TypeScript bindings for VapourSynth

Installation

yarn add vapoursynth-ts

Getting started

import { core, PyScript } from 'vapoursynth-ts'

// Like you would in the Python bindings
const source = core.lsmas.LibavSMASHSource('./haruhi_01.mkv')

// can also import a Python script
const myscript = new PyScript('./haruhi_01.vpy')
const myscript2 = new PyScript('./haruhi_01v2.vpy')

// Boring!!
const comp = core.std.StackVertical([
    myscript.getOutput(0).clip,
    myscript2.getOutput(0).clip
])

// Way better 👍
const bitOfGrain = comp.grain.Add(10, 15)

// Way more betterer 👍👍
const lottaOfGrain = comp.grain.Add({ var: 26, uvar: 12 })

source.setOutput(0)
comp.setOutput(1)
bitOfGrain.setOutput(2)
lottaOfGrain.setOutput(3)

Specifying core flags

import { core, CoreCreationFlags, setCoreCreationFlags } from 'vapoursynth-ts'

// Has to be set before any call to core has been done
setCoreCreationFlags(
    CoreCreationFlags.DisableAutoLoading,
    CoreCreationFlags.DisableLibraryUnloading,
    CoreCreationFlags.EnableGraphInspection
)

const clip = core.std.BlankClip()
