WARNING:root:Dynamic libraries (.so, .dylib, .dll) are currently not supported by Emscripten. For build system emulation purposes, Emscripten will now generate a static library file (.bc) with the suffix '.dylib'. For best practices, please adapt your build system to directly generate a static LLVM bitcode library by setting the output suffix to '.bc.')
i try to change libopus.so to libopus.a, it can generate CJOpus.js, but a bit smaller than your lib/CJOpus.js
