A Simple Example
```rust
use std::time::Duration;
use bevy::prelude::*;
use bevycapturemedia::{MediaCapture, BevyCapturePlugin};
pub fn spawncameras(
mut commands: Commands,
mut capture: MediaCapture,
) {
let cameraentity = commands
.spawn_bundle(Camera2dBundle::default())
.id();
// The tracking ID (1357) is arbitrary, but uniquely identifies this tracker
capture.start_tracking_camera(1357, camera_entity, Duration::from_secs(5));
}
pub fn takescreenshot(
input: Resreleased(KeyCode::RShift) {
// If you have many cameras, consider storing their IDs
// in a resource
capture.capture_png(1357);
}
}
fn main() {
app::new()
.addplugin(DefaultPlugins)
.addplugins(bevycapturemedia::BevyCapturePlugin)
.addstartupsystem(spawncameras)
.addsystem(take_screenshot);
}
```

I want to add a new format!
Yes! This is great! There is a small checklist that any new format will need to meet to be included:
- Encoding must happen in pure rust. No compiled C libraries, no bindings to other languages.
- The format must perform well for a web target - if there is a very good reason to circumvent this, the format may still be accepted.
- By default, the format and any dependencies must be optional and opt-in.
- No patent-encumbered or closed formats will be accepted unless there is a free and permissive license grant for this project and any end users.
