Vapoursynth

[Kupildivan]

Are they have to be the ported ones? Or native avisynth plugins will work too?

[Are_]

Vapoursynth's QTGMC works with vapoursynth filters only, except for the denoising. It uses avisynth's fft3dGPU and FFT3DFilter if they are selected, else it uses native dfttest.

[MonoS]

As Are_ said all plugin are native, for avoiding to use avs plugin remember to set denoising to at least Slow or set manually the denoiser to dfttest [also you can use 16bit precision if you want ]

It's clear, but interestingly how ffms2 decoding interlaced sources now. Is correctly (for smoothed 2x fps with phases saving)? I don't know about 2.20, may be interlaced sources now is fully supported... Else have need to use directshowsource2 that impossible in vapoursynth.
Thanks to all vapoursynth's (and plugins) devs for the crossplatform and modern frameserver!

Have you tried with lsmash??

I confirm that lsmash works fine. ffms2 with "threads=1" should works too.

No, i will try later.
ffms2 works even without param 'threads=1'.
Also, vs works and all needed plugins loaded.

libaddgrain.so libdeblock.so libffms2.so libgenericfilters.so libmvtools.so libscenechange.so libtemporalsoften2.so libyadifmod.so
libdctfilter.so libeedi2.so libfmtconv.so liblsmash.so libnnedi3.so libtdeintmod.so libtemporalsoften.so

import vapoursynth as vs
import havsfunc as haf
core = vs.get_core()
v = core.ffms2.Source(source='2_1080i.mkv', fpsnum=25, fpsden=1)
v = haf.QTGMC(v, Preset='Slow', TFF=True)
v = core.fmtc.resample(v, w=1280, h=720, kernel="spline64")
v.set_output()

vspipe --y4m script.vpy - | x264 - --demuxer y4m --crf 20 --profile high --level 4.1 --preset slow --output encode.mkv

Script don't show errors, but x264 breaks:
x264 [error]: could not open input file `-'
Streaming into pipe also don't works.
If script runned without qtgmc then x264 encodes stream.

import vapoursynth as vs
import havsfunc as haf
core = vs.get_core()
v = core.ffms2.Source(source='2_1080i.mkv', fpsnum=25, fpsden=1)
v = core.nnedi3.nnedi3(v, field=3)
v = core.fmtc.resample(v, w=1280, h=720, kernel="spline64")
v.set_output()

vspipe --y4m script.vpy - | x264 - --demuxer y4m --crf 20 --profile high --level 4.1 --preset slow --output encode.mkv

It works.
x264 compiled with options: --enable-static, --enable-shared

[jackoneill]

vspipe should output some error message, but if you don't see one, run this instead, to make sure x264's output isn't overwriting it:

vspipe script.py /dev/null --progress

This breaks segfault.

Maybe are you using an outdated version of some filter? This does not crash for me.

All libs have been compiled from sources (from here or git). May be required libs were missed? What plugins and which versions are you using?

[jackoneill]

A missing plugin would result in a different error message (usually).

Did you compile GenericFilters from here? https://github.com/chikuzen/GenericFilters
The original author disappeared and left behind a number of bugs which have been fixed here: https://github.com/myrsloik/GenericFilters.

Thanks! Myrsloik's version of GenericFilters works fine.

Will VS be supporting audio proccessing? (it's may be helpful for ts hdtv videos with errors).

I encountered a problem with plugin loading on my friend's computer.

Windows7 SP1 64bit
Python 3.4.3 32bit&64bit
VapourSynth R26 32bit&64bit

With print(core.list_functions()) in Python command line(both 32bit and 64bit were tested), only the core functions were displayed. None of the plugins in VapousSynth\coreXX\plugins and VapousSynth\pluginsXX were auto loaded.
Trying loading those plugins manually, it didn't work either. Running the script with vsedit64 or vspipe64, it always returns the error 'Failed to load XXX.dll'.
I've confirmed that all the required MSVC runtime dlls were installed.

The error message is something like this one:

[kolak]

I have the same issue.
Myrsloik is aware.

I see that we use same/latest Python- can this be the reason?

[RTW47]

updated Python 3.4.1 > 3.4.2 > 3.4.3, but don;t seem to have any problems with it (so far);

I'll try to make the error message when loading plugins more informative. Unfortunately the windows api will never reveal to you the name of a missing file (if any).

For Avisynth an excellent tool for this purpose (and a lot more) was created by Groucho2004 : it's called AVS Infotool (see http://forum.doom9.org/showthread.php?t=170647 )

The "plugin" function from this tool shows all the auto-loaded plugins with their dependencies : see images.

Maybe something similar can be created for VS ?
You could also use "Dependency Walker" to check the dependences from this .DLL plugin.
