  1. Hi can someone help me in this issue I have overlay and camera connected to the device but issue says cannot open the camera index in my orange pi pc root@orangepipc:~/python# python3 capture_image.py [ WARN:0] global ../modules/videoio/src/cap_v4l.cpp (887) open VIDEOIO(V4L2:/dev/video1): can't open camera by index Traceback (most recent call last): File "capture_image.py", line 11, in <module> isWritten = cv2.imwrite('image-2.jpg', frame) cv2.error: OpenCV(4.2.0) ../modules/imgcodecs/src/loadsave.cpp:715: error: (-215:Assertion failed) !_img.empty() in function 'imwrite'

Hi @rreignier , @rdeyes and all I am using orange pi PC I have used the overlay with in my orange pi pc for camera OV5640 camera CSI interface "AVDD-supply = <&reg_vcc_af_csi>; DOVDD-supply = <&reg_vdd_1v5_csi>; DVDD-supply = <&reg_vcc_csi>;" overlay is successfull please find the attachment, root@orangepipc:~/python# media-ctl --device /dev/media1 --print-topology Media controller API version 5.10.21 Media device information ------------------------ driver sun6i-csi model Allwinner Video Capture Device serial bus info platform:1cb0000.camera hw revision 0x0 driver version 5.10.21 Device topology - entity 1: sun6i-csi (1 pad, 1 link) type Node subtype V4L flags 0 device node name /dev/video1 pad0: Sink <- "ov5640 1-003c":0 [ENABLED] - entity 5: ov5640 1-003c (1 pad, 1 link) type V4L2 subdev subtype Sensor flags 0 device node name /dev/v4l-subdev0 pad0: Source [fmt:UYVY8_2X8/640x480@1/30 field:none colorspace:srgb xfer:srgb ycbcr:601 quantization:full-range] -> "sun6i-csi":0 [ENABLED] after connecting the camera i2c2 detect command root@orangepipc:~# ls /proc/device-tree/soc/i2c@1c2b400/camera@3c/ AVDD-supply clock-names clocks compatible DOVDD-supply DVDD-supply name phandle pinctrl-0 pinctrl-names port powerdown-gpios reg reset-gpios root@orangepipc:~# cat /proc/device-tree/soc/i2c@1c2b400/reg | xxd 00000000: 01c2 b400 0000 0400 ........ root@orangepipc:~# cat /proc/device-tree/soc/i2c@1c2b400/status okayroot@orangepipc:~# ls /proc/device-tree/soc/i2c@1c2b400/ '#address-cells' camera@3c clocks compatible interrupts name phandle pinctrl-0 pinctrl-names reg resets '#size-cells' status root@orangepipc:~# ls /dev/i2c-* /dev/i2c-0 /dev/i2c-1 /dev/i2c-2 root@orangepipc:~# ls /sys/class/i2c-adapter/ i2c-0 i2c-1 i2c-2 root@orangepipc:~# ls -l /sys/class/i2c-adapter/i2c-*/of_node lrwxrwxrwx 1 root root 0 Apr 22 11:10 /sys/class/i2c-adapter/i2c-1/of_node -> ../../../../../firmware/devicetree/base/soc/i2c@1c2b400 lrwxrwxrwx 1 root root 0 Apr 22 11:10 /sys/class/i2c-adapter/i2c-2/of_node -> ../../../../../firmware/devicetree/base/soc/i2c@1f02400 root@orangepipc:~# i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- UU -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- root@orangepipc:~# i2cdetect -y 2 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- UU -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- camera is not powered in in my orange pi my user overlay for csi .

  3. I have fixed it by changing to armbian focal normal one which is direct download before I used EU version the problem is that thank you for the fase reply
  4. Hi, I have used the official armbian focal image for orange pi PC (https://www.armbian.com/orange-pi-pc/) The issue is in the armbian-config navigate to system -> Hardware you see nothing as shown below Please find the monitor log http://ix.io/2WQv
  5. Hi, you should try with all 3 commands for orange pi
  6. Hi @rreignier, How can I bulid openCV in C++ for armbian. I checked the architecture of my device root@nanopiduo2:~/C/overlays# dpkg --print-architecture armhf In openCV in the link I have 2 cmake 1.arm-gnueabi.toolchain.cmake 2.arm.toolchain.cmake https://github.com/opencv/opencv/tree/master/platforms/linux I am confused which one to use.

  8. Hi All, Has anybody tried to capture video stream using ffmpeg? I have installed ffmpeg by using root@nanopiduo2:~# sudo apt install ffmpeg As thy say in the link https://wiki.friendlyarm.com/wiki/index.php/NanoPi_Duo2 -The mjpg-streamer utility uses libjpeg to software-encode steam data. The Linux-4.14 based ROM currently doesn't support hardware-encoding. If you use a H3 boards with Linux-3.4 based ROM you can use the ffmpeg utility to hardware-encode stream data and this can greatly release CPU's resources and speed up encoding: Error: root@nanopiduo2:~# ffmpeg -t 30 -f v4l2 -channel 0 -video_size 1280x720 -i /dev/video1 -pix_fmt nv12 -r 30 ffmpeg version 4.2.4-1ubuntu0.1 Copyright (c) 2000-2020 the FFmpeg developers built with gcc 9 (Ubuntu 9.3.0-10ubuntu2) configuration: --prefix=/usr --extra-version=1ubuntu0.1 --toolchain=hardened --libdir=/usr/lib/arm-linux-gnueabihf --incdir=/usr/include/arm-linux-gnueabihf --arch=arm --enable-gpl --disable-stripping --enable-avresample --disable-filter=resample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libaom --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libcodec2 --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libjack --enable-libmp3lame --enable-libmysofa --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librsvg --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxml2 --enable-libxvid --enable-libzmq --enable-libzvbi --enable-lv2 --enable-omx --enable-openal --enable-opencl --enable-opengl --enable-sdl2 --enable-libdc1394 --enable-libdrm --enable-libiec61883 --enable-chromaprint --enable-frei0r --enable-libx264 --enable-shared libavutil 56. 31.100 / 56. 31.100 libavcodec 58. 54.100 / 58. 54.100 libavformat 58. 29.100 / 58. 29.100 libavdevice 58. 8.100 / 58. 8.100 libavfilter 7. 57.100 / 7. 57.100 libavresample 4. 0. 0 / 4. 0. 0 libswscale 5. 5.100 / 5. 5.100 libswresample 3. 5.100 / 3. 5.100 libpostproc 55. 5.100 / 55. 5.100 Trailing options were found on the commandline.

  14. Hi all, Thank you for the code. I have tried it in nano pi duo 2 with ov5640 in kernal version 5.10.21 armbian focal. can you give us the output for media-ctl --device /dev/media1 --print-topology media-ctl --device /dev/video0 --print-topology I have added the overlay by sudo armbian-add-overlay csi-ov5640.dts and did reboot my device (nano pi duo 2) my output for, root@nanopiduo2:~# ls /dev/ autofs loop3 rtc0 tty24 tty46 ttyS0 vcsa3 block loop4 shm tty25 tty47 ttyS1 vcsa4 btrfs-control loop5 snd tty26 tty48 ttyS2 vcsa5 bus loop6 stderr tty27 tty49 ttyS3 vcsa6 char loop7 stdin tty28 tty5 ttyS4 vcsu console loop-control stdout tty29 tty50 ttyS5 vcsu1 cpu_dma_latency mapper tty tty3 tty51 ttyS6 vcsu2 cuse media0 tty0 tty30 tty52 ttyS7 vcsu3 disk mem tty1 tty31 tty53 ubi_ctrl vcsu4 ecryptfs mmcblk0 tty10 tty32 tty54 uhid vcsu5 fd mmcblk0p1 tty11 tty33 tty55 uinput vcsu6 full mqueue tty12 tty34 tty56 uleds video0 fuse net tty13 tty35 tty57 urandom watchdog gpiochip0 null tty14 tty36 tty58 v4l watchdog0 gpiochip1 ppp tty15 tty37 tty59 vcs zero hwrng ptmx tty16 tty38 tty6 vcs1 zram0 initctl pts tty17 tty39 tty60 vcs2 zram1 input ram0 tty18 tty4 tty61 vcs3 zram2 kmem ram1 tty19 tty40 tty62 vcs4 kmsg ram2 tty2 tty41 tty63 vcs5 log ram3 tty20 tty42 tty7 vcs6 loop0 random tty21 tty43 tty8 vcsa loop1 rfkill tty22 tty44 tty9 vcsa1 loop2 rtc tty23 tty45 ttyGS0 vcsa2 here I have media0 and video0 so, I tried root@nanopiduo2:~# media-ctl --device /dev/media0 --set-v4l2 '"ov5640 1-003c":0[fmt:JPEG_1X8/1920x1080]' Unable to setup formats: Invalid argument (22) root@nanopiduo2:~# fswebcam -d /dev/video0 -r 1920x1080 -D 0 --jpeg 100 /tmp/test.jpg -bash: fswebcam: command not found can you also give me the I2C detect, i2cdetect -y 0 i2cdetect -y 1 i2cdetect -y 2 I found I2C 2 which is connect to camera is not working root@nanopiduo2:~# ls -l /sys/class/i2c-adapter/ total 0 I found my I2C2 is disable how can I enable? root@nanopiduo2:~# fdtget /boot/dtb/sun8i-h3-nanopi-duo2.dtb /soc/i2c@1c2b400 status disabled Thanks in advance
