PoliWebex

If you are not familiar with terminal, you can use this browser extension to download WebEx videos directly from the webpage: https://github.com/jacopo-j/WebXDownloader

If you need to download multiple videos at once and/or prefer a faster download through aria2c, go ahead with this project 😉

GUI Version: https://github.com/yuyu-19/PoliDL-GUI

Saves WebEx videos uploaded by Politecnico di Milano.

Features:

• Interactive SPID login (but the username and password are saved)
• Download entire courses with the webeep url (https://webeep.polimi.it/course/view.php?id=XXX)

PREREQS

• Node.js: above v14.0.
• 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.

Windows Installation instructions

(On others OS is pretty much the same)
N.B: ffmpeg.zeranoe.com closed since Sep 18, 2020. If you are following the video tutorial, download ffmpeg from another source available on ffmpeg site (nightly build is no more required)

This tutorial comes from my other project PoliDown. The installation process is the same, just use clone this repo (and not PoliDown repo) and write "poliwebex" where in the video appear "polidown"

USAGE

• Clone this repo
• cd into the cloned folder
• npm install to install dependencies

Multiple videos download:

$ node poliwebex -v "https://politecnicomilano.webex.com/webappng/sites/politecnicomilano/recording/play/VIDEO-1" "https://politecnicomilano.webex.com/webappng/sites/politecnicomilano/recording/play/VIDEO-2"

Download from TXT file (one link each line):

$ node poliwebex -f "/my/path/here/links.txt"

Output directory (relative or absoulte path):

$ node poliwebex -v "https://politecnicomilano.webex.com/webappng/sites/politecnicomilano/recording/play/VIDEO-1" -o "/my/path/here"

Replace saved password

$ node poliwebex -p MYNEWPASSWORD -v "https://politecnicomilano.webex.com/webappng/sites/politecnicomilano/recording/play/VIDEO-1"

Download password-protected video (could also omit the argument and input it manually)

$ node poliwebex  -v "https://politecnicomilano.webex.com/webappng/sites/politecnicomilano/recording/play/VIDEO-1" -w PASSWORD

Scale timeout values by a factor X (integer or float value). Really useful for slow connections while performing login operations

$ node poliwebex  -v "https://politecnicomilano.webex.com/webappng/sites/politecnicomilano/recording/play/VIDEO-1" -i X

Do not use system keyring to save the password:

$ node poliwebex -v "https://politecnicomilano.webex.com/webappng/sites/politecnicomilano/recording/play/VIDEO-1" -k

You can omit the password argument. PoliWebex will ask for it interactively and then save it securely in system's keychain for the next use.
