      换了好几个pi5,os64,换了两个IMX264,RAW12 Y12P,打包的数据会来回跳,正常的时候是两个字节加打包字节,很快会跳成一个字节加打包字节再加另一个字节,还有时候会跳成其他的情况。如下图所示,测试图片,拆成四副图拼接,分别是两个字节和打包拆分的字节。

      t1.png

      系统是6.18.34+rpt-rpi-2712
      6.12驱动编译安装

      用QT V4L2也可以看到这种跳动,只不过是近似2×2排布。

      最关键两IMX264情况还不一样,一个只跳一次,但是不来回跳,一个来回跳,但是画面会回绕移动几个像素。

      刚才又试了IMX178好像没问题。

        不好意思,看到有点晚了。
        请确认一下相机的版本号,可以通过mv_mipi_i2c_new.sh进行读取。

          @golden0514 另外,请问你使用的ffc cable长度?能否拍一个硬件连接图的照片我看看。

          raw8格式,使用我们veye_viewer客户端,是否有图像错误的问题?

          我这边可以用这种方式来预览,尝试重现?

            这个是硬件连接图,使用官方的线,还试过自己买的线,也用v2转接板和官方22pin线试过,都有问题。

            这个是参数和版本查询结果
            setting.jpg
            raw8和raw10都工作正常,没有问题。这个是qt v4l2采集的raw8图像。
            raw8.jpg
            raw12时用qt v4l2也可以查看是否正常。这个是正常的图像,两个数据在上面,打包数据在下面,v4l2好像按照彩色图像解包。
            normal.jpg
            这个是异常图像,正常数据跑到下面去了,打包数据在上面。

            连续显示的话可以看到图像的跳转,甚至是来回跳转,不过我测试的两个摄像头有一个只跳一次,有一个来回跳转。

              @golden0514 不好意思,再多问一句,你用的roi参数以及fps参数是多少?

                @veye_xumm roi就是最大值,2464*2056
                fps也是最大值,不过试过不同fps,最短的fps 1Hz也回出现这个问题。
