用的是 ipc 固件吗？RkLunch-stop.sh 关掉应用才行。应用占用了摄像头节点

timeout 是因为没开 dbserver 和 ispserver
并且要指定对应的 video 节点才可以。详细教程见：https://wiki.t-firefly.com/zh_CN/CORE-1126-JD4/Devices.html#mipi-csi
/oem/RkLunch-stop.sh
/oem/usr/bin/dbserver &
/usr/bin/ispserver &

#开启 dbserver 和 ispserver 之后就可以进行抓图了
v4l2-ctl -d /dev/video19
–set-fmt-video=width=1920,height=1080,pixelformat=NV12
–stream-mmap=3
–stream-skip=3
–stream-to=/tmp/cif.out
–stream-count=1
–stream-poll

/dev/video19 不能抓raw 图。
你有没有试过如何抓HDR raw图。
