CSI camera change RGB888 format to bayer format issue

channinglan · February 17, 2022, 1:47am

The architecture is CAMER → FPGA → Jetson Xavier AGX

FPGA output CSI
RGB888 format setting …

						mode_type = rgb;
						pixel_phase = rgb888;
						csi_pixel_bit_depth = 24;

video can be seen normally
gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw, format=(string)BGRA, width=(int)400, height=(int)400 ! videoconvert ! xvimagesink -ev

But modify CSI CAMER to make it output bayer format

blayer format setting

						mode_type = bayer;
						pixel_phase = bggr;
						csi_pixel_bit_depth = 10;

gst-launch-1.0 -vvv nvarguscamerasrc sensor-id=0 ! ‘video/x-raw(memory:NVMM), width=(int)400, height=(int)400, framerate=30/1, format=(string)NV12’ ! nvvidconv flip-method=0 ! nvoverlaysink -e

show error …

Looks like the devname in tegra-camera-platform{} didn’t match the driver name.
Have dump dtb to confirm it.

The devname need the same with v4l2-ctl --list-device like below, devname need the same with “ov5693 30-0036”

nvidia@nvidia-desktop:~$ v4l2-ctl --list-device
vi-output, ov5693 30-0036 (platform:15700000.vi:0):

video1 is ok…run rgb888 800x800 is ok

ShaneCCC · February 17, 2022, 4:28am

Check the devname in tegra-camera-platform{} in device tree.

channinglan · February 17, 2022, 6:04am

my dts
tegra194-camera-gen3.dtsi (19.5 KB)

devname = “gen3_a 0-001e”;
and
devname = “gen3_b 0-002e”;

ShaneCCC · February 17, 2022, 6:26am

Modify it to the devname to “gen3 0-001e” to match the driver report.(remove “_a” and “_b”)

The trace log tell didn’t receive any validate data from MIPI bus.
You may need to probe the sensor output signal to confirm it.

Try to reduce the initial time to try.

channinglan · February 21, 2022, 7:45am

1.Does this FPGA need long time initial to output data to MIPI?
… After changing the format to RGB888, it can be displayed normally,
There should be no problem with the FPGA initial time being too long

2.How to convert Bayer 10 raw data to bmp ??
The general conversion software is similar to bayer_bggr8 or bayer_bggr16le …

ShaneCCC · February 25, 2022, 4:05am

Do you mean tools to show the Bayer format? I used 7yuv.
Or Gstreamer element bayer2rgb.

channinglan · February 25, 2022, 5:49am

use v4l2-ctl command…
v4l2-ctl -d /dev/video0 --stream-mmap --stream-count=1 --stream-skip=3 --stream-to=test.raw

Need to convert to BMP file
The format is
mode_type = bayer;
pixel_phase = bggr;
csi_pixel_bit_depth = 10;
Can’t find a suitable conversion software. Do you have any suggestions??

So change the format and add the corresponding program
mode_type = bayer;
pixel_phase = bggr;
csi_pixel_bit_depth = 8;

v4l2-ctl -d /dev/video0 --list-formats-ext

ioctl: VIDIOC_ENUM_FMT

Pixel Format: ‘BA81’

Screenshot from 2022-02-25 13-37-40.bmp (2.3 MB)

The FPGA generates a pattern so that the data should be
Except for the first LINE, everything else is red
But the actual received data seems to have lost data

Originally should be 400x400
but each line will have a different number
Have you encountered similar problems??

ShaneCCC · March 1, 2022, 4:07am

Could you generate 640x480 to verify it again.

Thanks
