Feature: Create Image thumbnail from uploaded video

[ThatGuySam]

The thinking is that you would start the video upload from Swift, PHP, etc and get an image file as the response

Here's a theoretical example usage with Javascript and Fetch API

const videoInput = document.querySelector('input[type="file"]')

const data = new FormData()
data.append('file', videoInput.files[0])

fetch('https://vumbnail.com/upload.jpg', {
  method: 'POST',
  body: data
})

This could potentially be very fast, maybe less than 500ms, if the app returned an image as so soon as it has the data for any whole frame.
