nokhwa

Nokhwa(녹화): Korean word meaning "to record".

A Simple-to-use, cross-platform Rust Webcam Capture Library

Example

// set up the Camera
let mut camera = Camera::new(
    0, // index
    Some(CameraFormat::new_from(640, 480, FrameFormat::MJPEG, 30)), // format
    CaptureAPIBackend::AUTO, // what backend to use (let nokhwa decide for itself)
)
.unwrap();
// open stream
camera.open_stream().unwrap();
loop {
    let frame = camera.get_frame().unwrap();
    println!("{}, {}", frame.width(), frame.height());
}

They can be found in the examples folder.

Feature

The default feature includes nothing. Anything starting with input-* is a feature that enables the specific backend.

input-* features:

• input-v4l: Enables the Video4Linux backend (linux)
• input-uvc: Enables the libuvc backend (cross-platform)

Conversely, anything that starts with output-* controls a feature that controls the output of something (usually a frame from the camera)

output-* features:

• output-wgpu: Copies a frame directly into a wgpu texture.

You many want to pick and choose to reduce bloat.
