@Chainik Yep that file seems to have fixed the issue been running it for 6 hours now and no sign of ffdshow in the event log and no windows explorer crash! I will report back if an issue arise but for now it's very promising! thank you smile

complete reinstall of the svp 4 pro.
Open svp4pro leaving it open in the tray , go play a game with browser open watching a stream

as you can see there's about a 1 hour and 20 minutes between me playing a video , closing it , leaving SVP 4 PRO opened on the tray and this crash happens.
Also no idea why FFDSHOW shows up there saying it "removed an instance" it's 100% uninstalled from anywhere on my PC

19:20:26.889 [W]: FFDShow: can't find 64-bit installation

just crashed again after typing this, while searching my pc for traces of FFDSHOW anywhere

Hope these logs helps you out.

Okay so from my Understanding... you CANNOT have svp4pro do it's magic without FFDSHOW.
If i don't use [DS_64] Core for DirectShow 64-bit , it doesn't work. <-- this is part of ffdshow
If i don't use [DS_32][DS_64] AviSynth Filter (AVSF) it doesn't work. <-- DS_32 is used here , it installs FFDSHOW 32 bit somewhere , which doesn't show up on windows add or remove program, but it's present in the EVENT LOG of svp 4 pro.
without those 2 DirectShow ffdshow related "core and 3rd party" the software just doesn't work.
and of course on W11 ffdshow crashes windows explorer.
This is just great.

Is there an alternative?

ffdshow is uninstalled from windows add or remove programs
ffdshow is removed in the additional component on svp 4 pro app
ffdshow is removed from my video player of choice MPC-HC

Using google chrome as a browser, windows explorer crashes while watching youtube videos , while watching a twitch stream with svp 4 pro app opened in the tray icon.
I use RoundedTB on windows 11 , i thought at first it was RoundedTB the issue, but after further investigation (IE uninstalling anything related to RoundedTB) closing ANY other apps besides SVP 4 Pro the crash appeard again.
It only crashes when i have SVP 4 Pro open in the tray , sometimes it can crash within 5 minutes , sometimes it can crash after a few hours , crashing is always present...
it's not just related to watching videos on a browser , it just helps make the crash appear sooner than later. Other apps that helps create the crash sooner than later are Steam and Discord.

Is there a way i can see crash logs of windows explorer or svp 4 pro reporting conflict or something so i can post them here ? Windows event viewer doesn't report any error when the crash/restart happens.


System Spec
AMD Ryzen 7 3700x
Asus x570- Pro
16gb Gskillz 3600mhz ram
Sapphire 5600XT
Virtualization is enabled in BIOS
No anti virus beside windows
no apps running beside RoundedTB which is not the culprit and svp 4 pro

Are we to be expecting an update to svp 4 pro for windows 11 to fix the windows explorer crash/reset ?

In the other topic around this you mentioned it was related to FFDSHOW and / or microsoft having issues and microsoft should be the one to fix it not you... Which seems strange as no other app or program are affected by this so called "microsoft issue" besides SVP 4 PRO.

Steps to reproduce: Windows 11 -> dual monitor setup -> launch svp 4 pro -> watch videos on your favourite browser -> wait x amount of time -> windows explorer will crash / restart.
with svp 4 pro not opened in the tray icon there is no crash related to windows explorer at all.

I've sent a report of this issue to microsoft feedback hub.

windows 11 HOME OS build 22000.282 (upgrade from win 10 to win 11 via windows update)
Issue of windows explorer crashing when using SVP 4 Pro + SVPTube with FFDSHOW uninstalled remains.
Literally had it crashed within 10 mins of uninstalling ffdshow and switching to avisynth instead.

Could be related to SVPTube, my hunch tells me it's related to SVPTube "Monitor Clipboard", haven't had a crash yet since i unchecked that option. Been an hour or so.
Will update if it changes.
I have bad memory so i can't tell if windows explorer crashed with svp 4 pro + svtube opened or not... I guess ill try to pay more attention and update on that aswell...

Edit: with Monitor Clipboard unchecked and ffdshow uninstalled , windows explorer crashed.
Edit2: SVPTube disabled in the extensions & ffdshow uninstalled but SVP 4 PRO still active does indeed crash windows explorer. ran 2 days without svp 4 pro and no windows explorer crashes.

There's definately something wrong with SVP 4 PRO on windows 11 and you guys should look into it. Yes microsoft may have changed something related to the issue at hand , but only your software creates this behavior , so your software is at fault. Microsoft ain't going to "fix" it's code so that your software doesn't crash windows explorer.
