Latest update to zimg fixed this for me, no more segfaults here.

R39 test4

I miscompiled test3 so that's why it didn't work. That's what happens when you have to reinstall everything on a new computer...

Yes the problem is fixed now, thanks

Hello. You can call me stupid, but I broke my head. I'm pretty good in Avisynth, but in Vapoursynth is a beginner. I have Xubuntu 16.04 x86, Vapoursynth from PPA. I need to connect avisynth TIVTC.dll plugin, because of 2-pass mode=2 and mode=4 (I have a complex video), which is not in VIVTC. And I can not.

import vapoursynth as vs
core = vs.get_core()
core.avs.LoadPlugin(TIVTC.dll)
video = core.ffms2.Source(source=input.mkv)
video = core.avs.TDecimate()
video.set_output()

vspipe --y4m script.vpy - | ffmpeg -i pipe: output.mkv

writes errors like that:
No attribute with the name avs exists. Did you mistype a plugin namespace
Help me, please.

Try add "-" after output:

vspipe --y4m script.vpy - | ffmpeg -i pipe: output.mkv -

You can't load avisynth plugins in linux. If that's what you're trying to do.

Maybe not yet ...

Not by me. Proper ports are better anyway. You'd still need x64 versions of everything which not all things have.

I have a dream that one day an avisynth user will suggest doing the right thing and not just another shitty compatibility hack.

[LigH]

Of course. A cross-platform portable loadable library format ... sigh ... Mono?!

It's called C. With a system compiler. Works everywhere.

[LigH]

May there be no system dependent function calls. Or references to external libraries (like FFT3D). Do it yourself ... everything ... from scratch. Or from other OpenSource projects. Rely on the community! Closed Source is so ... last millennium.

Thanks. This should be specified here so as not to mislead people.

What the point of Vapoursynth then? Another fork? Windows has a working learning Avisynth. Linux does not have avs plug-ins, so Avisynth under Wine is the best solution then.

Native binaries are native only. You should definitely know this since you've heard about wine.

VapourSynth also isn't a fork. The point is code quality, portability and proper multithreading support. And more flexible scripting too.

And no, not caving in to your documentation demands. It shall remain unchanged.

vaporsynth got the ability (std.Expr) to evaluate RPN expressions on 32 bits floating point precision video clips and take (practically) arbitrary amount of clips as the input, while avisynth got the naïve mt_lut(xyz) that takes up to 3 clips and only works with 8 bits low precision clips
that's enough for me to sentence avisynth to death

Unlike Avisynth, VS isn't completely awful.

[poisondeathray]

But avisynth has things that vapoursynth can't do right now. Like audio.

So not completely aweful

Can someone help why it is not possible to feed a HDR10 encoded content to x265 to reencode using DGDecNV (latest with HDR10 support) and Vapoursynth?

Error message as follows:

x265 [error]: unable to open input file

Author of DGDecNV suggested asking the Vapoursynth guys about it. What information should be provided for support?

I am not a programmer, not using Vapoursynth directly but perhaps can provide all the info required to find the reason for the problem.

Please help.

Your VS script would be a start.
