ok, PMP by default works with a OpenGL output only, which doesn't support true HDR mode but only does tonemapping to SDR
but there's a trick big_smile

plexmediaplayer.conf -> "video" -> "debug.force_vo" = "gpu"

after that it will play in an external D3D window (note that video is playing in a popup window while all the controls remains in the main window big_smile)

but it still doesn't want to switch to HDR mode, dunno why hmm

===
upd: it doesn't work because PlexMediaPlayer.exe doesn't have bloody Windows 10 manifest attached big_smile

the magic DIY command (needs mt.exe from Windows SDK):

mt.exe -nologo -manifest "d:\PlexMediaPlayer.exe.manifest" -outputresource:"d:\PlexMediaPlayer.exe;#1"

I'd say this is because the source quality is awful, it looks like the _real_ source was @10 fps, and in this one you have every 2nd frame duplicated and every 3rd frame - blended with the next one, like this: 1 - 1 - 1/2 - 2 - 2 - 2/3 - 3 - 3 - 3/4 - and so on

> да и какая разница какой телевизор и сколько кадров

такая разница что если на входе может быть только 60, то подавать туда 90 и жаловаться на "не плавно" - не надо

у mpv есть проблемы с высокой частотой кадров на 4к, до недавнего времени на нем и 4к @60 не работало, не то что 90


> А для чего тогда включать поддержку расчета кадров на gpu если вся нагрузка идет на процессор

очевидно для того чтобы сократить нагрузку на процессор

И вообще, тормозит - значит надо снизить параметры.
У меня на райзен 1700 в "авто" режиме, если выбирается 3-й профиль  - "19:16:17.541 []: Profile: using automatic profile #3 /film" - то не "тормозит", а если второй - то уже "тормозит" (23.976*4 = 95.9 fps)

Прямо ж в описании нового релиза и написано:

Due to the more strict security requirement of notarization, it cannot load dylibs automatically from your system path anymore. This might be a breaking change if you previously use your custom mpv build by only deleting the libmpv.1.dylib from IINA's package. Since IINA 1.0.5, you must copy the custom libmpv.1.dylib to IINA.app/Contents/Frameworks, replacing the original one.

SVAnalyse works only with 420p8, SVSmoothFps can render in 420p10 - see SVP-generated script for 10-bit processing.
But there're no known ways to preserve HDR metadata. However you can pass static (i.e. HDR10 w/o "plus") data to x265 manually.

more likely the problem is not in the file
can you play smoothly some other 60 fps FullHD video?

ну так в nvof только один параметр "качество" и есть

ещё можно размером блоков играть (хотя это не честный "размер блоков", сам nvof работает только с 4*4, т.е. тут увеличение блока делается за счёт уменьшения кадра по которому nvof ищет вектора)

svp's build is from 2019-11-28 while "hdr update" was merged into mpv-git on 2019-10-30

vo=gpu
gpu-api=d3d11

and these are the defaults, but Plex may override them somehow

I can't check Plex+HDR right now, but that HDR update in mpv works only with d3d11 output selected. In all other cases out will do hdr-to-sdr tone mapping.

что за телевизор может принимать 4k@ 90 fps на входе?

какой плеер, какой рендерер? следует использовать MPC-HC + madVR (64 бита)

> но загрузка процессора при этом на 50%

"50%" для процессора с HT вполне может означать практически затык
отключите HT, увидите реальную загрузку, если ближе к 90% - так уже перебор

It should work, at least it works on Windows...
If you run actual video in mpv with SVP it'll give more verbose error code.

nope because every >= 2200 px video matches two profiles

you can set conditions for the 2nd profile like this: ("hdr") OR ("not hdr" + "width>3800")
