How to detect Vapoursynth API version? #11

Closed Doko-Demo-Doa closed 3 years ago

Doko-Demo-Doa commented 3 years ago

In README I saw this table:

vapoursynth-api-31 for VapourSynth API 3.1 (R26)
vapoursynth-api-32 for VapourSynth API 3.2 (R27)
vapoursynth-api-33 for VapourSynth API 3.3 (R30)
vapoursynth-api-34 for VapourSynth API 3.4 (R30)
vapoursynth-api-35 for VapourSynth API 3.5 (R38)
vapoursynth-api-36 for VapourSynth API 3.6 (R47)

But all Vapoursynth versions are labeled in Rxx (e.g, R52) format, not in x.x format. How can I map them?

YaLTeR commented 3 years ago

It says in the end of every line:

vapoursynth-api-31 for VapourSynth API 3.1 (R26)
vapoursynth-api-32 for VapourSynth API 3.2 (R27)
vapoursynth-api-33 for VapourSynth API 3.3 (R30)
vapoursynth-api-34 for VapourSynth API 3.4 (R30)
vapoursynth-api-35 for VapourSynth API 3.5 (R38)
vapoursynth-api-36 for VapourSynth API 3.6 (R47)

Sorry if I wasn't clear. How can I detect VapourSynth API version? When using:

vspipe -v

with VapourSynth R52, it prints:

VapourSynth Video Processing Library
Copyright (c) 2012-2020 Fredrik Mellbin
Core R52
API R3.6
Options: -

so the API version here is 3.6, right? Does that mean VapourSynth R47 and R52 have the same API version?

YaLTeR commented 3 years ago

Yeah, the crate feature you enable indicates the lowest vapoursynth API version you want to support.

YaLTeR commented 3 years ago

Did I answer your question?

Doko-Demo-Doa commented 3 years ago

Yes, thank you very much, the only thing I need to know is whether VapourSynth R47 and R52 have the same API version or different. And the answer is "same".

Actually there is a problem with vapoursynth-rs with VapourSynth R52. Also failure crate is deprecated. But they are different issues.

Actually there is a problem with vapoursynth-rs with VapourSynth R52.

Could you make a separate issue about the problem?

Also failure crate is deprecated.

Yeah, I haven't worked on the crate in a while.
