NVencC fails when using NVEnc Native/Cuda as decoder

[iamcagn]

Hi there,

Previously with 1.7.0 of Staxrip I was able to use the NVEnc Native as the decoder, reducing CPU usage for the video conversion. When I use the 1.8.2.0 release from you, I receive the following error as soon as the video conversion starts. The dll files it mentions in the error are present, so I'm unsure why it's unable to load them. Using AviSynth/VapourSynth as the decoder works as expected, just with higher CPU usage.

Any suggestions?

Upgrading NVEncC to 4.09 seems to have fixed the issue.
