    执行编译出来的./video12 800 800 60 得到的图像。像是按照4:3拉伸得到的图像， 并不是裁剪出来的800 *800的正方形

        @nb 请问你使用的camera module型号，主板型号是什么？
        有没有配置ROI参数？

            @veye_xumm 主板是RK3588 ROI驱动里没有配置过

              参考我们这个demo，我看到你的代码中

              std::string v4l2_cmd = "media-ctl -d /dev/video0 --set-v4l2 '\"m00_b_mvcam 7-003b\":0[fmt:Y8_1X8/" + std::to_string(width) + "x" + std::to_string(height) + "@1/" + std::to_string(fps) + " field:none]'";

              -d /dev/video0似乎应该改为-d /dev/media0

                在video12.cpp里改成了-d /dev/media0， 出图还是会有拉伸的效果，
                附近上传的是rk3588的dmesg 打印。还有video12.cpp的应用程序。还有就是出图效果png文件，帮忙再分析看看是什么原因

                  用你们的python demo v4l2dev_2_opencv_show_grey.py出图也是一样的效果

                    @nb 我看你执行这两个程序都有报错的提示。
                    猜测可能你的板子跟我们例程的板子有所不同。具体而言就是是不是/dev/video0和/dev/media0对应着这个相机？
                    看现象就是ROI没有正确按照你想要的配置进去。你可以用i2c脚本直接读取参数的形式来确认这一点。

                    ./mv_mipi_i2c.sh -r -f roi -b your_i2c_bus_number

                      @veye_xumm 系统启动后 ，直接用python3 v4l2dev_2_opencv_show_grey.py --width=1440 --height=1088 --fps=60 这个来出图，不做任何ROI裁剪 ，得到的图像，也是有拉伸效果。 所以我觉得 应该不是 后期通过i2c配置ROI导致的。

                        @nb 相机本身并不具备单个方向缩放的能力，你可以尝试参考7.4.3或者7.4.4保存一个图片，然后查看一下。

                              raw8数据可以直接用这个播放器看，不需要转。另外你可以把原始数据文件压缩一下传上来我看看。

                                  你这个图片有一些莫名其妙的竖条纹，我觉得相机的输出和你的接收现在是不配套的。你执行

                                  ./yavta -c1 -Fy14-${WIDTH}x${HEIGHT}.raw --skip 0 -f Y8 -s ${WIDTH}x${HEIGHT} /dev/video0

                                  之前设置WIDTH或者HEIGHT等全局变量了吗？

                                      你的主板应该不是我用的ROC-RK3588S-PC吧？
                                      我怀疑是ROI配置没有配下去。
                                      你现在用这个命令读出来roi配置试试：

                                      ./mv_mipi_i2c.sh -r -f roi -b your_i2c_bus_number

                                        你之前提供的脚本是2字节读写的，应该不对, 我做了些调整，改正4字节读写了 2.png

                                            @veye_xumm 我有一个怀疑的点。是驱动里日志打印来看这里获取到最大值mvcam: mvcam_probe: max width 1456; max height 1088
                                            后 然后接着就是读取ROI， mvcam: mvcam_getroi:get roi(0,0,1440,1088)

                                            但是我并没有从驱动代码里找到 有设置ROI为14401088的地方，麻烦能告诉一下驱动里设置ROI为14401088的代码在哪里吗， 我想把驱动代码里设置ROI为1440*1088的代码给注释掉试试。
