Need help to make a 4k video player

[CYCho]

I recently stumbled upon a 4k(3840 x 2160) mp4 video file and tried to play it with my zPlayer and I couldn't. I could hear the audio, but I coudn't see the video. I thought that I couldn't play it because my monitor was 2k(1920 x 1080). Then I found that VLC and and Media Player played it flawlessly. Windows Media Player Legacy also played it, but the video stuttered and lagged frequently, with very high memory usage. I tried WMPlayer.ocx and it was about the same as WMP Legacy. So I conjecture that, even if I had a 4k monitor, winmm.dll or WMPlayer.ocx would not be fit to playback a 4k video.

Microsoft says that MCI is a legacy feature and has been superseded by MediaPlayer. Maybe MediaPlayer class is the way to go. But how? It would be very much appreciated if someone could guide me to implement MediaPlayer with AutoIt. Thanks in advance.

My desktop configuration is as follows:
CPU: AMD Ryzen 5 3400G with Radeon Vega Graphics 3.70 GHz
RAM: 8.00GB
OS: Windows 11
Monitor: 1920 x 1080

Hey mate,

MediaPlayer is a winRT object (very early WinRT libraries here) , but it seems to work with a control used for UWP apps.  So I'd say its unlikely this will work but I'll have a crack.

We can certainly generate the MediaPlayer object, and the activation factory for the control:

#include "..\Include\WinRT.au3"
#include "..\Include\NameSpaces\Windows.Media.Playback.au3"
#include "..\Include\NameSpaces\Windows.UI.Xaml.Controls.au3"

_WinRT_Startup()

Local $pCtrlFactory = _WinRT_GetActivationFactory("Windows.UI.Xaml.Controls.MediaPlayerElement", "{77E525C3-EB17-4B8D-889D-1EA8ABDBD4EF}")
ConsoleWrite("Ctrl Factory: " & $pCtrlFactory & @CRLF  & @CRLF)

Local $pPlayer = _WinRT_ActivateInstance("Windows.Media.Playback.MediaPlayer")
_WinRT_DisplayInterfaces($pPlayer)


_WinRT_Shutdown()

The console output:

Ctrl Factory: 0x000002B7F0205958

I haven't created libraries for Windows.UI.Xaml.Controls.X objects as of yet - (the generator skips over anything that doesn't directly extend "system.object"). I'll have a play over the weekend and report back if it yields anything.
