Vapoursynth

[Yomiko]

I see. That's a nice excuse to not enumerating all the output nodes.

[lansing]

How do I pass in multiple nodes into a map programmatically for plugin such as StackHorizontal? Like this?


vsapi->mapConsumeNode(pArgumentMap, "clips", A_node, maAppend);
vsapi->mapConsumeNode(pArgumentMap, "clips", B_node, maAppend);
vsapi->mapConsumeNode(pArgumentMap, "clips", C_node, maAppend);

auto resultMap = vsapi->invoke(pStdPlugin, "StackHorizontal", pArgumentMap);

Every year I'm dealing with the same installation issues:

It only works on the Python prompt:

I used the above back wit API3 and there iirc it worked fine. (https://forum.doom9.org/showthread.php?t=175098)
My guess is that something changed in API4 which I'm not aware of.

-> Does anyone know how to load one script inside another ?

Cu Selur

[quietvoid]

I think it's because you're using the parent script's vs module (which uses another core?).
This works for both API3/API4 compatibility:


output = SourceFileLoader('script', filepath).load_module().vs.get_output()

try:
if isinstance(output, vs.VideoOutputTuple):
clip = output.clip
else:
clip = output
except AttributeError:
clip = output


Because API4 is returning a clip + alpha tuple.

[_Al_]

To get clips fro vapoursynth scripts you can use this:

import vapoursynth as vs
from vapoursynth import core
from importlib.machinery import SourceFileLoader
from pathlib import Path

API4 = vs.__api_version__.api_major >= 4

class NoClipError(Exception):
pass

def vs_Source(script_path, wanted_output=None, **kwargs):
'''if no wanted_output is passed it returns first available'''
vs.clear_outputs()
vs_found_outputs = list(SourceFileLoader('script', script_path).load_module().vs.get_outputs().keys())

if not vs_found_outputs:
vs_output_index = wanted_output
raise NoClipError(f'No output found in "{Path(script_path).name}", clip.set_output() needs to be added to the script')
if wanted_output is None:
first_output = next(iter(vs.get_outputs()))
clip = vs.get_output(first_output)[0] if API4 else vs.get_output(first_output)
vs_output_index = first_output
else:
try:
clip = vs.get_output(wanted_output)[0] if API4 else vs.get_output(wanted_output)
except KeyError:
raise NoClipError(f'Output index {wanted_output} not found in "{Path(script_path).name}"')
vs_output_index = wanted_output

#optional, writing output index and all available outputs to clips prop
if API4:
clip = clip.std.SetFrameProps(vs_found_outputs=vs_found_outputs)
clip = clip.std.SetFrameProps(vs_output_index=vs_output_index)
else:
clip = clip.std.SetFrameProp(prop="vs_found_outputs", data=','.join(list(map(str,vs_found_outputs))))
clip = clip.std.SetFrameProp(prop="vs_output_index", intval=vs_output_index)
return clip

script_path = 'C:/Users/Selur/Desktop/small.vpy'
clip = vs_Source(script_path)
because of API4 changes (vs.get_outputs(), f.get_read_array(), SetFrameProps(allows to store a list now, perhaps other python objects), it is a good idea to have on top of script boolean what API is used and then split action, vs.get_outputs() was mentioned, then frame array example:
if API4: planes =[f[i] for i in range(f.format.num_planes)]
else: planes =[f.get_read_array(i) for i in range(f.format.num_planes)]

[Selur]

Thanks! That works fine, since I only use API4 I'll stick with quietvvoids solution. :)

[ChaosKing]

There's an api3-api4 bridge now for older VS versions.
Suppose you are stuck with VS R54, but you want to use a video plugin filter.dll that only has api4 support.
You can download the released api3.dll and save it as filter.api3.dll along side with filter.dll into VS plugins directory.
And then you should be able to use the filter in api3 VS as usual.

Yes, like that, clip output must be set always to zero, or as a default clip.set_output().
If it is an unknown script,
-video output could be put in a different index, or as happens all the time to me, actually forgetting to set output, so it should take care of that , not to crash python.
-check if it is audio actually, not video,

Is there a way to figure out video-audio pairing from outputs, or can user "mark" it somehow that an audio output matches what video output?
There should be something to mark those outputs as a pair. Is there something like that?

So far for example there could be output like this(2 video outputs and one audio):

clip.set_output(0)
audio.set_output(1)
clip2.set_output(2)
>>>print(vs.get_outputs())
0: VideoOutputTuple(clip=<vapoursynth.VideoNode object at 0x0000021CC20F4940>, alpha=None, alt_output=0),
1: <vapoursynth.AudioNode object at 0x0000021CC20F49C0>,
2: VideoOutputTuple(clip=<vapoursynth.VideoNode object at 0x0000021CC20F4940>, alpha=None, alt_output=0)}
Or is there going to be a consensus to always interleave video and audio outputs? That's arbitrary though not safe way to handle unknown script. Some kind of info binding might be helpful.

[DJATOM]

> Or is there going to be a consensus to always interleave video and audio outputs?
There is no interleaving in nodes, they are separate objects and you have to query data on every node independently. However if you asking for automation of stuff, there's 2 possible solutions that coming onto my mind:
1) assume node 0 is video and node 1 is audio (that actually used in avfs)
2) probe every node until reach 1 video and 1 audio, discard further evaluation

[_Al_]

ok, I guess it is not important or it could be worked with because an individual works with it, it is not shared, like chopping video etc.

I'd like to correct script from above to pull a VideoNode output from script only, not AudioNodes, which I forgot about:

class NoClipError(Exception):
pass

API4 = vs.__api_version__.api_major >= 4

def vs_Source(script_path, wanted_output_index=None, **kwargs):
'''
loads vapoursynth vs.VideoNode outputs from vapoursynth script,
if wanted_output_index (int) is not passed, it gets first available vs.VideoNode if any
vs.AudioNodes are ignored
'''
vs.clear_outputs()
SourceFileLoader('script', script_path).load_module()
if API4: instance = vs.VideoOutputTuple
else: instance = vs.VideoNode
video_output_indexes = [index for index, output in vs.get_outputs().items() if isinstance(output, instance)]
if not video_output_indexes:
raise NoClipError(f'No video output found in "{Path(script_path).name}", vnode.set_output() needs to be added to the script')
if wanted_output_index is None:
index = video_output_indexes[0]
else:
if wanted_output_index not in video_output_indexes:
raise NoClipError(f'Wanted video output index: {wanted_output_index} not found in "{Path(script_path).name}" or index is not a video output')
index = wanted_output_index
return vs.get_output(index)[0] if API4 else vs.get_output(index)

clip = vs_Source("some_vapoursynth_script.vpy")

Is R65 broken somehow? At first I blamed Windows 11's new termimal for the very slow throughput (slow pipe transfer?), but nope, even using ffmepeg with -vapoursynth, the process is extremely slow, using CPU for only like 25%. Both QTGMC and MCTemporalDenoise seem to grind to a near halt. All on my new i9 12900K. This used to go blistering fast, even on my old 6700K.

Here's what I do (see below). It's almost as if multi-threading is broken for these two functions (it isn't, but appears to work exceedngly inefficient). This is 4K material, btw.

import vapoursynth as vs
import havsfunc as haf

core = vs.core
core.max_cache_size = 65535

vid = core.dgdecodenv.DGSource (r'c:\jobs\am.dgi', ct=44, cb=44, cl=0, cr=0)

vid = haf.QTGMC (vid, InputType=1, Preset="Very Slow", TR2=3, EdiQual=2, EZDenoise=0.5, NoisePreset="Slower", TFF=True, Denoiser="KNLMeansCL")
vid = haf.MCTemporalDenoise (vid, settings="very low", stabilize=True)
vid = core.neo_f3kdb.Deband (vid, preset="veryhigh", dither_algo=2)
vid = core.std.AddBorders (clip=vid, left=0, right=0, top=44, bottom=44)

vid.set_output ()


Love to learn what's going on.
And is it using only the Performance cores, or is it getting confused and either only using the Efficiency cores, or mixing up the two and throwing tasks to both types, which will bottleneck the P-cores to whatever speed the E-cores are going at?

Could someone help explain how trim and slice works in vapoursynth?

I am struggling converting a simple avisynth script where I replace a segment of a clip with some frames from a different clip and are unable to get it to work in vapoursynth.

video_a = core.dgdecodenv.DGSource(f"E:\video_a.dgi")
video_b = core.dgdecodenv.DGSource(f"E:\video_b.dgi")
video_b = video_b[12:2156] # 2156 - 12 = 2144 frames

#Neither of the following works at all in vapoursynth, I can't figure out how to reference "end of clip/last frame" in vapoursynth trim...
video = core.std.Trim(video_a,0,5298) + video_b + core.std.Trim(video_a,7444,-1)
video = core.std.Trim(video_a,0,5298) + video_b + core.std.Trim(video_a,7444,0)

#The following returns a video, but returns fewer frames than expected (7443 - 5299 = 2144 frames):
video = video_a[0:5298] + video_b + video_a[7444:-1]

Original clip has 34311 frames, but using vapoursynth slice the returned clip only has 34308.
So in python/vapoursynth either 1+1 does not equal 2 or I have forgotten how to do simple math...

[ChaosKing]

http://www.vapoursynth.com/doc/pythonreference.html#slicing-and-other-syntactic-sugar

clip = clip[5:11] <=> clip = core.std.Trim(clip, first=5, last=10)

http://www.vapoursynth.com/doc/pythonreference.html#slicing-and-other-syntactic-sugar

clip = clip[5:11] <=> clip = core.std.Trim(clip, first=5, last=10)

Wait... You are telling me that the code for slice subtracts 1 for the second argument? What exactly is the purpose for that?

I would then absolutely prefer to just use Trim rather than remembering that -1 stuff, but does anyone know how to reference the last frame in Trim like slice does with "-1" or avisynth does with trim(10,0)?

[ChaosKing]

(untested) I think it's just std.Trim(10)

[mastrboy]

(untested) I think it's just std.Trim(10)

Thanks, that worked, and I feel like an idiot for not testing it without the second argument :D

It's a lot better than the "solution" I found in my own: core.std.Trim(video,10,video.num_frames - 1)

Hi, folks.

Could somebody help me with vapoursynth?

It's been a while since I left the world of publishing but recently I took up a project that I would like to have ready for when my son is born. The fact is that I wanted to install vapoursynth and what used to work for me now doesn't.

I have checked the script and VSEdit says it is correct. The video is fine because I had to install AVS+ and it loads without any problems.

My system is: Windows 11 x64
Python installed: 3.9.9 and 3.10.1 (use VSC)
Vapoursynth: R57
Code: from vapoursynth import core
import vapoursynth as vs
core = vs.core

#video = core.ffms2.Source(source=r"C:\xxx\Movie.mkv") #,format=vs.YUV420P8)
video = core.lsmas.LWLibavSource(r"C:\xxx\Movie.mkv", format=vs.YUV420P8)

video.set_output()

Problem: Error forming pixmap from frame. Expected format CompatBGR32. Instead got 'YUV420P8'.

I have also tried VSEdit2 and when previewing the program it closes.

Nop, for VSEditor was using https://bitbucket.org/mystery_keeper/vapoursynth-editor/downloads/ and for V2 https://bitbucket.org/gundamftw/vapoursynth-editor-2/downloads/

Then, do you think that could be for VSeditor??

EDIT: I have tried the version that you post and is the same result, close of application.

[_Al_]

Wait... You are telling me that the code for slice subtracts 1 for the second argument? What exactly is the purpose for that?
As soon ,as there is a programming involved, it just works. Indexing is always from zero. So for example you need to slice an interval and you know it starts on 10th frame including and length is 5 frames, so it is:
frame=10
length = 5
clip[frame:frame+length]
If both frames were included you'd need to use clip[frame:frame+length-1]. Imagine more intervals, easily turning it into nightmare as well.

Slicing is still better, as long as you remember this rule, because, you do not need to specify position if slicing from beggining:
clip[:100] #slicing first 100 frames (you see again, you want just first 100 frames, you do this and not confusing: clip[:100-1]

or more importandly, better if slicing from a middle to the end:
clip[10:] # using 10th frame index to the end
so
clip = clip.std.Trim(first=10, last=clip.num_frames-1)
is the same as:
clip = clip[10:]

If using keyword arguments always and not just:
clip = clip.std.Trim(10, clip.num_frames-1)
is better way, because above line is not readable much. Avisynth users do that all the time, using lines like: filter(3,56, -1, 45, 1000, 0) is just a nightmare to read. :-)
Prone to make mistakes.

found https://github.com/VFR-maniac/VapourSynth-ReduceFlicker, but sadly no binaries for it.

Also available via vsrepo.
Btw you can also quickly lookup vsrepo plugins online via https://vsdb.top/vsrepogui

What can do if the DVD has video in two angles? If just use d2vwitch then get video and audio where 2 seconds of video comes from one angle and then the same action from the other angle.

Use PGCDemux or similar to extract the content you want.
There is no Vapoursynth filter (neither is there one for Avisynth) which properly parses DVD structures in details.

Why not use the good old DGIndex to create the d2v file.

I don't feel like using Windows programs even under Wine
Thanks for the answers
