Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

avisynth

Avisynth bindings for NodeJS with a strong focus on ease-of-use.

AppVeyor badge CodeClimate badge coverage badge dependencies badge

A node module that you can use to process videos, images and sound with Avisynth, in a self-contained package.

  • No dependencies
  • Top code quality
  • 100% code coverage for all files down to branches and statements

It currently only works in Windows (like Avisynth itself), but it may be possible, in theory, to add Linux support via Wine.

install

npm install -g avisynth

usage

It can be used both by scripts as well as from command line (also not requiring Avisynth to be installed, and possibly helpful for shell scripts in other languages).

Node usage:

var avisynth = require('avisynth');
var script = new avisynth.Script(); // Omitting "new" is also ok
script.code = 'Version()'; // Can also be passed to the constructor
script.sharpen(1); // Direct plugin and built-in calls
script.renderFrame('foo.png', function(err) { // Time offset optional.
    console.log(err || 'foo.png saved!'); // Easy frame rendering.
});
script.run(function(err) {}); // Runs the script (with no output).
script.lint(function(err) {}); // Validates the Avisynth code.
// Still planning on adding more API, specifically video encoding.

Command-line usage:

avisynth-js info path/to/script.avs # Returns video info as JSON
avisynth-js lint path/to/script.avs # Validates a script, also JSON

Sample output for info:

{
    "width": 1280,
    "height": 720,
    "ratio": "16:9",
    "fps": 29.97,
    "fpsFraction": "30000/1001",
    "videoTime": 3600,
    "frameCount": 107892,
    "colorspace": "YV12",
    "bitsPerPixel": 12,
    "interlaceType": "field-based",
    "fieldOrder": "TFF",
    "channels": 2,
    "bitsPerSample": 32,
    "sampleType": "float",
    "audioTime": 3600,
    "samplingRate": 48000,
    "sampleCount": 172799827,
    "blockSize": 8
