You'll have to call the AviSynth script directly from a 64 bit application to load 64 bit AviSynth+ to load 64 bit plugins.

Try it first with AVSMeter64.exe – when it passes the analysis and starts processing frames, it worked.

You can also try 64-bit VirtualDub. You might want to upgrade to the latest AviSynth+ (r1825) also.

The documentation for SetFilterMTMode and Prefetch is here: http://avisynth.nl/index.php/AviSynth%2B#MT_Notes

Many thanks. I did not understand clearly the following.
Quote:
Per-frame heap allocations should be avoided, because they can act as implicit synchronization points between threads.
Can I use in getFrame method say float * var = new float[vi.width*vi.height]; and at end of this getFrame method use a delete []var; ? Does this cause the implicit synchronization? If so what should I do to have a writable buffer in getFrame section?

If you don't care about original Avisynth support, current Avisynth has IScriptEnv2.Allocate (just cast from your original IScriptEnv), which you should use with mode AVS_POOLED_ALLOC. But I don't know whether this solve the implicit synchronization, nor whether this API is stable. It is being used by internal filter though: https://github.com/AviSynth/AviSynth...ample.cpp#L755

You're going to get variety of opinions with this kind of question. I'd say use AVS 2.6 for serious work. The current AVS+ builds are really in Alpha stage and I've had problems with them, especially using complex scripts like QTGMC.

MT is alpha I agree but single threaded works completely fine in my experience.

In my tests the 32 bit r1825 (have not tested 64 bit) slows down continuously with QTGMC, no matter if single threaded or multi threaded.
There is something odd with the memory management in the newer builds, they use much less memory than r1576 or 2.6 but it seems that this is exactly what causes the slowdown. Just a hunch.

Alright thanks, I guess I will just keep using 2.6 then.

I have virtualdub 64 bit version. With version() call I get a message AVISYNTH+ 0.1 (r1576 x64)
I thought home page installer puts the latest dll.
However with SetFilterMTMode("..", 1)
I get a message no function named setFilterMTMode
The script I am using is:
l
Code:
oadplugin("C:\TransPlugins\bin_64\HistogramAdjust\x64\Release\HistogramAdjust.dll")
#----------------------------------------

SetFilterMTMode("HistogramAdjust",1)
imagesource("c:\images\source1_z.jpg",end = 500)

converttoyV12()
HistogramAdjust(limit = 70)
prefetch(6)
what is the problem?

Try a script with nothing but
Code:
Version()
and see what that gives.

The installer from avs-plus.net installs the latest stable (r1576) which does not support MT.
A link to the r1825 binaries is here.

I have just started using the latest version Avisynth+ (r1825) and seems to be working reasonable well and quicker in some situations where 64bit can be used. Looks very promising, so great work by those who have developed it to this stage.
The version I have found to work really well for almost everything is 2.6 MT but it is only 32bit.
However although I can get many scripts that work in 2.6 MT to work in plus, I can not get the following script to work at all. So I'm hoping someone can help. I use this script a lot in batch encoding and it should allow VirtualDub 64 bit to be used for that.

SetFilterMTMode("DEFAULT_MT_MODE", 2)
SetFilterMTMode("FFVideoSource", 3)
LoadVirtualDubPlugin ("C:\Virtual Dub\plugins32\Deshaker.vdf", "deshaker", preroll=0)Clip="D:\Batch Script Render\Iutput Files\Test.mts"
V1=FFVideoSource(Clip)
A1=FFAudioSource(Clip,track = -1)
AudioDub(V1, A1)#.AdvancedMultiTrim("0,-25")
ConvertToRGB32()
SCRIPT_1=Deshaker("19|1|30|4|1|0|1|0|640|480|1|2|1000|1000|1000|1000|4|1|4|2|8|30|300|4|C:\\Users\\Peter\\AppData\\Local\\Deshaker\\Deshaker.log|0|0|0|0|0|0|0|0|0|0|0|0|0|1|8|8|3|8|0|0|30|30|0|0|1|0|1|1|0|10|1000|1|90|1|1|20|5000|100|20|1|0|ff00ff")
ForceProcess(SCRIPT_1)
SCRIPT_1 = 0
SCRIPT_2=ConvertToRGB32(matrix="Rec709").Deshaker("19|2|30|4|1|0|1|0|640|480|1|2|1000|1000|1000|1000|4|1|4|2|8|30|300|4|C:\\Users\\Peter\\AppData\\Local\\Deshaker\\Deshaker.log|0|0|0|0|0|0|0|0|0|0|0|0|0|1|8|8|3|8|0|0|30|30|0|0|1|0|1|1|0|10|1000|1|90|1|1|20|5000|100|20|1|0|ff00ff")
\.ConvertToYUY2() # I can add other plugins here


return SCRIPT_2

Function ForceProcess(clip c) {
# Force process c clip
RT_DebugF("Starting Force process of clip") # EDIT: Output to DebugView (google)
GScript("""
for(i=0,c.FrameCount-1) {
RT_YankChain(c,i)
}
""")
}

This line SCRIPT_1=Deshaker .......... causes "system exception- access violation"

Any suggestion to get this to work in Avisynth + would be very much appreciated.
Thanks

Does 64-bit VirtualDub load 64-bit plugins from plugins64? Because you're pointing to the Deshaker plugin in plugins32.

Also, GScript's extensions were integrated into AviSynth+; you can just use those features natively now.

I am trying to use virtualdub 32bit to get it to work. I'm testing it on Avspmod, which only handles 32bit. I did try to load it direct into ffmpeg but that failed as well.
It is the first deshaker pass that fails to load.
I'll look at the Gscript issue later, but that shouldn't cause any of these issues.
I have also tried loading just the first pass which works in 2.6.
Thanks for your input

Deshaker plugin is not really compatible with MT avisynth. It is also internally multi-threaded. This maybe the case. Have you tried single threaded settings (if is there exist)?

Well it may not be compatible with MT but I have been using it now for a year or more with 2.6 MT.
It took many days to set it up so it would work and it renders quicker than a single thread setup.
This is an example of the script I use.
SetMemoryMax(512)
Setmtmode(5,4)
LoadVirtualDubPlugin ("C:\Virtual Dub\plugins32\Deshaker.vdf", "deshaker", preroll=0)Clip="G:\Africa\Wilds\Final Edit\Part02\199.mts"
V1=avss_26_DSS2(Clip, fps = 50)
A1=FFAudioSource(Clip,track = -1)
AudioDub(V1, A1).AdvancedMultiTrim("0,-25")
Setmtmode(2)
SCRIPT_1=ConvertToRGB32(matrix="Rec709").Deshaker("19|1|30|4|1|0|1|0|640|480|1|2|1000|1000|1000|1000|4|1|4|2|8|30|300|4|C:\\Users\\Peter\\AppData\\Local\\Deshaker\\Deshaker.log|0|0|0|0|0|0|0|0|0|0|0|0|0|1|8|8|3|8|0|0|30|30|0|0|1|0|1|1|0|10|1000|1|90|1|1|20|5000|100|20|1|0|ff00ff")
ForceProcess(SCRIPT_1)
SCRIPT_1 = 0
Setmtmode(2)
SCRIPT_2=ConvertToRGB32(matrix="Rec709").Deshaker("19|2|30|4|1|0|1|0|640|480|1|2|1000|1000|1000|1000|4|1|4|2|8|30|300|4|C:\\Users\\Peter\\AppData\\Local\\Deshaker\\Deshaker.log|0|0|0|0|0|0|0|0|0|0|0|0|0|1|8|8|3|8|0|0|30|30|0|0|1|0|1|1|0|10|1000|1|90|1|1|20|5000|100|20|1|0|ff00ff")
\.ConvertToYV12()
\.MTClipEnhance(levels=245, gamma=1.05, WB=0.20, saturation=1.20, Hue1=-2,Hue2=1)

return SCRIPT_2

Function ForceProcess(clip c) {
# Force process c clip
RT_DebugF("Starting Force process of clip") # EDIT: Output to DebugView (google)
GScript("""
for(i=0,c.FrameCount-1) {
RT_YankChain(c,i)
}
""")
}

The MTClipEnhance also has a Setmtmode within it.
I would just like to be able to use it within Avisynth + . This would save the need for changing versions and hopefully we could get a further increase in rendering speed.

I forgot to mention that yes I did try, as best as I could, a single threaded settings.

This may already be known and deemed unimportant as ffdshow is no longer being developed, but I have noticed that r1825 is not available to ffdshow rev4533 x64. Avisynth+ r1779 works as it should with ffdshow. Scripts added to ffdshow with r1825 simply have no effect.

Any idea when there will be a new release with installer? Makes deployment a bit easier.
