Crop camera preview for TextureView

Question

I have a TextureView with a fixed width and height and I want to show a camera preview inside of it. I need to crop the camera preview so that it doesn\'t look stretched ins

Answer 1

you could manipulate the byte[] data from onPreview().

I think you'll have to:

• put it in an Bitmap
• do the cropping in the Bitmap
• do a little stretching/resizing
• and pass the Bitmap to your SurfaceView

This is not a very performant way. Maybe you can manipulate the byte[] directly, but you will have to deal with picture formats like NV21.
