Actually gst_element_get_request_pad() doesn't work, I get:
GStreamer-CRITICAL **: Padname sink_0 is not unique in element mixer, not
I'd forgotten about this while I was stumbling around trying to figure out
how to do it before I came up with using gst_element_get_pad().
It seems the "depreciated and to be removed" gst_element_get_pad() function
does something that can be most useful and code simplifying.
Namely returning a reference to a request pad that was automatically linked
gst_element_link_many(source1, colorspace1, scale1, I420filter1, vrate1,
tover1, queue1, mixer, NULL);
In light of this, I think removing it from a future version would be a
mistake, unless a clearly documented better way is introduced.
