PoliWebex

Saves WebEx videos uploaded by Politecnico di Milano.

Features:

• PoliMi autologin
• Multithreading download through aria2c

PREREQS

• Node.js: anything above v8.0 seems to work.
• aria2: this needs to be in your $PATH (for example, copy aria2c.exe to c:\windows). PoliWebex calls aria2c with a bunch of arguments in order to improve the download speed.
• ffmpeg: a recent version (year 2019 or above), in $PATH.
