Camera::frame_texture returns wgpu::TextureHandle instead of wgpu::Texture about nokhwa HOT 4 CLOSED

The nannou crates's implementation creates a different Texture object per nannou documentation. As far as a pure Wgpu workload is concerned, it is working as intended.
Creating your own implementation of that method as a function should be trivial - just replace the wgpu to nannou::wgpu

from nokhwa.

So after digging up a lil bit (and some help from the nannou community), there is a better option than reimplementing the Camera::frame_texture method. Although this is a nannou thing, I'll post it here in case anyone runs into the same problem.

The idea is to capture a frame, transform the image into a DynamicImage and create a nannou::Texture using the from_image method.

let img = camera.frame().unwrap();
let dyn_img = image::DynamicImage::ImageRgb8(img);
let tex = nannou::wgpu::Texture::from_image((device, queue), &dyn_img);

from nokhwa.

I will add a frame_nannou_texture for nannou users.

Given that nannou is organized in a modular manner, I think it would be a better idea to write a wrapper and implement the features stated in nannou-org/nannou#464. Something like nannou_camera or nannou_webcam.

I can work on this.
