Using TechNexion Pre-built modules

Preparation

We recommend following the user manual from platform vendors to set up the system. After that, you can follow the below method to install TechNexion Cameras Driver.

1. Download pre-built modules.

   $ wget https://download.technexion.com/demo_software/EVK/NVIDIA/AFE-R750/OrinNX/pre-built-modules/latest/JP61/tn_camera_modules_jp61.tar.gz

2. Uncompress the modules.

   $ tar -xf tn_camera_modules_jp61.tar.gz

3. Run installation script.

   $ cd tn_camera_modules_<built_time>/
   $ sudo ./tn_install.sh

4. After you agree to continue the installation, select the camera PHY mode. The module will be installed to the system.

   $ sudo ./tn_install.sh

Bring up Camera

TechNexion VizionViewer

VizionViewer™

Gstreamer

If you successfully initialize the camera, you can follow the steps to open the camera.

1. Check the supported resolutions:

   $ gst-device-monitor-1.0 Video/Source
   Probing devices...
   
   Device found:
   
           name  : vi-output, tevs 9-0039
           class : Video/Source
           caps  : video/x-raw, format=UYVY, width=640, height=480, framerate=60/1
                   video/x-raw, format=UYVY, width=1280, height=720, framerate=60/1
                   video/x-raw, format=UYVY, width=1280, height=800, framerate=60/1
                   video/x-raw, format=NV16, width=640, height=480, framerate=60/1
                   video/x-raw, format=NV16, width=1280, height=720, framerate=60/1
                   video/x-raw, format=NV16, width=1280, height=800, framerate=60/1
           properties:
                   object.path = v4l2:/dev/video0
                   device.api = v4l2
                   media.class = Video/Source
                   api.v4l2.path = /dev/video0
                   api.v4l2.cap.driver = tegra-video
                   api.v4l2.cap.card = "vi-output\,\ tevs\ 9-0039"
                   api.v4l2.cap.bus_info = platform:tegra-capture-vi:0
   
   ...
   

2. Use the Gstreamer pipeline to launch a 1280x720 resolution camera (/dev/video0) via the CPU:

   $ DISPLAY=:0 gst-launch-1.0 v4l2src device=/dev/video0 ! \
   "video/x-raw, format=UYVY, width=1280, height=720" ! xvimagesink sync=false

3. Use the Gstreamer pipeline to launch a 1280x720 resolution camera (/dev/video0) via the GPU:

   $ DISPLAY=:0 gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! \
   "video/x-raw(memory:NVMM), format=UYVY, width=1280, height=720" ! \
   nvvidconv ! nv3dsink sync=false

---

Troubleshooting

Cannot find cameras

If you cannot bring up the cameras, you can check if the video device does exist.

$ ls /dev/video*  # List all video devices
/dev/video0  /dev/video1  /dev/video2  /dev/video3

If you cannot see the devices, you should check if the drivers have been probed.

Occur Error: Could not get EGL display connection

If you encounter the error nvbufsurftransform: Could not get EGL display connection by running the Gstreamer command, you can modify the parameter DISPLAY by the command:

# Check and Set environment parameter for 'DISPLAY'
$ export DISPLAY=$(w| tr -s ' '| cut -d ' ' -f 3 | grep :)

# Run Gstreamer pipeline
$ gst-launch-1.0 v4l2src device=/dev/video0 ! \
"video/x-raw, format=UYVY, width=1280, height=720" ! xvimagesink sync=false

no element "nvv4l2camerasrc"

If you encounter the following error:

WARNING: erroneous pipeline: no element "nvv4l2camerasrc"

This means your system is missing some NVIDIA GPU-related plug-in tools. You have to install some NVIDIA plug-in tools for Gstreamer.

$ sudo apt update && apt depends nvidia-jetpack | awk '{print $2}' | uniq | xargs -I {} bash -c "sudo apt -o Dpkg::Options::="--force-confold" -y install {} ; sudo apt clean"
