Chitra is an OpenGL-based media viewer and rendering engine designed for layered rendering of images, videos, and 3D models. It supports real-time playback and visualization, making it suitable for multimedia applications. The project integrates FFmpeg for video decoding and muxing, and utilizes Dear ImGui for GUI widgets. Chitra is currently a work in progress, with ongoing development to enhance its capabilities.
-
OpenGL-Based video rendering pipeline Implements OpenGL rendering pipeline for video playback which compiles & links GLSL vertex and fragment shaders at runtime; loads decoded frames into OpenGL textures and renders in time synchronized manner.
-
FFmpeg Integration Uses FFmpeg for hardware accelarated codecs for video decoding and demuxing capabilities. Support for NVENC codecs is currently under testing.
-
Layered Rendering System Supports rendering architecture with support for layered scene composition and isolation of render passes. See
layersclass for more details. -
Input Event Dispatcher Input Events Dispatcher system to handle and route keyboard, mouse, and controller events to the stacked input layers.
-
ImGui GUI Integration Uses ImGui for dynamic and interactive GUI widgets and docking system, ideal for real-time debugging and user tools.
-
Doxygen Integration Supports HTML and PDF documentation generation via Doxygen, ensuring maintainable and accessible code documentation.
-
Cross platform Cmake build system & Precompiled Headers (PCH) Utilizes precompiled headers to significantly reduce compile times and improve developer productivity.
