rk3399+ov13850 通过gstreamer获取4k失败，是什么问题？
rk3399+ov13850 通过gstreamer 能获取2k的视频流，但是gstreamer获取4k失败，尝试过以下设置，但是无效，请帮忙看看，谢谢！
media-ctl -d /dev/media0 —set-v4l2 ‘“m00_b_ov13850 2-0010”:0[fmt:SBGGR10_1X10/4224x3136]’
gstreamer报错信息如下：
[root@rk3399:/app]# gst-launch-1.0 v v4l2src device=/dev/video0 ! video/x-raw,f
ormat=NV12,width=4096,height=3096 ! waylandsink

可以先用v4l2-ctl测试下出流是否正常，如：
v4l2-ctl -d /dev/video0 —set-fmt-video=width=4096,height=3096,pixelformat=NV12 —stream-mmap=3 —stream-to=/tmp/nv12.raw
可以查阅相关文档docs\Linux\Camera
经过以下设置，能采集4kraw图，但是采集出的4k raw 图是crop的，视角只有2k的左上角1/4。请问这是什么原因?
采集命令：
v4l2-ctl -d /dev/video0 —set-fmt-video=width=4224,height=3136,pixelformat=NV12 —stream-mmap=3 —stream-skip=30 —stream-to=/app/cif.out —stream-count=1 —stream-poll
