first of all, what is your dev env?

second of all, do you really have gstreamer-1.5 package config file?
try:

$ pkg-config --list-all | grep gstreamer-1.

third, print what pkg-config says with the following command:

$ pkg-config --cflags --libs gstreamer-1.5  (if you really have 1.5)

fourth, you are telling playbin to pick video sink.  I don't know which one
the playbin
is using.

does the following command work for you?

$ gst-launch-1.0 -v playbin uri=
https://www.freedesktop.org/software/gstreamer-sdk/data/media/sintel_trailer-480p.webm

if it works, it should print the video sink it's using.  (or at least it
should
print what it tries to use?)

best,
