Well, if you were writing your own application then yes. With
gst-launch-1.0, gst-launch should automatically link the pad to the next
element as requested. It's possible that it's not doing this in your
case here, because you never set any pads on the pad, and maybe it's
waiting for that. Check the GST_DEBUG log to see what's happening
between you activating the pad and pushing the buffer.
