// Both variants come with absolute error bounds and a reversibility and monotonicity

// implementation provided below, and the test driver checks all floats exhaustively.

# YouTube playlist audio retreiver and iTunes-compliant podcast XML generation tool.

# This script will download each video file from the specified YouTube playlist, losslessly extract
# the audio, delete the video, and ultimately produce an iTunes-compliant podcast XML with the
# appropriate metadata, including chapter markers (if provided in the description). If you run the
# script again, only videos that haven't already been converted will be downloaded, allowing you to
# schedule the script to run as often as needed without stressing your internet connection or
# hard drive space. After generating the files and xml, you can easily host them on a local server
# in order to use them with iTunes or your favorite podcast aggregator -- but that's beyond this
# script's jurisdiction.

# GDC Vault videos can't be watched on mobile devices and this is a very sad thing indeed!
# (Note: this has changed for GDC2013, which lets you watch raw MP4 streams. Kudos!)
# This script is designed to circumvent this by downloading the lecture and slideshow
# videos which can then be re-encoded into whatever format you wish. Obviously, you
# won't be able to do this without access to the Vault. This is strictly for the
# convenience of legitimate Vault users!

# Note: this code is rather flimsy and was written as fast as possible for my own personal use.
# The code only works for the most recent GDC Vault videos, since they all use the same player
# format. If the XML format used to run the player is changed (as it  has in the past), the code

# This script continues the work of gdc-downloader.py and actually combines the video and audio
# into a single video file. The underlay.png file specifies the dimensions of the video.
# Personally, I use an all-black 1024x768 rectangle for optimal iPad viewing.

# As with gdc-downloader.py, code quality is crappy and quickly assembled to work for my
# nefarious purposes.

# Usage is as follows:
#
#   gdc-encoder.py [video name] [video path] [output name] [GDC name]

This is based on instructions by @Capn_Andy (apparently now @SnugglePilot), who was 
pointed there by @Chaklapak. I implemented this the first time April 17, 2016, with 
some updates to make it work for Early Access (the original version gave me just the 
"Early Access Review" as review text). This version here is an update from April 30, 2017 
which was long overdue because my previous RegEx-statement mixed things up quite a bit, 
probably due to Steam changing the format a while back, resulting in the same reviews 
popping up in the Slack channel over and over, with authors, recommended / not recommended 
and the actual reviews all mixed up.

Setup:
1. Index buffer containing N quads (each 2 triangles), where N is the max amount of spheres. Repeating pattern of {0,1,2,1,3,2} + K*4.
2. No vertex buffer.

Render N*2 triangles, where N is the number of spheres you have.

Vertex shader:
1. Sphere index = N/4 (N = SV_VertexId)
2. Quad coord: Q = float2(N%2, (N%4)/2) * 2.0 - 1.0
3. Transform sphere center -> pos
