GstPTZR

GStreamer Pan Tilt Zoom Rotation element

GstPTZR is a GStreamer plug-in that emulates a PTZR camera using digital image transformations.

GstPTZR is a GStreamer plug-in that emulates a PTZR camera using digital image transformations. PTZR stands for Pan, Tilt, Zoom and Rotate. They represent physical degrees of freedom in which the camera may rotate in order to capture different parts of the scene. GstPTZR uses OpenGL HW accelerated transformations to enable real-time performance on resource-constrained embedded systems.
