Dear Jerry,
Thanks for your reply, in the dts my setting is 0x02d0(720), it’s so strange that is changed to 0x02cf.
I attached the dts file as below.
active_w = "1280";
active_h = "720";
pixel_t = "bayer_uyvy";
readout_orientation = "90";
line_length = "3960";
root@tegra-ubuntu:/home/nvidia# v4l2-ctl --list-formats-ext -d /dev/video0
ioctl: VIDIOC_ENUM_FMT
Index : 0
Type : Video Capture
Pixel Format: 'UYVY'
Name : UYVY 4:2:2
Size: Discrete 1280x720
Interval: Discrete 0.033s (30.000 fps)
Size: Discrete 1920x1080
Interval: Discrete 0.033s (30.000 fps)
This attached file is the dts setting of my project
