[BUG] SVT-AV1 not working with vapoursynth inputs (Arch Linux)

[Selur]

Did a quick test with a build of SvtAv1EncApp I created on Saturday (SVT-AV1 v3.0.0 (release)).
Works fine here. My build does not report all the memory related output yours does.

SvtMalloc[info]: you have no memory leak
process finished with exitcode: 0 and exitStatus: 0

I checked my logs and I did not really change any code since 2024-12-05 in regard to SvtAV1, so me using my latest dev should not be the cause of the encoding working for me.
Atm. I suspect, that it's either an issue with your SvtAV1 build (I would recommend trying 2.3.0 or 3.0.0) or with the Vapoursynth script.

=> I'll create a new SvtAv1EncApp build tomorrow and will test with that build.
