An idiomatic cadeau to Rust

Idiomatic wrapper around Cadeau library, performance primitives and media foundation functions.

It’s possible to choose between dynamically loading the library at runtime by enabling the dlopen feature, or regular static / dynamic linkage at build-time. The API itself is identical except for a init function which must be called before using other API when dlopen feature is enabled.

use std::path::Path;

use cadeau::xmf::image::Image;
use cadeau::xmf::recorder::Recorder;

fn main() -> Result<(), Box<dyn std::error::Error>> {
  #[cfg(feature = "dlopen")]
  unsafe { cadeau::xmf::init("./libxmf.so")? };

  assert!(cadeau::xmf::is_init());

  let frame_path = Path::new("./frame.png");
  let frame = Image::load_file(&frame_path)?;

  let output_path = Path::new("./output.webm");

  let mut recorder = Recorder::builder(frame.width(), frame.height(), 10).start(&output_path)?;

  recorder.update_frame(frame.data(), 0, 0, frame.width(), frame.height(), frame.step())?;
  recorder.timeout();

  Ok(())
