vpp-fruc is not workling correctly

[rainman74]

Tests: --vpp-fruc double -> works and is incredibly fast ✅🚀 --vpp-fruc fps=60000/1001 -> is ignored, double is used ❌ --vpp-fruc fps=50000/1001 -> is ignored, double is used ❌ --vpp-fruc fps=50.0 -> works, but you get debug messages ❌ --vpp-fruc fps=60.0 -> works, but you get debug messages ❌

You get tons of these debug messages:

and in help output there is missing a carriage return after ...(fast):

--vpp-fruc [<param1>=<value>][,<param2>=<value>][...] enable frame rate up conversion filter. params double double frame rate (fast) fps=<int>/<int> or <float> target frame rate

Thank you for your report, fps=x/x will be fixed in next release (you can still try --vpp-fruc fps=59.94 at this time for 60000/1001).

You get tons of these debug messages:

Yes, this is unavoidable as this is coming from FRUC library (or NVOF library) and I were not able to find ways to suppress them.

Please note that fps mode ( = non double mode) is really slow as it requires re-initialization every frame, due to limitation of the library.

[rigaya]

The fps in fraction issue and the help will be fixed in NVEnc 7.44.

[rainman74]

Problem is fixed!
