That is a Media Foundation decoder and can only be used by applications that use MF.
The players you mentioned do not use MF, they use DirectShow filters.

it's a pity to hear that...
i cant understand why MS separated the MF environment from outsiders which makes their long term effort on DirectShow environment useless.

opensource decoder are usually faster anyway.

older version have been tested and they are not impressive. only when HEVC was fresh the microsoft decoder was faster in 32 bit a lot has changed since then but not for the microsoft decoder.

Anyone can use Media Foundation, its not "separated from outsiders". Its just that rarely anyone does, except MS itself in the Movies & TV app.

You can test it using DXVA Checker both in SW and HW mode, but it's been a while last time I remember checking it for myself.
When I decide to upgrade to Windows May 2020 version, I'll probably give it a try again.
But the only real player that you could actually use it is Movies & TV, so it has very limited use as all previous guys have already said.

@NikosD do you prefer pro decoders or open source decoders?

Thanks for bringing back the things about older versions.
I heard sayings that new version of HEVC video extension has a surprisingly high performance. I tried it on an old small rig and seems HEVC VE on HD530 runs much faster than Lentoid either on HD530 or GTX960m...
Still not sure if the outperformance only shows up on older hardwares...

I strongly wish I could give better test than a brief try but not enough rigs around for the time being... but will definitely look forward to your analyze
On my old rig, the HEVC VE occasionally hangs on the middle of a UHD 120fps clip in Movie&TV; I tried the similar clips on the old school WMP who claims it also uses the HEVC VE although being replaced by Movie&TV, the hanging never happened then... but still may need more tests to confirm...

the HD 530 can do HEVC in hardware.
so you are not really comparing it because the GPU is used. the decoder you should compare it to is ffmpeg and both without hardware decoding.

What is your Windows OS version ?
I'm not sure that WMP uses MFT filters at all or in higher priority than DS filters.
Although there was a time IIRC that could use both, first priority MFT decoders and if failed or non-existent it was falling back to DS filters.
Probably LAV filters or other DS decoders installed on your old rig are doing the job of HEVC decoding.

I'm eager to read about AV1 decoding performance of Xe, but unfortunately I can't see how could I test it.

I hope someone will buy a laptop or desktop processor with Xe inside and AMD/ nVidia jump to AV1 wagon sooner rather than later.

I had high hopes that maybe after years and years the new AMD RDNA2 GPU architecture of Navi 21 could beat Ampere or at least be very close to Ampere GPU of nVidia.

The last rumors regarding Navi 31, the next next generation RDNA3 are not good regarding RDNA2, it could be a sign that RDNA2 didn't make it.

Ampere for gaming will be released on early September and Navi 21 for gaming probably around November.

So, let's wait just a few months more and hope that both of them have added AV1 fixed-function decoder like Intel did with Tigerlake launching September 2nd but only as internal iGPU for start.

Funny: For once it isn't madVR that is affected by driver bugs, but mpv: I'm getting delayed frames with D3D11VA Polaris and recent drivers + 144Hz display. AMD Windows driver team did it again.
It (of course) works fine on Linux Xorg with VAAPI...

Rumors are at highest level, but nVidia offered yesterday an official date of Ampere:

August 31th.

Latest leaks are talking about 20GB and even 24GB VRAM for Ampere.
AMD is at 16GB for RDNA2.

AMD is going to beat 3080 but above this, it's very difficult.

There is a marketing game or war right now and it's not easy to find out what is really going on with so many info.

But the day is coming.

So Tiger Lake will have 8K60 decode but no HDMI 2.1.
I know it's a laptop chip so it's not that useful, but it would be on something like a NUC. It's a pity they're still lagging one generation behind what the best TVs are capable of when it comes to HDMI.

Renoir doesn't support HDMI 2.1 either though and I don't think it's a big deal for Tigerlake-U. 4k devices are super premium and rare, out of 500 Icelake devices there are like 10 devices with 4K displays. Adding HDMI 2.1 would have increased the die size quite a lot for a small nice, this is a bad return on investment.

He probably said that combined with the ability to decode VP9/HEVC streams up to 8K60 fps.

Renoir doesn't have that fast decoder.

Anyway, Tigerlake is well described, the only thing left is to measure decoding performance.
I think is going to be faster than Turing in both VP9/ HEVC and with additional support of AV1 HW decoding.

I can't wait to see nVidia's GeForce Ampere card supporting PCIe v4.0 and HDMI 2.1 along with a new decoder capable of AV1 8K HW decoding and faster 8K HEVC/VP9 decoding.

Hope exactly the same for RDNA2.

Of course the same goes for HW encoding and gaming performance.

Around the end of this year, all options for CPUs (Rocket Lake vs Zen 3) and GPUs (Ampere vs RDNA2) will be on the table for Cyberpunk 2077 and MS Flight Sim 2020

For the first time in recent history that I remember, nVidia seems to be afraid of AMD and that's good because also for the first time, prices look reasonable.

The presentation from leather-jacket man was mainly marketing and less technical and too short.

It seems that Big Navi and next-gen consoles pushed hard nVidia.

By eliminating Titan series and making it a Geforce 3090 card with 1500$ price it seems that this card will be unreachable by AMD, but 3080 will have competition.

So, PCIe v4.0 is here like HDMI 2.1 and AV1 decoding.

Fingers crossed for Big Navi.

"presentation from leather-jacket" Yes, you know, just like one of us
Yes, I agree, although prices are still (very?) high for me. I'll be curious about AV1 decoding when time comes...
