hello,
We have been trying to initialize your module in 1080p and 720p but its failing , either for lack of ram or incorrect frame size, please help us with the correct settings when we are opening a video in opencv. i would like to record 1080p video on it , failing that atleast 720p
but only video we could record was at 640x480 , please also suggest the libraries that we need to install to make this happen

this repository is for testing purposes only. the camera is working or not working. How to install the camera is not written. dts not working.

Hello

I got a bananaPI M2 Zero and got the recommended camera module.
Trying to follow this manual, downloaded the image, it is working.

when trying to init the camera i get this:
pi@banana:$ sudo media-ctl --device /dev/media1 --set-v4l2 '"ov5640 2-003c":0[fmt:YUYV8_2X8/1280x720]'
Failed to enumerate /dev/media1 (-2)
pi@banana:$ sudo media-ctl --device /dev/media1 --set-v4l2 '"ov5640 2-003c":0[fmt:YUYV8_2X8/640x480]'
Failed to enumerate /dev/media1 (-2)
pi@banana:~$

I activated all io of the board (i2c etc') no help.

From DMESG:
pi@banana:$ dmesg | grep capture -a3 -n5

so, would like help in getting it to work.

Thank you.

after turning off the monitor overnight, when the monitor was powered back on the display settings somehow changed from the default 720 to a much higher resolution with lots of flickering

boots into login screen, but keyboard and mouse are not recognized (work in ubuntu)
cursor stops blinking after a few seconds...

** work well --> CamLive.py with 640*480
** work well --> gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw, width=640, height=480, framerate=30/1 ! videoconvert ! autovideosink

I changed set with

sudo media-ctl --device /dev/media1 --set-v4l2 '"ov5640 2-003c":0[fmt:YUYV8_2X8/1280x720@1/15]'

** do not work --> CamLive.py
** work well --> gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw, width=1280, height=720, framerate=15/1 ! videoconvert ! autovideosink

how can I change resolution without error in CamLive.py ?

Hello @Qengineering

Thank you for great work to provide image with open cv +ov 5640. Job that u did is really fundamental. But if it is possible I want to get instructions to get working ov5640 and opencv from fresh image. your image based of full system(+ desktop) and I would like to have some lightweight solution based on server image of (armbian/ubuntu/debian whatever is suitable for that).

I see that this board really wild , there a lack of info in the internet how to get things right.

I found A good article of your site how to compile opencv and it is really good guide. but csi camera makes me struggling for a week.
Best regards

First of all I initialized media device to be as v4l2 device with the following command:

sudo media-ctl --device /dev/media1 --set-v4l2 '"ov5640 2-003c":0[fmt:YUYV8_2X8/640x480]'

Command succeed, media-ctl has the following output

pi@banana:~$ media-ctl -p -d /dev/media1

/dev/video1 also is been created, but unfortunately I can't see device with v4l2-ctl

Due to dmesg I have the register error:

pi@banana:~$ dmesg | grep ov5640

Camera seems to be strangely initialized on the bus, without 100% correct address 0x3c

pi@banana:~$ sudo i2cdetect -y 2

Finally:

• what should I try to get image from camera?
• if I make aptitude update with upgrade the csi device gets out from the bus

Does the mediapipe library work on m2 zero?

i don't know is this all good....

but when it comes to actual using of camera - it says something about "pipeline error, can not open pipeline..." (i can paste it here tomorrow)

i tried python app, from code-block, even downloaded gvcuview app, and vlc. Zero success :-\ and i lost like 6h today on that...
