Imx566 sensor configuration image width issue

[asfsdgag]

hello:
I use custom card in orin nx 16G，SDK version is r35.4.1. Default sensor width is 2856, I want use Hardware ROI function,data sheet CSI data format is as follows：

The height can be adjusted， but The width is not acceptable，I must set sensor out width:2856, read bytesperline 2880. Otherwise, errors may occur that only the first few items of content for the first application buffer can be obtained . I use original v4l2 linux api. The ultimate goal is to ensure that the values of FINFO_HWIDTH and VOPB_VBLK_HWIDTH are consistent with the width of the ROI.

thank you!

Dynamic change the output width?

[asfsdgag]

yes，After each modification of the ROI, I use VIDIOC_QUERYBUF to remap buff and retrieve the stream

[ShaneCCC]

Current don’t support dynamic width.

hello:
I an not use tegra drives component, only use base V4L2 obtain sensor RAW in VI ,not use ISP，Really can’t it be done? Or is there a modified case? This is a hard requirement for me.

You can check the vi5_fops.c to modify to match your request.

Thanks
