I've been searching for this as well; it shouldn't be that bad to do it by hand though.

Ask and ye shall receive:
FFT3DFilter
ReduceFlicker
TNLMeans

I only tested the x64 versions of each...

A bunch of to you...

There is a bug in using Expr:

import vapoursynth as vs
import sys


core = vs.get_core()

core.max_cache_size=1000

a = "anysource.mkv"
src8 = core.lsmas.LWLibavSource(a,threads=1)

res = core.std.Expr(src8, ["128 x - 1 < 128 128 ?",""])
res.set_output()


the vapoursynth.dll shall crash.
However, once can just avoid it by using "x - 128 -1 > 128 128 ?"

Waiting for replies, thanks.

Fixed now. It affects expressions that use the ternary operator, where its first operand is an expression that begins with a constant.

Thanks dude. So efficient.

Just a thought I had recently but is it actually possible to use vpy within c++ without having to call python scripts snd whatnot. I'm talking about calling vpy functions and plugins from within the cpp project.

For example I have a cpp project that generates an image and I want to resize that image without fully making my own resize function, could I then call vpy's internal resize function to do the work or even call the nnedi3 plugin?

Yes, it's possible. You can build a filter graph in C/C++. Here is an example that happens to invoke the internal resizer: https://github.com/vapoursynth/vapou...svapour.c#L504 . For your particular case, you'll also need to implement a VapourSynth source filter in your application.

If it's only the internal resizer you want, you should use zimg directly. It has C and C++ APIs.

Has anybody been able to cross-compile VapourSynth using Linux?

I'm trying to use MXE (M Cross Environment; mingw32-w64 toolchain builder) and it compiles mpv without any problems, but VapourSynth requires Python 3.4 and I'm stumped on how to properly compile the VapourSynth DLL...

It has been done. There are some hoops to jump through.

Note that cross-compiling a 32 bit libvapoursynth produces a broken DLL. I didn't investigate, but I think it has to do with function decorations somehow.

You could try to cross-compile Python, but I found it easier to use the official win64 installer in Wine (even if it took a few hours to find the magic switch that made msiexec work).

So, assuming you will use the official Python installer, the configure command will look something like this:

./configure --host=x86_64-w64-mingw32 --disable-python-module --disable-plugins PYTHON3_CFLAGS='/path/to/Python3.h' PYTHON3_LIBS='-L/path/to/libpython3.dll -lpython3'

--disable-python-module because Python modules have to be compiled with the same compiler as libpython, so you'll have to use the Python module provided in the official VapourSynth installer.

--disable-plugins because I assume you won't need those.

PYTHON3_CFLAGS needs to be passed to please the configure script. Point it to the Python installation's "include" folder.

PYTHON3_LIBS is also needed to please the configure script. Point it to the Python installation's "DLLs" folder. Inside, you will need to rename Python3.dll to libpython3.dll because otherwise libtool refuses to acknowledge its existence. This means you'll also need to rename Python3.dll on the Windows machine where this thing will run.

Most unfortunately, you will receive a libvapoursynth-script-0.dll instead of vsscript.dll.

Don't use GCC 5.3.0 for this because its libstdc++ has a bug that makes wstring_convert unusable. This is a problem for VapourSynth. GCC 5.1.0 is okay.

If it's for mpv, I think you'll find it much easier to convince mpv's build system to use the vsscript.dll provided in the official VapourSynth installer, or the portable archive.

[sofakng]

Thanks a lot for the help. I ended up using dlltool to generate the lib files (for vapoursynth.dll and vsscript.dll) and I was able to get mpv compiled with vapoursynth supported. I still need to try it on my actual win32 machine so who knows if it will work but at least it compiled

[sofakng]

Sorry, but one more question.

Is there an installer for the 64-bit version of VapourSynth? It looks like VapourSynth-R32.exe only installs the 32-bit version.

Hi, I am getting "VSPipe.exe has stopped working" when trying to process Quicktime Prores 4444 files. Here is the script:

import vapoursynth as vs
core = vs.get_core(threads=4)
ret = core.lsmas.LibavSMASHSource(source=r"Prores_4444_HD_Test.mov")
ret = core.fmtc.resample (clip=ret, w=480, h=384, css="444", kernel="spline36")
ret = core.fmtc.matrix (clip=ret, mats="709", matd="601")
ret = core.fmtc.resample (clip=ret, css="420")
ret = core.fmtc.bitdepth (clip=ret, bits=10)
retFinal = ret
retFinal.set_output()

I am on the latest version of Vapoursynth (R32) and the latest version of LSMASHSource (r877). Here is the crash report:

Am I doing something wrong, or is this a bug?

Kind regards.

I've downloaded a YUV444P10 sample and got an VS error telling YUV444P10 is not supported by VFW module, could it be supported? I get this error not only with StaxRip and VirtualDub but also with MPC-BE which I thought does not use VFW.

The problem is that there is no fourcc to represent it that I know of. The closest are ms p010 or whatever it was called and v210 which are both 10bit but subsampled. Find me a fourcc that's actually supported in applications and I'll consider adding it.

[stax76]

Who might help here, maybe the author of MediaInfo or VirtualDub?

No, must be uncompressed formats obviously.

YUV 444 10bit packed is known as "Y410", but it's not supported in ffmpeg as a pixel format .


https://msdn.microsoft.com/en-us/lib...px#_444formats
https://en.wikipedia.org/wiki/FFmpeg#Pixel_formats

It's also known as "v410" (analgous to "v210" for 10bit422) but 10bit444
