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.

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;

        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.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)

        gst-launch-1.0 v4l2src ! ...

Bring up the camera (/dev/video0) with 1280x720 by Gstreamer pipeline:

DISPLAY=:0 gst-launch-1.0 v4l2src device=/dev/video0 ! \
"video/x-raw, format=(string)UYVY, width=(int)1280, height=(int)720" ! \
nvvidconv ! nv3dsink sync=false

Troubleshooting

1. 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.

2. 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
