A Rust library for high-quality screen capture that leverages native OS APIs for optimal performance!

1. macOS: ScreenCaptureKit
2. Windows: Windows.Graphics.Capture
3. Linux: Pipewire

---

features

1. Cross-platform across Windows, Mac and Linux!
2. Checks for support and recording permissions.
3. Query list of captureable targets (displays and windows).
4. Exclude certain targets from being captured.

contributing

We found most of Rust's tooling around screen capture either very outdated, non-performant or platform-specific. This project is our attempt to change that. Contributions, PRs and Issues are most welcome!

If you want to contribute code, here's a quick primer:

1. Clone the repo and run it with cargo run.
2. Explore the API and library code in lib.rs.
3. Platform-specific code lives in the win, mac and linux modules.
4. The main.rs is a small program that "consumes" the library, for easy testing.

usage

use scap::{
    capturer::{Point, Area, Size, Capturer, Options},
    frame::Frame,
};

fn main() {
    // Check if the platform is supported
    if !scap::is_supported() {
        println!("❌ Platform not supported");
        return;
    }

    // Check if we have permission to capture screen
    // If we don't, request it.
    if !scap::has_permission() {
        println!("❌ Permission not granted. Requesting permission...");
        if !scap::request_permission() {
            println!("❌ Permission denied");
            return;
        }
    }

    // Get recording targets
    let targets = scap::get_all_targets();
    println!("Targets: {:?}", targets);

    // All your displays and windows are targets
    // You can filter this and capture the one you need.

    // Create Options
    let options = Options {
        fps: 60,
        target: None, // None captures the primary display
        show_cursor: true,
        show_highlight: true,
        excluded_targets: None,
        output_type: scap::frame::FrameType::BGRAFrame,
        output_resolution: scap::capturer::Resolution::_720p,
        source_rect: Some(Area {
            origin: Point { x: 0.0, y: 0.0 },
            size: Size {
                width: 2000.0,
                height: 1000.0,
            },
        }),
        ..Default::default()
    };

    // Create Capturer
    let mut capturer = Capturer::new(options);

    // Start Capture
    capturer.start_capture();

    let mut input = String::new();
    std::io::stdin().read_line(&mut input).unwrap();

    // Stop Capture
    capturer.stop_capture();
}
