AviSynth 2.06 Released

[sh0dan]

Many new changes. The most visible change is the new installer.
Most known bug have been crushed in this release, including some very old ones, so this is the chance for everybody to upgrade! There has been most emphasis on stability and useability for this release. Hope you feel so too!

Changelog:

New:
- Added LanczosResize which uses the Lanczos3 algorithm - it provides better quality than BicubicResize in many cases.
- New ResetMask() filter: sets the mask to "all-opaque" (RGB32 only).
- Added optional pixel_type parameter to AVISource and siblings to force a decompression format (YUY2, RGB32 or RGB24).
- Added optional left and right parameters to Letterbox - parameters are placed after the existing to preserve compatibility.
- Added EnsureVBRMP3Sync(clip), to avoid desync of VBR-compressed mp3-soundtrack. This will slow seeking down considerably, but is very useful when using trim() for instance. Always use before trim().

Changes:
- Added installer/uninstaller. No more need to fiddle with .reg files and regedit.
- Default alignment is now 16 bytes, which should be faster on P4.
- Added example scripts.
- Made forward seeking fallback code in DirectShowSource files - it will not freeze anymore, just be very slow, since it has to decode all inbetween frames!
- Optimizations to YUY2 BicubicResize/BilinearResize.
- Better rounding precision in BicubicResize/BilinearResize.
- ChangeFPS() now changes the framecount (thanks to Xesdeeni).
- AVI files, that contains an invalid first frame are now rejected - there is no way of handling this situation gracefully. Segmented AVI's automatically skip these segments, and will NOT return an error.
- Better parameter checks on Crop() and LetterBox().
- AviSource always returns last valid frame on decompression errors.
- Added check for invalid frame 0 (mostly seen in SegmentedAviSource()).


Fixes:
- Fixed potential crashbug in Resize - real fix instead of previous hack.
- Fixed bug in RGB32 greyscale, when with not divideable with 2.
- Fixed Trim, so negative values works as documented.
- Fixes to plugin autoloading: - freezed when invalid dll encountered, was locking files unnecessarily, now also loads avisynth plugins with VDF extension.
- Fixed wrap at right side of picture in RGB BicubicResize()/BilinearResize().
- Fixed another Chroma wrap issue in BicubicResize()
- BugFix: Fixed crashbug in Resize functions on some machines.


As usual the release binaries can be grabbed from http://sourceforge.net/projects/avisynth2/


Thanks to all here who tested, and took time to give feedback!

Shodan, could you please have a look on "Warpsharp filter 0911a" thread; I wrote a post concerning warpsharp.dll. I'm pretty sure that the problem comes from that dll; but we never know, maybe an additional control could be done from avisynth (if possible) on plugins in order to avoid that kind of crash ?

Regards,

FuPP

Small point but the colour of the Version() command isn't green - its some funny shade of yellow/orange - is this a bug or a feature

Finally!

Well done!

[cult]

I see yours also as grey...My eyes,my monitor.whats wrong??

[Koepi]

Dunno what's wrong, it shows up as a pastel yellow here

there is still the bug I mentioned the other topic, when left + right using Crop is not a multible of 4, there is a green line on the right side

[HarryM]

Excellent result! Congrats!

v2.06 is about 4% faster (overall 'mpeg2 to xvid' encoding process, BicubicResize using) and final size of xvid is about 1% smaller!!!

Next, next and next optimizations, please...

[cult]

do you mean the letters are yellow?

Yes, the letters are pastel yellow on my system also when viewing the version info.

Edit- Has anyone else had problems with TMPEG opening AVS files up since installing AVS 2.06? I'm constantly getting the error "dont know what LoadPlugin is". And ideas? This is a 3 day old Win2k install, so it fairly fresh.

[falcon_b]

Could somebody tell me what to do?

CCE can't open the new AVS scripts. It just terminates if I want to open it. Virtualdub also has some problem because if I try to close the file it gives me an error with a debug window.

Any idea?

[baz00ie]

Yeah, i had the same problem falcon_b... I don't know why it happens, but, to deal with it i did the following:

Moved the "avisynth.dll" from the ..\windows\systyem folder then uninstalled the program.

Next, put the "avisyth.dll" back to the ..\windows\system folder and then run the original "install.reg" file.... worked like a charm.

I know these guys will work out the kinks in the days to come,... they do good stuff.

take care

[SILICON]

It`s my script:
-----------------------------------------
LoadPlugin("C:\DVD2CVCD\MPEG2DEC\MPEG2DEC.dll")
Mpeg2Source("C:\DVD2CVCD\FILM.d2v")
SetMemoryMax(40)
-----------------------------------------

Avisynth v2.06, MPEGdec (tbarry, original or FDMark)

It crass with any warning.

If I delete "SetMemoryMax(40)" it works ok.
The TMPGENC don´t hang the PC. I say "Script reaturn ane invalid value"

a few minutes before, it works ok.

Soory, but i can´t give us more info :-(

[JohnMK]

I'm assuming that it takes the same mod 2 as bilinear/bicubic, and that this will produce quality output?

[jarthel]

why not provide a zip file sh0dan? Some like me would prefer to do it manually.

[meleth]

hrm is it just me or has anyone else had problems with 2.06 and it opening the scripts at a really high resolution when you try to watch a script? The version example alone starts in a resolution way above 1280*1024.

[sh0dan]

Regarding version() - yes I changed the color. I thought the original was... well not much much of an eyepleaser, so it's now lightyellow/Grey.

@jarthel:
The CVS releases will be dll-only - wait for the first new release, and grab it there then

@SILICON:
Try using setmemorymax() as the first parameter - does that help?
Try other scripts.

@JohnMK:
Yes, lanczosresize is mod 2.

@meleth:
Could you post a screenshot of Virtual Dub "File Information" on a clean Version() example. Are you using vobsub?

@FuPP:
See the thread you mentioned.

[stax76]

am I the only one with a green line? The second thing I don't know if this is a Windows or a AviSynth Problem, but quite a lot people seem to have this problem, I got about ten reports until now and my program is not very popular so far, here is the topic
