[BUG] Crash when encoding

[The_Tinkerer]

Just got time for testing Interframe with AviSynth in dev version 2020.06.28.1. Unfortunately, it crashes.

AviSynth script:

ClearAutoloadDirs()
LoadCPlugin("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\ffms2.dll")
LoadPlugin("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\svpflow1.dll")
LoadPlugin("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\svpflow2.dll")
Import("C:\Program Files\Hybrid\32bit\avisynthPlugins\InterFrame2.avsi")
SetFilterMTMode("DEFAULT_MT_MODE", MT_MULTI_INSTANCE)
# loading source: E:\USER\fin\Test\Test.mp4
#  input color sampling YV12@8, matrix:Rec.601, scantyp: progressive
#  input luminance scale tv
FFVideoSource("E:\USER\fin\Test\Test.mp4",colorspace="YV12")
# current resolution: 656x480
InterFrame(NewNum=60000,NewDen=1001,OverrideAlgo=23,Tuning="Weak",Cores=16)
# filtering
PreFetch(4)
return last

Debug file attached!

I tried with Vapoursynth, and I seem to have the same symptoms as the original poster. After 100%, the processing continues as the processing speed increases (the fps in the title bar gradually continues to go up) and the file size gradually continues to decrease. I stopped it at 2000%.

Vapoursynth script:

# Imports
import os
import sys
import vapoursynth as vs
core = vs.get_core()
# Import scripts folder
scriptPath = 'C:/Program Files/Hybrid/64bit/vsscripts'
sys.path.append(os.path.abspath(scriptPath))
# Loading Plugins
core.std.LoadPlugin(path="C:/Program Files/Hybrid/64bit/vsfilters/FrameFilter/Interframe/svpflow2_vs64.dll")
core.std.LoadPlugin(path="C:/Program Files/Hybrid/64bit/vsfilters/FrameFilter/Interframe/svpflow1_vs64.dll")
core.std.LoadPlugin(path="C:/Program Files/Hybrid/64bit/vsfilters/SourceFilter/LSmashSource/vslsmashsource.dll")
# Import scripts
import havsfunc
# input color space: YUV420P8, bit depth: 8, resolution: 656x480, fps: 25
# Loading E:\USER\fin\Test\Test.mp4 using LibavSMASHSource
clip = core.lsmas.LibavSMASHSource(source="E:/USER/fin/Test/Test.mp4",fpsnum=25)
# making sure input color matrix is set as 470bg
clip = core.resize.Point(clip, matrix_in_s="470bg",range_s="limited")
# making sure frame rate is set to 25
clip = core.std.AssumeFPS(clip, fpsnum=25, fpsden=1)
# Setting color range to TV (limited) range.
clip = core.std.SetFrameProp(clip=clip, prop="_ColorRange", intval=1)
# adjusting frame count with Interframe/SVP
clip = havsfunc.InterFrame(clip, Tuning="weak", NewNum=60000, NewDen=1001, OverrideAlgo=23) # new fps: 59.94
# Output
clip.set_output()

In troubleshooting the AviSynth crash, I found it seems to be related to the versions of svpflow1.dll and svpflow2.dll in the avisynthPlugins directory.

I replaced the versions that Hybrid 2020.06.28.1 installed (same as release version 2020.06.21.1):

CRC32            Size  Name
-------- -------------  ------------
E66573AE        374784  svpflow1.dll
6A7C9596        399360  svpflow2.dll

...with the older versions that were installed with Hybrid 2020.02.19.1:

CRC32            Size  Name
-------- -------------  ------------
0586759C        517632  svpflow1.dll
ABA31676        647680  svpflow2.dll

Now Hybrid works as expected without crashing.

Debug file of successful run with the older svpflow dll's attached!
