Answer 1

I had the same problem. The solution from @Mindshifter worked for me, but you can have a look here for more comments (and I've posted a similar solution there too):

Answer 2

In CameraSourcePreview.java comment this lines of code:

    if (childHeight > layoutHeight) {
        childHeight = layoutHeight;
        childWidth = (int)(((float) layoutHeight / (float) height) * width);
    }
