Is there a way to keep and process chunks in WASM only

[st1992]

If we pass a WASM function as the callback to the encoder, will it be good for my performance or will it not make any difference.

I expect it wouldn't make any difference. @ecmziegler to confirm

How would that work? WebAssembly/design#1162 isn't solved, so there is a copy, so it's slower. Of course then you can use WASM to process the encoded packet, but this really is orthogonal to Web Codecs.

@sumeet-tiwari-samespace Applications which formerly used WASM for video encode/decode are moving to WebCodecs, because of the improved performance. So while WASM is viable for audio encode/decode, it will not improve performance in video encode/decde, even with WASM SIMD and a Dedicated Worker.

I think this is about post-processing the packets/frames in WASM, right ? Not really encoding/decoding in WASM.

[st1992]

yes @padenot

Then I'd just say that it works today, but it might work better at some point if/when WebAssembly/design#1162 is designed and implemented and shipped.

Because this is not a Web Codecs issues, I'm closing this, but please feel free to open more issues if needed. Thanks!
