I tested your scenario (minus the XE card) and the video played fine on my GTX 1060 - HW accel on are off both played fine.
Could you try on a different computer that is not using the XE card?

Hi, thank you for the reply and test out. From my side of testing, so far no issue on the graphic card we have except the XE graphic which come with intel latest gen 11 CPU. And my side just having 1 unit of pc equip with this CPU, so not sure is individual case or apply to all XE graphic card.

Suspect is the presentation layer in .net not been support by the graphic, because when use ffplay command to play no issue, and when the video playing in ffme, the graphic card usage also increase.

@mariodivece We just purchase a laptop with intel gen 11 gpu, and now can reproduce the issue, and my team found a solution to fix the issue from : cefsharp/CefSharp#3280

Added below code to force WPF render by software only
protected override void OnSourceInitialized(EventArgs e)
{
base.OnSourceInitialized(e);
HwndSource source = PresentationSource.FromVisual(this) as HwndSource;
if (source != null)
source.CompositionTarget.RenderMode = RenderMode.SoftwareOnly;
}

After we put in this code, then the video will playing as usual, and when the video playing the GPU 3D process usage will still rise, mean GPU still involve on the video processing part (maybe is from ffmpeg).

Just an update, so anyone face same issue can temporary fix by this solution first.
