Pulling my hair out, cannot get any encodes to start.

[frencoder]

Hello, I was recommended Hybrid+Vapoursynth by a friend, but I cannot get an encode to start, it fails at saying the xxxx.x264 is too small with 0 bytes

This was on the last version I was trying 2020/05
https://del.dog/hybrid.txt

With version 2020/6/21
Same thing.

I really want this to work, I even tried it on windows and got the same error with the same settings. Any details, debugging or whatever you need from me to make this work, I will do.

Thank you! I hope I'm missing something small.

Okay.
According to the debug ouput processing the Vapoursynth script fails.
And since I only look at the debug outputs of the latest release, that's as far as I go there.

My advice would be to:
a. uninstall the old Hybrid Verison and all it's files
b. since you are on a Debian based system, use the latest Hybrid Linux64bit package (with base tools and most dependencies).
c. use https://github.com/Selur/hybrid-vapoursynth-addon to setup Vapoursynth
d. before starting an encoding, check that the Vapoursynth Preview works
If the Vapoursynth Preview fails, it should show some error which might help to figure out what is going wrong.
If you use the latest version and the Vapoursynth Preview does work, try encoding again and in case it fails, create a debug output level 9 of the job processing.

My guess is that the problem is the Vapoursynth setup and the usage of 'vsfilters_env.sh' which was removed in newer versions, which is why you should make sure to remove Hybrid and Vapoursynth completely.

Wow that was fast. Okay I will do that right away.

Still no dice.

Tells me xxx.stats was not created. I do see an error in the log 

y4m [error] bad sequence header magic

[frencoder]

Okay, I figured out that using any Vapoursynth filters causes the crash.

[frencoder]

Just tried the same exact thing on windows, same behavior with the same files, latest version.

fails with:

y4m [error]: bad sequence header magic
x264 [error]: could not open input file `-'

which indicates a problem with the decoding.

Vapoursynth problems might be due to a bug in the Vapoursynth script, a problem with reading or decoding the source or something totally different.

-> Basically the same request as before: Check the Vapoursynth Preview.

On my fresh Windows install of the 2020.06.21.1 version I tracked this down to the Vapoursynth script trying to load neo-fft3d.dll (although I don't think I was using it), but the /64bit/vsfilters/DenoiseFilter/NEO_FFT3DFilter did not exist. When I manually added the folder and file I then had havsfunc (for QTGMC) fail at line 1258 because it was trying to load FFT3DFilter, which was not being loaded in the Vapoursynth script. So Under Filtering > Vapoursynth > Custom I added a core.std.LoadPlugin command to load the /64bit/vsfilters/DenoiseFilter/FFT3DFilter/fft3dfilter.dll plugin. Then the encoder ran fine with the Vapoursynth processing.

[Selur]

Argh,.. I forgot to add NEO_FFT3DFilter to the installer.
Sorry.
