MediaPlayer3D
Experimental 3D media playback framework and demo applications
Experimental cross-platform 3D media playback framework and a collection of demonstration applications built with Qt 6.11.1. The project is organized around a reusable Core library and several proof-of-concept frontends showcasing different Qt user interface technologies: - Qt Widgets - Qt Quick - Qt Quick 3D - Qt Quick 3D XR Qt Multimedia provides a solid foundation for video decoding and playback control. However, its standard presentation pipeline is primarily focused on monoscopic 2D video output. This project explores how that foundation can be extended to support stereoscopic and panoramic media rendering in both 2D and 3D environments, including desktop and virtual reality use cases. The project is intended to: - Gain practical experience with the Qt Rendering Hardware Interface (QRhi). - Provide a performant and reusable multimedia infrastructure for 3D environments. - Experiment with media player UI design in VR -
