Usage

Example: download from training site

Run the following command in your terminal to download all the videos to the folder you are currently in. Substitute the example credentials with your own and supply a link to the course.

youtube-dl --username "[email protected]" --password "yourPassword" --verbose --sleep-interval 120 "link to course"

Example:

youtube-dl --username "[email protected]" --password "yourPassword" --verbose --sleep-interval 120 "https://app.trainingsite.com/library/courses/javascript-fundamentals/"

IMPORTANT

The argument --sleep-interval 120 is important. It means that the program will wait 120s (2 minutes) before it downloads the next video. If you don't use this flag the training site will ban you because you are doing too many requests under a short period of time.

We have blocked your account because our security systems have flagged your training site account for an unusual amount activity. This does mean a high volume of requests that are in the realm of a request every 10-30 seconds for a prolonged period of time.
