Intel HD Graphics 630 Playback H265 DXVA2 Bug

Mike_F_1 — Sun, 26 Feb 2017 08:44:47 GMT

Playback from H265 Sources with activated DXVA2 has an Alaising to the picture:

When I deactivate the DXVA2, then is the picture normal. Driver:21.20.16.4590, Windows 10 x64, Player Kodi V17.

[edit]

Seems to be a problem with Intel Graphics Settings / Video / Image Enhancement / Contrast Enhancement.

Disable this setting remove the effect. The Effect only appear on H.265 (HEVC) coded videos

Thanks Mike,

The issue has been reported and will be investigated. Sory for taking so long I have been on an extended business trip.

Hi Mike,

We have been unable to reproduce your issue. Is there a specific file you can recommend or send me that will show the problem?

Sorry from bringing this

Sorry from bringing this thread from the dead but HD 530 has this same exact issue, it only happens when you play x265 encoded video.

Driver version I have is 22.20.16.4771 on Windows 10 64bit.

Happens for me too on two

Happens for me too on two different laptops with Kaby Lake processors. i3-7100u and i5-7200u. My player is MPC-HC 1.7.13 with hardware acceleration for HEVC enabled and Intel's contrast enhancement enabled. Driver version 21.20.16.4534 which is the latest my OEM has out.

Here's a sample MKV file that exhibits this behavior https://mega.nz/#!f2QxiQpb!1pI3Q_BIW4usYuw6ct1IhBeEnU7qrQAHKwEG9RfdD58
