Full Version: Windows DirectX 11 upgrade test thread
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
These test builds could possibly be unstable. Proceed with caution and always backup (wiki) your settings!

What is this:
  • These are test builds for anyone who would like to help with testing the DirectX11 upgrade.
  • No new features have been added to this version beside the current development done in Kodi nightly builds.
  • Make sure you have the latest driver for your video card installed and the most recent DirectX version. See Microsoft website for more details
  • The fix for the webserver crashing has not been integrated in these builds. So don't ask for them.
The main aim of this thread is to help identify issue related to the DirectX11 upgrade and not meant for general problems.

How to help:

Please include in your post:
  • Say if this was also an issue in previous builds or not.
  • A full debug log (wiki) posted on xbmclogs.com or pastebin.com
  • Possible crashlogs uploaded for download. Make sure you have the correct .pdb file placed in the install folder
  • The build date (in the download URL or in system info on Kodi). Specify which one you tried.
  • Details about your system (OS, hardware specs, videocard, driver etc)
  • Steps needed to reproduce the issue (play a movie, go to a file list, use an add-on, etc)
  • The more details, the better.
  • You may also post that everything is working as expected so we known current state of this development. In this case also provide full info.

Where to download:
Specific DirectX11 test builds are listed below. Other files in the "test-builds" directory are unrelated to this testing.
Builds will be updated on regular bases. Make sure you always try the most current one listed below before reporting problems.

  • 15.2-DX11 Installer (12 November)
  • please also download the .pdb file here, rename it to Kodi.pdb and place it alongside the Kodi.exe inside the installation folder (usually C:\Program Files (x86)\Kodi). Re-download the correct file each time you are install another test build. This helps us to identify possible crashes.

Stereoscopic 3D rendering:

Stereoscopic 3D rendering is only enabled on systems that have all the components that are stereoscopic 3D-capable. These components include 3D-capable display hardware, graphics hardware, peripherals, and software applications.

System requirements:

1. Windows 8 and later.
2. WDDM 1.2 video driver. (To check version of driver please run dxgiag on your PC and look at Driver Model at the Display section.)
3. DirectX 10 capable and higher video hardware.
4. 3D-capable display.

Also you need enable checkbox Stereo 3D settings for all supported displays in Screen Resolution control panel, as shown here:


Note for NVIDIA owners:

You have to install NVIDIA® 3DTV Play™ to be able to use hardware based stereoscopic 3D feature.


The changes are quite obvious. A full upgrade to the DirectX11 implementation and moving away from DirectX9 while keeping the backwards compatibility for past videocards and drivers to some extend.

Nice, just gave it a quick test.

Hardware: Windows 7 64bit, Intel® HD Graphics 2500 driver version
Debug Log: http://xbmclogs.com/show.php?id=425408
- The kodi logo looks a little blurry.
- Main sub-menu fonts disappearing
- Mouse control slow

@afedchin - updated link to a real debug log now (once I figured which guisetting to manually change)
Thanks. The log file did not throw any light on the problem. In next version I'll add more debug messages.

P.S. For debug log level I prefer use as.xml

very strange. I've even launched Kodi successfully on my virtual machine with Win8.1 x64. Looks like driver issue. Can you try to disable ATI card and try launch with Intel HD GPU?
Tested it for a moment or two, enough to get the library imported and try watching a few videos. I have the home submenus missing, item's text vanish from the list same for things like settings. Can be fixed by exiting and entering fullscreen mode again. Couldn't get any the videos I tested to work though they had sound, they were streaming off a SMB share, h.264 format (what my library consists of). Took two logs though I'm not sure if it was recording to log after switching so i relaunched it and tested the videos again.

Put up the videos, logs, screenshots, and what not on my google drive (Will take down the videos in a few days for legal reasons):

log 2: http://pastebin.com/DfJrR0Mw

Windows 8.1 64-bit
Intel Core i5-4670K
AMD R9 270X - Driver version: 14.501.1003-141120a-178000C (14.12)
there is no IntelHD graphics in my laptop - only the ATI. And with ATI disabled and using Microsoft fallback driver I still have the same issue. Dxdiag shows me that DX11 is installed (it's shipped with Win8.1 anyways IIRC)
uploaded a new build where he added more debug info
just tried uninstalling the ATI driver and use the windows driver - same issue. Will test with the new build.

edit: lol, this build is starting up just fine. I did both times a full setup to ensure it installs all requirements. Really strange.

I found a bug:
  • with DXVA2 enabled (not there without DXVA2) in video OSD settings when you enable picture post processing the "contrast" setting is not working correctly. Contrast is only changed when the slider reached the maximum value - but no change in any value between (brightness is working correctly)
Please, check with this new build in debug log why first try of creating device has failed. I think this message should be in the log.

I think what DXVA2 Contrast issue depends on GPU. I've checked twice in the sources it should works. I also have checked on my htpc and it works fine.
Thanks for your feedback.
1) Can you try same with integrated GPU?
2) Try to disable dxva decoding and with various render methods. This need to determine a possible reason of issue.
@afedchin - here is the debug log from my now starting version. Hope the info you are looking for is in there.

Regarding DXVA2 - It's just odd that the setting in general is working, just not any value between low and high.
