Prevent flipping of the front facing camera

Question

I\'m attempting to access the raw feed of android\'s front facing camera. By default, the front facing camera\'s preview is flipped horizontally so users can see themselves

Answer 1

If you want to use a front-facing camera for barcode scanning you can use TextureView and apply a transformation matrix to it. When the texture is updated you can read the image data and use that.

See https://github.com/hadders/camera-reverse

Specifically from MainActivity.java

mCamera.setDisplayOrientation(90);
Matrix matrix = new Matrix();
matrix.setScale(-1, 1);
matrix.postTranslate(width, 0);
mTextureView.setTransform(matrix);
