Plex for Windows does not use SVP (Page 1 of 2)

Yeah SVP for "Plex for windows" seems broken on my end as well, if SVP is open when I open plex and play a movie/tv show it will hang for a second after opening the media and crash, and will continue to crash so long as SVP is open/enabled

SVP ver: 4.5.0.200
"Plex for windows" ver: 1.23.0.1435
Plex server ver: 1.21.0.3608

Yup; picture of env variables: https://ibb.co/pP1cVx6
And yeah the mpv-1.dll was replaced
mpv.conf is also edited with:

Looking into the logs of plex for windows, mpv is recognized and running

@Chainik

- Just to rule out basic problems; I uninstalled svp & plex for windows via control panel, and reinstalled to their "standard" C:\ locations as well as re-adjusted the environment variables.

I thought I saw a note about needing to use the Plex Media Player for this to work, that web browsers won't work.  The plex download page felt confusing to me, but I assume the Plex for Windows is the server part.  But maybe you're trying to have the server do the work for any and all players?  Which would be nice.

I've got the current Windows 10 Plex Media Player version working fine using the SVP directions mentioned initially.  I've played successfully from the local server and a remote one.  I see the usual framerate green text at the start, like I do from MPC-HC for local files.

Plex for Windows used to work with SVP 4 for me, but I had to reinstall Windows from scratch. And now I can't seem to get Plex for Windows to work with SVP 4 anymore for some reason. I have followed the instructions for installation, and it works with MPC-HC and VLC, but not with Plex for Windows.

I haven't installed Plex Media Player though, since they are not updating that anymore.

Hello, are you guys working on this?

I've copied over the mpv-1.dll, set up the environment values and also the mpv.conf file.
Here is the content of mpv.conf:

input-ipc-server=mpvpipe
hwdec-codecs=all
hr-seek-framedrop=no
saturation=-100

The removal of saturation works (ie. plex is reading the configuration file) but it won't interpolate. When I open a video file locally with mpv I get interpolation as expected. I don't know what I could be doing wrong.

This is what happens when I play a file on Plex

Plex plays normally (ie. it still doesn't work) after I've deleted mpv-1.dll from the Plex folder. Yes I do have Python installed elsewhere.

These are my env variables

+1 here
I've been using SVP for over a year now... and i had to replace the plex mvp-1.dll each time the client updates (i think)
but now this seems to have change probably on plex side. so my guess is the instalation instructions need to be updated?
maybe plex is using the dll from some other folder?

i tried to contact the svp team by bug reporting via app requesting to contact me on this issue but still no answer.
With this thread i Just found out i am not the only one having this issue

-- update --
so i used process explorer to check what would be using mpv-1.dll and i can confirm plex.exe is still using the mpv-1.dll at
"c:\Program Files\Plex\Plex\mpv-1.dll"
by deleting this file is starts using the mpv-1.dll from SVP 4 folder as stated above.... but still nothing has changed at plex

so something else must be wrong

I'm using plex for windows not plex media player, and I've follow the instructions more times than i can remember, so this is something new.
I will check the logs when i have the time (currently i've been really busy, so it may take a while) and see if i can find something else
