将 VideoCompositor 中最后渲染的代码修改就可以解决

VideoCompositor.ciContext.render(image, to: outputPixels)

改为：

let colorSpace = CGColorSpace.init(name: CGColorSpace.sRGB) ?? CGColorSpaceCreateDeviceRGB()
        VideoCompositor.ciContext.render(image, to: outputPixels, bounds: image.extent, colorSpace: colorSpace)
