Summary0000650: 'ACESS VIOLATION' crash when "image upscaling = NGU sharp" and using SVP in fullscreen
DescriptionError message: https://imgur.com/5xOxmqR [^]
Happens when I turn this on: https://i.imgur.com/QKjBqNZ.png [^]
FFMPEG tooltip info: https://imgur.com/Fo98flk [^]

The playback always crashes, almost instantly when certain MadVR settings are on.
Seems to only happen when I have SVP on (SmoothVideoProject 4.0.0-6), I'm using MPC-HC 64-bit 1.9.6 and madVR 0.92.17.

This might be a SVP bug, but seems to be directly affected by madVR. I downloaded madVR and MPC-HC through the SVP mainteinance tool.

Seems related to http://bugs.madshi.net/view.php?id=527 [^]
Steps To ReproduceThe bug seems to only happen if I meet all 3 of the following requirements:
- Have SVP on (performing frame rate conversion)
- Have MPC-HC on a big window so upscaling kicks in (for example, fullscreen a 720p video)
- Have "Image Upscaling" set to "NGU Sharp" in settings
- Might only happen on my CPU/GPU setup (but probably affects all/most setups), can't test.

Closing SVP, watching in windowed mode, or changing Image Upscaling to Jinc either greatly lowers the chance for the crash to happen (like from 99% per second to 1%) or fully stops it (didn't test for long periods of time).

I'm a basic user, I don't know what the decoding, splitter and decoder fields below are, I hope I typed the right thing but probably not. Don't know how to check.

The website duplicated my other issue ( http://bugs.madshi.net/view.php?id=651 [^] ). I tried to upload a text file, it said it wasnt published because .txt was invalid and asked me to press back on my browser and change it. I made minor changes to this bug report and submitted again, but then realized the website published both for some reason.

Your GPU has rather little RAM, maybe that's causing the issue? I'm not sure, just guessing. You could try lowering the size of the CPU Queue and GPU Queue settings in the madVR settings under "rendering -> general settings".

Nope, GPU Queue at minimum (4) and CPU Queue at 8 (half the default, cause my CPU is decent) and it still crashes if I set Chroma Upscaling and Image Upscaling to something complex/heavy (maxed out NGU).
This time, it became a slideshow for a few seconds (MPC almost crashing, displaying 1 frame per second) and then crashed with the same error.
Using Jinc on both still works fine
