How to Change GStreamer Element Property for Full-Screen Playback

When working with multimedia applications, providing a full-screen experience is often a critical feature. If you're using GStreamer on a Wayland platform, you might be wondering how to adjust the Waylandsink property to enable full-screen playback. In this guide, we’ll go over the steps to configure GStreamer to achieve this, as well as alternate methods to go full screen without modifying the Waylandsink property.

Understanding GStreamer and Waylandsink

GStreamer is a powerful multimedia framework that simplifies the handling of audio and video streams. One of its elements, Waylandsink, interfaces with the Wayland display server to present graphics. The fullscreen property of Waylandsink allows you to toggle between windowed and full-screen modes.

Problem Statement

You’re trying to make your GStreamer application play media in full-screen mode. The Waylandsink element contains a fullscreen property that you need to modify. The question arises: How do you change this property, or is there an alternative way to achieve full-screen playback without modifying it?

Solution: Changing the Fullscreen Property

Method 1: Command Line Approach

For quick tests and setups, you can launch your GStreamer pipeline directly from the command line. Here’s how you can set the fullscreen property to TRUE:

This command initializes a GStreamer pipeline that specifies a source file, decodes it, applies a filter, and renders it in full-screen mode.

Method 2: Programmatic Approach

If you’re developing a C application that utilizes GStreamer, you’ll want to configure the fullscreen property in your code. Here’s a comprehensive example that outlines the steps you need to follow:

Step 1: Initialize GStreamer

First, you need to initialize the GStreamer library.
