How Can I Rotate Image And Video If It Was Captured In Landscape Mode?

I have an ImageView and VideoView on my screen. My Activity is always in a portrait mode (and i can't rotate it because of another elements). How can i rotate image/video if it

Solution 1:

public Bitmap rotateBitmap(Bitmap source, float angle) {
        Matrix matrix = new Matrix();
        // Perform matrix rotations/mirrors depending on camera that took the photo
        if (cameraCurrentID == Camera.CameraInfo.CAMERA_FACING_FRONT) {
            float[] mirrorY = { -1, 0, 0, 0, 1, 0, 0, 0, 1};
            Matrix matrixMirrorY = new Matrix();
            matrixMirrorY.setValues(mirrorY);
            matrix.postConcat(matrixMirrorY);
        }
        matrix.postRotate(angle);
        return Bitmap.createBitmap(source, 0, 0, source.getWidth(),
                source.getHeight(), matrix, false);
    }
