All black image on OSX - Githubissues

salamanders commented 2 months ago

I'm trying for the first time on OSX, and getting an all-black image. Macbook M1 Pro, Sonoma (14.5)

// Mac OSX
Webcam.setDriver(NativeDriver())
Webcam.getWebcams().forEach { webcam ->
    println(webcam)
    println(" ${webcam.viewSizes.joinToString { "${it.size.width}x${it.size.height}" }}")
}
val webcam = Webcam.getDefault()
webcam.open()
repeat(20) {
   // warm up, or allow auto-levels
    webcam.image
}
val img = webcam.image
println("Image: ${img.width}x${img.height}")
ImageIO.write(img, "PNG", File("hello-world.png"))
webcam.close()

Not sure what can be wrong, does the readme example work correctly? https://github.com/eduramiba/webcam-capture-driver-native?tab=readme-ov-file#simple-example-with-javafx
