That's correct. Signal emission never takes ownership of the parameters
but instead increases the reference count internally. You need to unref
your buffer after signal emission in one way or another when it's no
longer needed by your code.

It is generally a better idea to use gst_app_src_push_buffer() for that
reason, as that would allow the buffer to have a reference count of 1
and thus be writable for elements in your pipeline without first
requiring a copy.
