There is no gpu acceleration selection under settings > codec

4.5ghz i7

It's strange you don't have the D3D11 Video Acceleration option. Anyway, it should work with DXVA 2.0.

Make sure you have the Ouput option set to Automatic in the Video options tab. Then save, exit and restart VLC.

If it still doesn't work then open Tools -> Messages (set Verbosity to 2) before you start the playback, and then paste the full resulting log here or on Pastebin.com if it's too long.

I have exactly the same problem. It's all Software (with 100% cpu usage).
Using test files available here: http://jell.yfish.us/ (i used jellyfish-120-mbps-4k-uhd-hevc-10bit.mkv).
If i fire up the file in Media Player Classic it plays fine with H/W acceleration.

This is only for HEVC. H264 plays fine with H/W acceleration.

Reported this before (https://forum.videolan.org/viewtopic.ph ... 77#p446258) but it doesn't look like VLC team wants to fix it.

I see the op also have pascal graphic card. Maybe it's something like that since not everyone seem to have this problem (or they just accept software decoding)

When are we getting H/W accelerated HEVC in VLC?

It's strange you don't have the D3D11 Video Acceleration option. Anyway, it should work with DXVA 2.0.

2.2.4 doesn't show that, only 3.0.0 does (atleast for me).

HEVC HW decoding works in 3.0.

Not for everyone apparently. My logs are from latest 3.0

Asked my brother who also have a Pascal GTX1070 and same here: No HEVC H/W decoding:
He gets a slideshow like OP and me.

Here they even recommend people switching media player due to the lack of HEVC H/W decoding.

[yshdmt]

Is this going to be addressed? Is there any other form of testing/logging we can give the developers?

[Jean-Baptiste Kempf]

Your logs do not show anything related to hw acceleration...

[yshdmt]

Well my processor doesn't have HEVC hardware acceleration but my GPU does. Maybe VLC is trying to use DXVA on the processor? If my logs doesn't show anything about hw acceleration there must be something wrong in VLC. MPC with LAV Splitter plays it fine.

I have a GTX 1070 and I also cannot play these jellyfish test files.

[Lotesdelere]

Try VLC 3.0.0 nightly build.

And set it to use DXVA:
Tools -> Preferences -> Video
Output = Automatic

Tools -> Preferences -> Input/Codecs
Hardware accelerated decoding = DXVA 2.0

Then save, exit and restart VLC.

That's how we have it already. I'm on new Kaby Lake i7 7700K and GTX 1070 (both supporting HEVC H/W). You can't say with a straight face that HEVC hardware decoding is supported...

Just created an account because I wanted to post to confirm two things.

1 - Hardware HEVC decoding is not properly supported in version 2.2.4. Yes, the option is there, but no, it does not work.
2 - Hardware HEVC decoding appears to be properly supported in version 3.0.0. Enable DVXA 2 in the Codecs settings, and don't mess with the video acceleration (doing so caused artifacting for me, albeit smooth framerate).

In v3.0.0 I am able to play LG's demo material which is 4K 60fps 10-bit 4:2:0 BT2020 with HDR, without any stuttering or artifacting.
