Edit images and video with Swift concurrency, powered by Metal.

Hi, I build for creators.

I code in Swift & Metal, building apps for the creation of video and graphics. I have a background in projection mapping and visual programming.

asyncgraphics's Issues

Cocoapods support?

Refactor SIMD3 to Point3D

Make Graph's from Graphic's

We have two types: Graphic & Graph
The graphics are the source of the graphs.
I want to make versions of all graphics as graphs.

Polygon Example:
Graphic: polygon(...)
Graphs: AGPolygon & AGRoundedPolygon

Please feel free to submit a PR of a Graph implementation of a Graphic (one PR per graphic).

Video Playback Example throws Error

The example you give here throws errors on the line return GraphicVideoPlayer(url: url, options: options):

1: 'async' call in a function that does not support concurrency.
2: Call can throw, but it is not marked with 'try' and the error is not handled

I could fix error # 2 but struggle with fixing the first error.

I'm on Xcode 15.2, macOS 13.6.4.

Capture session on background thread

Getting a warning for CameraController line 73

   captureSession.startRunning()

-[AVCaptureSession startRunning] should be called from background thread. Calling it on the main thread can lead to UI unresponsiveness

`levels` effect not consistent between video & camera source

When processing frames from Graphic.playVideo with the levels effect, and setting the gamma uniform in the levels shader to values greater than 1, the image does not get inverted. But when you obtain frames from the camera, the image does get inverted.

This is just a small issue, but swapping between video/camera sources might be common during development to prototype effects. So it might be worth looking into parity between the two frame sources.

Example:

let processed = try await frame.levels(
            brightness: 2,
            darkness: 0.6,
            contrast: 0.2,
            gamma: 1.2 
        )
