I want to capture each preview frame in camera.
manipulate it, then display in the view.
I kown a interface named "Camera.PreviewCallback" can return each preview frame. But it starts capture only when "startPreview()" is called. However, "startPreview()" causes each frame display before i edit it.
I want to edit the frame before it is displayed. How can i do?
I'am a beginner of English and android...
Look forward your answer. Thank you very much.
