How is Python plugin found

[Weipeng HE]

Hi all,

I am trying to run the gst-python example:
https://cgit.freedesktop.org/gstreamer/gst-python/tree/examples/plugins/python/sinkelement.py

I ran theses commands:
$ 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

But it says:
  WARNING: erroneous pipeline: no element "mysink"

I am wondering how is python plugins found in gstreamer. Is there any
documentation on this?

Thanks a lot!
