Software » Video Frameservers » Avisynth 2.6.0 / 2.6.1 Alpha

Interim Avisynth 2.6.1 alpha release.
=====================================
This release is intended to be near feature identical to 2.6.0

There are currently 3 build versions, all should be bug identical.

These versions do not include the local help files so as to speed
the fast swapping between versions by over installing the required
version. The 2.6.0 local help is still current.

The alpha installers do not provide installation of runtime components.
The user must download the relevant packages from Microsoft and install
them.

All versions now ship with DevIL 1.7.8, which needs VC 2K5 runtimes.
DevIL.dll is now delay loaded, so Avisynth.dll can be used without
it, in which case ImageReader/Writer would support only ebmp mode.
AviSynth_20160517_VC6.exe
Uses the systems MSVCRT.dll only.
There is no longer any dependance on msvcp60.dll
Requires a processor supporting MMX instruction set.

AviSynth_20160517_VC2005Exp.exe
Needs the VC 2K5 runtimes.
Requires a processor supporting MMX instruction set.

AviSynth_20160517_VC2008Exp SSE2.exe
Needs the VC 2K8 runtimes.
Requires a processor supporting SSE2 instruction set.
Users encountering problems should compare the behaviour of each version
and also the official 2.6.0 version. Different behaviour between 2.6.0 and
2.6.1VC6 are likely to be coding errors. Different behaviour between the
VC6 and 2K5 or 2K8 version are probably caused be incompatibilities in the
development environments.

During development most incompatibilities have shown up in the error
reporting and the error handling. The VC 2015 Community build environment
version currently fails the acceptance tests and has been withdrawn from
this release.

As you make mistakes writing your Avisynth scripts please ensure the error
messages are appropriate and the line number and column counter are consistant.
Erroneous scripts that cause inconsistant error reporting gratefully accepted.
