NUC6i7KYK freezes during Video playback
I bought a NUC6i7KYK yesterday and it completely freezes up in the first 30 minutes, but only when I play video.
It doesn't freeze when I play a game or stress the CPU.
It doesnt freeze or give errors when I run Memtest (EFI version) overnight.
However, the strange thing is that it consistently freezes when I play a video using a .NET app that uses the WPF MediaKit Library to play DirectShow within .NET.
I think it is using LAVFilters to decode because I also have Media Portal installed, which installs LAVFilters. I haven't installed any other codecs.
WPF MediaKit: GitHub - Sascha-L/WPF-MediaKit (the library has a test app you can use to play video)
LAVFilters: LAV Filters 0.68.1.31 Free Download
Media Portal (I use MP1 v1.11) Download MediaPortal for free! - MEDIAPORTAL
If I play video using MediaPlayerClassic, the system doesn't freeze as much (only once so far). I think MPC-HC uses its own video codecs to decode.
When it froze using MediaPlayerClassic, the video slowed down to a craw and then stopped and the app completely froze. I then tried to open Task Manager by right-clicking the taskbar, but when I clicked on "Task Manager", the menu slowly went away leaving the Task Manager button hovering in mid air. I then tried to open the Start Menu, it appeared once, then next time it didnt appear at all. Windows itself was now completely frozen up.
This sounds like the same problem the person playing DOTA2 saw happen.
I tried increasing the RAM timing in the BIOS and also disabled that RAM Latency enhancement option, and also disabled PCIe ASPM power management, disabled Thunderbolt and a few other devices, but that just made things worse. It now freezes within two minutes of playing a video.
I tried updating the BIOS (037) and graphics driver to the latest (4481), made no difference.
I tried updating LAVFilters, no luck.
I have the exact same software and codecs running on two other Intel PC's (Haswell Desktop, Ivy Bridge notebook), no problem at all.
SSD: Toshiba M.2 512GB
RAM: 1x 8GB Kingston ValueRAM KVR21S15S8/8 (in bottom slot)
OS: Win10 Home 64bit with TH2 (Fresh install)
Monitor: HDMI LG superwide curved LCD (High res but not 4K)
Video format played: DTV recordings in MPEG2 TS format
....so is it a GPU Iris video acceleration problem? Or RAM compatibility problem? GPU Driver problem? BIOS glitch?
I tried using FFDShow, still freezes.
I tried using Intel QSV rendering, still freezes.
I tried using DXVA acceleration, still freezes.
To me it seems to be a problem with the Iris Pro GPU or driver. I'm guessing it's a memory leak in the driver or cache problem in the GPU.
