Hello,
I updated to Win11.
I installed MPC-BE as above.
Now I see that the HW decode works properly and no CPU usage.
I installed FRAPS software to monitor FPS, see results below (yellow numbers):
Clip: "ext h.265 4k 50 4_2_2 10b 100Mbit L5.1-high"
Minimized window: 50 FPS
As I increase window size FPS decrease, 35 FPS @Max size
In order to get nominal FPS it is necessary to play video not showing controls, statistics, search bar...
In this situation CPU & GPU activity is as below: "perfect"
Also clip "ext h.265 4k 50 4_2_2 10b 350Mbit L6.1-high" plays smootly at 50 FPS.
Just to check NUC+MPC-BE capabilities, I tested another clip "ext h.265 4k 50 4_2_2 10b 700Mbit L6.2-high". Maximum FPS that can be achieved is 30, not too bad.
So, my fear that this NUC could not play as I expected has gone 🙂
As you said: "The video player seems to have more influence on the use of hardware acceleration than one might think."
Many thanks MUC for your valuable support. 😊
If you're coming to Madrid (Spain) someday, place a message on this post (I will receive a notification) and will drink some beers!.
Good luck.

Hello MUC,
Thanks for your help.
If I understand properly the document you linked, the 12th generation should be capable to HW decode it, so, do you know why my NUC is not capable to do it?. Is there something I am missing?. Should I upgrade in some way the NUC HW?, Or is it related to W10 version or Drivers?
Best regards.
Your device is a NUC12WSHi5 ?
The latest driver would then be this:

As I understand it, no other special requirements should be met. However, I am not familiar with self-made recordings. According to the operating instructions, the X-H2S can do:
Have you tried whether you have better luck playing files recorded with the other file types and compression modes?
YCbCr 4:2:2 is not common in media distribution and is therefore a “special case” for me. Please note that the physical layer (PHY) of Intel graphics products does not output an YCbCr 4:2:2 signal. Either RGB or YCbCr 4:2:0 is sent, even if a video file is decoded from YCbCr 4:2:2 using hardware acceleration.
One possibility would therefore be to create the recordings from the outset with YCbCr 4:2:0. This also saves disk space.
Hello MUC,
Yes, my CPU is NUC12WSHi5. Already installed last version driver:
No problem with Disk space, I wanted to record 4:2:2 to have better color resolution than 4:2:0. Also 10 bit, instead 8bit, for better color gradients.
I recorded some clips 4:2:0 and they were played as expected (NUC using HW decoding), but when trying with 4:2:2, no HW decode.
Let me say that my records are not intended to media distribution, they are just for familiar usage (family memories).
Regarding your comment "Please note that the physical layer (PHY) of Intel graphics products does not output an YCbCr 4:2:2 signal. Either RGB or YCbCr 4:2:0 is sent, even if a video file is decoded from YCbCr 4:2:2 using hardware acceleration." I would like to better undestand what is behind that. Could you please let me know where can I find the source information?. Does It comes from Intel?
Do you know if it is related to HDMI output?. I mean, If I use Display Port (via thunderbolt USB C connector) may be the problem could be solved? (DP better capabilities than HDMI)
I read that "12th Generation Intel Core Processors Datasheet Volume 1 of 2" (page 140) shows:
But I do not know if MPO is already enabled on my computer. Also I do not know if i51240P SKU can affect to the 4:2:2 HW decode.
So, considering info on hand, I think that i51240P should work for 4:2:2 HW decode, and I would like to understand why I am not able to find the solution.
Do you know if there is some document detailing specifically i51240P HW decode capabilities?
Any help will be highly appreciated.
The video player seems to have more influence on the use of hardware acceleration than one might think. I cannot achieve hardware acceleration with VLC media player. But with Media Player Classic Black Edition (MPC-BE) in conjunction with the MPC Video Renderer:
I also ran the same test with another PC with an Nvidia GeForce RTX 3050. This does not enable hardware acceleration here.
So please install MPC-BE.
- Download: https://www.videohelp.com/software/MPC-BE
- Also select the MPC Video Renderer for installation:
- Run MPC-BE:
Done. Please check now whether playback is satisfactory using MPC-BE.
