title: Why vscode does not include ffmpeg in its build?
body: <p>I want to create extension that enables video plays in webview on vscode workbench. </p>
  
  <p>I have already tried vid.canPlayType within Extension Development Host with various video formats, but none of them worked.</p>
  
  <p>Some developer said it will work with another nw.js project <a href="https://github.com/VSCodium/vscodium/issues/152#issuecomment-492050247" rel="nofollow noreferrer">here</a>, but I still cannot figured it out</p>
  
  <p>Why Vscode team does not include default FFMPEG codes in the electron build ?</p>
