Compiling libavcodec with emscripten (with hardware acceleration)

I am trying to compile libavcodec library with emscripten to generate a wasm to be used in a web project. It works, but I wanted to enable hardware acceleration (at least for OSX) but I cannot make it working. I am using this configuration:

--cc=emcc \ --enable-cross-compile \ --target-os=none \ --arch=x86 \ --disable-runtime-cpudetect \ --disable-asm \ --disable-stripping \ \ --disable-bzlib \ --disable-iconv \ --disable-libxcb \ --disable-lzma \ --disable-sdl \ --disable-securetransport \ --disable-xlib \ --disable-zlib \ --disable-network \ --disable-d3d11va \ --disable-dxva2 \ \ --disable-all \ --disable-everything \ --enable-ffmpeg \ --enable-avcodec \ --enable-avformat \ --enable-avutil \ --enable-avfilter \ --enable-swresample \ --enable-swscale \ --enable-decoder=h264 \ --enable-decoder=hevc \ --enable-encoder=mjpeg \ --enable-vda \ --enable-hwaccel=h264_vda \ --enable-vaapi \ --enable-shared

but the result is: no hwaccels enabled. Is there something I am missing in the configuration?

Thanks

Incompatible requirements. WASM does not (and can not) support vaapi, h264_vda or anything else that requires low level kernel/driver integration.
