OV5647 Camera module used in LINUX SDK

D3
1

I use a OV5647 module in LINUX SDK on D3G board. I use v4l2-ctl to grab a YUV but the picture seems not correct. I try to use gst-launcher instruction as github Doc described, but failed.

Please help check is the LINUX SDK OK for OV5647 module testing ?

Hello,

Could you please let us know which camera module you are using and the image (FW) version that was flashed to the D3-G via FWDN?

Please share the exact commands you used for camera capture and for running the gst-launch pipeline.
Please also share the error logs generated when executing the commands.

The capture must be performed in UYVY format.
Below is an example capture command:

v4l2-ctl --device 0 --set-fmt-video width=1640,height=1232,pixelformat=UYVY --stream-mmap --stream-to ./1640x1232.UYVY --stream-count 5

Thank you.

I flash the image D3-G Release Note - v1.3.0, and dmesg display that OV5647 is probed:

root@d3-g-topst-main:~# dmesg | grep ov5647

According to:

Single Board Computer/G Model/D3-G/Available Applications/Use Cases with the D3-G Board.md

I use command:

gst-launch-1.0 -v v4l2src device=/dev/video0 io-mode=2 ! video/x-raw,format=NV12,width=1920,height=1280,framerate=30/1 ! videoconvert ! waylandsink fullscreen=true

But the result log:

root@d3-g-topst-main:~# gst-launch-1.0 v4l2src device=/dev/video0 io-mode=2 ! video/x-raw,format=NV12,width=1920,height=1280,framerate=30/1 ! videoconvert ! e

The default image does not include v4l2-ctl command.

How can I continue to test camera?

Are you running this from a terminal connected via the UART debug port?

Before executing the gst command, please run:

export XDG_RUNTIME_DIR=/run/user/root

Then, please try running the gst command again.

gst-launch-1.0 v4l2src device=/dev/video0 io-mode=2 ! video/x-raw,format=NV12,width=1280,height=720,framerate=30/1 ! videoconvert ! waylandsink fullscreen=true

It appears that you have flashed a Yocto image.

The v4l2-ctl command is not available because the v4l-utils package is not included in the Yocto build.

Please copy the attached file to the board and install it using dpkg -i, then proceed with testing.

v4l-utils_1.22.1-r0_arm64.deb

Thank you.

Old SDK is working OK, but after my building SDK1.3, even download/fwdn prebuilt image 1.3, the camera preview is FAIL(same HW old sdk is OK), log:

gst-error.txt (85.8 KB)

Thanks, we see that when login use root/root, the camera working OK.

Thanks.
