Using a Geforce GTX 980 Ti on Windows 10 64bit with DGDecNV version 2052 (also tried 2051, 2050, 2049) 32bit I got the following problem:
When I start the DGDecNV.exe I get:
Code: Select all
ERROR: Failed to create CUDA context (999)
Hit Yes to continue notifying this specific error type; hit No to disable it.
Hit Cancel to suppress all further errors.
- deleting my DGDecIndex.ini file didn't help
- setting 'UseD3D' to 1 changed the error to 'ERROR: Failed to find CUDA-compatible D3D device.'
- doing a clean driver install (resetting settings) didn't help (using NVIDIA driver version 378.49)
- extracting DGDecNV into it's own folder away from any other dlls didn't helpt
Funny thing is that when I use the 64bit DGDecNV.exe the problem does not occur.deviceQuery.exe Starting...

Creating the index file with the 64bit version and using the 32bit DGDecodeNV.dll and in Avisynth 32bit
Gives me first:
thencuCtxCreate() failed.
and then a green screen with 'CUDA error!' in the left upper corner.Failed to create video decoder (201).
Using Avisynth+ 64bit with 64bit DGDecNV.exe to generate the index file and using 64bit DGDecodeNV.dll during decoding works.
=> seems like only the 32bit version is having this issue.
Since I didn't have a problem with the older versions before and the 64bit version does work, I was wondering are you aware of any changes on NVIDIAs driver side that might cause problems with DGDecNV 32bit version? (Did NVIDIA may be drop 32bit support o 64bit sytems?)
Any thought on how to better trace the problem or ways to fix this are welcomed.
(not planning to use Avisynth+ 64bit or Aviynth 64bit)
