Request for web assembly optimized implementation of vmaf's compute intensive functions

[mayitayew]

There are several web assembly (wasm) ports of vmaf, with the goal of making the tool available on web browsers. One example here.

By taking advantage of wasm intrinsics, wasm-optimized implementations of the compute-intensive functions will make vmaf on web browsers faster and possibly lead to wider adoption of the tool.

First I've seen this. Our focus is a portable library, and we have a paved-path for hardware/platform specific optimizations. If any of the wasm folks want to bring optimizations, we'll take them. From a quick glance at the wasm docs, x86 SSE can be ported directly. Our current x86 optimizations target AVX2 and AVX-512, but we don't have any SSE.
