = "1002", simple = { limit = 30, period = 60 }}
]

Impossible to add a new ENV Variable if using unstable.bindings.RATE_LIMITER
