Does anybody have some update here?

Hi
I have noticed that ticket https://trac.videolan.org/vlc/ticket/24922#ticket is closed with below comment
“10bit 60fps AV1 without SIMD..
wait for 10 bit SIMD”

Is this feature going to be supported and if yes when?
Seems that windows10 app “Movie & TV” already supports this

Hi forum
I see following note in ticket
“10bit 60fps AV1 without SIMD..
wait for 10 bit SIMD”
When is support of this expected?

Yes, exact same video shared at https://e.pcloud.link/publink/show?code ... YH0kzwkc9y is playing fine on my DS10U5 with with "movie & TV" app.
But same video with VLC goes to appr. 100% CPU since GPU apparently is not used.

No, since movie and TV app can do the job, issue is with VLC - exactly as mentioned in ticket.

Yes, I have observed exactly the same on same PC which has issue playing with VLC.

Hi
Let's focus on issue with AV1 coded mp4 as described in ticket.
As mentioned this same video is playing fine with Movie & TV app in windows10 as soon as you install AV1 extension

Thanks a lot thweiss.
Pls. let me know if you need any more info from my side.
Br Peter

fine, that’s almost the same I am observing. And almost same pattern with 5k player.
But as mentioned same video is playing fine with movies & TV app in this PC.
Hence I don’t see this as an issue with windows10 or HW.
So how to proceed with this issue?

still wonder why "movies & TV" app has no issue....
anyway let's continue debugging as per your advice.
also if needed you may dial in to this PC via e.g. teamviewer

fine, will do.
still wonder why "movies & TV" app has no issue....

Hi As mentioned my setup is slightly different: DS10U5 including intel UHD Graphics 620 with 24 P2415Q Dell monitor attached via DP cable. Ad 1: Have tried, no change Ad 2: No, I am on 1.02. But as movie TV app is having no issue, I don’t see the need to upgrade BIOS at this point. Let’s rather syst...

Hi Thanks for response. Intel UHD Graphic 620 already checked. Test file used here is: https://youtu.be/LXb3EKWsInQ downloaded via 4Kvideodownloader in 4k resolution. I have same issue with other 4K videos downloaded same way. Meanwhile I verified that the "movies and TV" app in windows10 ...

1. link is https://pastebin.com/hbQs5Z6b
2. as said I think main issue that your player does not recognize the GPU Intel 620
3. hw acceleration enabled and video is playing correctly, however it goes to 100% CPU while playing
br Peter

Also note that player MUST know that GPU is Intel 620.
Otherwise all load is on CPU, and not on GPU.

Hi

Pls. find attached info as requested: 1. 4K video used here is from youtube id LXb3EKWsInQ downloaded via 4Kvideodownloader in 4k resolution. 2.

OK, will do

Hi forum I just wonder if it is correct that vlc player uses appr. 100% CPU on my new shuttle DS10U5 with 16 GB ram when playing 4k or 8k videos downloaded from youtube. Memory utilization ~ 46%, which is OK. It does play correctly though, but obviously I can’t do much other things when video is pla...
