Key Features:
-
Overlay Qt GUIs onto Live Video
Seamlessly render QML-based graphics into a GStreamer pipeline—great for real-time streaming or display. -
GPU-Accelerated (OpenGL)
Offloads rendering to the GPU for maximum performance and minimal CPU load. -
Streaming Support
Record or stream video with the overlay intact—ideal for remote dashboards or video telemetry systems. -
Modular QML Design
Update overlays dynamically without recompiling the plugin. -
Native GStreamer Element
Use like any standard GStreamer filter—insert into pipelines with full control.
Example Use Case:
A robotic monitoring system uses a Jetson Orin device with four camera inputs. Each stream is annotated with real-time telemetry data, such as battery level, motor temperature, and GPS coordinates—rendered with QML-based widgets on top of the video feed. With GstQtOverlay, the system streams this annotated video over RTSP, letting operators view live status overlays remotely, without needing a separate dashboard.
Limitations:
-
Remote user input (mouse/keyboard) is not supported in this version through Qt events, it can be implemented manually. Visual overlays are output-only and designed for status display and feedback, not interaction (unless you implement the state machine that control the widget).
Use Cases:
-
Smart camera UIs and video telemetry
-
Live AI overlays for bounding boxes, inference metrics, or system stats
-
Industrial monitoring with visual event markers
-
Robotics or AR with on-screen annotations
-
Multimedia streaming with embedded QML visualizations

Customer Reviews
"As a side note: just to let you know, I'm really happy to be working with RidgeRun in general. It's pretty clear that you tell it like you see it, and know what you do and don't know; it's really refreshing. That's super rare on these kinds of technical engagements when everyone seems to either want to claim expertise they don't have, or are so cautious they are don't actually say anything useful"
