Bring up Camera​

TechNexion VizionViewer​

VizionViewer™

Gstreamer​

If you succeed in initialing the camera, you can follow the steps to open the camera.

  1. Check the supported resolutions:

    $ gst-device-monitor-1.0 Video/Source
    Device found:

            name  : vi-output, tevs 9-0039
            class : Video/Source

  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

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 occurred the errors nvbufsurftransform: Could not get EGL display connection by rununing 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
