Abstract

only, some have video only, and some have both video and audio. And also they’re available in multiple formats. For video there is AVC (which is apparently H.254), VP09, and AV01. And for audio there’s Mp4a and Opus. I don’t know what Opus is but apparently it is noticeably better than Mp4a. So if you’ve ever gone to a YouTube download page and seen a million download options that’s why. Although I hide the redundant ones and just display the one with the lowest file size at that quality level (usually VP09 or AV01).</p><p id="b96b">It’s actually pretty cool to see AV01 as I talked about it <a href="https://readmedium.com/why-apple-adding-av1-support-is-a-big-deal-faa46a356f3c">here</a>. And it does compress videos a little better than VP09 and a lot better than AVC.</p><p id="d170">Also apparently YouTube does something called DRC, dynamic range compression (Not Democratic Republic of Congo). It makes the quiet sections louder and the loud sections quieter. Apparently people really hate it and I guess there must be a way to disable it because I have not been able to find a music video with DRC enabled. I’ve never heard anyone talk about this before though.</p><p id="e027">So now that we have the formats we can just download them. Each format has a download link oddly enough. I did not expect that. Just keep in mind that the YouTube download links expire in 6 hours.</p><p id="3fc9">Of course here we run into a problem. When I saw this I was like, “Great, let’s just download an audio-only track if we only want audio or a video+audio track if we want video.”</p> <figure id="dd49"> <div> <div> <img class="ratio" src="http://placehold.it/16x9"> <iframe class="" src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fgiphy.com%2Fembed%2FMvioOPqhOm6b4BI0FQ%2Ftwitter%2Fiframe&amp;display_name=Giphy&amp;url=https%3A%2F%2Fgiphy.com%2Fgifs%2Ffallontonight-jimmy-fallon-tonight-show-MvioOPqhOm6b4BI0FQ&amp;image=https%3A%2F%2Fmedia0.giphy.com%2Fmedia%2Fv1.Y2lkPTc5MGI3NjExa203NTd1dnVhNGpveHByMmxsOGRzZGxsejhsZzh2Zjk5N20xMTYwbSZlcD12MV9pbnRlcm5hbF9naWZfYnlfaWQmY3Q9Zw%2FMvioOPqhOm6b4BI0FQ%2Fgiphy.gif&amp;key=a19fcc184b9711e1b4764040d3dc5c07&amp;type=text%2Fhtml&amp;schema=giphy" allowfullscreen="" frameborder="0" height="435" width="435"> </div> </div> </figure></iframe></div></div></figure><p id="9eda">If you do that you’re restricted to at most 720p 30fps. Or so I’m told. I haven’t been able to find a file with both video and audio over 360p. And some videos don’t have any video+audio tracks at all. So that means we’re going to have to download a video file and an audio file (preferably without DRC) and merge them together.</p><p id="e01b">And this is perhaps the first really big problem I ran into. If I was doing this locally it would not be that big of a problem because there’s a nice command line package called <code>FFmpeg</code> that will just do it for you. Unfortunately it’s a bit more complicated when you’re working with Node.js because you have to do a bunch of file manipulation stuff.</p><p id="12d8">I ended up deciding to just download the files from Google’s servers separately and then merge them locally. Apparently Flutter has a package called <code>FFmpeg-kit</code> that will do this. Unfortunately it only works on Android, iOS, and MacOS.</p><p id="fdbf">Although Android will not be getting YouTube downloading because Google is really strict about that.</p> <figure id="eaa2"> <div> <div> <img class="ratio" src="http://placehold.it/16x9"> <iframe class="" src="https://cdn.embedly.com/widgets/media.html?type=text%2Fhtml&amp;key=a19fcc184b9711e1b4764040d3dc5c07&amp;schema=twitter&amp;url=https%3A//twitter.com/EzraDuown/status/1776352074449530961/&amp;image=" a

So that means that the only platform able to benefit from YouTube downloading is iOS. There is no macOS version of the app but you can run the iOS app on an Apple Silicon Mac. Web users will be restricted to downloading audio or downloading 360p videos. Oh well. Maybe I’ll improve this feature in the future.</p><p id="cae5">And another problem. YouTube throttles some of the downloads. Not all of them though which is weird. I thought it was broken at first. Nope, it’s just that the downloads were really really slow.</p><p id="74fe">Although there’s a way around this too. Flutter has its own package for downloading YouTube videos called <code>youtube_explode_dart</code> and this one has gotten around the throttling issues. It’s listed as issue #180 and fixed in pull request 185.</p><figure id="c76e"><img src="https://cdn-images-1.readmedium.com/v2/resize:fit:800/1*R0QbSVVKcpNt1NDnlL-7Qg.png"><figcaption></figcaption></figure><p id="4a2c">And it works great now. Well, for the streams it supports. It doesn’t support all the streams. But it supports enough.</p><p id="7308">And, one more thing <code>youtube_explode_dart</code> doesn’t actually do everything <code>youtube-dl</code> does. <code>youtube-dl</code> actually gives you a lot more information on the actual files (such as if the audio is DRCed). So I’m still going to have to use it. But I can use <code>youtube_explode_dart</code> to actually download the files.</p><p id="8fe6">I do feel a little silly for wasting so much time on this feature. Like, I built an RSS reader to watch YouTube videos, not to download them. And the only people that can really take advantage of this feature are iOS users.</p><p id="9388">It’s funny. Everyone thinks iOS is the locked-down one. But in this one specific case Android is more locked down. Because if you look up YouTube downloaders on iOS there are pages and pages of them.</p><p id="0e6e">I could see myself taking advantage of this feature. Stratum 3.0.0 also introduces the ability to add external links. So I could find a YouTube video I like that I want to download and I could just download it.</p><p id="01c9">And this experience has taught me a lot about the inner workings of YouTube. Mostly the subtitles. I had no idea the method I was using to get subtitles before was so suboptimal. It works and there’s nothing wrong with it but it could be better.</p><p id="7e7d">I’m pretty happy with Stratum’s YouTube functionality now. I was happy with it before, to be honest, I just went down a ‘YouTube Rabbit Hole’. But I did have one more feature planned: automatic YouTube summary generation.</p><p id="5b0e">Because since adding YouTube summaries I’ve been watching a lot more YouTube. I mean summarizing a lot more YouTube. There are a lot of channels I’m interested in but can’t get to due to time restrictions. Like TED and DW News. Guess what? I follow both of those sources of news now and just read the summaries. But you know what I don’t like? Tapping on the button to generate the summaries.</p><p id="8a38">Well, those are some future plans. It will be expensive though, which is also why I’m planning to announce new pricing for Stratum soon.</p><p id="f6db">If you liked this post and would like to stay updated with my future articles consider using my RSS app Stratum on <a href="https://apple.co/3rZyh9B">iOS</a> and <a href="https://play.google.com/store/apps/details?id=com.amorfatite.keystone">Android</a>.

Invitation to Published Authors

How Writers and Bloggers Can Benefit from ILLUMINATION Book Chapters.

A publication giving voice to published authors on Medium

image designed by Dr Mehmet Yildizdigitalmehmet.com

ILLUMINATION is now older than three years, established on 19 March 2020, and proudly shining with many achievements.

Leveraging our past success and capabilities, now it is time to create a new initiative aiming to give voice to many published authors and create a path for aspiring writers to become published authors.

The primary goal of ILLUMINATION Book Chapters is to allow published authors to repurpose their published content and present them to a new audience.

While gaining new followers and fans, published authors can get an opportunity to monetize their existing content on Medium within copyright rules and Medium’s publishing policies.

Content is the king of the 21st century. Re-purposing is science but not rocket science. Writers, with a bit of effort, can repurpose their content. We will guide you and promote your content meaningfully.

Format and delivery methods may change, but books never die.

The ILLUMINATION Book Chapters publication is designed as a tool to empower published authors by increasing the chance of gaining new followers and fans of their content.

What can you publish on ILLUMINATION Book Chapters?

Initially, three types of submissions are encouraged for this publication. After the pilot phase, we will re-evaluate and may extend our scope.

1 — Published books

As obvious, you can publish your book chapters in story formats. Several authors like Casi Mclean, Shashi Sastry, Claudia Stack have already published chapters of their books on ILLUMINATION and ILLUMINATION-Curated.

You can transfer your previously published chapters from ILLUMINATION and ILLUMINATION-Curated to ILLUMINATION Book Chapters. This transfer can expose your stories to a new audience who loves reading book chapters in story format.

A book chapter in story format can usually be around 5 to 10 minutes of reading time. If your chapters are longer than this, you may create sub-chapters like Chapter 1a, Chapter 1b, Chapter 1c, etc.

2 — Book reviews

Book reviews can be informative to readers.

You can also publish reviews of the books and books that you enjoyed reading and found valuable.

As a sample, I published a self-review of one of my books today.

3 — Author Testimonials

Testimonials are critical to the success of published authors.

You can publish stories, including testimonials about your books.

In addition, you can write stories about the book chapters that you read from other writers in testimonial format.

Based on feedback from many subscribers, we identified the need for book chapters. Considering the number of contributing writers for the ILLUMINATION family of publications, we believe many published authors can benefit from this unique service.

For example, during writer interviews and chats on Medium, I came across books by Phil Truman, Britni Pepper, John Cousins, John Cunningham, René Junge, Martine Weber, Liam Ireland, Jeff Hanlon, Henery X, Helen Cassidy Page, Melinda Blau, Karen Madej, Annelise Lords, Sharon Hurley Hall, Christopher D. Connors, Earnest Painter, Agnes Laurens, Tim Denning, Casey Botticello, Selma, Terry Trueman, Robert Trakofler and many more.

There is no genre constraint for your submissions. You can submit fiction, non-fiction, and poetry. The only exception is erotic content which could perform better in other specialized publications on Medium.

You can also submit chapters of unpublished manuscripts.

Our secondary purpose is to create a path for our writers to transform into published authors. Thus, this publication can be a stepping stone to preparing your manuscript, using feedback from beta readers, for publishing opportunities.

Submission Guidelines

You need to own the copyright of the book chapters that you publish in this publication. A clear copyright ownership statement must be provided.

Readers of this publication expect high-quality content. Therefore, all stories must be proofread and edited.

Please use this checklist before submitting your stories.

You can add a link to the original version of your book.

You can also add your writer profile and a link to your website.
