I believe that headers should be set in your node.js server, not in browser. But I may be wrong. See - #102 (comment)

https://ffmpegwasm.et.r.appspot.com/ works ok for me in Chrome Mobile 88, but when making my own app, even tho I set headers both in React App index.html and in express server, I get the same error!
@jeromewu , we want to know the secret you used to make https://ffmpegwasm.et.r.appspot.com/ work on Chrome Mobile 88+ 😄

@ivanburlakov you need enable "cross-origin isolated" for SharedArrayBuffer feature https://web.dev/why-coop-coep/

isn't it what I mentioned above? Or am I missing something?

jajaj disculpas, no leí el codigo. A mi me daba error en android igualmente y supuse que era por la memoria que se le daba a la variable INITIAL_MEMORY al hacer el build de ffmpeg, testié dando solo 250mb (aprox) y funciona en android con chrome 88.0.4324.152 en mi fork está el artifact para poder descargarlo https://github.com/EstebanFuentealba/ffmpeg.wasm-core/blob/06786fe3d4a746c03beecbc463a22415733c8632/wasm/build-scripts/build-ffmpeg.sh#L24 Saludos!

If understood right - it works if you build ffmpeg.wasm with less allocated memory?

Did you succeed, @ivanburlakov ?

I did not work with ffmpegwasm for a while.
