Originall From: Posted 2015-05-29 http://ubwg.net/b/full-list-of-ffmpeg-flags-and-options

This is the complete list that’s outputted by ffmpeg when running ffmpeg -h full.

usage: ffmpeg [options] [[infile options] -i infile]… {[outfile options] outfile}…

Getting help:
    -h — print basic options
    -h long — print more options
    -h full — print all options (including all format and codec specific options, very long)

/*
 Small demo to show chaining of API calls. We're using these APIs:
 https://weathers.co for current weather in 3 cities, and
 https://api.github.com/search/repositories?q=<term> to search GitHub repos for
 the 'hottest' city. For example, we'll grab weather for 3 cities, pick the hottest one,
 then hit GitHub with a search for repos that have that city's name. A bit nonsensical
 but I just wanted to demonstrate using the results of one API call to populate a second.

 The problem we're trying to solve is that the API calls are asynch, and one of them
 (getCityTemperatures) loops through several asynch calls (one for each city), and they
