Enjoy! :cool:

Special thanks to the installer translation contributors.

[unskinnyboy]

Yay! Upgraded! :thanks:

[Terranigma]

Thanks Heaps. :cool:

[superuser]

thnxs, will give it a try ....

had couple of questions:

- are there are any filters which have been deprecated ?
- Is multi threading (MT plugin) support native to avisynth or will we should use MT? If not, is MT plugin available for this release candidate (sorry should ask this is in MT thread)

Cheers !

[IanB]

@superuser, Lets read the change list, Hmmmm, Additions ... Nope, Bugfixes ... Nope, Optimizations ... Nope, Changes ... Nope!

[smok3]

:thanks:

[ticapix]

Is that possible to have a tarball of the source used to build this release ?
Or to have a svn/cvs command to checkout the code corresponding to this release ?

Thanks

[Wilbert]

@IanB,

Some other changes i collected since v2.58a2 (which i think are not in the list above):
* Save variableName buffer in ConditionalReader
* Overlay: fixed and refactored RGB<->YUV conversion routines.
* TCPDeliver/DSS: Output a map in release builds.
* Usage of correct Rec.709 coefficients.
* Fix trashed GPF report, fix 0x0 at 0x0 exception reporting.
* cache: Trap NULL PVideoFrames, i.e. Don't crash, Winge!
* DSS: get convertfps=false logic right, fix Flush task interlock.

[fyo]

I really needed the range limiting on the tweak filter, so I tried upgrading to 2.58... now I cannot load my dv avi files anymore. Other codecs seem to work fine.

NOTE: I run AviSynth under Wine... Hasn't been a problem before.

I get the following error: "Could not open video stream in any supported format".

Any ideas?

[IanB]

@fyo,

What VFW DV codec do you have installed?

If you are using Cedocide what are the decode settings?

[fyo]

What VFW DV codec do you have installed?

I'm using a panasonic dv codec (psdvcodec.dll).

I'm not sure I understand why a change in AviSynth would break compatibility with the panasonic dv codec, but I just tried changing to a Main Concept dv codec I got with some old software once. It seems to work fine! (I'll continue using it for now, although I *think* there was a reason I switched to the Panasonic codec in the first place).

That at least allowed me to play around with the new and improved tweak filter... long enough to find a bug ;-)

The brightness variable doesn't conform to the hue limits set by startHue and endHue.

[Wilbert]

That's not a bug, but that's how it is designed :) :
startHue (default 0), endHue (default 360): (both from 0 to 360; given in degrees.). The hue and saturation will be adjusted for values in the range [startHue, endHue] when startHue<endHue.
Perhaps this will be added in v2.6.

Yes, that's strange. Is this also the case for older v2.58 versions (v2.58 a1/a2)?

[IanB]

@ticapix,

See Anonymous CVS Access (http://sourceforge.net/cvs/?group_id=57023)

And Browse CVS Repository (http://avisynth2.cvs.sourceforge.net/avisynth2)

You want to look in avisynth/src and avisynth/distrib


@Wilbert,

Oops, yes we have been slack in keeping the changelist up to date :o

[niiyan]

@AviSynth developers
I still work for Japanese translation of AviSynth documentaions.
But the progress is very slow.
Only 68 pages of corefilters were finished.
I would like to add Japanese translation to AviSynth 2.5.8 Final, but I don't seem to be in time for it.

So, can I add Japanese/English hybrid version of documentations to the next version after 2.5.8 (I mean 2.5.9 or 2.6.0)?
If possible, I'll try to finish translation of all corefilters pages (not all pages) and syntax.htm, etc.

* Enable Installer multi language support [Need volunteers to do translations].

Could you explain how to add other language to installer or where can I get the documentation of it?

[IanB]

@niiyan,

If you have a doco tree that you are happy with, zip it up and send it to me. PM me with some details, we can also discuss adding you to CVS or you can just keep sending us updates if CVS is to hard.
* Enable Installer multi language support [Need volunteers to do translations].

Turning on their multi language was easy. Apart from writing the language texts, I am unclear how to implement making those texts in the install script also language dependant, hence the "Need volunteers ...".

[FlimsyFeet]

Yes, that's strange. Is this also the case for older v2.58 versions (v2.58 a1/a2)?
FWIW, I remember having a problem with the Panasonic DV codec in one of the 2.5.8 alhpa versions sometime last year. Error said something like "no compatible output format". 2.5.7 was OK.

Japanese translation of AviSynth docs
http://translation.avisynth.info/index_en.html

Here is a temporal version of Japanese translation.
I also added Japanese/English hybrid version today.
But only 66 pages are in Japanese.

Note: it is now based on the documentation distributed with AviSynth 2.5.7.

We use the "Nullsoft Install System (http://nsis.sourceforge.net/)". Turning on their multi language was easy. Apart from writing the language texts, I am unclear how to implement making those texts in the install script also language dependant, hence the "Need volunteers ...".

I don't know much about NSIS, but I found the following pages:


Creating language files and integrating with MUI - NSIS (http://nsis.sourceforge.net/Creating_language_files_and_integrating_with_MUI)
Scripting Reference (http://nsis.sourceforge.net/Docs/Chapter4.html#4.10) (Example (http://nsis.sourceforge.net/Examples/languages.nsi))


I hope it will help you.

[sidewinder711]

Thanks a lot to IanB and all others, who are involved in the development of this great tool! I'm looking forward to check out/test the new features. :thanks: :)

[Ajax_Undone]

WOW Works great just downloaded it... AVS Editor is missing its C# Project side of its code in SVN JSYK...

Tried Compiling it earlyer today... :-)

[IanB]

@niiyan,

Thanks for the NSIS research, "LangString" was the piece of the puzzle I had been missing. :D

I'll open a new thread to collect translations of the Installer texts now I know how to use them.

I will import your avisynth_docs_ja_temporal.zip into the docs tree.

I can diff new versions with avisynth_docs_ja_20080529.zip to apply updates as you do them.

Just PM Wilbert or me when you have updates or with any other issues.

[niiyan]

@IanB

I will import your avisynth_docs_ja_temporal.zip into the docs tree.

Is that mean Japanese documentation will be included in AviSynth 2.5.8 Final? Or in the later version than 2.5.8 (2.5.9 or 2.6.0)?

[tacman1123]

NOTE: I run AviSynth under Wine... Hasn't been a problem before.



I don't see Avisynth in the Wine AppDB, but I do see that an old version of MediaEncoder is (which since 2006 has supported Avisynth).

Were you able to get it to run only the native Wine dll's (that is, not needing a licensed copy of Windows)? If so, now that Wine has been officially released using it may be an acceptable solution for people looking for a way to run Avisynth under Linux. I'm not holding my breath for Avisynth 3 and the Linux port, but if it runs under Wine that's certainly worth knowing.

Currently searching for 'linux' on the avisynth wiki yields very little, one tiny mention of avs2yuv on http://avisynth.org/mediawiki/FAQ_frameserving. Would you consider modifying that page with a question/answer in the format

Q: Does Avisynth run under linux?

A: Not as a native application, but to run Avisynth with Wine, do the following:

Thx,

Tac

[tacman1123]

Added font aspect, rotation and alpha to text routines.

Does this mean to the C routines, or to Avisynth calls such as Subtitle()?

I see that 2.5.8 now allows Subtitle() to have accented characters (UTF8), that's great, so now

ColorBars.Subtitle("¿En qué año nació?")

works as expected -- thanks!

Tac

[IanB]

@tacman1123,

Avisynth is not an application it is a library, as such you need a host application to run it under.

There should be no real issues under wine per se, it has no UI component and just needs an msvcrt.dll plus minimal system support from kernell.dll, etc.

However AVISource() needs the full VFW infrastructure plus DirectShowSource need the full DirectShow environment as well and these can be problematic licensing wise i.e. you need a donor windows for these components. Other functions like SubTitle need the appropriate font files.

Any contributions to documentation about Wine issues will be gratefully accepted, PM Wilbert or Myself.



And about Subtitle(), sorry no it is still uses ANSI encoding. Looks like you just managed to get your codepage settings correct.

[kandrey89]

delete plz.

Currently, Avisynth works quite well under Wine. While you might run into problems with avisource() or directshowsource(), ffmpegsource() works just fine and supports most common stuff. Output to native Unix applications works just fine with avs2yuv. I've tested with mencoder and it works fine provided that you tell it to cache a bit.

[Revgen]

I don't know if this is the appropriate thread, but here it goes.

Why can't avi's with no sound and avi's with sound be combined with avisource?

I basically had to go into Nero WaveEditor create a null wav file and add it to my noaudio avi using AudioDub to trick avisynth into combining the 2 avi's. Can there be a audio=null option to insert a null audio track automatically?

[IanB]

The restriction is actually in Splice. AviSource() automatically UnAlignedSlice()'s all the files provided. The restriction being all the files must be compatible, i.e. same Height, Width, Colour space and Audio format. If the files are incompatible then the script author must provide the knowledge to resolve the incompatibility and join the disparate clips together.

In your case you could have used the Audio=False option for the videos streams and sourced the Audio track separately and then AudioDub()'d it laterAviSource("FileA.avi", "FileB.avi", Audio=False)
AudioDub(WavSource("FileA.avi"))else you could AviSource each clip separately, add a blank audio track the clip without audio and then splice them.A=AviSource("FileA.avi")
B=AviSource("FileB.avi") # No audio stream
A ++ AudioDub(B, BlankClip(A))

I don't use blankclip much. I assumed it was a command used for video instead of audio. So basically Blankclip(A) gives the noaudio AVI a null audio stream with properties (khz, samplerate, etc) similar to the AVI with sound? If so, then thanks. This will be usefull the next time I try use it.

[Wilbert]

So basically Blankclip(A) gives the noaudio AVI a null audio stream with properties (khz, samplerate, etc) similar to the AVI with sound? If so, then thanks.
Yes, indeed. I will add this example to the documentation.

[IanB]

More correctly the "AudioDub(B, BlankClip(A))" does.

[Revgen]

^Okay, well, in that case whenever somebody tries to combine a video with no audio and a video with audio, instead of an error message saying "AVIsource can't combine these files", it should say "One of your clips contains no audio. Use Blankclip to add a blank audio stream" or something of that sort.

[IanB]

@Revgen,

:confused: What version are you running? "AVIsource can't combine these files" is not a current message. The validation code for splice is :- if (vi.HasVideo() ^ vi2.HasVideo())
env->ThrowError("Splice: one clip has video and the other doesn't (not allowed)");
if (vi.HasAudio() ^ vi2.HasAudio())
env->ThrowError("Splice: one clip has audio and the other doesn't (not allowed)");
...
if (vi.width != vi2.width || vi.height != vi2.height)
env->ThrowError("Splice: Frame sizes don't match");

if (!vi.IsSameColorspace(vi2))
env->ThrowError("Splice: Video formats don't match");
...
if (fabs(fps_v1-fps_v2) > 0.000001)
env->ThrowError("Splice: Video framerate doesn't match");
...
if (vi.AudioChannels() != vi2.AudioChannels())
env->ThrowError("Splice: The number of audio channels doesn't match");

if (vi.SamplesPerSecond() != vi2.SamplesPerSecond())
env->ThrowError("Splice: The audio of the two clips have different samplerates! Use SSRC()/ResampleAudio()");

[weaker]

In the changelist I can't find information regarding greyscale/Y8 support. The early alpha version had some support for it, does the RC2 still have it or was it delayed to another milestone?

[RedDwarf1]

What is avsrecursion.dll and how does it relate to AVISynth? After installing this release I am getting an error in multiple applications saying avsrecursion.dll cannot be found. Uninstalling it does not fix it either.

[Wilbert]

In the changelist I can't find information regarding greyscale/Y8 support. The early alpha version had some support for it
No it didn't. v2.6 will have Y8 support.

avsrecursion (http://home.arcor.de/kassandro/AvsRecursion/AvsRecursion.htm) is not an AviSynth plugin. It should be in your system folder.

[weaker]

Sorry, I was thinking of 2.6.0 pre-alpha. Mixed things up. Thanks Wilbert for clarification.

[RedDwarf1]

No it didn't. v2.6 will have Y8 support.


avsrecursion (http://home.arcor.de/kassandro/AvsRecursion/AvsRecursion.htm) is not an AviSynth plugin. It should be in your system folder.

Thanks Wilbert for the link. After I put that into my system directory, all the encoding appz now run. But it's very strange why it should be needed as I am not using any of the plugins that require that dll. Maybe the windows CD that I prepared got a bit messed up when I prepared it. That is the only thing it can be as I the same thing happened with 2.5.7 after I restored a backed up DVD of windows.

[foxyshadis]

You may have downloaded a new version of AvsTimer, RemoveGrain, ReduceFlicker, or RemoveDirt, all of which require avsrecursion now. If they're in your autoload plugins, then they'll always load with every script, thus erroring every one.

[stax76]

I wonder how near the final is? Need to know planning StaxRip release schedule.

[IanB]

A few weeks, we are just polishing the installer with some foreign language support and catching up the doco language translations. So unless someone reports a show stopper, RC3 (same core as RC2 +1 fix and latest Docs) will ultimately become the Released version.

[Didée]

Issues/suggestions from the hop of my tead:

* Bob():
- chroma displacement with YV12 input (!!)
- resets field order always to BFF, instead of keeping the original parity

We've got used to those behaviours, but frankly, it's just embarrassing.


* Blur()/Sharpen():
what about some sort of "chroma" or even better "plane" parameter. Sure, you can always MergeChroma/Luma() afterwards, but it's inefficient. If one wants to sharpen only luma, you have to: first actually let the filter process the chroma planes, then copy the respective planes back from one clip to another. That's more work than to do just *nothing* to those planes. And with e.g. HD input and/or very complex scripts, every little bit counts.
Since RGB does not have "chroma" as such, the most convenient way (probably) would be to have Y,U,V parameters (with R,G,B aliases) like in MaskTools.

[Wilbert]

* Another issue:

http://sourceforge.net/tracker/index.php?func=detail&aid=1944770&group_id=57023&atid=482673

It's strange that it doesn't crash in VDub directly when scrolling to the second frame.

[IanB]

@Didée,

I will change the behaviour of Bob() for 2.6. The chroma displacement is configurable in the 2.6 resizer core, so this needs to be visited anyway.

I have on my 2.6 to-do list, "make planar planes as Y8 with zero cost", they currently get bitblt'd, soMergeLuma(ConvertToY8().Sharpen(0.2))will do what you ask when implemented.

@Wilbert,

That file http://www.quyo.de/~mfie/foo/avisynth_crash.avi does not crash for me with any version of avisynth. Does it crash for you? What VFW Huffyuv decoder are you using?

[Wilbert]

That file http://www.quyo.de/~mfie/foo/avisynth_crash.avi does not crash for me with any version of avisynth. Does it crash for you? What VFW Huffyuv decoder are you using?
I tried both the original version and huffyuv_ccesp-patch_025 (see Doom9's download section). Which one are you using?

[IanB]

@Wilbert,

The huffyuv_ccesp-patch_025 from Doom9's download section.

So it does crash for you? or not?
