ReEcho: an echo360 lecture downloader

Features:

• Lesson selector for a given course
• Fast and high quality download
• Audio and video muxing
• Creates a .mp4 file of your lecture

Setting up the environment

This program requires command line ffmpeg and python3.7+. Tested on OSX and Linux. I have strong doubts it would work on Windows in its current form.

For installing ffmpeg, see this link. On OSX, you can use brew if you have it:

brew install ffmpeg

To set up the python environment, I recommend using a virtual environment:

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Usage

To use the program, you need to provide a 'curlfile', i.e. a file containing the relevant curl command to access the home page of your lecture course.

The easiest way to obtain this is to login and visit the home of echo360 for your course. Open the Network tab of the developer tools, and refresh the page. The top entry should read something like

Status	Method	Domain				File 		Cause
----------------------------------------------------------------------	
200		GET		echo360.org.uk 		home 		document	...
...

Right click on this, and under Copy select Copy as cURL. Paste this into a file, name it whatever you like, and then execute the downloader using

python . ./[path_to_curl_file]

The downloader script will use the cookie headers to automatically login as your user account, and display your courses.

Notes

This has only been tested on the one course I have access to, which as of date of writing only has one lesson upload. I've tried my best to anticipate the generalization of the code, but there be errors since I had a very limited range of tests available. Please contact me with logs so I can patch them.

Thanks and enjoy :)
