      (1)我試著使用 git clone https://github.com/veyeimaging/raspberrypi.git 提供的 ./veye_raspipreview -t -1 指令去preview

      不過沒有出現畫面，我裝的driver是veyecam2m，請問要做甚麼調整?

      这个是lagcy模式，需要uninstall驱动，打开lagcy camera支持才行。

      (2)請問我能直接使用libcamera來preview嗎?

      libcamera本质上是一个isp的框架，我们的相机本身带了isp功能。所以不需要，现在也不支持libcamera。

      (3)我用gstreamer和vlc來preview在30FPS的情況下畫面會卡頓是正常的嗎?您那邊畫面是順暢的嗎?

      这个主要原因是大量的使用cpu做软件的内存拷贝导致的。 还是建议你用lagcy mode。

            @kuo 这个是树莓派的一种机制。其实并没有识别，cpu端通过mmal库，访问到gpu端，gpu端访问的camera。所以整体都是在应用层。

                    @kuo 两种方法，一种是你的后端程序去统计AF统计信息。 另一种就是直接用手动聚焦镜头，不用AF功能。

                      @veye_xumm AF统计信息該如何取得? 我想取得AF edge 值看他何時是清新何時是模糊

                        @kuo 之前说过了，摄像机没有统计这个参数的功能。
