LeccapDownloader

An automated lecture recording downloader designed to work with https://leccap.engin.umich.edu.

This implementation downloads selected lectures for a given course into a given directory.

Requires Google Chrome/Firefox/Edge/Safari, python3, and Selenium (pip install -r requirements.txt).

Setup

1. Download the most recent Web Driver for your browser and operating system
   • ChromeDriver: https://sites.google.com/a/chromium.org/chromedriver/downloads
   • FirefoxDriver (Marionette): https://github.com/mozilla/geckodriver/releases [NOT WORKING WITH QUANTUM]
   • Edge: https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/ [Will NOT work unless source code is modified]
   • Safari: https://webkit.org/blog/6900/webdriver-support-in-safari-10/ [Will NOT work unless source code is modified]
2. Extract the WebDriver zip and add the binary into your path
   • Alternatively, just put the binary (chromedriver or geckodriver) in the same folder as leccap_dl.py
   • Or, specify location to chromedriver or geckodriver using -wdc or -wdf respectively
3. pip install -r requirements.txt
   • This installs:
     • selenium: needed to navigate browser without user input
     • requests: needed to download video files
     • clint: needed for progress bar on downloads

Usage

python leccap_dl.py

python leccap_dl.py [-h] [-t] [-i COURSE_UID] [-o OUTPUT_DIRECTORY] [-wdf WEB_DRIVER_FIREFOX] [-wdc WEB_DRIVER_CHROME]

Name	Type	Description
-h [--help]	flag	Show help message
-t [--threaded]	flag	Optional. Runs each download in a separate thread. Minimal performance increase, no progress bar.
-i [--course-uid] COURSE_UID	string	Optional. The unique course identifier, which can be found at the end of the leccap URL. Note that this is not the same as the unique identifier for an individual lecture recording. This allows for quick downloads if the course uid is known. If not, a menu of classes will appear.
-o [--output] OUTPUT_DIRECTORY	string	Optional. The directory to output downloaded files to. Defaults to current directory.
-wdf [--web-driver-firefox] WEB_DRIVER_FIREFOX	string	Optional. The location of the geckodriver. Defaults to PATH then current directory if not provided.
-wdc [--web-driver-chrome] WEB_DRIVER_CHROME	string	Optional. The location of the chromedriver. Defaults to PATH then current directory if not provided.
