The demo video player in full pass-through mode. We're getting there!

A terminal running intel_gpu_top on top of a fullscreen video player playing Big Buck Bunny. intel_gpu_top reports that the video player does not use the 3d/render engine at all, only using the video engine for decoding.

In case you wondered how things look on AMD: this is BBB 4K@60FPS and the corresponding radeontop report.

BBB in 4K@60FPS, playing on a 2560x1440 screen in zero-copy mode.
A terminal running radeontop, showing no 3D engine usage.

@rmader are you sure hardware video decoding is working on the AMD? Everything looks suspiciously at 0%

@frox That's the point ;) If it wasn't using full zero-copy you'd not get 0% for the whole 3d engine.

@rmader ah right, didn't know that about radeontop.
These hardware acceleration developments are really impressive.
