Steps to compile the "gst-nvv4l2camera" 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-nvv4l2camera_src.tbz2" as follow:
tar -I lbzip2 -xvf gst-nvv4l2camera_src.tbz2
3) Run the following commands to build and install "libgstnvv4l2camerasrc.so":
make
make install
or
DEST_DIR=<dir> make install
Note: "make install" will copy library "libgstnvv4l2camerasrc.so"
into "/usr/lib/aarch64-linux-gnu/gstreamer-1.0" directory.
