NVEnc failing with a 'getWorkSurf' - I'm stumped

[Selur]

INPUT: failed to get work surface for input.

Usually happens if:
a. there is no active device connected to the NVIDIA card
or
b. there is some driver issue with the used version.
or
c. another tool uses the graphic card while restricting the usage for others

I went looking for anything about that error message, and landed on a Japanese blog about QSVEnc. Updated that in the Hybrid folder but to no change.

QSVEncC is for Intel cards. (VCEEncC for AMD cards)
Latest NVEncC is available over at https://github.com/rigaya/NVEnc.

Normally. I would recommend:

• try the latest dev, it usually comes with the latest NVEncC.
  
• if it happened after a Hybrid update and updating your drivers doesn't help, try older NVEncC versions. (NVEncC64 needs to be renamed to NVEncC)
  
• if it happened suddenly, restart your system and also check that you close other tools which might use the grahic card (especially stuff that messes with Windows themes etc.)
  
• try the current Studio drivers, since the gaming drivers sometimes have broken encoding in the past
  

Since the encoding does start and then suddenly stops, I would first try the latest dev (there were a few NVEnc updates in recent weeks) and if that doesn't help, check if something is interfering by closing other programs while testing.
