Challenge Overview

Competition Task Overview

In this challenge we'd like to extend the NGINX module we built in the previous challenge.

The module utilizes the VideoLAN libVLClibrary to transcode a source stream to a specified output format through VLC.

Requirements

  • Add support for progressive MP4, the API should follow same pattern as HLS and Pseudo-HLS (RESTful)
  • Progressive-mp4 is a made up hack. There's no standard or suggested way to implement it because of that. We belive what we need to do is to define the metadata, return that first and then pipe the VLC stream down the same pipe. It might take some lower level socket manipulation to accomplish this but it should be doable, check http://www.adobe.com/devnet/video/articles/mp4_movie_atom.html for more details. I think basically it involves putting the metadata at the beginning of the stream so that players can play it without waiting for the rest of the video stream.
  • To verify that the progressive MP4 produced by your code works, we should test transcoding from a live camera that is continuously viewable, the transcoded MP4 should work on a regular video player.
  • Make sure the updated code works on Ubuntu (AWS)

Versions & Environments

  • NGINX Version: 1.5.7
  • VLC version 2.1.5
  • Ubuntu 14.04
