GstPTZR – GPU-Accelerated Digital Pan, Tilt, Zoom & Rotate for GStreamer
GstPTZR is a GStreamer plugin developed by RidgeRun to emulate Pan, Tilt, Zoom, and Rotate (PTZR) camera functionality using OpenGL-accelerated digital transformations. This allows you to simulate physical camera movement over a static video frame—ideal for embedded systems, robotics, and surveillance applications that need dynamic framing without mechanical components.
Designed for real-time performance on resource-constrained platforms, GstPTZR lets you manipulate the region of interest (ROI) in your video stream—in real time and at runtime—through standard GStreamer properties.
Key Features:
-
Digital PTZR Emulation
Simulates camera movement with smooth digital transformations:-
Horizontal and vertical panning
-
Zoom in/out
-
Rotation of the image around its center
-
-
Runtime Configuration
All PTZR properties (position, scale, angle) can be adjusted dynamically using GStreamer. -
GPU-Accelerated Performance
Powered by OpenGL, enabling smooth, real-time transitions even on embedded hardware. -
No Mechanical Components Required
A software solution for motorless PTZ cameras and scene tracking applications.
Example Use Case:
A security system running on Qualcomm RB5 uses GstPTZR to digitally track motion within a 4K video feed, zooming into the subject and rotating the frame based on AI detection. All transformations happen in real time without needing any physical camera repositioning—saving cost, power, and space.
