+Steps to compile the "gst-plugins-nv-video-sinks" sources:
+
+1) Install gstreamer related packages using the command:
+
+	sudo apt-get install gstreamer1.0-tools gstreamer1.0-alsa \
+		gstreamer1.0-plugins-base gstreamer1.0-plugins-good \
+		gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly \
+		gstreamer1.0-libav libgstreamer1.0-dev \
+		libgstreamer-plugins-base1.0-dev libegl1-mesa-dev
+
+2) Install CUDA Runtime 10.0+
+
+3) Extract the package "libgstnvvideosinks_src.tbz2" as follow:
+
+	tar xvjf libgstnvvideosinks_src.tbz2`
+
+4) cd "gst-plugins-nv-video-sinks"
+
+5) Export the appropriate CUDA_VER using - "export CUDA_VER=<cuda-version>"
+
+5) run "make" to create "libgstnvvideosinks.so"
+
+6) run "sudo make install" to install "libgstnvvideosinks.so" in
+   "/usr/lib/aarch64-linux-gnu/gstreamer-1.0".
+
+7) run "make install DEST_DIR=<location>" to install at different <location>.
