+
+Steps to compile the "gst-nvvideo4linux2" sources natively:
+
+1) Install gstreamer related packages on target using the command:
+
+	sudo apt-get install libgstreamer1.0-dev \
+		gstreamer1.0-plugins-base \
+		gstreamer1.0-plugins-good \
+		libgstreamer-plugins-base1.0-dev \
+		libv4l-dev \
+		libegl1-mesa-dev
+
+2) Download and extract the package "gst-nvvideo4linux_src.tbz2" as follow:
+
+	tar -I lbzip2 -xvf gst-nvvideo4linux2_src.tbz2
+
+3) Run the following commands to build and install "libgstnvvideo4linux2.so":
+	make
+	make install
+	or
+	DEST_DIR=<dir> make install
+
+  Note: For Jetson, "make install" will copy library "libgstnvvideo4linux2.so"
+  into "/usr/lib/aarch64-linux-gnu/gstreamer-1.0" directory. For x86 platforms,
+  make install will copy the library "libgstnvvideo4linux2.so" into
+  /opt/nvidia/deepstream/deepstream-4.0/lib/gst-plugins
