Hello, It took me long before I have figured these things on my own. May be this will be useful for someone.

I have only implemented it for SKIA as following: const NativeImageSkia* skiaImage = image->nativeImageForCurrentFrame(); SkBitmap::Config config = skiaImage->config(); // this contains pixel format > > 1.
