[SOLVED] Unable to load DGDecodeNV.dll

Hi,

I just reinstalled Windows 10 1803 and DGDecodeNV won't load in Avisynth+ anymore.
I have the latest drivers so 397.64, all vc_redist x86 2008 to 2015 (tried 2017 too) installed.
I had the same error with RgTools plugin, which required the 2015 one and it works now.

Getting "code 126: The specified module could not be found." using the 32 bit version.

Not sure what I missed :?:

Edit: There's actually some errors opening DGIndexNV about nvcuvid.dll and nvcuda.dll
Probably the drivers?

Another edit: Downgraded to 391.35 and it works
NVIDIA must've done something :scratch:

Latest drivers do not support Fermi, and do not support any GPU on 32-bit OSes.

GTX 970 isn't Fermi though, and OS is 64 bit.

"There's actually some errors opening DGIndexNV about nvcuvid.dll and nvcuda.dll"

What errors?

Sorry, that they were missing, both dlls
I also noticed there's no more PhysX install with the latest drivers.

I just tried to install 397.64 on my other win10 1803 system. The driver installation failed. I'm off to check the GEForce forums. Looks like another screwed up driver. Sigh.

After removing the previous driver with the DDU utility I was able to install 397.64 successfully and DGDecNV works fine.

Here are my details:

Win 10 64 1803 (17134.48)
GTX 1050 Ti
nVidia driver 397.64
DGDecNV 2053.0.0.147

Please try again, first removing the current driver with the DDU utility.

I just did exactly the same and it works now.
Wonder if it could've been because the initial driver was from Windows install/update
Thank you :hat:

Also quick question, I managed to open a HEVC file with D3D On and CUDA decoding (option 1, from default CUVID 0) on the 970
It looks like this, I'm not sure if it will decode/index properly.

I tried indexing, it's slow (15MB/s disk usage) but shows the proper info.

If it doesn't decode properly in DGIndexNV, it won't in DGDecodeNV also.

970 has one of those goofy hybrid HEVC solutions. Why don't you sell it and get a 1050?

It's not a necessity for now.
I just tried and it does indeed say CUDA error when loaded with DGSource.
Thanks.
