RE: Windows DirectX 11 upgrade test thread - bossanova808 - 2015-12-21

So basically that's the end of decent Win7 support for Kodi?

@afedchin:
i had the settings in driver as describet in your link. then it seems its a driver (dxva) problem, because, as i describet, i get different results if i turn on/off dxva2 with one and the same driver-setting. (but i use win 8.1)

...because inaccurate video levels on a variety of hardware is a pretty fundamental problem, no?

You've got reports on nvidia, Intel and amd above...

You missed the fact that it's also on Win10

@crown08
Seems your drivers is corrupt or not properly supports dual graphics for DirectX11 applications.

Hi. I have a problem with Jarvis latest beta and limited range.
I have an htpc with windows 10 64bit.
My hardware is an E450 apu with HD 6230 gpu and Catalyst Driver 15.7.1.
The driver setting is set to rgb 4:4:4 (full range), kodi has enabled the 16-235 limited range option and the tv hdmi is set to limited.
With this settings I get black crushed. Using the AVS HD 709 black clipping pattern I should see black clipping bars but I see all black.
This is only with dxva render and dxva2 acceleration enabled. With pixel shader and dxva2 disabled I get the correct bars.
Here's the log:

@all
Please test this build KodiSetup-20151226 (+pdb)


RE: Windows DirectX 11 upgrade test thread - bossanova808 - 2015-12-27

@afedchin

Just tried that version (26th Dec).

AMD 6530D set to YCbCr 4:4:4 (and AMD reports 10 bit being sent to Denon X2100 Amp). Win 7 64 bit all current updated. AMD latest drivers 'Crimson'.

With hardware acceleration:
Kodi set to full range:
UI good,
Videos elevated blacks

Kodi set to limited range:
UI elevated blacks
Videos look like 'double' elevated blacks

Without hardware acceleration:
Results the same.

Debug log here: https://dl.dropboxusercontent.com/u/108804/XBMC/kodi-26thDec.log

Hope this helps!

20151226 version's black level: 0.022 fL, same as v15.2! I thought this wasn't possible with my setup. What's changed?
