Direct copy of pre-encoded file:

$ ffmpeg -i filename.mp4 -codec: copy -start_number 0 -hls_time 10 -hls_list_size 0 -f hls filename.m3u8

An example of recursion with Promises

A pattern for recursion with Promises - in this example, walking a directory structure.

readDirRecursive() is called with a starting directory and will itself return a Promise.
Internally readDir() is called and passed starting directory.
A list of directory items is returned by getItemList() as a Promise, which in turn is chained to getItemListStat() to stat each item to determine if file or directory.
Finalised list then passed to processItemList():
- Files are added to accumulating fileList array.
- Directories are added to readDirQueue.
