Never heard of it. If you want to try the multi-threaded test build, have a look at this post.

Thanks Groucho2004, I didnt understand properly this post http://forum.doom9.org/showthread.ph...85#post1651085, I thought that it was function and not a feature request.

Hi there guys! I've seen that on page 27 of this thread the users dvdan23 and TurboPascal7 where discussing the compatibility of Avisynth+ with Wine under linux half a year ago. I wanted to ask if anybody knows anything about the current status of this. I've just tried to install AviSynthPlus-r1576.exe under a fresh wine context and it does not seem to work out of the box at least.

Running a version "script" gives this error and no picture:

$ WINEDEBUG="-all" wine avs2yuv "version.avs" - | mplayer -cache 2048 -noidx -

And the reason is that the official builds of AviSynth+ are built with VS2012, and the 2012 runtime doesn't work under Wine. It's Wine's issue, which is up to them to resolve (they do try to implement this stuff on their own anyway to avoid requiring the Microsoft-provided runtimes; it's just a waiting game). Further, revisions of AviSynth+ after r1576 (not sure where the actual cut-off was, maybe in the 1630s?) can only be compiled by VS2012 or higher due to the use of C++11.

As far as r1576 is concerned, it has no such absolute restriction and can be built with VS2010. Said build would work under Wine. For those that need to do so, here is one such build:

Also, for the love of all that's right in this world, switch to mpv (PPA linked for feature completeness).

Hi

Official r1576 runs for me out of the box



(avs2yuv is launched by script in /usr/bin)

thanks for the quick and very useful reply qyot27!

Another question, is there maybe a 64bit build of Avisynth+ that has been built with VS2010 to work with wine?
I need 64bit to workaround this issue: http://forum.doom9.org/showthread.php?p=1687306
update: it doesn't need to be MT, but I need 64bit to workaround the only 28 source-files per script issue. (see link above)

Can someone please tell me how to get MT working with Avisynth+. I'm using DGDecodeNV to index my video. I'm using the Avisynth+ version of AvsPmod. Here's my script:

SetFilterMTMode("", 2)
SetFilterMTMode("DGSource", 3)
DGSource("E:\1 = Working Videos\WWE 2014\Raw from July\Raw Mar 24 2014.dgi")
AssumeTFF() 
DeGrainMedian(limitY=2, limitUV=3, mode=1, interlaced=true)
Yadif(mode=1, order=1)
Vinverse()
Lanczos4Resize(1280,720)
Prefetch(4)

AvsPmod tells me there's no function named SetFilterMTMode

In normal Avisynth MT I just did this:

setmtmode(5,9)
DGSource("E:\1 = Working Videos\WWE 2014\Raw April - Dec\Raw Mar 24 2014.dgi")
setmtmode(2)

What's the equivalent with Avisynth+?

You're using the wrong avisynth.dll. There is a post in this thread where ultim posted the MT DLL.

[VideoFanatic]

Can you give me a link to it please. I can't find it. It's not mentioned on the project's homepage or in the 1st post of this thread.

OK I downloaded the MT version from that link and copied the dlls into the SysWow64 folder. When I start AvsPmod it says [Error126] The specified module could not be found. Loading avisynth.dll failed! Make sure that AviSynth is installed. Alternatively, specify now it's directory.

Did you install the "official" r1576 AVS+ version before? Also, you can check your Avisynth install with this tool.

[VideoFanatic]

Yes. Then I copied the MT dlls into the SysWow64 folder. Used the Avisynth Info Tool and it says I have Avisynth+ 0.1 (r1689, x86) installed.

Did you try to open the script with a different program? VDub?

[VideoFanatic]

It seems to be working now. I forgot to restart my PC after installing Avisynth+ and copying the DLLs.

This was my non+ Avisynth MT script:

setmtmode(5,9)
DGSource("E:\Video.dgi")
setmtmode(2)
AssumeTFF() 
DeGrainMedian(limitY=2, limitUV=3, mode=1, interlaced=true)
Yadif(mode=1, order=1)
Vinverse()
Lanczos4Resize(1280,720)

What is the equivalent of that speed in Avisynth+ MT? I tried the following which works but I've no idea if these are the correct settings or not?:

SetFilterMTMode("", 2)
SetFilterMTMode("DGSource", 3)

DGSource("E:\1 = Working Videos\WWE 2014\Raw from July\Raw Mar 24 2014.dgi")
AssumeTFF() 
DeGrainMedian(limitY=2, limitUV=3, mode=1, interlaced=true)
Yadif(mode=1, order=1)
Vinverse()
Lanczos4Resize(1280,720)
Prefetch(9)

Can someone please tell me how MT works in Avisynth+ as I don't quite understand it. I presume the prefetch line is the number of threads you want but what do the underlined things mean?

All you have to do is read ultim's instructions in the post right below the one with the download link.
There is also a search function on this forum. One could for example search for the term "prefetch" in this thread. It's not that difficult.

[VideoFanatic]

I read them before I posted and I couldn't find anything via search. It doesn't explain what the "" part does. I'd like to know what the equivalent of the following is in Avisynth+:

setmtmode(5,9)
DGSource("E:\Video.dgi")
setmtmode(2)

Is the following script correct - everything is using mode 2?
You should use mode 2 unless mode 3 is required for the plugin to work? I want 9 threads so I entered Prefetch(9) at the end.

SetFilterMTMode("", 2)
SetFilterMTMode("DGSource", 2) 

DGSource("E:\Video.dgi")
AssumeTFF() 
DeGrainMedian(limitY=2, limitUV=3, mode=1, interlaced=true)
Yadif(mode=1, order=1)
Vinverse()
Lanczos4Resize(1280,720)
Prefetch(9)

[SamKook]

I'd suggest you read(again?) the comments from the example Ultim posted in the post below the one Groucho2004 linked, all you're asking is very well explained.

The SetFilterMTMode("", 2) line is to set the default MT mode to 2 so the "" means any filter.

There's no point in setting DGSource to 2 if you already set every filters that aren't explicitely specified to 2. But you should use 3 if you want the equivalent of 5 from avisynth and that is what Ultim suggested for most source filters.

As for the prefetch call, ultim very clearly says before the example "You enable MT by placing a single call to Prefetch(X) at the *end* of your script, where X is the number of threads to use." so yes, Prefetch(9) will give you 9 threads in MT mode(there was some things that weren't clear at one time on wether it used 9 threads for encoding or one was reserved for something else, but I don't remember exactly and I might be wrong. Either way, just try it and you'll see if it works fine).
