Hello, I am trying to make a camera work on my Jetson Nano rev B01, running a Jetpack image that I downloaded from [this page](https://developer.nvidia.com/embedded/learn/get-started-jetson-nano-devkit#write) two days ago (I do not know how to find the Jetpack version, sorry). I have two different cameras: - A Raspberry Pi Camera Module V2 (CSI) - A LI-USB30-AR023ZWDR Camera Module from Leopard Imaging (USB 3.0) My goal is to use the USB Camera, and I am using the RasPi camera to try having a camera working. The cameras seems to be recognized: ```nohighlight $ ls /dev/video* /dev/video0 /dev/video1 $ v4l2-ctl --list-devices vi-output, imx219 7-0010 (platform:54080000.vi:0): /dev/video0 AR023ZWDR (usb-70090000.xusb-1.3): /dev/video1 ``` However I have trouble getting them to work. nvgstcapture-1.0 seems to work for the RasPi camera. I can capture images and open them, however, there is no preview. I have attached the output in the file nvgstcapture-csi.txt. It does not work at all for the USB camera: ```nohighlight $ nvgstcapture-1.0 --camsrc=0 --cap-dev-node=1 ** Message: 17:37:53.127: iterating capture loop .... ERROR on bus: by /GstPipeline:capture_native_pipeline/GstBin:cap_bin/GstV4l2Src:v4l2src0: Internal data stream error. debug info: gstbasesrc.c(3055): gst_base_src_loop (): /GstPipeline:capture_native_pipeline/GstBin:cap_bin/GstV4l2Src:v4l2src0: streaming stopped, reason not-negotiated (-4) ** Message: 17:37:53.180: Capture completed ** Message: 17:37:53.181: Camera application will now exit ``` I have also attached a dmesg log. I should note that the USB camera is working on three other computers, on multiple OS (Windows 10, Ubuntu 18 & 20) I have found multiple forum posts, without success. I never had a camera live preview working.

For your RPi v2 IMX219 connected to CSI0, for displaying to X window into GUI, you may just use : ```auto gst-launch-1.0 -v nvarguscamerasrc ! nvvidconv ! xvimagesink ``` For your USB cam being on /dev/video1, you may try: ```auto gst-launch-1.0 -v v4l2src device=/dev/video1 ! video/x-raw ! videoconvert ! xvimagesink ``` This might not work depending on your camera. If this doesn’t work, post the output of: ```auto v4l2-ctl -d1 --list-formats-ext ``` ---

Thank you for helping me! The first command for RPi works, thank you very much! The second one for USB did not, so here is the `--list-formats-ext` output: ```nohighlight ioctl: VIDIOC_ENUM_FMT Index : 0 Type : Video Capture Pixel Format: 'YUYV' Name : YUYV 4:2:2 Size: Discrete 1920x1080 Interval: Discrete 0.033s (30.000 fps) Size: Discrete 1280x720 Interval: Discrete 0.033s (30.000 fps) Size: Discrete 2304x1536 Interval: Discrete 0.045s (22.000 fps) ``` Also, the two cameras seems to be handled differently, e.g. I cannot get `cheese` to try using the RPi camera ---

Maybe cheese is no longer working on Jetsons (at least in R32.5). You may try specifying a native mode such as: ```auto gst-launch-1.0 -v v4l2src device=/dev/video1 ! video/x-raw,format=YUY2,width=1280,height=720,framerate=30/1 ! xvimagesink # Or gst-launch-1.0 -v v4l2src device=/dev/video1 io-mode=2 ! video/x-raw,format=YUY2,width=1280,height=720,framerate=30/1 ! xvimagesink ``` If it doesn’t work, you may try [this binary patch](https://forums.developer.nvidia.com/t/jetpack-4-5-nvv4l2h264enc-no-more-one-instance-with-opencv-4-5-2-segmentation-fault/181348/21). ---

Hi, Thank Honey Patouceul for sharing the binary. It is known that 3rdparty applications such as cheese do not work on Jetpack 4.5.1. Please apply the binary and give it a try. ---

Thank you again! Both commands work! No problem for cheese, I was only using it to test the cameras. Thanks for the information about 3rd party applications! Have a nice week-end! ---
