SVP 4 Mac (Page 3 of 5)

> no hwdec actually makes it faster

well, it makes sense if you only compare them playing Hi10p videos cause Hi10p decoder is software-only

> My Mac almost always goes over 90%

this's not good, you won't get stutter-free playback with 90% system load

> if SVP has gpu acceleration but I've disabled it on mpv config file, hwdec=no, is it still using it?

this's different, hwdec is about video decoder and SVP's acceleration is just a SVP's thing

> For this particular file I just can't watch it without stutterting. Not sure why:https://www.koi-sama.net/files/hi10/

FullHD hi10p source is a difficult task for a 2 Ghz "i3" cpu, you'd better start with 720p videos...

video HW Acc is different from OpenCL HW Acc which uses SVP.
Have you tried to manually tinker with SVP options clicking on Automatic settings (which is a button).

i just bought the Mac version for my 2013 MacBook Pro Retina 2.4Ghz 4GB RAM. To tell you my experience lets start with the Free Windows version. I have a reasonably good gaming PC with Intel Pentium G3258 + 8GB RAM +  Asus R9 290. The free version works great on that PC with everything scrolled to the max of slider (High Quality). And I checked on the use GPU acceleration.

Actually I haven't tried it without GPU acceleration. Will try it out next week. Probably will destroy that G3258. But yeah. I'm so pleased with the performance on my PC.

Now onto my Mac.
It's hard for me to tell you how it performed overall because different video file produces different result.

But all my videos are 1080p.
But they have different bitrates and I think that affects interpolation performance too.
The bitrate ranges from 16.5Mbps - 35.26Mbps.

Actually I'm not really good at these hardware/software decoding thing.

To make it simple, it stutters quite a bit (like 5% of the video). What I did to minimize the stutter is:

• use optimized for Animation. (for some reason Film didn't work out for me most of the time)

• set slider to about 3/4

• LOW artifacts

• No GPU acceleration. Bcuz I believe that the Iris GPU is weak.
  

And since I do not have any expertise in MPV config, I just follow everything you have returned in the Installation webpage:

input-ipc-server=/tmp/mpvsocket
hwdec-codecs=all
hwdec=auto-copy
opengl-early-flush=no

The only thing that really make significant improvement is that opengl-early-flush=no

if i set it to yes / auto or if don't set it at all, stuttering will become more obvious.

so, admin, do you have any suggestion for me to improve the performance on my Mac?

> Bcuz I believe that the Iris GPU is weak.

it's not weak if we're talking about video decoding + SVP + default "opengl" profile in mpv
haven't tried it with "opengl-hq" profile though

it's weird right? at first i really thought like "ok this is a mac. with that special Iris iGPU. lets use that GPU acceleration"

then boom. stutters all the way..

actually i learned something from my friend's PC that is using 2nd gen Core i7-2600 + radeon 4000 series (i cant remember exact model).
when i select use GPU acceleration, video stutters like hell. (maybe bcuz of that old radeon card)
when i deselect it, video was buttery smooth. (thanks to that powerful core i7 ?)

i think this is the situation where you don't have to use GPU acceleration when you already have a good CPU.

so i applied that to my own Mac. and it really works. Less stuttering after disabling Iris GPU acceleration.

still weird though. Iris is part of that CPU since it's integrated. but why it failed to decode properly? any clue on that?

and regarding that "optimal retina scaling", how to do that?

> you don't have to use GPU acceleration when you already have a good CPU

I must mention that GPU rendering is different from CPU rendering in SVP, it gives more "smooth" picture.

I personally don't see any issues playing 1080p on 2K screen from Mac Mini with Iris graphics and all acceleration turned on, probably because Mini has much better cooling system than any Mac laptop.

As for now I'm quite satisfied with the result even if it's not as perfect as my PC with high end graphic.

now i've enabled GPU acceleration on my Mac which i guess the right thing to do.
I love to watch everything in 60fps though.

Since both my Mac and PC are using dual-core CPU,
I don't like to waste my time on converting video from 24/30fps to 60fps using
those Avisynth interpolation technique described in http://www.spirton.com/convert-videos-to-60fps/

So if there are any recommendations/suggestions please let me know ya. Thanks.

Yes I have tried, but apparently nothing happens. :S

I've tried with hwdec=auto-copy" and it seems there's a lower CPU usage while monitoring it with the svp hardware monitor (I would say the average is about 65-70% while without it is about 75-85%.

I've also changed it to animation, low artifacts and opengl-early-flush=no as another user recommended.

> How can you install vapoursynth without homebrew?

https://gist.github.com/ChrisK2/10606922

I'm stuck installing vapoursynth.

When I type "./bootstrap.py" into terminal it says: -bash: ./bootstrap.py: No such file or directory

What do I have to do after downloading "brew install python3"?

Thanks!

EDIT. I've tried following this:http://www.vapoursynth.com/doc/installation.html but requires home-brew which is El Cap minimum...

Do you think my 2010 MacBook Air with the NVIDIA 320M and Intel Core 2 Duo 1.86 GHz SL9600 will be able to handle SVP? If it can't I might as well not try updating because I have many files stored here and it will be pretty annoying to deal with it,

720p will do fine (this is what I'm watching most things anyway since the restriction of YouTube for Safari 9 users)

Thanks god it works for 720p videos

Also, I just realized the hotkeys are enabled even if you aren't using sip (you would expect it to work just when running a video). This cost me to open up and perform a deep cleaning of my Mac, wondering why E (bound as SHIT + E) didn't work lol.
