My code:
use opencv::prelude::*;
use opencv::{highgui, videoio, Result};
fn main() -> Result<()> {
let window = "video capture";
highgui::named_window(window, highgui::WINDOW_AUTOSIZE)?;
let mut cam = videoio::VideoCapture::new(0, videoio::CAP_ANY)?;
let opened = videoio::VideoCapture::is_opened(&cam)?;
if !opened {
panic!("Unable to open default camera!");
}
loop {
let mut frame = Mat::default();
cam.read(&mut frame)?;
if frame.size()?.width > 0 {
highgui::imshow(window, &frame)?;
}
let key = highgui::wait_key(10)?;
if key > 0 && key != 255 {
break;
}
}
// Очистка
highgui::destroy_all_windows()?;
Ok(())
}
