<p>With the advent of <a href="https://www.spotify.com/">Spotify</a>,
<a href="https://www.apple.com/music">Apple Music</a>, <a href="https://youtube.com">Youtube</a>,
<a href="https://www.pandora.com">Pandora</a> and many other streaming music services, the
need to have local mp3 files doesn't crop up very often. However, my kids either
have cheap mp3 players or use their
<a href="https://en.wikipedia.org/wiki/Nintendo_3DS">3ds's</a> to play local mp3 files.</p>
<hr />
<p>This post is a quick tip on ripping an album from youtube using a web browser and
a few cli apps. Remember, most tasks don't need a bloated gui to be done
efficiently.</p>
<h3 id="requirement">Requirement</h3>
<ol>
<li>A Web browser that can play youtube videos</li>
<li><a href="http://rg3.github.io/youtube-dl/">Youtube-dl</a></li>
<li>ffmpeg</li>
<li>Bash</li>
</ol>
<h3 id="prep-work">Prep work</h3>
<h4 id="install-ffmpeg">Install ffmpeg</h4>
<p>Ubuntu</p>
<pre><code>sudo apt-get install ffmpeg -y
</code></pre>
<p>Fedora</p>
<pre><code>sudo yum install ffmpeg
</code></pre>
<p>Gentoo</p>
<pre><code>sudo emerge ffmpeg
</code></pre>
<h4 id="install-youtube-dl">Install Youtube-DL</h4>
<p>If your on a Debian or Ubuntu flavor of linux</p>
<pre><code>sudo apt-get install youtube-dl -y
</code></pre>
<p>Fedora</p>
<pre><code>sudo yum install youtub-dl
</code></pre>
<p>On my favourite, Gentoo</p>
<pre><code>emerge --ask youtube-dl
</code></pre>
<h3 id="download-the-album">Download the album</h3>
<p>At this point you have all the tools you need to get the job done. Have a browse
around on youtube to find the album you want an offline copy of and copy the url of the page. Then from a
command prompt:</p>
<pre><code>mkdir ~/tmp
cd ~/tmp
youtube-dl -x --audio-format mp3 https://youtube.com/fullurltovideo
</code></pre>
<h3 id="create-a-list-file">Create a list file</h3>
<p>While the audio file is downloading, your going to want to create a simple txt
file which lists the tracks, titles and start and end timings. I simply fast
forwarded through each track toward the end of the song and made note of the
mintes and seconds. I created a file with each line representing a track in the album with the following details:</p>
<p><em>Track Number</em>-<em>Track title</em>-<em>Start duration</em>-<em>End duration</em></p>
<p>The durations are in the form of HH:MM:SS. Here is what my file looks like:</p>
<pre><code>cat ~/tmp/list.txt
01-The Greatest Show-00:0:00-5:08
02-A Million Dreams-00:5:08-9:38
03-A Million Dreams Reprise-00:9:39-10:38
04-Come Alive-00:10:38-14:25
05-The Other Side-00:14:25-17:58
06-Never Enough-00:17:58-21:28
07-This Is Me-00:21:38-25:23
08-Rewrite the Stars-00:25:23-28:59
09-Tightrope-00:28:59-32:50
10-Never Enough (Reprise)-00:32:50-34:14
11-From Now On-00:34:14-40:12
</code></pre>
<h3 id="split-the-audio-to-seperate-mp3s">Split the audio to seperate mp3's</h3>
<p>Now that my file has finished downloading, I can convert the file into separate
song files</p>
<p>Here is the little bash script I wrote to split the file based on the contents
of the list.txt file</p>
<p><em>Note the <code>-nostdin</code> parameter below is required to prevent ffmpeg from
consuming bytes from input which makes it go screwy</em></p>
<pre><code>cat splitsong.sh
#!/bin/bash
while IFS=- read tr ti s e; do
FILENAME=&quot;${tr} - The Greatest Showman - ${ti}.mp3&quot;
ffmpeg -nostdin \
-i &quot;$2&quot; -acodec copy \
-ss &quot;$s&quot; -to &quot;$e&quot; \
&quot;${FILENAME}&quot; &lt; /dev/null
done &lt;&quot;$1&quot;
</code></pre>
<p>I then execute the file like this:</p>
<pre><code>chmod +x splitsong.sh
./splitsong.sh list.txt 'Some Sound Track List-qDZLSHY1ims.mp3'
</code></pre>
<p>And the whole thing is over in a matter of seconds.</p>
