# 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
|
|
#
|
|
# Since this implements the `mypysink://` protocol you can also do:
|
|
#
|
|
# $ gst-launch-1.0 videotestsrc ! pymysink://
