# This example demonstrates interpipe dynamic switching. Four DSL Players
# are created, each with a File Source and Interpipe Sink. A single
# inference Pipeline with an Interpipe Source is created as the single listener
#
# The Interpipe Source's "listen_to" setting is updated based on keyboard input.
# The xwindow_key_event_handler (see below) is added to the Pipeline's Window Sink.
# The handler, on key release, sets the "listen_to" setting to the Interpipe Sink
# name that corresponds to the key value - 1 through 4.
