How to run Avisynth scripts within VapourSynth

[Stephen R. Savage]

README:

Embed 32-bit Avisynth 2.6 or Avisynth+ environment within 64-bit VapourSynth.

avsw.Eval(string script, clip[] "clips", string[] "clip_names", string "avisynth", string "slave", string "slave_log")

script - Avisynth script fragment
clips - VapourSynth clips ("nodes") to inject into Avisynth environment
clip_names - Avisynth variable name corresponding to injected clip
avisynth - Path to Avisynth DLL. The default uses the process DLL search path.
slave - Path to avshost_native.exe slave procecss. The plugin path is searched by default.
slave_log - Log file for slave process.

The function returns the result of the Avisynth script, which may be an integer, float, string, or clip. If the result is a clip, the name of the return value is "clip", otherwise it is "result".

Example:

import vapoursynth as vs

core = vs.get_core()

red = core.std.BlankClip(color=[255, 0, 0])
green = core.std.BlankClip(color=[0, 255, 0])
# Before executing the Avisynth script, "r" and "g" are set to the bound clips.
c = core.avsw.Eval("Merge(r, g)", clips=[red, green], clip_names=["r", "g"])
c.set_output()

Link.

NICE!!

c = core.std.BlankClip(color=[255, 0, 0])
c = core.avsw.eval('AddAutoloadDir("D:\\AvisynthRepository\\SCRIPTS") mpeg2source("D:\\01.d2v") AnimeIVTC(mode=1)', clips=[c], clip_names=["last"])
clip=c

This avs script crashed via Avisource and with avfs.exe, but avsproxy is stable.

Two questions:
- Is it possible to use avisynth x64 with this filter?
- Would be a "portable" avisynth possible as long as avisynth.dll is in the same folder? (or via path parameter in avsw)

You can load 64-bit plugins directly. It looks like your script does not need the clip binding feature, so you should be able to use VFW.

You can provide the Avisynth library path via "avisynth" argument (link in original post updated).

Holy smoke, thank you very much! I've been waiting to get my hands on SmoothD2 in 64-bit Vapoursynth since we are still waiting for a proper port, and with this tool, it's possible

But I can't load avs scripts directly ( AnimeIVTC is a script )
And loading my sample script via VFW aka Avisource is not possible -> instant crash in VS ( No problems in Virtualdub-64). That's why I asked if x64 would possible.

Instant crash? Does it output any error like bad mmx state if you try to output it with vspipe?

[ChaosKing]

No output. Tested like this with R41-test4

.\VSPipe.exe -i 'D:\Test.vpy' .

My vs script

clip = core.avisource.AVISource(r'D:\ivtc.avs')
clip.set_output()

But it works without tfm or animeivtc.

AddAutoloadDir("D:\AvisynthRepository\SCRIPTS")
mpeg2source("D:\01\VTS_01_CHAPTER_03_1.d2v")
tfm(mode=6, PP=5,  slow =2, d2v="D:\01\VTS_01_CHAPTER_03_1.d2v") <- bad boy

But this forced me to switch to vivtc, and after some conditionalDeintStillCombed magic I got similar/better results.

Can you put all the scripts and a sample script and the plugins into an archive? That way I can test with the same versions as you and don't need to go on a treasure hunt. And reveal your avisynth version too while you're at it. I'd really like to get to the bottom of this...

Here is my x64 r2544 avs folder (plugins, scripts & sample script)

//EDIT
Same crash with r2580

[ChaosKing]

Thx, woking now. Loading an external avisynth.dll too!

I found one crash in avisource. Try it again when I release the next R41 build.

At least we're making progress. It happens because of a bug in one of the avisynth plugins. Comment out the script gradually and locate which one it is. Someone forgot to use the emms instruction. Find the plugin author and shame them, or update to the latest version of whatever plugin it is.

[ChaosKing]

Working now. I had an old x64 TIVTC.dll from 2010, don't know why :-/
No problems with: https://github.com/pinterf/TIVTC/releases

EDIT: I guess I took it from this (outdated) list http://avisynth.nl/index.php/AviSynth%2B_x64_plugins

EDIT2: But it's still interessting that it only crashes in VS and not in VdubMod

[ChaosKing]

I should be able to pass a VS clip to Avisynth, right?

Because this works

c = core.avsw.eval('blankclip() Subtitle("Hello world!") ')

but not this

c = core.std.BlankClip(color=[255, 0, 0])
c = core.avsw.eval('Subtitle("Hello world!") ', clips=[c], clip_names=["last"])

vapoursynth.Error: Avisynth 32-bit proxy: command failed

[ChaosKing]

The original from Soureforge works, also 2.6 (MT) from here https://forum.doom9.org/showthread.php?t=148782

But the colors are shifted https://www.dropbox.com/s/7lft4ek963...color.PNG?dl=0

AVS+ would be nice for 16bit support (if possible)

[ChaosKing]

I totally forgot about stack16, thanks for the reminder!

Found a new issue:
I tried CropResize from here https://forum.doom9.org/showthread.php?t=175114 with Autocrop, but it gets stuck. Without AutoC=true it's ok. There's no output in vspipe. tested with avs+ and 2.6

core.avsw.Eval('AddAutoloadDir("D:\AvisynthRepository\SCRIPTS") pCropResize(AutoC=true)', clips=[c], clip_names=["last"], slave_log=r"D:\x.txt", avisynth =r"D:\AvisynthRepository\AVSPLUS_x86\Avisynth.dll")

[observe @ :376] load avisynth DLL from 'D:\AvisynthRepository\AVSPLUS_x86\Avisynth.dll'

[ChaosKing]

Works flawlessly

EDIT: currently an avs error msg is not show like in virtualdub (or any other tool). It would be nice to see the actual avs error rather than "vapoursynth.Error: Avisynth 32-bit proxy: command failed". It's a nice to have feature (and if it isn't too hard to implement)

What does this error actually mean? I was trying to test this script and got the message. The sample script from the first post works fine.

import vapoursynth as vs

core = vs.get_core()
core.avs.LoadPlugin(r'C:\\Program Files\\VapourSynth\\avs64\DGDecodeNV.dll')

c = core.avs.DGSource(r'C:\Temp\test.dgi')

clp = core.avsw.eval('SmoothD2(quant=2, shift=4)', clips=[c], clip_names=["last"])

clp.set_output()
