update - ok, I read they are not needed anymore but I would like to know where the 64 bit plugins reside?

Updating on my issue with loading multiple instances of a virtualdub filters. I did more testings on a few more vd filters, the problem should be coming from either avisynth or virtualdub. (I highly believe that it's avisynth)
Loading multiple instance of any vd filter in an avs script will result in an "out-of-bound memory access" crash on program close, which is the same behavior I had in vapoursynth earlier.

This will crash in avisynth:

LoadVirtualDubPlugin("Autolevels.vdf", "Autolevels", 0)

src = AVISource("sample.avi").ConvertToRGB32()
a = src.Autolevels(40, 46, 50, 0, 0, 0, 0, 0)
b = src.Autolevels(40, 80, 50, 0, 0, 0, 0, 0)

a+b

This will work:

LoadVirtualDubPlugin("Autolevels.vdf", "Autolevels", 0)
LoadVirtualDubPlugin("Autolevels_copy.vdf", "Autolevels_copy", 0)

src = AVISource("sample.avi").ConvertToRGB32()
a = src.Autolevels(40, 46, 50, 0, 0, 0, 0, 0)
b = src.Autolevels_copy(40, 80, 50, 0, 0, 0, 0, 0)

a+b

Yes, already reported, something like a double free at exit, don't spend any more time investigating on the vs side.

Ok hope this get fix soon, getting it to work fills in the last missing piece of my project.

Is there a function that can replace a range of frames with another range of frame of the same clip?

I want to replace frame 200-250 with frame 0-150. It's not remapping, the length of the resulting clip should be different to the original. I looked into remapframes but it doesn't have it.

[AzraelNewtype]

Sure.

I know that we can write it using those native functions. I'm just asking to see if we have something written already.

I have another question about slicing, is there a short form to get a clip of N frame to the end of the clip? "clip[50, -1]" only gets frame 50 to the second to the last frame, is there a flag that represent the last frame of the clip?

[AzraelNewtype]

clip[50:]

Of course [:-1] is only giving the second to last. That's what negative slice indexes do.

As for wrapping three trims and a splice to do arbitrary replacement of unrelated clips, that kind of really small helper function isn't the sort of thing people share libraries of. A naive implementation is probably about five lines. It's barely even syntactic sugar if you have to define the trim points of the input and replacement separately.

Reporting a memory leak on ModifyFrame as I found it here earlier.

Memory will not flush after I closed preview in vs editor. Using the sample script from the document will cause the leak:

def set_frame_number(n, f):
   fout = f.copy()
   fout.props['FrameNumber'] = n
   return fout

clip = core.std.ModifyFrame(clip=clip, clips=clip, selector=set_frame_number)

I've found 3 memory leaks so far in various places. Expect the next version to improve on things a lot. Note that all leaks more or less only happened when objects were destroyed so it'd never be discovered when using vspipe or simply encoding things.

R41-test1

Some of the fixes required fairly big changes in the cython code so test as many scripts as possible. This binary should be considered alpha quality.

r41:
updated to zimg v2.7
removed dependency on the now deprecated codecvt header
fixed memory leak where modifyframe wouldn't release the function reference when done
fixed a rare memory leak that could happen if the core was freed before the last frame 
fixed a memory leak that would happen if a python videoframe object was instantiated
improved imwri's input and output format guessing, now integer and float image formats will most likely be returned in native precision
imwri now requires hdri support since it's now enabled by default
stackvertical now properly rejects compat formats instead of producing unexpected output
the default initial cache size now also depends on the number of threads used
fixed negative frame request error listing the parent node name instead of the correct name
fixed expr clamping of 9-15 bit output, previously it would clamp to 16bit
fixed corrupted output in expr when mixing int and float for input and output (pinterf)

Imwri builds will be provided separately at a later time when more testing has been done.

Thank you, the leak is now gone, memory usage drops back to 30MB after preview close.

I can't get it working, I tried various formatings but all failed.

from functools import partial

img_dir = r"F:\temp_img_w\{}.png"

def set_frame_number(n, f):
	fout = f.copy()
	fout.props.FrameNumber = n
	return fout

clip = core.std.ModifyFrame(clip=clip, clips=clip, selector=set_frame_number)

def writeimgfn(n, f, clip, path):
	num = f.props.FrameNumber
	rgb_clip = core.resize.Bicubic(clip, matrix_in_s="709", format=vs.RGB24)
	return core.imwrif.Write(rgb_clip, imgformat="PNG", filename=path.format(n))

clip = core.std.FrameEval(clip, partial(writeimgfn, clip=clip, path=img_dir), prop_src=clip)

clip.set_output()

It returns error "Write: Filename string doesn't contain a number".

Unless you have a more complex use case than this example you should simply be using vspipe and ffmpeg to write images. How does your script fail anyway?

I'm working on a project to color match dragon ball z, for better color matching accuracy, I need to build a big montage for every scene and stored them as a clip, like 1 frame = 1 montage, each frame resolution varies. After that I need to output all the images to be use for the color matching program.

By tagging and saving a frame number onto each output image instead of the sequence counter will help to back track if something went wrong. For example, if one of the images gives poor matching result, I would know exactly where to look for that scene.

I'm trying to use vapoursynth's avs.LoadPlugin(string path) to load some avisynth filters, however whenever I try to load almost any filter I will get the error:

Failed to evaluate the script:
Python exception: Avisynth Loader: failed to load module

Traceback (most recent call last):

Any idea what could be causing this? I'm running Vapoursynth r40 and Avisynth 2.6 x86.

Thanks!

Did you escape the path properly?

[kriNon]

Ah sorry, forgot to post my script:

import vapoursynth as vs
core = vs.get_core()

core.avs.LoadPlugin(r"C:\Program Files (x86)\AviSynth\plugins\deen.dll")

Yeah, I did

[LigH]

I believe VapourSynth may not be able to load AviSynth plugins with the ancient v2.0 or v2.5 interfaces, but require v2.6... so: Do you have a few examples which plugins load and which don't?

[kriNon]

I've only tested a few, I remember that TIVTC v1.0.5 didn't work, but v1.0.9 worked. Neither Deen or eDeen have worked for me, however I've seen that in https://github.com/vapoursynth/vapou...nth_compat.cpp there are the lines:
PREFETCHR1(deen)
PREFETCHR0(eDeen)
so I assume that there is compatibility?

Also someone used Deen in their vapoursynth script here:
https://gist.github.com/4re/bba3f65469acfe0ec08a

EDIT:
I tested a few avisynth plugins at random to see which ones worked, and can confirm that I got the same error message when trying to load Average, BlendWeight, ColorBalance, FFT3DFilter, and Vinverse.

I have recently reinstalled both Avisynth and Vapoursynth and am having the same error.
