v4l2-ctl下载链接:https://download.csdn.net/download/qq_38312843/12916684
将附件v4l2-ctl推到板子/vendor/bin/目录，然后输入如下命令：
v4l2-ctl --verbose -d /dev/videoX --set-fmt-video=width=640,height=480,pixelformat='MJPG' --stream-mmap=4 --set-selection=target=crop,flags=0,top=0,left=0,width=640,height=480
videoX 可以通过 grep -H ‘’ /sys/class/video4linux/video*/name 查看。 使用
v4l2-ctl -d /dev/videoX --list-formats-ext 可查看摄像头支持的格式及帧率信息
px30_android-8.1\device\rockchip\rk3326\rk3326_m2g\media_profiles_default.xml
在media_profiles_V1_0.xml中删掉720x480的制式，以下分辨率都支持，可以在media_profiles_V1_0.xml中自己添加上。
(640x480) (160x120) (320x240) (352x288) (800x600) (1280x720)
(1280x1024)
