Bunny CDN "DRM" Video Downloader

A Python class for downloading Bunny CDN's "DRM" videos using yt-dlp.

Requirements

You'll need to install yt-dlp and requests modules in your Python environment.

pip install -r requirements.txt

It is also better to have FFmpeg installed on your system and its executable added to the PATH environment variable.

Usage

To try the script for testing and demonstration, simply paste the iframe embed page URL at the bottom, where indicated between the quotes, as well as the webpage referer, and run the script.

python3 b-cdn-drm-vod-dl.py

Embed link structure: https://iframe.mediadelivery.net/embed/{video_library_id}/{video_id}

Expected Result

By default:

• the highest resolution video is to be downloaded. You can change this behavior in the main_playlist function located under the prepare_dl method.
• The video will be downloaded in the ~/Videos/Bunny CDN/ directory. This configuration can be changed by providing the path argument when instantiating a new BunnyVideoDRM object.
• The video file name will be extracted from the embed page. This can be overridden by providing the name argument .

Please note that the video format will be always mp4.

Explanation

The idea is all about simulating what's happening in a browser.

The program runs a sequence of requests tied to a session object (for cookie persistence and connection pooling) first of which is the embed page request, from which information are extracted such as the video name.

After that, the download link (an HLS/M3U8 URL) is ready to be fed to yt-dlp to download the video segments, decrypt them (as Bunny CDN's "DRM" videos are encrypted with the AES-128 algorithm), and merge them into a single playable video file.
