    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 用这个命令./yavta -c1 -Fy8-${1440}x${1088}.raw --skip 0 -f Y8 -s ${WIDTH}x${HEIGHT} /dev/video0 抓到的raw图像然后转成png后，看到的还是会有拉伸效果

          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。

            @veye_xumm 【有道云笔记】抓图测试raw 文件
            https://note.youdao.com/s/J6oOs0K3

            你好 ，论坛 不支持上传raw文件，我直接把./yavta -c1 -Fy14-${WIDTH}x${HEIGHT}.raw --skip 0 -f Y8 -s ${WIDTH}x${HEIGHT} /dev/video0 用这个命令抓到的文件，上传到自己的有道云笔记上了，然后上面是分享出来的链接。

              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？

                配置了的 写了个脚本 ，会先执行 source ./set-wh.sh 然后再echo打印看下 ，配置的有没有成功

                  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

                  参考：

                    这里得到的结果是0x05a0(1440) 0x0440(1088)

                    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。

                                有没有可能是硬件的问题？你试过ROC-RK3588S-PC主板上的结果吗？

                                  @veye_xumm 我们这边 没有ROC-RK3588S-PC 这个硬件，
                                  我觉得 可以再往前面排查一步， 就是模组 出图Max width是1536 Height是1088

                                  然后不知道哪里给设置ROI 设置成了1440 和1088 我想知道 这一步是在哪里设置的。 会不会就是这一步设置成1440 *1088的时候 被拉伸了。

                                    @nb 其实用mv_mipi_i2c.sh这个脚本，就是直接读取和写camera寄存器的，是最底层也最直接的操作。
                                    驱动层面只是封装了对寄存器的读写而已。
                                    但是你说你的板子上mv_mipi_i2c.sh不行，我觉得很奇怪。

                                    这里得到的结果是0x05a0(1440) 0x0440(1088)

                                    根据你自己的修改过的脚本，相机端读到的roi数据是跟3588板子上的驱动中的值是一致的。

                                    因此我才怀疑是不是硬件的问题。
