team of software professionals to develop impressive video quality enhancement algorithms running on millions PCs all over the world

шоб я так жил! big_smile

as I said before

mine Mini with pretty much the same CPU - i5-4278U - can play 1080p, staying at 75 degrees

this's with SVP enabled

tnx, added to the Wiki

> The integrated graphics aren't that bad, but interpolation on pictures of size 3300x2100 (size of the surface when using a 1680x1050 "retina" resolution) is just too much for it.

good point

>  but the svp4-maintenance.exe is missing

this's interesting

any anti virus software installed?

- try to execute "svp4-maintenance.exe" manually, will it run?
- if not, check that "svp4-maintenance.dat" file exists and is not empty (zero size)
- if it is empty or absent then copy "svp4-maintenance.dat.backup" into "svp4-maintenance.dat" and execute the .exe again

if nothing helps then re-installation is the only option

это самовнушение big_smile
при реальном действии галочки в логе будут слова про "видео интерлейсное" и "галочка включена, считаем что частота удвоена"

это не локальный файл, что ли?
тогда галочка может быть вообщ не при чем, SVP даже не знает что видео интерлейсное
что mpv про него сообщает, только то и знает

начинать надо с того, что в зависимости от того, удваивает деинтерлейс кадровую частоту или нет, надо ставить/снимать галочку в "дополнительных настройках" SVP

brrr... just missed this

see the picture

Frame size modifications are disabled for the "direct PotPlayer interface" in rev.96

SVPtube extension can handle Crunchyroll w/o Livestreamer wink

это наверное от сплиттера зависит

вот mpv открывает поток, в котором 4 видео-дорожки и 4 аудио-дорожки, и выбирает лучший из доступных
и даже дает их переключать

     Video --vid=1 'bitrate 698000' (h264)
     Video --vid=2 'bitrate 1300000' (h264)
     Video --vid=3 'bitrate 1999000' (h264)
 (+) Video --vid=4 'bitrate 3593000' (h264)
     Audio --aid=1 'bitrate 698000' (aac)
 (+) Audio --aid=2 'bitrate 1300000' (aac)
     Audio --aid=3 'bitrate 1999000' (aac)
     Audio --aid=4 'bitrate 3593000' (aac)

ffmpeg при скачивании, наверное, аналогично

а MPC-HC видит только одну аудио и одну видео дорожки

===
PotPlayer видит все дорожки и дает выбирать на лету

пример?

тыкнул наугад, "Видео Quality selection url [mp4]" открыл 720p
если убрать фильтр форматов, то отдельные разрешения доступны в формате flv

===
а со след. попытки - 288p
очень сильное колдунство! на то он и "Quality selection url" wink

(kind of) fixed in rev.96 - in case VLC reports zero source frame rate, SVP will use value from "main.setup.vlc_force_rate"

Outer lighting -> Disabled

> Every option with no check for "DXVA" worked well.
...
> I simply deleted the vo and hwdec settings from mpv's custom settings file.

bottom line it's a DXVA decoder issue with Kaby Lake drivers

Anim8

It would seem current CPUs are just not fast enough for 4k.

can't tell about 4K@Mac, but it's totally usable on Windows even with much slower hardware than yours

> I applied the "hwdec=videotoolbox-copy" but mpv still has some bad performance. I think I am giving up on mpv as VLC support seems to be much better on MAC. I can get smooth video but audio desyncs sometimes.
> I want to confirm is this the correct way to apply the arg?

nope, you should enter "--hwdec=videotoolbox-copy" in the player_args option
OR put it right into ~/.config/mpv/mpv.conf

> If almost all Apple hardware even 2016 hardware has bad incompatible processor then what was the motivation making SVP 4 Mac? I am just curious.

yours MB Air with i7-3667U can't handle 1080p because of overheating (temp >100 degrees is not good), NOT because of it's too slow
mine Mini with pretty much the same CPU - i5-4278U - can play 1080p, staying at 75 degrees

and if you read through those two URLs I gave, there's another possible flaw with recent Apple laptops

It seems that in Sierra a feature was added to make sure that the CPU doesn't overheat by throttling the processor usage for high CPU demand processes automatically.

overall I think that Apple laptops are just "too handsome" to do real job big_smile

though I don't have my own experience with them


> what was the motivation making SVP 4 Mac?
well, you know, money big_smile

fixed in rev.96

fixed in rev.97

for the reference - this's how it should be - playing FullHD on Mac mini with i5-4278U

regarding "hwdec", just tested on my Mac Mini, the following works and reduces CPU load:

hwdec=videotoolbox-copy

at which point it crashes? right after playback start, or occasionally after some time?
does it crash with any video file / any video resolution or not?
