Setup

gstreamer1-0 (Ubuntu 24.04)

sudo apt-get install -y libgstreamer1.0-dev libgstreamer-plugins-base1.0-0 libgstreamer-plugins-base1.0-dev libgstreamer-plugins-bad1.0-0 libgstreamer-plugins-bad1.0-dev gstreamer1.0-plugins-ugly gstreamer1.0-tools gstreamer1.0-pipewire gstreamer1.0-qt6 gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-libcamera gstreamer1.0-plugins-bad gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-libav gstreamer1.0-vaapi

QuaZip

Clone the QuaZip repo from https://github.com/stachenov/quazip/

git clone https://github.com/stachenov/quazip.git
cd quazip

To build QuaZip for Qt6, you will need to point it to the platform folder of your Qt6 installation. If you installed Qt6 through the Qt Maintenance Tool it will default to ~/Qt/ if run as a user or /opt/Qt/ if installed with sudo. The example assumes a root install.

cmake -B build -DCMAKE_PREFIX_PATH="/opt/Qt/6.8.0/gcc_64/lib/cmake/Qt6/" -DQUAZIP_QT_MAJOR_VERSION=6
cmake --build build --config Release
sudo cmake --install build
sudo cp /usr/local/lib/libquazip* /usr/lib

DAWidgets

Follow the build/installation instructions located at https://github.com/DigitalArtifex/DAWidgets

This is a widgets library that can also be used in your version of QtCreator.

Building/Running FLO

  • Clone Flo
git clone https://github.com/DigitalArtifex/Flo.git
  • Setup Build Directory
cd Flo/
mkdir -p build/release
cd build/release
  • Run qt-cmake for the target version to configure the project

  • Build
cmake --build ./

It is important to note that FLO uses QtMultimedia to process webcam streams. While QtMultimedia defaults to FFMPEG, there are several known issues that can occur while using this backend. If you have any issues (i.e. system lockups, scan lines etc) it may be necessary to specify the native backend for your system. For example, on Linux the native backend is gstreamer and therefore would set the Media Backend option in System Settings to GStreamer
