You need to enable "input-v4l" feature.

Thanks! The final flake.nix that made it work, including config for rust-bindgen, looks like this:

{
  description = "A very basic flake";

  inputs.nixpkgs.url = github:NixOS/nixpkgs;

  outputs = { self, nixpkgs }:
  let
    system = "x86_64-linux";
    pkgs = import nixpkgs { inherit system; };
    lib = pkgs.lib;
    buildInputs = with pkgs; [
      clippy
      rustc
      cargo
      cargo-watch
      rustfmt
      rust-analyzer

      # nokhwa
      libclang
      linuxHeaders
      stdenv.cc.libc_dev
    ];
  in {
    devShell.${system} = pkgs.mkShell {
      inherit buildInputs;
      RUST_BACKTRACE = 1;

      LD_LIBRARY_PATH = (lib.makeLibraryPath buildInputs);
      BINDGEN_EXTRA_CLANG_ARGS = "-I${pkgs.linuxHeaders}/include -I${pkgs.stdenv.cc.libc_dev}/include";
    };
  };
}

And my Cargo.toml:

[package]
name = "nokhwa-experiments"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies.nokhwa]
version = "0.9.4"
features = ["input-v4l"]
