V4l2-compliance several errors

Robotics & Edge Computing Jetson & Embedded Systems Jetson TX2
1

Hi,
I am working with a jetson tx2 on an auvidea J120 carrier board. I am currently customizing the ov5693 driver and the device tree for it to work with our own sensor. I did the necessary in the device tree to have the following format : MEDIA_BUS_FMT_UYVY8_1X16.

mode_type = “yuv”;
pixel_phase = “uyvy”;
csi_pixel_bit_depth = “16”;

I get the following from v4l2-ctl --list-formats-ext:

ioctl: VIDIOC_ENUM_FMT
	Type: Video Capture

	[0]: 'UYVY' (UYVY 4:2:2)
		Size: Discrete 2592x1944
			Interval: Discrete 0.033s (30.000 fps)
		Size: Discrete 2592x1458

		Size: Discrete 1280x720
			Interval: Discrete 0.008s (120.000 fps)

			Interval: Discrete 0.033s (30.000 fps)
		Size: Discrete 2592x1944
			Interval: Discrete 0.033s (30.000 fps)

I already commented out the UYVY format I am not using in the vi4_formats.h to avoid duplicate format 59565955 (UYVY) in test VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS.

When I do v4l2-compliance -d /dev/video0 I have the following errors :

Can you help me understand where errors are coming from ?
Thank you for your help

The root cause by the duplicate resolution report. That’s the defeat of current camera framework design.

Hi Shane, thank you for your reply. Just for clarification I am using l4t R32.4.4. I’ve removed the duplicate resolutions. Now I have :

ioctl: VIDIOC_ENUM_FMT
	Type: Video Capture

	[0]: 'UYVY' (UYVY 4:2:2)
		Size: Discrete 2592x1944
			Interval: Discrete 0.033s (30.000 fps)

			Interval: Discrete 0.033s (30.000 fps)
		Size: Discrete 1280x720
			Interval: Discrete 0.008s (120.000 fps)

But I still have 2 errors from compliance test as you can see below:

Do you know why VIDIOC_G/S_PARM and VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF could fail ?
For VIDIOC_G/S_PARM, I don’t think it is a framerate problem because we manage it by ourself with the sensor.

The reference sensor driver imx274have the same failed I think you can ignore it.
