AviSynth 2.6.0 PRE-Alpha - Release!

[Wilbert]

AviSynth 2.6.0 PRE-Alpha [August 11th] 2006 - Release!

Here's some little toy to play with while it's still holidays (at least for some of us). It's a pre-alpha release, so use it at your own risk and DON'T use it for regular encodings.

The changelist with respect to v2.56 (note that the v2.57 fixes are not merged yet):

Additions:

* Added MaskHS.
* Made VC8 project files.
* Minor tweaks for VC8 compile. All changes should be compaible with VC6 - there are two Soundtouch libraries for the same reason.
* Made VC8 projects for DirectshowSource and TCPDeliver.
* New "Tweak" functionality (options from TweakColor from Trevlac): It enables you to adjust the hue and/or saturation in a specific hue range [startHue,endHue] and/or in a specific saturation range [maxSat,minSat]. Some interpolation to the prescribed saturation range is added to prevent color banding. The interpolation can be set with "p" (p=0 won't interpolate, p=5 is maximal).
* Add Y8 for DevIL, planarize EBMP.
* Planar support for many filters.
* Added time indicator on audio length and video (current frame & total).
* Added specific error reporting when requesting subsampling on Y8.
* Added MultiThreading support, including ScriptEnvironment::SetMTMode and ScriptEnvironment::GetMTMode.
* Added UtoY8 and VtoY8.
* Added more info to Info().

Bugfixes:

* TCPDeliver: Using TCP_NODELAY, this will kill latency on client request packets, and server replies.
* Increment sequencecount in MakeWritable to avoid crash when calling GetFrame between MakeWritable() and GetWritePtr().

Optimizations:

* Added dynamic compiled MMX/iSSE for RGB<->YV24 conversions. Speed is approx 200% of C-code.

Changes:

* Threading in TCPDeliver does not use AFX anymore.
* Updated Soundtouch to 1.31.
* Put dynamic matrix conversion into separate file.
* Moved chroma subsampling to image_type section.
* Added a synchronization class IClipLocalStorage and smartpointer PClipLocalStorage to handle synchronisation between class instances when using MTMode 2 and 4.
* Split up merge and plane Swappers.
* Split up Plane transfers into separate classes.
* Added automatic destination colorspace detection on planar YtoUV.
* Took out greyscale and RGB32<->RGB24 from convert.cpp and placed them in separate files.
* All code assuming UVwidth = Ywidth/2 and similar should be gone.

some references:
* 2.6 proposal: http://forum.doom9.org/showthread.php?t=98585
* AviSynth 2.6 move to VC2005 Express: http://forum.doom9.org/showthread.php?t=112138

Note that if you are going to play with one of the new color formats don't forget that they (at least most of them) are not supported by the standard codecs. So you always need to end your script with ConvertToRGB/ConvertToYV12/ConvertToYUY2.

[Kostarum Rex Persia]

Very good, keep going.

[foxyshadis]

It runs! Without crashing horribly at every frame! I'd say it's ready for release. ;)

Do you know if there's any way to run 2.6 and 2.5 side-by-side? I suppose it wouldn't be easy without adding support for some kind of "# Avisynth 2.5" statement at top.

Is the ABI ready for prime time, or still in flux?

The new colorspace modes are going to be awesome.

[squid_80]

You can do the trick of copying whichever avisynth.dll you want to use into the same directory as the host program.

[Wilbert]

Is the ABI ready for prime time
Nope. The most important thing which should be done before an alpha release is the baked code removal:

http://forum.doom9.org/showthread.php?t=101730

[Manao]

Nope. The most important thing which should be done before an alpha release is the baked code removalIt would also be nice if :
- when compiling with -W4 with VC8, there weren't ~10 warnings generated by avisynth.h ( that's also true for avs2.5 ). Removing baked in code should take care of most of those anyway.
- colorspaces I400, I422 and I444 were added ( since there are both I420 and YV12 )

Meantime, I hope to release a masktools for 2.6 this afternoon, which would support Y8, YV12, YV16 and YV24.

[foxyshadis]

I4xx are just the YUV variants of YVxx YVU formats, right?

[Manao]

Yes, they are. But U and V are ordered differently, and though it doesn't matter in avisynth, it matters for interfacing it with Vfw.

Anyway, here is a version of the masktools for avisynth 2.6. There's no source code yet ( but there are hardly no differences ), no version numbering ( blame vc8 express ), but both should come back soon enough.

I'm getting that adminstrator install error that 2.5.7 was giving people.

[IanB]

@Blackwoods,

Well DUH!(note that the v2.57 fixes are not merged yet):Unprotect your color.avsi file (and DirectShowSource.dll and TCPDeliver.dll)

@All,

Please don't clutter this thread with problems known to be fixed for 2.5.7 until a fix merged rev is at least commited to CVS.

[Backwoods]

I was installing to a new folder. Apparently that was dumb on my part...DUH

[foxyshadis]

I'm curious, because I'm starting to use the 2.6 header for all plugins. (The current version works fine with 2.5 with a few tweaks.) Is there going to be a convenience method like vi.PlaneCount() to take Y8 and whatever else pops up into account?

It's not a huge deal, just keeps from repeating the same code - int PlaneCount = vi.IsY8() ? 1 : 3; - in everything. Plus it's obviously far more flexible externally, if it's ever going to change.

[IanB]

That is not a bad idea.

Be prepared for many iteration of Avisynth.h as we strive to get it right.

[Ignus2]

What happened to avisynth 2.6? Is it being developed? Is there going to be a release of 2.6? 2.6 has some cool features, like Y8 video among others, and I really would like to see a stable release of it.

So, how is development going on with it?

Yes, it's still being developed. The changelog can be found at:

But only IanB knows when the first alpha will be out.

[Wilbert]

<removed post; there are too many bugs in it ...>

[buzzqw]

wow! thanks!

would be ever possible to GetMTMode/SetMTMode (for MT plugin).
get "automagically" MT mode whenever possible ? (without using MT plugin)

thanks to all Developers of this fantastic software!

BHH

[Adub]

Super sweeeeeeeeet! Thanks a buncho!

[IanB]

Don't get to excited Wilbert has jumped the gun, this version will have some pretty insideous bugs (I am halfway thru some radical changes).

[Adub]

Ah damn, I did get too excited. I will just have to wait until you say it's safe then.

[Ignus2]

What's the situation on this? How is 2.6 going?

[IanB]

Slowly, bit by bit.

[hajj_3]

will it be multithreaded and 64bit native or compatible? sse3 and sse4?

[sh0dan]

@hajj: "mt" is natively supported. No official 64 bit. Colorspace and vertical resizer have been ssse3 optimized.

[ilhyfe]

Is it possible to get the source via CVS? I didn't find it on the project page.

[Fizick]

it s in same place, but in "avisynth 2.6" branch

[ilhyfe]

it s in same place, but in "avisynth 2.6" branch

I must be blind or something. I only found http://avisynth2.cvs.sourceforge.net/avisynth2/avisynth_2_6/ and it's empty.

[Fizick]

http://avisynth2.cvs.sourceforge.net/avisynth2/avisynth/
open "Steaky Tag" listbox, select avisynth_2_6 instead of main.

If you need in CVS command not for Web inteface but for Tortoise CVS, i wil post it later

[ilhyfe]

[url]If you need in CVS command not for Web inteface but for Tortoise CVS, i wil post it later

Would be nice, though I use the command line CVS version (I don't like Tort...). Thanks.

[Fizick]

i have no idea about command line.
see here
http://forum.doom9.org/showthread.php?t=111104

i created separate module folder locally for avs 2.6,
and select appropriate tag (avisynth_2_6)

[ilhyfe]

Can you give me the command for Tortoise CVS then?

[Fizick]

Hmm, it is not command but method and settings.

1. Install TortoiseCVS
2. create any folder in your harddisk, for example avisynth_2_6 or avisynth26
3. right click mouse at empy place of this folder window
and select "CVS Checkout"
4. In popup window at "module" tab:
Protocol: Protocol server (:pserver:)
Server: avisynth2.cvs.sourceforge.net
Repositiry folder: /cvsroot/avisynth2
User name: anonymous
Module: avisynth

5. In next "Revision" tab:
select "Chose branch or tag"
Branch or tag: avisynth_2_6

(if you need in main (2.5.8) source, choose HEAD branch instead, in other local folder)

6. press OK.

What do you want to do with avisynth 2.6 source? :)
Could you help us with development?

[Wilbert]

command:

avs_v26: cvs -q checkout -r avisynth_2_6 -P CVSROOT=ext:WilbertD@avisynth2.cvs.sourceforge.net:/cvsroot/avisynth2

If you do it anonymously, i think that you need to use

avs_v26: cvs -q checkout -r avisynth_2_6 -P CVSROOT=pserver:anonymous@avisynth2.cvs.sourceforge.net:/cvsroot/avisynth2

[Wilbert]

@IanB,

posti reported and fixed a bug in TimeStretch:

http://forum.doom9.org/showthread.php?t=134290

[IanB]

@Wilbert (Moderator),

It helps if you approve the Attachment so I can read it to. :(

[Wilbert]

I approved it :)

[IanB]

@Wilbert, ... Ta!

Hmm, not an Avisynth plugin :confused:

I don't think our code has the problem.

Do we know where to get the pre-patched source for exact comparison.

[foxyshadis]

That's unrelated avisynth's timestretch, it's whatever's in reclock. Same name is all. If you look at the code, it's all a bunch of directshow junk wrapped around soundtouch.

[Leak]

Do we know where to get the pre-patched source for exact comparison.
IIRC it's distributed together with ReClock 1.7 beta <whatever was the last one>.

[ilhyfe]

Unfortunately I'm not a developer :). I just want to build a version from cvs and test it, instead of using the compiled version postet here last year.

The CVS thing worked so far, thanks.

[IanB]

I don't think our code has the problem.Confirmed, we don't have a problem.

[sh0dan]

@Wilbert: There doesn't seem to be anything changed within SoundTouch, only in the interface to ReClock.

(there is one change, but that seems to be a only to avoid compiler ambiguity)

[ilhyfe]

I successfully built version 2.6 but I can't encode a video with it. I tried to encode a mped2 stream with simple commands (mpeg2source(),crop(),spline16rezise()) and it seems it was a bit faster then v2.5.7 but after a few frames encoding stopped.

[IanB]

@ilhyfe, Now you know why there are no released versions. I know it is incomplete. Stick with 2.5.8, I do extensively test all that code before I check it in.

[20-40]

i have no idea about command line.

avisynth_2_6 with cvs.exe
cvs -d:pserver:anonymous@avisynth2.cvs.sourceforge.net:/cvsroot/avisynth2 login

<enter>

cvs -z3 -d:pserver:anonymous@avisynth2.cvs.sourceforge.net:/cvsroot/avisynth2 co -ravisynth_2_6 avisynth

[Ignus2]

Any news on the status of 2.6?
