-- Maintaing decoded surface resoluton and actual display resoultion separately -- Before pushing every frames downstream, check for the requirement of pool negoation and output_state negotiation: This is needed to avoid multiple issuses with cropping, multi-resoluton video handling, more complex multi resolution decode scenarios for vp9decode, possible wrong behaviour from upstream element to report uncropped values etc. Due to these reasons, We can't just reliably use the resolution change notification from libgstvaapi for pool renegotiation too. This is slight overhead, but safe enough. Optimization could be possible though. https://bugzilla.gnome.org/show_bug.cgi?id=753914
