==== Check system status ====
The steps to verify the setup before testing Gstreamer pipelines are as follows:
1. Run the following commands to check the Gstreamer-1.0 version.
<code>$ gst-inspect-1.0 --version</code>
<code>gst-inspect-1.0 version 1.14.4</code>
<code>GStreamer 1.14.4</code>
Note: Make sure that VEYE-MIPI-290/327 is connected and the required driversare loaded.
During booting, the module drivers for VEYE-MIPI-290/327 will be loaded automatically in the Jetson Nano™ development kit.
2. Run the following command to confirm whether the camera is initialized.
<code>dmesg | grep “veye327”</code>
The output message appears as shown below.
<code>subdev veye327 6-003b bound</code>
The output message indicates that the camera is initialized properly.
3. Run the following command to check the presence of video node.
<u><code>ls /dev/video0</code></u>
The output message appears as shown below.
<code>video0</code>

*Preview FHD(HW accelerated)
<code>gst-launch-1.0 v4l2src ! "video/x-raw,format=(string)UYVY, width=(int)1920, height=(int)1080" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)I420" ! nvoverlaysink sync=false</code>
*Record FHD in H.264 format to a video file（HW accelerated）
<code>gst-launch-1.0 v4l2src ! "video/x-raw,format=(string)UYVY, width=(int)1920, height=(int)1080" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)I420" ! omxh264enc qp-range=20,20:20,20:-1,-1 ! matroskamux ! queue ! filesink location=videoname.mkv</code>
*Playback of saved video file (HW accelerated）
<code>gst-launch-1.0 filesrc location=videoname.mkv ! matroskademux ! h264parse ! omxh264dec ! nvoverlaysink</code>
*Capturing FHD still image
<code>gst-launch-1.0 v4l2src num-buffers=1 ! "video/x-raw,format=(string)UYVY, width=(int)1920, height=(int)1080" ! jpegenc ! filesink location=jpgname.jpg</code>
