Introduction

This is an attempt at building a church presentation application in Qt/QML. QML provides a very powerful and easy declarative way of creating a UI so it should also be a very simple method of creating on screen slides and presentations. This experiment is to see how difficult it is to rebuild these applications in QML as opposed to other more complicated systems. After digging through the source code of OpenLP, I discovered they are essentially creating a web server and rendering a webpage onto the screen to show slides. This felt like a waste of resources and added complexity when something so simple and useful as QML exists.

Features (planned are in parentheses)

• Presents songs lyrics with image and video backgrounds
• Use MPV as a rendering system for videos
• Simple song creation with a powerful text parser - Almost fully finished
• (Present Slides)
• (Custom slide builder)

MPV

You will need MPV installed in order to use this. All videos run through it. This, however, enables us to make videos work very well and with a lot of control and since it uses ffmpeg underneath, nearly any codec regardless of underlying system. This prevents the need for the user to install other codecs to work with Windows or MacOS. It also means a much easier control system and the potential to stream web content as well without downloading first.

Build and Run

First get the source code

Then into the root directory.

cd church-presenter

Then build.

cmake -B build/ . && make --dir build/

Then run.

./build/bin/presenter
