Still happens with playbin3 too.

Just run:

GST_DEBUG=*videodecoder*:5  gst-launch-1.0 playbin
uri=http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4

and see "do query ALLOCATION" appears twice in the logs.

Both from the same line of code
https://cgit.freedesktop.org/gstreamer/gst-plugins-base/tree/gst-libs/gst/video/gstvideodecoder.c#n3706

I did an initial analysis in the bug description. If you are interested in
optimizing it please feel free to go ahead otherwise you can close this bug,
thx!
