v4l2-ctl -d /dev/video19 --set-selection=target=crop,width=1920,height=1080 --set-fmt-video=width=1920,height=1080,pixelformat=NV12 --stream-mmap=3 --stream-to=mp.out --stream-count=1 --stream-poll
执行的是这个命令 用的debian10 执行后 读取文件 是全黑 摄像头是imx317

1. ps -aux | gerp ispserver确认ispserver进行有没有起来,ispserver没起来,系统没启动3A,获取到的图像会偏暗
2. 抓图命令增加--stream-skip=15参数,跳过15帧之后再抓图,有可能第一帧自动曝光还没开始调节,需要经过一些帧之后才能获取到合适曝光的图像。
3. 如果ispserver没起来,在执行第二步的前提下,拿手机闪光灯照摄像头,再抓图,把图像文件打包发出来看看。
