// Các bạn có thể thay đổi giá trị các biến môi trường ở đây:
var radius = 240; // Độ rộng vòng xoay
var autoRotate = true; // Tự động xoay hay không
var rotateSpeed = -60; // đơn vị: giây/vòng. thời gian để xoay hết 1 vòng, dấu trừ để xoay ngược lại
var imgWidth = 120; // độ rộng ảnh (tính theo px)
var imgHeight = 170; // độ cao ảnh (tính theo px)


/*
        CHÚ Ý:
            + imgWidth, imgHeight sẽ dùng được cho cả video -> <video> cũng sẽ được thu nhỏ cho bằng <img>
            + nếu imgWidth, imgHeight đủ nhỏ, có thể <video> sẽ không hiện nút play/pause
