播放.bin视频文件运行缓慢。如何更快地执行？

Question

我的代码如下：

image_name = filename    
f_uyvy = open(image_name, "rb")
image_out = array.array('B')
image_out = Image.new("RGB", (width, height),"rgb(85%,85%,85%)")
pix = image_out.load()
#YUV is converted into RGB and stored into numpy
    video = np.array(image_out) 
    cv2.imshow('video', video)
    if cv2.waitKey(25) & 0xFF == ord('q'):
        exit()
print "File Ended"

它正在工作，但很慢。如何更快地显示帧？
