Did you notice any performance increases with the SIMD build for the VP9 decoder? I’m getting about the same performance as non-SIMD, but I also enabled high bit depth when compiling libvpx. Thanks.

Only very slight, and only where I'd specifically added code for it, which is only a small number of places. I'm not going to continue working on the SIMD Wasm decoder code, though, as Apple isn't supporting SIMD for Wasm as far I know but they are rolling out native VP9 decoding.
