> I thought SVP adapts to changing FPS
Yep, but not with mpv, because SVP doesn't even know about actual FPS change.
That "estimated-vf-fps" property mentioned above shows "estimated/measured FPS of the video filter chain output", i.e. after the vapoursynth filter, and since vapoursynth script have to call AssumeFPS(), estimated-vf-fps just stays fixed.
This's not our fault cause MPC-HC is a 3rd party application.
You can manually download an older version.
At which point exactly do you see this error message?
What OS are you using?
please check if this one will fix it
this's similar to that one
will be fixed in the next build
Still we do not provide you with the lifetime license in terms of the fact that our package can be used to install the program on giveaway date only. It means that you will not be able to re-install the program after PC crash or install the program on another PC after the giveaway day is over.
на таких условиях можно наверное что-то придумать...
According to our terms and conditions the software gained from GOTD can not be updated or upgraded to newer version. Some programs still check for updates – once you agree to update you lose the registered version.

причем тут вообще svplight? 
а та "подсветка", которая рисует на черных полях кадра, в углах тоже умеет - видно если включить режим "glow lights"
> 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.
как образец можно взять скрипт, который генерирует SVP 3.0 (?) (НЕ 3.1) при включенной подсветке полей, оно там как раз делалось сугубо на уровне скрипта
фигурная разрезка-ресайз-склейка
> Просто подобных BD с разным соотношением сторон не единичные случаи, и такая обработка была-бы очень полезна.
afaik, bd "с разным соотношением сторон" обычно делаются не тупой обрезкой, а более интеллектуально, т.е. кадр вырезается из разных мест полного кадра, в зависимости от сцены
> 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
Ok, here's time to run some hwdec-related tests myself
Mac Mini 2014 equipped with Core i5-4278U (2.5 GHz up to 3.0 (?)) and Iris GPU, which is definitely faster than any Core-m7.
macOS 10.12.1
Comparing CPU load with different "hwdec" values: off vs. auto-copy
SVP is OFF in all cases
1080p h264: 12% at 2.8-3.0 GHz vs. 6% at 2.5 GHz
1080p + Hi10p: 15% at 2.8-3.0 GHz in both modes
2160p h264: 35-50% at 3.0 GHz vs. 12% at 2.5 GHz
> 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...
"hwdec=auto" selects a non-"copy" decoder which isn't compatible with SVP, as a result video will remain at 24 fps while SVP won't show any error.
What you need is
hwdec=auto-copy> but even in the middle point (which was what svp suggested after running the initial test)
that "middle point" is not absolute and depends on the perf. test results 
due to your hw ...hmmm... specialty - i.e passive cooling system and very high turbo boost level - the quick benchmark may give much higher perf. level that the system can maintain on a long period of time
so you probably need to move the slider to the right from the middle position and monitor the actual CPU frequencies via Intel Power Gadget
if "SVP index" stays at 1.0 and CPU load is not higher than ~70% then your're good
> Would SVP 4 run on a 2016 MacBook with the Skylake core i7?
yes if it won't drop frequencies due to overheating
> I am considering buying the pro version but since there's no free trial or anything
there's a 1 month money back guarantee for Mac version
===
Core i7 or Core m7?
> Is it possible that your installer only creates the plugins folder if I pick one or more players?
yeah, obviously it installs only what is needed
avs 32-bit plugins <=> directshow 32-bit players
avs 64-bit plugins <=> directshow 64-bit players
vs 64-bit plugins <=> mpv || libmpv || vlc
vlc 64-bit plugin <=> vlc
luckily for you there's a per-component installation option
OK then.
It'll work in Sterescopic but you'll get a desync by several frames between left and right views
You can try it yourself by playing it in Stereoscopic Player
Most likely you'll get a desync by several frames between left and right views...
> Now I have smooth playback on everything. I am not sure it is even using SVP at this point.
nope, it probably just switches your screen to 24 hz
> How can I get HW decoding to work?
it's a good question
===
OK, found it
In recent PMP builds (>= 20 Oct 2016) we can use
"hardwareDecoding": "copy"in plexmediaplayer.conf to use hw decoder compatible with SVP
this's the previous build that was linked with 3.4m
> playback is still not smooth, even on 720p
this's different
what do you see in SVP's log and performance graphs while playing 720p?
> I am still getting the Frame server (64-bit) NOT FOUND message
restart the SVP Manager after changing PATH value
> Also, things don't look good in my log.
only thing that is not "good" here is
> [v][vd] Using software decoding.
while trying to play 4K
> I started a video and it said SVP enabled on the screen
Good for you now it's a question whether it's running with HW decoding or not.
> For anyone else having this issue, here is my recommendation.
How is this different from the wiki article?
Actually, this's interesting
PMP seems to ignore "hwdec" option given in mpv.conf, it only uses "hardware_decoding" value from plexmediaplayer.conf file.
When it's set to "true" PMP passes "hwdec=auto" to mpv engine, and it selects "best" video decoder BUT not the "*-copy" one => SVP is not working.
So we need to find the way to force some specific "hwdec" value, i.e. "hwdec=d3d11va-copy" in the PMP,
OR turn hw decoding off via plexmediaplayer.conf.
I don't like this:

Try different values for "hwdec" option:
hwdec=d3d11va-copy
hwdec=dxva2-copy
hwdec=no
And you'd better make it work with lower resolution video first.
4k playback may have other issues.
let's stick to one thread about this
