====== 使用gstreamer预览UYVY格式图像 ======
<code>export DISPLAY=:0</code>
<code>export DISPLAY=:0</code>
UYVY模式支持的最大宽度为2880，使用如下命令可以进行实时预览。

====== 使用opencv预览GREY格式图像 ======
<code>sudo apt install python3-opencv</code>
* 我们提供了一个简单的[https://github.com/veyeimaging/nvidia_jetson_veye_bsp/tree/master/samples/opencv/raw_camera sample]实现此功能：
<code>python ./v4l2dev_2_opencv_show_grey.py --roix 0 --roiy 0 --width 640 --height 480 --fps 30</code>
