 Summary of the bug: Any version of FFMpeg above 4.3 gives error about
 NVENC and API version. Driver does not support the required nvenc API
 version.
 How to reproduce:

 ffmpeg version
 built on ...4.3.1 and ffmpeg-N-99865-ga125e08130
 }}}

 Version 4.3.1 I get an error about API version. Driver does not support
 the required nvenc API version. Required: 10.0 Found: 9.1

 I also tried with one of the nightly builds
 ffmpeg-N-99865-ga125e08130-win64-gpl.zip and I got a different error
 Driver does not support the required nvenc API version. Required: 11.0
 Found: 9.1

 I have the latest nvidia driver for my Quadro M2000, driver version
 441.66.  This new API/driver version requirement effectively breaks
 hardware acceleration with all 5th and 6th generation Nvidia cards.
