MV-MIPI-SC130M在树莓派4上最大帧率只有22
-
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。
