These are notes while researching a way to convert a browser/website to a stream. This could be used for Facebook Live or for webrecording. TL'DR:

• I started with Phantomjs - but that didn't support the html5 video tag
• SlimerJS supports it, but there is no way to record audio directly (though this might come from desktop audio)
• So I moved to research ffmpeg/X11/XVFB to record it with linux which works
• But ffmpeg has no easy way to mix streams/overlays to I moved on to OBS with overlay browser support
• I started researching options OBS in docker and it needed best a GPU , so I move to nvidia-docker
• And so came across building game servers on EC2/AWS using GPUs and managed to run OBS inside of GPU g2x.large machine
• I tried streaming to twich , which works great and managed to restream 4K 60FPS youtube on an AWS instance
• Remote control works through OBS-Remote but OBS has kinda limit in types of features

Clustering: The basics

The trick? pass the file descriptor from a parent process and have the server.listen reuse that descriptor. So multiprocess in their own memory space (but with ENV shared usually)

It does not balance, it leaves it to the kernel.

In the last nodejs > 0.8 there is a cluster module (functional although marked experimental)

• http://nodejs.org/api/cluster.html
• Simple cluster example:

#!/bin/bash
set -ex

# This scripts allows you to upload a binary to the iTunes Connect Store and do it for a specific app_id
# Because when you have multiple apps in status for download, xcodebuild upload will complain that multiple apps are in wait status

# Requires application loader to be installed
# See https://developer.apple.com/library/ios/documentation/LanguagesUtilities/Conceptual/iTunesConnect_Guide/Chapters/SubmittingTheApp.html
# Itunes Connect username & password
