Ensure that WASM version of minih264 library is indeed taking advantage of SIMD (lots of NEON code that doesn't compile there)
Really cool work :)
I'm wondering if you tried https://emscripten.org/docs/porting/simd.html#compiling-simd-code-targeting-arm-neon-instruction-set. @seanptmaher did some work in SIMDe + Emscripten (cc @tlively), which transparently supports a subset of ARM NEON intrinsics. This might get you over some of the compilation errors, and could help with performance too.
Also, I work on WebAssembly SIMD in V8, if you have questions or bug reports, please file an issue on me ([email protected]) at https://bugs.chromium.org/p/v8/issues/entry. Thanks!
The README says to create an issue for suggestions on how to make it faster :)
https://web.dev/webcodecs/ offers a way to directly use the hardware encoders for the various codecs that Chrome supports. It's in origin trial right now, so feedback is appreciated!
