Gstreamer plugin for Jetson Nano for stabilizing video input.

GstNvStabilize

This is gstreamer plugin to stabilize video input on nvidia devices. Tested on jetson nano.

Steps to compile the gst-nvstabilize 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
   

2. Run the following commands to build and install libgstnvstabilize.so:

    cd "gst-nvstabilize"
    make
    make install
    or
    DEST_DIR=<dir> make install
   

Note: make install will copy library libgstnvstabilize.so into /usr/lib/aarch64-linux-gnu/gstreamer-1.0 directory.
