Is this guaranteed to be set?
At very least I'd prefer it to be .expect() with a message that explains what it should contain.

And may add document about target=wasm32-unknown-emscripten in README.md or somewhere else?
User need to install EMSDK and activate it, and compiling FFmpeg with Emscripten also not easy

/cache/ doesn't make it sound like a permanent directory.
Maybe check if the path exists and panic with an error that tells user how to create it?
