# This simple example demonstrates how to create a set of Pipeline components,
# specifically:
# - A File Source
# - Primary GST Inference Engine (PGIE)
# - IOU Tracker
# - On-Screen Display
# - Window Sink
# - H265 RTSP Sink
# ...and how to add them to a new Pipeline and play.
#
# The example registers handler callback functions for:
# - key-release events
# - delete-window events
# - end-of-stream EOS events
# - Pipeline change-of-state events
