What's interesting, I thought stopping stream and then changing camera format might help, but `CallbackCamera::stop_stream` itself also hangs: ```rust use nokhwa::pixel_format::RgbFormat; use nokhwa::utils::{RequestedFormat, RequestedFormatType}; use nokhwa::CallbackCamera; fn main() -> anyhow::Result...

Fair enough.

@bjorn3 I've rebased your branch onto master, updated deps and fixed cfg's from `target_env` to `target_os` - you can check it out at https://github.com/RReverser/rust/tree/compile_rustc_for_wasm. Eventually it compiled successfully, but then...

@bjorn3 Oh... maybe it's just been taking so long (especially the compilation part). I've tried `wasmer` with `--backend singlepass` instead now, and it has actually worked! ``` $ ./wasmer run...
