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>.

Environment and Climate Change

Freezing In Frigid Offices While the Planet Burns

When you’re running a space heater under your desk because the central air is too cold

So many things about trying to reduce our energy consumption are really hard but one thing is really easy: Stop keeping offices at 60 freaking degrees Fahrenheit.

I used to work in a newsroom so cold — in summer — that I kept a space heater going under my desk and frequently wore my winter coat all day.

Meanwhile, the male editor had a small fan blowing against him at all times. He thought the room was sweltering and forbade anyone to touch the thermostat. (When he was fired and I took over, I walked directly to the thermostat and adjusted it to 70 degrees.)

I used to wear light summer dresses that were comfortable to walk to work in and then I’d enter the meat locker of an office and have to put on outerwear. That’s insane.

It’s a common complaint that women are always cold and men are always hot. It’s a stereotype, but true in my experience.

It isn’t possible to keep everyone happy in the same environment. So let’s choose an environmentally friendly compromise and keep the rooms a little warmer in summer and a little cooler in winter.

We live in a big old house that’s expensive to heat and cool, so in winter we keep it quite cold and I layer up. If climate change and high utility bills weren’t a consideration, believe me, I’d keep my house toasty warm in winter, but it’s more prudent for the planet and my pocketbook for me to wear sweaters and thick socks instead.

In the summer, we keep the windows open when we can. As I write this, the forecast calls for today to be the first day of the year that will break 90 degrees. (And it was still cold a couple of days ago!)

Old houses with lots of windows and high ceilings do better in hot weather than in cold, so we hold off on closing up the house and using air conditioning until it’s unbearable.

As a side note, when my European husband moved here almost exactly 16 years ago, he scoffed at American air conditioning. “I don’t see why you need it. We don’t use air conditioning in the Netherlands,” he said one day.

Then he experienced Illinois humidity. “Let’s get that air conditioning going!” he said.

(It reminds me of the first time he experienced a Midwestern blizzard. Before he could drive home from work, he had to dig out our little car. Then he got stuck on the way home and had to walk the rest of the way. He announced, “Now I finally understand why you Americans drive those big-ass trucks.” Alas, I only had a Neon, and it took a while before we could afford a second vehicle.)

Everybody’s tolerance for high and low temperatures differs, every region has a different climate and everyone’s housing and work situations are different, so some flexibility is called for. I won’t tell people they shouldn’t use air conditioning at all. Even though I like summer, I hate it when the humidity is so high that my clothes are damp when I’m doing nothing but typing.

But adjusting the temperature in the workplace is an easy thing to change, and it’s even easier now that dress codes are generally relaxed. When people were expected to dress in suits, they needed cooler temperatures. Most office dress codes accept short sleeves now, and that’s a good thing.

No more wastefully frigid offices!
