[BUG] AviSynth64 does not work for encode / jobs (but viewer works)

[The_Tinkerer]

Tried in the latest development build I have, 2021.06.08.1. Tried on both Windows 7 and Windows 10 systems. Same problem and errors.

The AviSynth64 viewer works.

But, encodes crash immediately:

Creating job for current source -> Creating jobs for source: (1) -> Generating calls for: E:\USER\fin\joga\test64.mp4   adding x264 calls for source: 1   createJobs for E:\USER\fin\joga\test64.mp4   creating attachment extraction subjobs   creating video subjobs   creating muxing subjobs   optimizing the subJobs -> finished creating subjobs for current source   added new job with id 2021-07-09@21_40_53_4610 starting 2021-07-09@21_40_53_4610_02_video@21:40:53.471 - E:\USER\fin\joga\test64.mp4 2021-07-09@21_40_53_4610_02_video finished after 00:00:00.063 -> 2021-07-09@21_40_53_4610_02_video crashed: ERROR: C:\Users\ADMINI~1\AppData\Local\Temp\2021-07-09@21_40_53_4610_02.264 is too small!

The above error happens regardless if filters are used. I removed all filters and still got the crash.

Script:

ClearAutoloadDirs() SetFilterMTMode("DEFAULT_MT_MODE", MT_MULTI_INSTANCE) LoadPlugin("C:\PROGRA~1\Hybrid\64bit\Avisynth\AVISYN~1\ImageSeq.dll") # loading source: E:\USER\fin\joga\Proteus2\%06d.png # color sampling RGB24@8, matrix: bt709, scantyp: progressive, luminance scale: limited ImageReader(file="E:\USER\fin\joga\Proteus2\%06d.png", start=0, end=4837, fps=25, use_DeviL=true, pixel_type="RGB") # current resolution: 2624x1920 # filtering # adjust color to YV12 (color matrix: Rec709) ConvertToYV12(matrix="Rec709") PreFetch(8) # setting output fps to 25.000fps AssumeFPS(25,1) #  output: color sampling YV12@8, matrix: bt709, scantyp: progressive, luminance scale: limited return last
