Incorrect colors

[br0kenpixel]

I'm using the following code to capture an image and save it to file:

fn capture_webcam() {
    let index = CameraIndex::Index(0);
    let requested = RequestedFormat::new::<RgbFormat>(RequestedFormatType::None);
    let mut camera = Camera::new(index, requested).unwrap();
    println!("{}", camera.info().human_name());

    camera.open_stream().expect("Permission denied");
    let frame = camera.frame().unwrap();
    camera.stop_stream().unwrap();
    let decoded = frame.decode_image::<RgbFormat>().unwrap();

    decoded.save("img.png").unwrap();
    println!("Captured webcam");
}

The result is a pink-ish image:

I tried:

• Changing RgbFormat to other formats
• Changing image file format from png to jpeg

Also, according to the documentation, camera.open_stream() should be called internally by camera.frame(), however, deleting the camera.open_stream().expect("Permission denied"); line makes camera.frame() hang forever.

This could be due to #78. I tested the 0.10.3 code and it's still reporting as NV12 despite being successfully decoded as YUV422. I'm not sure, though, because decode_image() fails with "bad input buffer size". Just a lead, maybe?
