Activating pads when adding dynamically before entering PAUSED state

[Tony Houghton]

Related to my most recent post, I've got a simpler question about adding
pads dynamically. Apparently, when adding a pad to an element, you should
call gst_pad_set_active(pad, TRUE); and examples show this being called
before adding the pad. But according to the API
<https://gstreamer.freedesktop.org/documentation/gstreamer/gstpad.html?gi-language=c#gst_pad_set_active>
this
calls its activate virtual function. I would have thought a pad should only
be activated when it's at least entering PAUSED state. And shouldn't you at
least wait until the pipeline's push/pull mode has been negotiated? What if
I want to add a pad before either of those conditions?
