Vidar for Node

Sometimes it's useful to use Vidar in Node. This package is a wrapper of Vidar that serves that purpose.

Usage

vidarNode(() => {
  // You can access inputs as html elements and pass them to Vidar as usual.
  const image = document.getElementById('input1') // <img> element
  ...
  movie.exportRaw()
    .then(window.done)
// Tell Vidar Node what inputs to load with { id: path }
}, { input1: 'path/to/image.png' }, 'output.mp4')

Documentation

vidarNode(vidarFunction, inputSources, resultCallbackOrPath[, page])

• vidarFunction (string) - Function to run in the puppeteer page. vd and done are exposed as globals (accessed as properties of window)
  • window.done(exportedBytes) - Process the exported movie (resolved value of Movie#exportRaw), by either writing to resultCallbackOrPath if it's a string or executing it if it's a function
• inputSources (Object<string, <string|Object>>) - the input assets, mapped from id to path or raw data. If the input is provided as raw data, it should be an object with the following properties:
  • type (string) - the MIME type of the input source
  • data (Buffer)
• resultCallbackOrPath (function|string) - Determines what to do when window.done is alled in vidarFunction. If it's a string, it is treated as a path and the movie is written to it. If it's a function, it is called with one argument exportedBytes.
• page (Page) - the puppeteer Page to use. Defaults to a page created by a new browser.

Runs vidarFunction in a puppeteer page. Each input source is converted to an html element (<img>, <audio> or <video>). The output is either written to the path or the callback is executed, depending on the type of resultCallbackOrPath.
