Video Video Player not using hardware acceleration

Hello,

I need to play 6 1080p Videos at a time.

When using Unity's Video Player component, I get around 25% cpu usage per video.
It's seems Unity using a software decoder.

I know that Unity uses the Windows Media Foundation API on Windows (my target). This API enables Unity to have hardware acceleration for h264 videos.But somehow it doesn't use it?

I already re-encoded the video to make sure it fits the specs.

For comparison: If I use the ffmpeg player ffplay.exe to play the video it works even with 8 simultaneous 1080p playbacks at the same time.

How do I get hardware accelerated video in Unity? Does someone has a ffmpeg converter config or a video that's definitely hardware accelerated on windows?

Here is the specs of the video file (ffprobe)

Spoiler: ffprobe output

What is the status of this in the newer releases of Unity?
