RAW_MIPI_SC535M设置ROI
-
您好，
我使用的相机是RAW_MIPI_SC535M，开发板是RK3588S-PC，系统是firefly5.10，我在使用v4l2的VIDIOC_CROPCAP指令获取该相机的裁切能力时，相机反馈不支持裁切，使用VIDIOC_S_CROP直接设置ROI时相机也无法成功设置。请问我应该使用什么方式持久化设置相机的ROI呢？
ps：我使用的开发语言是c++，框架是Qt5.12.5 -

三种方法：
1.命令行
参考part7.4.1
https://wiki.veye.cc/index.php/MV_Camera_on_Firfly_Boards/zh#.E4.BD.BF.E7.94.A8media-ctl.E9.85.8D.E7.BD.AE.E5.9B.BE.E5.83.8F.E6.A0.BC.E5.BC.8F
2. C语言代码
参考7.4.4中yavta的源码。
3. 如果你应用中roi只想配置一次，相机保存，后面不需要配置。也可以使用：
mv_mipi_i2c.sh配置一下roi，然后读取确认。之后，执行paramsave命令，将参数保存到摄像机里面。
这样，每次上电的时候，驱动能自动读取相机当前roi值。你的程序就不需要再次配置了。 -
