Download DRM-Protected Videos from Login-Restricted Sites
Short Introduction
This guide shows how to download DRM-protected video content from sites that require login (like Careerwill). It simplifies the process using browser tools and open-source software that work with encrypted video streams.
Simplified One-Line Flowchart
Log into browser ➔ Find video stream URL ➔ Decrypt and download with tools
Easy Step-by-Step Method
Step 1: Use a supported browser like Chrome or Firefox
- Open the site in your browser and log in normally.
- Keep the video ready for playback.
Step 2: Open Developer Tools (F12)
- Go to the “Network” tab.
- Start the video and filter by “m3u8” or “playlist”.
- Copy the full
.m3u8
link.
Step 3: Download the video with yt-dlp
- Run this command in a terminal:
yt-dlp "<paste the full m3u8 URL here>" --cookies-from-browser chrome
- This grabs cookies from your logged-in browser and handles encrypted streams.
Step 4: Install ffmpeg if needed
- yt-dlp needs
ffmpeg
to merge audio and video. - Download from: https://ffmpeg.org/download.html
Step 5: (If encrypted) Extract license keys using N_m3u8DL-RE
- Download from: https://github.com/nilaoda/N_m3u8DL-RE
- Use it to fetch the video and decrypt it automatically:
N_m3u8DL-RE.exe "<m3u8 URL>" --auto-select --log-level DEBUG --binary-merge
Step 6: Check for Widevine encryption
- If the stream uses Widevine DRM (common for protected education platforms), you’ll need a license key.
- Tools like Widevine L3 Decryptor (use at your own risk) may be used in a dev environment.
Quick Tips (Optional)
- Use the
--no-playlist
flag in yt-dlp to avoid downloading extra items. - Some sites hide stream URLs behind JavaScript—reload the page if nothing appears under “Network > m3u8”.
Important Notes
- Downloading DRM content may violate terms of service; proceed responsibly.
- Many tools rely on your system’s browser session for authentication—do not log out while downloading.
- Widevine-protected content is extremely difficult to decrypt without legal keys.
- Avoid shady third-party “decryptors”—they may contain malware or spyware.
