#3.1 | Rotate camera preview to Portrait Android OpenCV Camera SOLUTION | java | openCV 4.6.0

If I modify deliverAndDrawFrame function and when i try to touch on frames and get touched x and y position I'm getting wrong values not the exact one. Any solution for this

Hi, for those having the same problem as me with the line : canvas.drawBitmap(mCacheBitmap, matrix, null); the solution is this
//Matrix matrix = new Matrix();
android.graphics.Matrix matrix = new Matrix();

thank you. My original code has a if (mScale != 0) statement. I left it commented and it worked just copying the fix from StackOverflow. Yours videos are very instructive thank you I'm going to start a road lane detection app now
