Description

Simple and hacky program to download a udemy course, has support for DRM videos but requires the user to aquire the decryption key (for legal reasons).

Requirements

1. You would need to download ffmpeg and mp4decrypter from Bento4 SDK and ensure they are in path(typing their name in cmd invokes them).

Usage

quick and dirty how-to

1. you need to open the network tab, and find the index.mpd file url
2. open the dashdownloader_multisegment.py file and replace mpd url with the url
3. Change the video title and output path to whatever you want the video to be called 175. Inverse Transforming Vectors is what your would replace
4. rename keyfile.example.json to keyfile.json
5. open keyfile.json and enter the key id and decryption key for the video
6. run python dashdownloader_multisegment.py in the terminal to start the download. make sure you have ffmpeg and mp4decrypt installed in your path
