gst-distance's Introduction

gst-distance

Is a simple social distancing plugin for Nvidia DeepStream. It was written prior to the advent of nvanalytics and feature it's own metadata format.

Requirements:

Hardware

  • An Nvidia dGPU supported by DeepStream (GeForce works, but is not officially supported)

(or)

  • A Nvidia Tegra board of your preference.

Software

  • DeepStream 5.0 (obtaining this on any platform is harder than it should be)

  • Other software: on Ubuntu / Debian / Linux for Tegra:

    sudo apt install \
    libglib2.0-dev \
    libgstreamer-plugins-base1.0-dev \
    libgstreamer1.0-dev \
    ninja-build \
    python3-pip
pip3 install --upgrade meson

Building

git clone --branch (branch) (repo url)
cd (repo folder)
mkdir build && cd build
meson (options) ..
ninja test
(sudo) ninja install

A systemwide install is not necessary if you tell meson to configure a --prefix like ~/.local and set GST_PLUGIN_PATH accordingly. ninja uninstall can be used to uninstall.

gst-distance's Issues

ninja: build stopped: subcommand failed

I was running the "ninja test" command and halfway it failed and there was an error "collect2: error: ld returned 1 exit status". This is the output after running the command.
