# 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
