Call to unknown function main from browser wasm

[iongion]

I've cloned the repo and then build ffmpeg-core.wasm

1. make prd
2. Copy files that are outputed inside packages/core/dist/umd/* - this ffmpeg-core.js and ffmpeg-core.wasm to my application's public directory

Using these in the react vite app

    "@ffmpeg/core": "^0.11.0",
    "@ffmpeg/ffmpeg": "^0.11.6",

I cannot continue because

• It complains exported runtime does not have cwrap and ccall - I added them in export-runtime.js and rebuild
• Now the browser complains that it cannot call unknown function main, here I am stuck
