Feature Request: add --vpp-smooth to Nvenc

[Dan64]

Hello Selur

I noted that in Nvenc it is available another denoise filter "--vpp-smooth". I was unable to find this option in Hybrid.
The syntax of the option is the following:

--vpp-smooth [<param1>=<value1>][,<param2>=<value2>],...
parameters

• quality=<int> (default=3, 1-6)
  Quality of the filter. Larger value should result in higher quality but with lower speed.
  
• qp=<int> (default=12, 1 - 63)
  Strength of the filter.
  
• prec
  Select precision.
  • auto (default)
    Use fp16 whenever it is available and will be faster, otherwise use fp32.
    
  • fp16
    Force to use fp16. x64 only.
    
  • fp32
    Force to use fp32.
    

It could be useful add it in Hybrid.

Thanks

will look into it over the weekend

fp16 is broken here.

Issue is fixed in NVEncC 5.25, build a new dev version and send you a link via pm.

Tested with Nvenc 2.25 and now the precision equal to "fp16" is working, but the encoding speed drop from 439fps to 95fps. Probably the "speed" advantage is available only on 32bit OS, but on Windows 10 64bit, precision equal to "fp32" is faster.
