I should have written this in the cover-letter, my bad.
pycryptodome is needed for the hlsative downloader, ffmpeg adds the 
ability to merge video and audio files downloaded separately by 
youtube-dl and removes the following warning:
WARNING: You have requested multiple formats but ffmpeg or avconv are 
not installed. The formats won't be merged.

Have a look in the NixOS derivation for more information on 
dependencies:
