Can't play video on windows xp

Lazy loaded dlls would have a hourglass mark with the icon, like MPR.DLL / IESHIMS.DLL in your picture.
Your MF.DLL and MFPLAT.DLL seems to be direct linked, also your D3D9.dll is red so it may miss functions.
I would guess it is due to the DX lib when you compile Qt, as I said.
I don't have any 5.6.3 dlls on my machine but I have a deployed application of 5.5.1. Checking by dependency walker, the official prebuilt msvc2013 dsengine.dll of 5.5.1 doesn't depend on mf.dll and mfplat.dll directly.Maybe your compiling links newer DX libs that not supporting xp. I would guess it is due to the DX lib when you compile Qt, as I said.
You mean i should install Directx9 on my windows7, remove all other DirectX versions and compile qt5.6.3 again?

You may be able to compile only the dsengine plugin.
But I don't know how to make sure you link the xp supported DX lib, since I don't target xp for at least 5 years... -

Hi, one other thing I saw in the dependency walker's output, it wants the Qt files from another Qt directory on your XP machine:
c:\tools\neovim\neovim\binMake sure that this other version exists and is also Qt 5.6.3 Release for MSVC 2013.

Hello. I have some questions:- Why application loads these
.dllsfrom that weird directory instead of current directory of my application? (I usedwindeployqt) - Lets say, i fixed it. Do it fix main issue?(Showing video)
- Why application loads these

@LinArcX
Hi
1: Ask Windows :) It is its run time loader that controls this.
2: It could fix it. However, the normal effect of mixing Qt version is crashes so
dont get to much hope up.@mrjj I mean why it didn't look in current directory first, if it looked why doesn't load it? Since those dlls exists beside main exe file.
I noticed that on windows xp that doesn't have this directory(
c:\tools\neovim\neovim\bin\), DependencyWalker complains that it can't find dlls:

Well back in the Xp days they didn't load better i guess.
In the newer version of windows, you can add a manifest file to tweaking it and at some point they also allowed
side by side loading of Dlls with same name etc.
https://docs.microsoft.com/en-us/windows/win32/dlls/dynamic-link-library-search-orderwell (c:\tools\neovim\neovim\bin) seems just to be
https://github.com/neovim/neovim
but it does uses Qt for GUI .Hmm so the DSENGINE cannot find its support DLLS ?
those missing files are in your app folder ?Is there a reason you cant use a virtual machine with Xp (or real pc ) to install Qt5.6
and what ever compiler you wish and simply compile and xp version for xp.
And compile a win 7+ on win 7 ?
Im not 100% sure you can have a one .exe that works on both as the backend changed alot. -

It works on xp?

Exactly.
Is there a reason you cant use a virtual machine with Xp (or real pc ) to install Qt5.6 and what ever compiler you wish and simply compile and xp version for xp.
I tried to compile qt 5.5.0 on windos xp.(It's a virtualbox machine). It complains about some functions that only exists on x64 architecture.
Im not 100% sure you can have a one .exe that works on both as the backend changed alot.
So, you mean i should compile whole application in each os separately?

I think so but not sure if it can help you load the right dlls.

But Qt5.6 still supports Xp so why compile your self? You add something ? -

Well that is how a few people I know still do - to have xp version. Its only SP3 Xp's that works but I guess
all remaining xp's are patched.
It might be less work than to make sure it links to older directX in newer windows. (if thats even possible)
