      @xiaoxun 你按照我们的wiki取图吧。现在摄像机由于要支持任意位置的roi,所以驱动跟VLC并不能很好兼容的。

      好的,您的意思是出图前要设置ROI 吗? 另外我下载的驱动代码是支持IMX178 的吗?另外我好像用命令设置IMX178 其他尺寸的时候会提示我设置尺寸参数失败,是这款摄像头只支持 3088*2064吗,应为我从设备信息列表里边也没有看到其他的分辨率支持

                  试一下执行此命令之前,先配置好正确的roi:

                  v4l2-ctl --set-selection=target=crop,top=0,left=0,width=2816,height=2164

                    是在用之前必须要配置好 ROI 吗?

                      @xiaoxun 是的。因为set-format并不能提供配置roi的全部功能,所以在驱动实现中通过set selection接口做了roi配置。

                        imx78 树莓派
                        export DISPLAY=:0

                        v4l2-ctl --set-selection=target=crop,top=0,left=0,width=1920,height=1080
                        v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=UYVY

                        gst-launch-1.0 v4l2src device=/dev/video0 ! "video/x-raw,format=(string)UYVY, width=(int)1920, height=(int)1080, framerate=(fraction)22/1" ! v4l2convert ! "vi
                        deo/x-raw,format=(string)NV12" ! autovideosink sync=false -v

                        在屏幕上边并没有显示,是哪操作的不正确吗?

                            我觉得你的操作没有问题。现在这个pipeline是作为一种调试手段,其中用到的数据格式转换采用的是软件运算的方式,所以效率比较低。
                            我测试了一下,改成640*480还是比较流畅的。
                            你使用的树莓派型号是什么?

                                      你试试opencv这个 6.6.5.2:
