HEVC/X265 - 100% cpu load (2 Viewers)

[BigAlb]

On My laptop:

Using MP 1.11
tears = Quite stable at ~20% CPU. No frames dropped.
tractor = ~30% CPU. No frames dropped.
bunny = 100% CPU. Frames dropped.

Which codecs, and what are the specs of your laptop?

• LAV 0.64.0 (none, DXVA, QS and CUVID result the same cpu usage so it seems no gpu acceleration)
  
• i5 4200H
• inbuilt Intel HD4600 + Nvidia 840M
• Windows 8.1

Thank you for the testing! Could you try the 3 sample files directly within GraphStudio and/or MPC-HC (latest version uses integrated LAV filters 0.63)?
Considering your setup, IMHO you should be able to have a decent playback also for the "bunny" video.

Interesting results in different means:
1) Working on Texture as callback doesn't lead to reduced CPU load (but improves GPU performance though, due to one copy step less)
2) Decoding performance of Tears and Traktor is nearly same in VLC and MP2, while Bunny is quite higher
3) Decoding inside GraphStudio using LAV is on same level here

Windows 8.1
CPU: i5 2500K
Graphics: AMD R7 240

Bunny   VLC: 35-45%     MP2 (copy): 45-76%     MP2 (Texture): 45-75%   Graphstudio: 75%
Tears   VLC: 12-14%     MP2 (copy): 12-14%     MP2 (Texture): 12-14%
Traktor VLC:  8-11%     MP2 (copy): 15-20%     MP2 (Texture): 19-21%

• Intel Q6600
  
• AMD HD5470
  
• LAV 0.64 with HEVC & UHD selected for dxva

MP CPU ( system CPU ) :
Tears : 28% ( 50% )
Tractor : 43% ( 65%)
Bunny : 80% ( but system 100% ) Frammes dropped

Ps : bunny is 4K stream and other are FullHD

I invite you to test other codecs too.

I tried Strongene Lentoid HEVC decoder. After registering it (double checked with GraphStudio that it was the preferred codec), the point is the same: for some reason, the cpu load with Mediaportal is much higher than that of MPC-HC with the same codec, as it was for LAV filters[DOUBLEPOST=1428831510][/DOUBLEPOST]

Hi azzuro, could you try to play the videos in GraphStudio or MPCHC?

 

[azzuro]

i can try, but i'm pretty sure my GPU is not abble to decode this file corectly.

Please Guy use Dxva checked

My Gpu is only abble to decode H264 in FullHD.

Edit ; for me it's normal if MP is more GPU usage, because we use it for rendering GUI.
but maybe i'm wrong

i have try MPCHC,
sure the stream is better than MP. but i have 100% cpu usage too.

Here is my GPU, cannot find anything *265* or HEVC related...

Anyway IMHO a little bit of overhead by Mediaportal is acceptable/reasonable, but on my setup:
1) I do not experience any overhead with other content (e.g. h264) - or maybe it's so small that I cannot perceive it;
2) with HEVC the overhead is really huge (like twice the cpu load or more) and this leads to frame dropping in all the real world files that I have (besides sample ones).

Besides bunny (indeed very cpu intensive), I have got:
- Tears: 20% vs 50%
- Traktor: 30% vs 80%

Can you confirm this kind of cpu load on your setup using LAV filters?

 

[azzuro]

I can only in the afternoon.
Your gpu must be recent. Like moprheus gpu.

 

[Sebastiii]

MP use more GPU memory because of GUI related
So in MP it will consume more GPU (maybe related to memory) but for sure i have the same with normal H264 HD channel on my old laptop, when i display some GUI, it stutter like hell even if i didn't display some GUI, it stutter but less and compared to a better GPU it's stable and like to decode H265/HEVC we need more power or recent GPU then i think it's normal.

These are my GPU capabilities

AFAIK there are no hardware supported HEVC DXVA2 decoders yet, except some high level NVidia cards. This means decoding depends on pure CPU only.
And as my numbers from above show, for my system the GUI overhead is not so much (<10% for 1080p, but ~30% for UHD) for MP2.
