Adding global OPT_AllowFloatAudio=True to your script enables WAVE_FORMAT_IEEE_FLOAT audio output.
Explicitly request all the channels available in the audio stream [acm AC3]
Explicitly try to request float, 32 bit then 24 bit samples from the audio codec.
Accept raw audio streams of type WAVE_FORMAT_IEEE_FLOAT.
Added installer option to add "Avisynth Script" item to Explorer shell for new .avs file creation.

Optimizations

SubTitle() releases all resources when the last frame of the clip is rendered.
SubTitle() releases GDI resources after text map is created.
ApplyRange() only builds 2 chains instead of 3.
Changes
Map file is now generated for release builds.
ConvertTo*() and GreyScale() now accept "Rec601" as a valid matrix name.
DirectShowSource.dll upx'ed.
Upgrade internal copy of SoundTouch library to 1.3.1.
SoundTouch now available in RelSym build.
Animate Integer arg enumeration no longer rounds toward positive infinity. Both positive and negative enumerations are identical. i.e. For Animate(0, 10, "Foo", 0, 0, 10, -10), Foo's arg1 = -arg2 for all frames.
Selecting associate open with Notepad with .avs files in the installer now also includes .avsi files.
The Installer now pushes a recovery dialog box when unwritable files are encountered during an install. The user may manually correct the problem and retry installing that file.
SetMemoryMax() minimum now 4Mb instead of 16. (Tritical)
Remove 50 plugin auto prescan load limit. (Tritical)
COM QueryInterface calls now return S_OK instead of NULL.
Bracketless call of argless function now get a cache. (Tritical)
Over-range numbers now raise a compile time exception.
xxxFPS(float) now uses continued fraction to generate a minimal rational pair. (Raymod2)
ChangeFPS(linear=true) now raises a compile time exception if the speed change ratio is > 10.
ConvertFPS() blend mode works for all pixel formats. (Tritical)
Info() retrofit of 2.60 updates.
TCPDeliver.dll upx'ed.
RGB ColorBars +Q and -I bars, Hue is now correct, Luma is NOT zero to achive this.
AVISource Audio no longer limited to 2 channels.
SaveString memory blocks are now 32 bit aligned.
Default planar chroma planes mod 16 aligned. See SetPlanarLegacyAlignment().


Download from Sourceforge,

Edit : stable release is out now. See below.

The only thing I am wondering is that with the new ver close to the production release, are the external filter authors also working on releasing their filter with this ver support and optimizations.

It depends on the author of course but as you can see, some of them are actually working on the avisynth code itself (tritical...).

Stable release is out. No change since RC3 but for people that stil don't have any 2.57 version, take it ! :-)

Nice!
Thanks Phil, I was still using 2.56.

Be sure to check your common applications before you actually start using it as default.

DVD-RB currently does not support ver 2.57, there will be many others also.

It works perfectly with it (both free en pro).

What problem do you have ? And with wich other app ?
I don't see what can be blocking in 2.57 that was not in 2.56. The way the fps is determined perhaps ? I had some suprise this this too.

I read comments from JDobbs, to stick to ver 2.5.6 since the new version was not tested with RB. Although I have myself not tried it, but trust the authors opinion.

Ok, it's just a matter of beeing safe. I can testify for them so : it's working great and well :-).

Read here for some problems with avisynth 2.5.7/filters with AQMenc as posted by an end user.

Let us know if they identify a specific filter.

Post is updated its the Spline and Lanczos resize functions with AQMEnc.

As said by Marvelix, it's weird to see an internal function that screw up only one app (AutoQMatenc). And moreover, to have something implemented a long time ago (lanczos) and IMHO not changed between 2.56 and 2.57 to introduce such problem 8O

Anyway, I did and will never use AQE :lol:

another one from the author referencing DVD-RB and Avisynth new ver.

I encoded A LOT of video using avisynth 2.5.7 with always the same script and today I fall on the bug :

Problem solved with avisynth2.5.6a.

Out of interest, what was the bug - I can't see the image at all..it doesn't load.

Sorry, error with my imageshack account. I fixed it and I think now you can clearly see what is the bug :)

She is not behind a fence, is she?. :?

No, she is not ;-)

I thought so too :lol:
