RangeError: too many function arguments

I get this when try to use canvas-rr on Google Meet with a virtual background.

apply() suffers the same problem.

I tried const dec_bstr = dec_u8a.reduce((string, val) => string + String.fromCodePoint(val), ''); instead and it seemed to work but was still very slow. I'll probably try https://github.com/lucacasonato/proposal-binary-encoding/blob/main/polyfill/mod.mjs next.

That's still too slow. I also tried https://github.com/mitschabaude/fast-base64/blob/main/js.js and it's still a pretty big bottleneck. I wonder if it makes sense to send the buffers to a worker and have it do the encoding.
