VapourSynth: R63 seems to be the last release for Win32; and it even fails

[LigH-de]

Error 404 while downloading https://github.com/vapoursynth/vapoursynth/releases/download/R65/VapourSynth32-Portable-R65.7z

No more Win32 release after R63.

So may VapourSynth support in ffmpeg have to be disabled for the 32 bit branch? Or would it still work with R63?

You seem to prefer abandoning the whole Win32 compilation for every tool anyway...

[1480c1]

I presume the wrapper would work with r63, so should be easy enough to do something like if [[ $bits == 32bit ]]; then _vsver=r63... or something and limit 32-bit to r63. I do not know what is the latest python that 32-bit supports, though, do you?

[hydra3333]

I looked at the vapoursynth git and release R62 notes say

updated the supported python versions to 3.11

so R63 would be 3.11.7 I checked python.org and 3.11.7 has 32 bit download.

cheers

[1480c1]

@LigH-de can you try https://github.com/1480c1/media-autobuild_suite/tree/vp32 and see if you can make sure the vapoursynth works there? I'm fine with “pinning” projects for 32-bit to their last known version as long as we know it works at that version.

In the future, I may see about making it work better, instead of just hard-coding if [[ $bits = 32bit ]]; then .. else ... fi

[LigH-de]

Yes, vp32 branch downloads R63; ffmpeg got compiled. To check if it actually works, I hope @Selur can check that quickly or give me some advice about the prerequisites...

[Selur]

I never really used Vapoursynth 32bit, so can't advice on it. In Hybrid, only 32bit tools are:

• neroAacEnc, fhgaacenc, CUETools.FLACCL (since there are no 64bit versions)
• mencoder&mplayer, ffmpeg, ffmbc to use with Avisynth 32bit

[hydra3333]

give me some advice about the prerequisites...

IIRC, without using installers (everything portable): extract portable (embedded) python 3.11.7 32bit into a folder extract vapoursynth R63 (portable) 32bit into the same folder pop the new ffmpeg 32bit into the same folder install any filters (eg using vsrepo) and dgsource/dgindex if you use that run ffmpeg with -f vapoursynth -i "input_script.vpy" ...

here's an example from a test script I just used.

I tested the freshly built ffmpeg with the following script:

version.vpy

import vapoursynth as vs
core = vs.core
clip = core.std.BlankClip(format=vs.RGB24, color=[0, 0, 0])
c = core.text.CoreInfo(clip)
c.set_output()

VapourSynth recognises it: VSPipe.exe --info version.vpy

Apparently, ffmpeg accepts it. But it prints only its configuration, then quits. Same for ffprobe and ffplay. ffplay.exe -f vapoursynth version.vpy

@LigH-de So, R63+3.11.7 doesn't work? Do you know of an older combination that does work?

[LigH-de]

I never really used it before, only noticed that building started failing. And then noticed that the Win32 build does not even really work. The way how it does not respond is interesting, though, and I neither know how to debug it nor who to contact about it with sufficient competence regarding communication between ffmpeg's modules.

If I can simply try it by unpacking different Python and VapourSynth portable archives to the same ffmpeg exe, I can test some. But if I would have to compile the ffmpeg matching to each of these combinations, I would not have the time and will...

I hoped that Selur may have preferred using ffmpeg with direct VapourSynth support inside Hybrid. Another hope may be StaxRip maintainers. But if they all relied on piping, they will not know either.

[1480c1]

Some news, attempting the same thing you did before results in ffplay segfaulting in read_header_vs() in vapoursynth.c, specifically

    if (!vsscript_init()) {

unfortunately, I do not know enough about vapoursynth to be able to figure out anything further.

[LigH-de]

In the doom9 forum, @Selur wrote:

Older Vapoursynth doesn't work with Python 3.11, try Python 3.8 instead.

So I tried unpacking python-3.8.0-embed-win32 and VapourSynth32-Portable-R63 into one directory with ffmpeg; unfortunately, the same result: No output after the version string.

Does the compilation process of ffmpeg with native VapourSynth input support depend on the Python and VapourSynth libraries and headers versions present during the compilation?

PS: Python 3.8.10 seems to be the last v3.8 release with embeddable Win32 binaries. But no output either.

[Selur]

I think something is amiss with the Vapoursynth 32bit portable, since creating a directory, extracting python-3.8.0-embed-win32.zip and then VapourSynth32-Portable-R63.7z into it should at least give an output for 'VSPipe.exe --version', but that already shows 'Failed to initialize VSScript' (doesn't work with R62-54 either) With R54, just calling VSPipe.exe shows the help of VSPipe, but VSPipe.exe --version fails too. => this seems broken to me

[LigH-de]

So it seems it has been broken for a long time already. But nobody used it in 32 bit so nobody noticed that.

Limiting the building of VapourSynth enabled ffmpeg to 64 bit may not hurt anyone then...

[Selur]

Limiting the building of VapourSynth enabled ffmpeg to 64 bit may not hurt anyone then...

True. :)

[1480c1]

So, the consensus would be to just disable vapoursynth for 32-bit? At least until someone is able to figure out the last working version?

[1480c1]

New commit changes the output to for 32-bit
