# Small test application to show how to write a sink element
# in 20 lines in python and place into the gstreamer registry
# so it can be autoplugged or used from parse_launch.
#
# You can run the example from the source doing from gst-python/:
#
#  $ export GST_PLUGIN_PATH=$GST_PLUGIN_PATH:$PWD/plugin:$PWD/examples/plugins
#  $ GST_DEBUG=python:4 gst-launch-1.0 fakesrc num-buffers=10 ! mysink
