Summary0000582: Matroska/Upstream cropping doesn't work in DXVA2 Native mode
DescriptionHello,

the Matroska/Upstream cropping doesn't work correctly in DXVA2 Native mode. The size of the rectangle and the aspect ratio is right, but the choosen pixels aren't: It doesn't crop at the top, but only at the bottom (and it crops more than it should there -- so much that the size is right). Here is the pin info MPC-BE reports:

Steps To ReproducePlay the file "Matroska.Container.Cropping.mkv" in MPC-BE with its internal filters with DXVA2 native enabled. You'll see a black bar at the top and you'll also see that the white rectangle isn't centered, but below the middle of the video (it should be a white square in the middle of the video and you shouldn't see black bars at all).
Additional InformationI have already reported it on doom9 here: http://forum.doom9.org/showthread.php?p=1854410#post1854410 [^]
The EVR and EVR-CP renderers are able to correctly crop in DXVA2 mode (if the cropping doesn't respect the subsampling, they are off by one, but I'd be satisfied with this).
It works correctly when not in DXVA2 native mode.
LAV Filters ignores the Matroska container cropping parameters and can therefore not be used to reproduce this issue. But MPC-BE's internal filters work.
