Every month, Linux Academy releases courses for free. I'm a very busy
college student and don't have time to whirl through everything I want
to before it goes behind their paywall again so I figured out how to
download a course or two every month using
youtube-dl.
Setup
- Install
youtube-dl - Make sure you have a browser handy
- Create a community account on Linux Academy
- Get some food
- Maybe a drink
- Sit back down in your chair
- Spin around a bit
- Read on
Downloading
- Log into your account
- Pick the course you want
- Open the developer console and go to
Network(Ctrl+Shift+E in Firefox) - You'll want to select
Mediaas shown in the screenshot below
- Click the video you want to start with
- Watch the network logs
- You'll see an entry that starts with
playlist(screenshot below)
- Right click it
- Copy the URL
- Paste it after
youtube-dlin a terminal:
amolith@poseidon:~ $ youtube-dl https://video-cdn.linuxacademy.com/vods3/_definst_/smil:box/cdnstore/modules/lots-of-stuff-in-here
- Press enter
- Watch the magic unfold
At a high level, youtube-dl is acting like your browser and following
the m3u playlist to download chunks of the file. After it fetches them
all, it runs them through ffmpeg to stitch them together into a single
video!
I found it useful to open a text editor and script downloading a whole
course at a time. All you have to do is type youtube-dl -o and
copy/paste it however many times there are videos. Then, copy and paste
the video title in quotes after -o and add .mp4 to the end (command
example below). After that, paste the URL. Do that with every video in
the series, save the script, run chmod +x <script>, then ./<script>
and (after a bit) you'll have an entire course you can watch at your
leasure!
amolith@poseidon:~ $ youtube-dl -o "04 - Conclusion and Next Steps.mp4" https://video-cdn.linuxacademy.com/vods3/_definst_/smil:box/cdnstore/modules/lots-of-stuff-here
NOTE: You may want to set up your directory structure beforehand so it's easier to script the process. Here's an example of one of mine:
