怎么设置dm8127用dcc抓取一帧？

但是抓取raw的图像是正常的

你网页里面看的到正常的图像吗

嗯，从web看到的图像都是正常的，我从代码里看到是设置yuv420sp-uv的格式；
而且从dcc抓取的raw也是没问题，至少是有图像的；
但是抓取yuv后，用yuvplayer放就是这种情况；
不知道什么原因，我看了linker的代码，是从调用这个函数FVID2_control获取的数据，这个函数应该是汇编在m3vpss上实现的吧，我还没往下追，汇编不懂了。
我这个情况是dcc设置问题，还是目标板的配置问题？ 请帮我分析一下，谢谢

TI和appro的代码我没动，是rdk3.5的，sensor用的ar0331，这个跟这个dcc抓取yuv有关系吗？
总感觉在m3vpss对raw向yuv处理的时候是不是需要注意配置？
或者dcc使用有注意的方法？
另：：：我打开yuv看了0x0-0x8b80字节数据是0x80对yuv文件来说正常吗（而且每张都是）？

大师，请点拨一二

刚刚询问了一位仁兄，他说image应该是1952x1080，我试过，问题得不到解决

这是图像尺寸没有设定好。
你把YUV数据的pitch打印出来。

hi，我的打印信息是[m3vpss ] Input Channel CH0 of 1952 x 1112, pitch = (1984, 1984) [0,0][PROGRESSIVE] [7] ...，这个有什么问题吗？我对这个不太懂，
如果需要调整在哪个模块中调整？
我用messageQ从m3vpss得到的buffer大小直接就是1920*1080*3/2的大小
谢谢

这个的调整是不是位于mcfw层面的？app层没有发现对这个的设置

以下是vpss上的获取yuv部分，看源代码是直接从一个接口取得一个buffer，没有区分y和uv，源代码注掉了uv的部分，还没弄懂其底层如何实现，故不敢妄加揣测
