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 -
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
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.
