This is what I would also recommend. The GST shipped with Raspbian is
patched to add conversion to RGB color space and scaling. This is how
they manage to have decent performance to on-accelerated layers, but
this is still a copy.

A rendering path that is quite efficient is the EGL path. This is what
you will gain by using glimagesink. This is going through the DispManX
layer (specific to this broadcom VPU). You might need to patch gst
-plugins-bad a bit so the window placement becomes configurable.
