How to take a screenshot in media3 ExoPlayer

Question

I need to take a screenshot in ExoPlayer, the root view of which is PlayerView. enter image description here

Answer 1

I figured it out and found a simple solution to how to get a Bitmap from the view, partly this is the answer to my question

val bitmap = videoView.drawToBitmap()

UPDATED 27.04.2023

DrawToBitmap() in my case produced a black screenshot. I haven't found anything better than specifying surface_type as surfaceview

app:surface_type="surface_view"

Then in the code I convert the player view to a surface view

binding.apply {
val videViewSurface = videoView.videoSurfaceView as SurfaceView
ScreenshotUtils.takeScreenshotWithPixelCopy(videViewSurface) { bitmap ->...}
}

Then I use Pixel Copy to create the final bitmap

fun takeScreenshotWithPixelCopy(videoView: SurfaceView, callback: (Bitmap?) -> Unit) {
            val bitmap: Bitmap = Bitmap.createBitmap(
                videoView.width,
                videoView.height,
                Bitmap.Config.ARGB_8888
            )
            try {
                val handlerThread = HandlerThread("PixelCopier")
                handlerThread.start()
                PixelCopy.request(
                    videoView, bitmap,
                    { copyResult ->
                        if (copyResult == PixelCopy.SUCCESS) {
                            callback(bitmap)
                        }
                        handlerThread.quitSafely()
                    },
                    Handler(handlerThread.looper)
                )
            } catch (e: IllegalArgumentException) {
                callback(null)
                e.printStackTrace()
            }
        }
