This page provides a guide to build and install GstInference

Dependencies

System Dependencies

GstInference has the following system dependencies:

• pkg-config
• gtk-doc-tools
• libgstreamer1.0-dev
• libgstreamer-plugins-base1.0-dev
• gstreamer1.0-tools
• gstreamer1.0-plugins-good
• gstreamer1.0-libav
• opencv 3.3.1*

Also, GstInference makes use of the Meson build system.

Note: OpenCV is only needed if you wish to build the overlay elements.

Linux

In Debian based systems, you may install the dependencies with the following command:

sudo apt-get install -y python3 python3-pip python3-setuptools python3-wheel ninja-build pkg-config gtk-doc-tools libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev  gstreamer1.0-tools gstreamer1.0-plugins-good gstreamer1.0-libav libopencv-dev

Then, use pip3 to install the latest version of Meson directly from its repository.

sudo -H pip3 install git+https://github.com/mesonbuild/meson.git

R2Inference

To build GstInference you need to install R2Inference.

To install R2Inference please check R2Inference Build Instructions

Build Plugin

Linux

Note: If you are using Edge TPU backend with Google Coral the /usr/local/lib directory is not included by default in the linking path, hence we need to include it before building.

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/

export LD_LIBRARY_PATH=/usr/local/lib/x86_64-linux-gnu:$LD_LIBRARY_PATH

git clone https://github.com/RidgeRun/gst-inference.git
cd gst-inference
meson build --prefix /usr
ninja -C build
ninja -C build test
sudo ninja -C build install

Note: If you are building GstInference in the Coral Dev Kit consider using ninja -C build -j 1 if you have troubles related to memory consumption.

Yocto

GstInference is available at Ridgerun's meta-layer, please check our recipes here. Actually, only i.MX8 platforms are supported with Yocto.

First, create a Yocto environment for i.MX8, this i.MX8 dedicated wiki has more information to setup up a Yocto environment.

i.MX8 Yocto guide here.

In your Yocto sources folder, run the following command

git clone https://github.com/RidgeRun/meta-ridgerun.git

Enable RidgeRun's meta-layer in your conf/bblayers.conf file by adding the following line.

  ${BSPDIR}/sources/meta-ridgerun \

Enable Prebuilt-TensorFlow, R2Inference and GstInference in your conf/local.conf.

  IMAGE_INSTALL_append = "prebuilt-tensorflow r2inference gst-inference"

Finally, build your desired image, the previous steps added GstInference and its requirements into your Yocto image.

Verify Installation

The plugin installation can be verified by running:

gst-inspect-1.0 inference

In case of any error, please contact support@ridgerun.com with the following output, modify path according to your architecture:

gst-inspect-1.0 /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstinference.so
