Avisynth+ plugin modernization efforts

[TurboPascal7]

As you might know, a part of Avisynth+ core team is working on plugins modernization, adding x64 support and other features. This thread is dedicated to discussion of those plugins. Some new plugins are also included.

General changes/rules
MMX/ISSE optimization paths are removed everywhere, replaced with SSE2/newer routines. C versions are added too unless specified otherwise.

YUY2 support is also removed if any work is required to support it. You can still use these plugins by converting your YUY2 clip to YV16, processing it with planar-only filters and converting back to YUY2 if you need. This conversion is lossless and fast.

Right now both Avisynth+ and Avisynth 2.6 are supported. Avisynth 2.6 support will be dropped at some point when Avs+ specific features are added - multithreading and >8bit colorspaces being obvious examples. Avisynth 2.5.8 is not supported.

All plugins are dynamically linked to vc110 runtime. Avisynth+ installer provides it for you.

VapourSynth, maybe?
Right now the answer is no. VapourSynth support is considered and might be added at some point in the future. For now - feel free to fork/take the code from anything you want, most plugins are/will be licensed under MIT.

How can I help?
Usual stuff - testing, discussing, updating some plugins that aren't included yet. Feel free to join our IRC channel for faster communication. Writing documentation would be very helpful too, especially for RgTools.

What's next?
Current "roadmap" can be found here. It's somewhat messy and does not mean that these plugins will be ported in any particular order, but it does show what's considered right now and what's not.


Plugins listed in random order. Only those hosted under the AviSynth organization on GitHub are included.

Vinverse
Source / binaries. Opt parameter is removed. New Vinverse2 function provides a fast implementation of this script.

TMaskCleaner
Source / binaries. A really simple plugin, never released before. It is basically mt_hysteresis with all areas less than length pixel discarded. Useful for some mask cleaning.

TColorMask
Source / binaries. A really fast implementation of ColorKeyMask for YUV colorspaces. Never released before.

SangNom2
Source / binaries / thread. Same "old" SangNom2. Additional info can be found in its thread. Does not have a C version yet.

MSharpen
Source / binaries. Same old MSharpen. Output for planar colorspaces is not exactly identical because of a bit different blurring routine. YUY2 support removed, all planar routines optimized for SSE2, a few old bugs fixed. External file configuration is no longer supported.

RgTools
Source / binaries. Replacement of some kassandro's plugins. 24 modes of Removegrain, 24 modes of Repair, both modes of VerticalCleaner and all variations of Clense are implemented. No more dlls mess - a single dll with dynamic dispatch is provided. Some routines might be slightly less efficient than original, some are faster. Output of some modes of RemoveGrain is not exactly identical to the original because of some rounding difference. Other functions should be identical.

Deblock
Source / binaries. Simple deblocking filter. No significant changes, simple refactoring. Should still be noticeably faster thanks to better compilers. YUY2 support removed, useless mmx and isse parameters too. This filter is licensed under GPL.

MedianBlur2
Source / binaries. Simple median filter similar to MedianBlur (function name is still MedianBlur). Theoretical runtime complexity per pixel is constant, meaning that the filter has same performance on any radius. Additional info here.

Checkmate
Source / binaries. Update of the old checkmate plugin, used for dot crawl removal. Better performance, less bugs, a bit lower precision. The difference is hardly noticeable when you're looking for it.

Masktools2
Source / binaries. A fork of masktools2. The only plugin compatible with avisynth 2.5.8 for now. More info in this post.

Average
Source / binaries. The good old Average plugin but a bit faster and with some additional sanity checks.
