GStreamer Fast Text/Graphics Overlay
GStreamer Fast Text & Graphics Overlay – Lightweight CPU-Based Video Annotation RidgeRun’s Fast GStreamer Overlay plugin (emboverlay) is a lightweight, CPU-based GStreamer element for overlaying text, time/date, and logos or images on top of video streams or still frames. Designed for performance-constrained embedded systems, this plugin delivers real-time visual annotations without requiring GPU or OpenGL support—making it perfect for headless or minimal SoC environments. Whether you’re branding a live stream, timestamping a recording, or labeling output for later analysis, emboverlaygives you the essentials for fast, efficient video overlays. Key Features: CPU-Only RenderingPerfect for platforms without GPU support or floating-point acceleration. Overlay Support Dynamic or static text (e.g., status, labels) Timestamps and date/time PNG logos or icons Frame count or simple diagnostics Highly ConfigurableCustomize font size, color, background transparency, image position, scaling, and more. Real-Time ReadyDesigned for minimal latency, ideal for live streaming and edge AI pipelines. Example Use Case: An industrial inspection camera running on an NXP i.MX8 platform uses emboverlay to stamp a timestamp and production batch ID onto each video frame. The output is recorded for traceability and streamed to a remote dashboard—without requiring a GPU or additional software layers.
