VapourSource

VapourSynth Script Importer for Avisynth2.6/Avisynth+

version:

0.2

requirement:

VapourSynth r30 or later

AviSynth2.60 / Avisynth+MT r2005 or greater

Windows Vista sp2 or later

Microsoft Visual C++ 2019 Redistributable Package

SSE2 capable CPU

usage:

as follows.:

VSImport(string source, bool "stacked", int "index")

source   - input script path.
stacked  - if this is set to true, MSB/LSB will be separated and be stacked vertically (default: false).
index    - index of input clip(default:0).
prefetch - request more frames in advance. By default will use amount of dedicated core threads from Vapoursynth.


VSEval(string source, bool "stacked", int "index", bool "utf8")

source - vapoursynth script.
stacked, index and prefetch are same as VSImport.
utf8   - if this is set to true, source is assumed to be UTF-8 encoded (default: false).
