Google Vision works better with the preview frames coming from CameraEx
Yes ! I know and use it now with FullHD frames it works OK each ~0.25 sec.
But there is a need to have max camera settings control via Camera2 API. But it's slower now (just getting FullHD frame bitmap is ~0.45 sec, without Vision work), and not usable as freezing. Camera1 code does not freeze visually at all.
So, question is to move fully to Camera2 API from Camera v.1 API, without any troubles.
Maybe CameraEx2 can provide the byte data for Vision? It seems, it may be, but the same slow, anyway conversion from the tv View.
