How to get python to download YouTube videos in the background?

[Pythenx]

I am looking to create a small project. The idea is that you input a youtube video link and it downloads it onto your computer. I was thinking about using Selenium - it opens the browser, goes to MP3 video converter and pastes the link, downloads it. But is there a way of doing it without any visible actions (opening the browser). In other words how can I hide that the browser has opened. It would just open the py program, you input the link and after a while the video has been downloaded.

There are several packages that download youtube, see: https://pypi.org/search/?q=youtube

youtube-dl is big Python project with 48,454 stars on GitHub.
Can be used in many ways command-line,GUI or web-app.
I made solution's that to use myself with Flask,to get MP3 from a youtube link where youtube-dl dos the background work.

im not sure if this is still accurate in the process, but if so you can replicate it in python.

Hmm why try an old method that for sure will not work now,youtube-dl is always updated as a lot people work on it.
Also support a lot of other video sites youtube-dl supported sites.

Basic usage is simple youtube-dl url_link
Example get video:

λ youtube-dl https://www.youtube.com/watch?v=d8OI9FllKfg
[youtube] d8OI9FllKfg: Downloading webpage
[youtube] d8OI9FllKfg: Downloading video info webpage
[youtube] d8OI9FllKfg: Downloading js player vflGPko2h
[download] Destination: Komodo - (I Just) Died In Your Arms-d8OI9FllKfg.f248.webm
[download] 100% of 30.32MiB in 00:16
[download] Destination: Komodo - (I Just) Died In Your Arms-d8OI9FllKfg.f251.webm
[download] 100% of 4.14MiB in 00:02
[ffmpeg] Merging formats into "Komodo - (I Just) Died In Your Arms-d8OI9FllKfg.webm"
Deleting original file Komodo - (I Just) Died In Your Arms-d8OI9FllKfg.f248.webm (pass -k to keep)
Deleting original file Komodo - (I Just) Died In Your Arms-d8OI9FllKfg.f251.webm (pass -k to keep

Example get MP3 in highest quality:

λ youtube-dl --extract-audio --audio-format mp3 --audio-quality 0 https://www.youtube.com/watch?v=d8OI9FllKfg
[youtube] d8OI9FllKfg: Downloading webpage
[youtube] d8OI9FllKfg: Downloading video info webpage
[youtube] d8OI9FllKfg: Downloading js player vflGPko2h
[download] Destination: Komodo - (I Just) Died In Your Arms-d8OI9FllKfg.webm
[download] 100% of 4.14MiB in 00:02
[ffmpeg] Destination: Komodo - (I Just) Died In Your Arms-d8OI9FllKfg.mp3

I use youtube-dl also. The problem is they do not support all sites. youtube-dl doesnt even support sites like.... speedvid.net, vidlox.tv, vidoza.net, clipwatching.com, vidtodo.com, etc. And some of the sits they do say they support, often have trouble working. The other problem with youtube is if they think you are pirating they wont answer your issue and just not give you helpful info. They wont help if they know the site is pirating, but they have how many sites listed as supported? The only alternative is to build your own. I have thought about this, but not had the desire to devote the time to do it.

Plus if the concept is to create your own method of downloading, using youtube-dl is not a fix. It does not teach you how to download from different sites via programming.

But is there a way of doing it without any visible actions (opening the browser).

Yes there is a way to hide the browser. You can use it in headless mode by giving it the argument --headless

options.add_argument("--headless")

Beside question. Is it possible to create a Python code like the one below written in PHP? Several quality options are selectable, as shown here http://imgbox.com/YciMpWyC

Output:

Thanks, and cheers
