Bug hunt in FillDuplicateFrames MV mode

[Selur]

Correction this is caused by mvtools!
I simplified the script to:

# Imports
import vapoursynth as vs
# getting Vapoursynth core
import sys
import os
core = vs.core
# Import scripts folder
scriptPath = 'F:/Hybrid/64bit/vsscripts'
sys.path.insert(0, os.path.abspath(scriptPath))

# loading plugins
core.std.LoadPlugin(path="F:/Hybrid/64bit/vsfilters/Support/libmvtools.dll")
core.std.LoadPlugin(path="F:/Hybrid/64bit/vsfilters/SourceFilter/LSmashSource/LSMASHSource.dll")

clip = core.lsmas.LWLibavSource(source="G:/TestClips&Co/files/test.avi", format="YUV420P8", stream_index=0, cache=0, prefer_hw=0)

sup = core.mv.Super(clip, pel=2, hpad=0, vpad=0)
bvec = core.mv.Analyse(sup, blksize=16, isb=True, chroma=True, search=3, searchparam=1)
fvec = core.mv.Analyse(sup, blksize=16, isb=False, chroma=True, search=3, searchparam=1)
clip = core.mv.FlowFPS(clip, sup, bvec, fvec, num=50, den=1, mask=2)

# output
clip.set_output()

adn calling:

VSPipe.exe c:\Users\Selur\Desktop\FillDuplicateFrames_MV_Cache.vpy NUL -c y4m

gave me:

Warning: Explicitly instantiated a Cache. This is no longer possible and the original clip has been passed through instead.
