      使用的型号是veye imx265那一款
      驱动已经打上.
      使用 v4l2指令能够成功抓图.
      但使用opencv出的视频只有一部分.
      请问你们推荐的最优抓取视频帧的方式是什么?
      以及如果我想同时连接多个i相机, 驱动是否支持, 还是需要做修改

        你看看代码,是不是宽高设置的不是全画幅?

        驱动层面就是提供了v4l2数据接口而已。应用层你根据自己需求去选择就行。

        驱动分两部分,一部分是C语言编译成ko的,一般来说不需要动。另一部分是dtb,也就是设备树,这个需要根据你的硬件进行调整。

          @veye_xumm I2C设备寻址的时候 地址是相机给的吧, 你们的同一型号的相机里面的设备地址是一样的么?

              @veye_xumm 如果设备地址是一样的, 那我i2c总线上无法寻到不同的设备吧. 那我在一路i2c上挂载多个设备的时候 怎么使用呢? 相机出厂的时候能改i2c设备地址么

                @geniusdo 一般来说,每一个mipi口都会有一个单独的i2c总线与之对应。
