(DEPRECATED) A mostly drop in elligator2 for ed25519-donna.
There used to be something that resembled an Elligator2 implementation here ported from agl's
Go code. The implementation is unmaintained and has severe issues (as pointed out in a comment),
and should not be used for anything.

Encoding video for the web

Encoding Video

Installing

Install FFmpeg with homebrew. You'll need to install it with a couple flags for webm and the AAC audio codec.

brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aac --with-opus

Bare minimum Chrome extension to inject a JS file into the given page when you click on the browser action icon. The script then inserts a new div into the DOM.
// this is the background code...
// listen for our browerAction to be clicked
chrome.browserAction.onClicked.addListener(function (tab) {
// for the current tab, inject the "inject.js" file & execute it
chrome.tabs.executeScript(tab.ib, {
file: 'inject.js'
});
});

Convert videos to proper formats for HTML5 video on Linux shell using ffmpeg. Will probably convert this to a bash script later, but for the time being, here's some examples. Not sure there have actually sensible dimensions and bitrates for web video.
