tip

You should reboot the device after installation.

Method 3 - Build drivers from source code​

Please follow the guide to build camera driver modules.

Bring up Camera by 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 9-0048
            class : Video/Source
            caps  : video/x-raw, format=(string)UYVY, width=(int)1280, height=(int)800, framerate=(fraction)60/1;
                    video/x-raw, format=(string)UYVY, width=(int)1280, height=(int)720, framerate=(fraction)60/1;
                    video/x-raw, format=(string)UYVY, width=(int)640, height=(int)480, framerate=(fraction)60/1;
                    video/x-raw, format=(string)UYVY, width=(int)1280, height=(int)800, framerate=(fraction)60/1;
                    video/x-raw, format=(string)UYVY, width=(int)1280, height=(int)720, framerate=(fraction)60/1;
                    video/x-raw, format=(string)UYVY, width=(int)640, height=(int)480, framerate=(fraction)60/1;
                    video/x-raw, format=(string)NV16, width=(int)1280, height=(int)800, framerate=(fraction)60/1;
                    video/x-raw, format=(string)NV16, width=(int)1280, height=(int)720, framerate=(fraction)60/1;
                    video/x-raw, format=(string)NV16, width=(int)640, height=(int)480, framerate=(fraction)60/1;
            properties:
                    udev-probed = true
                    device.bus_path = platform-tegra-capture-vi
                    sysfs.path = /sys/devices/platform/tegra-capture-vi/video4linux/video0
                    device.subsystem = video4linux
                    device.product.name = "vi-output\,\ tevs\ 9-003e"
                    device.capabilities = :capture:
                    device.api = v4l2
                    device.path = /dev/video0
                    v4l2.device.driver = tegra-video
                    v4l2.device.card = "vi-output\,\ tevs\ 9-003e"
                    v4l2.device.bus_info = platform:tegra-capture-vi:1
                    v4l2.device.version = 330344 (0x00050a68)
                    v4l2.device.capabilities = 2216689665 (0x84200001)
                    v4l2.device.device_caps = 69206017 (0x04200001)
            gst-launch-1.0 v4l2src ! ...

    ...

  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=(string)UYVY, width=(int)1280, height=(int)720" ! \
nvvidconv ! nv3dsink sync=false
