                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？

                                    @xiaoxun 奇怪，我这边没问题啊。
                                    你试试opencv这个 6.6.5.2：
