not working VP9 video

Avisynth script

C:\temp\encodingTempSynthSkript_20_48_49_3710.avs

looks okay:

LoadCPlugin("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\ffms2.dll")
LoadPlugin("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\masktools2.dll")
LoadPlugin("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\ImageSequence.dll")
Import("C:\Program Files\Hybrid\32bit\avisynthPlugins\Logo.avs")
SetFilterMTMode("DEFAULT_MT_MODE", MT_MULTI_INSTANCE)
# loading source: D:\goop.mkv

Encoding call looks okay:

"C:\PROGRA~1\Hybrid\32bit\ffmpeg.exe" -y -loglevel fatal -threads 4 -i "C:\temp\encodingTempSynthSkript_20_48_49_3710.avs" -an -sn   -vf zscale=rangein=tv:range=tv -pix_fmt yuv420p -vsync 0  -f rawvideo - || "C:\PROGRA~1\Hybrid\64bit\x264.exe" --preset superfast --tune psnr --pass 1 --bitrate 1500 --profile high --level 3.1 --rc-lookahead 40 --weightp 2 --sar 1:1 --non-deterministic --range tv --stats "C:\temp\goop_20_48_49_3710_08.stats" --demuxer raw --input-res 1280x720 --input-csp i420 --input-range tv --input-depth 8 --fps 25/1 --output-depth 8 --output NUL

and looking at the debug output 227 frames get encoded (x264 output: 227 frames: 3.57 fps, 1583.51 kb/s), but then the decoder (in your case ffmpeg) crashed.
Seeing that the input has 276 my guess is that, either:
a. the source has a bug which causes FFVideoSource to crash
b. the decoding process causes Avisynth to use too much RAM
c. something else causes ffmpeg to crash

-> Assuming your source file is okay, and ffmpeg isn't using too much RAM and your system has no memory issue, try the following:

• enable 'Filtering->Avisynth->Misc->Use FFms200'
  
• if that doesn't help, enable 'Filtering->Avisynth->Misc->LibavVideoSource instead of FFmpegSource'
  
• if that doesn't help, disable 'Config->Internals->Avisynth->Prefer FFmpeg as decoder' and enable 'Config->Internals->Avisynth->Prefer avs2yuv as decoder'
  
• if that doesn't help, try using Vapoursynth instead of Avisynth
  
• if that doesn't help, share the source and the logo with me so I can try to reproduce the issue here.

enable 'Filtering->Avisynth->Misc->Use FFms200' (crashed)
if that doesn't help, enable 'Filtering->Avisynth->Misc->LibavVideoSource instead of FFmpegSource' (Successful coding)
if that doesn't help, disable 'Config->Internals->Avisynth->Prefer FFmpeg as decoder' and enable 'Config->Internals->Avisynth->Prefer avs2yuv as decoder' (crashed)
if that doesn't help, try using Vapoursynth instead of Avisynth (Successful coding)

thank you

Okay, seems like FFmpegSource is having some problems with the source.
Happy you got a solution.
