      输入v4l2-ctl -L后,显示frame_rate 0x00981904 (int) : min=0 max=22 step=1 default=22 value=22 flags=volatile, execute-on-write。

      输入v4l2-ctl --set-fmt-video=width=1280,height=1024,pixelformat=GREY --stream-mmap --stream-count=-1 --stream-to=/dev/null后,显示<<<<<<<<<<<<<<<<<<<<<<<< 22.00 fps。

      请问这是为什么?

        建议使用这个命令获取当前roi情况下最大的帧率。
        http://wiki.veye.cc/index.php/Mv_mipi_i2c.sh_user_guide#maxfps
        然后用这个命令修改
        http://wiki.veye.cc/index.php/Mv_mipi_i2c.sh_user_guide#maxfps

        当然了,用v4l2-ctl修改帧率也可以的。 不用理会list出来的max value。

          @veye_xumm 我记得文档里是推荐用v4l2的,所以实际上要用哪个呀?

            @veye_xumm 以及想问下这个文件在哪,enable_i2c_vc.sh?

            建议在wiki这部分写明对应文件在哪里,会比较方便。

              enable_i2c_vc

              不好意思忘了上传这个文件,你从github再更新一下吧,已经传上去了。
