Write your own source element, deriving from GstPushSrc for example.

How do you determine that fakesink does not receive any buffers? Note
that silent=false won't print anything out, that only happens with
gst-launch-1.0 -v because it hooks up to the deep-notify signal of the
pipeline. If you set fakesink dump=true it should print stuff though.

Also note that you don't have to use the need-data signal if you don't
want to, you can just push data to the appsrc whenever you have some
(depends a bit on your data source I guess).
