A Rust library for high-quality screen capture that leverages native OS APIs for optimal performance!
1. macOS: [ScreenCaptureKit](https://developer.apple.com/documentation/screencapturekit)
2. Windows: [Windows.Graphics.Capture](https://learn.microsoft.com/en-us/uwp/api/windows.graphics.capture?view=winrt-22621)
3. Linux: [Pipewire](https://pipewire.org)
---
## 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We found most of Rust's tooling around screen capture either very outdated, non-performant or platform-specific.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](./src/lib.rs).
3. Platform-specific code lives in the `win`, `mac` and `linux` modules.
4. The [main.rs](./src/main.rs) is a small program that "consumes" the library, for easy testing.
## Usage
```rust
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();
}
```
