# Forward
|
||||
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`](https://github.com/ytdl-org/youtube-dl/).
|
||||
|
||||
# Setup
|
||||
* Install [`youtube-dl`](https://ytdl-org.github.io/youtube-dl/download.html)
|
||||
* Make sure you have a browser handy
|
||||
* Create a community account on [Linux Academy](https://linuxacademy.com/join/community)
|
||||
* 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 `Media` as 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-dl` in a terminal:
|
||||
|
||||
```bash
|
||||
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!
|
||||
|
||||
```bash
|
||||
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:

||||
