I wonder how the whole thing works when I open a youtube video from a preview inside a chat application on my mobile phone. It looks like the video loads and starts playing in some kind of in-app browser, but there is just full-screen video and nothing else. I also never faced any ads in this "mode" of playing a video, yet recently some strange things started happening where the playback would start together with an…

Not sure what you’re asking. You can get fullscreen video in a desktop browser by pressing F or clicking the fullscreen icon (broken rectangle) below the video. You can get ad-free playback by paying for Premium or sometimes with an ad blocker. Outside the browser, you can get both with yt-dlp, which also integrates into video players like mpv.

From https://github.com/yt-dlp/yt-dlp/wiki/EJS it looks like deno is recommended for these reasons: > Notes > * Code is run with restricted permissions (e.g, no file system or network access) > * Supports downloading EJS script dependencies from npm (--remote-components ejs:npm).

It's fine for this project since google is probably not in the business of triggering exploits in yt-dlp users but please do not use deno sandboxing as a your main security measure to execute untrusted code . Runtime-level sandboxing is always very weak. Relying on OS-level sandboxing or VMs (firecracker & co) is the right way for this.

I use YouTube on a daily basis. I haven't seen any of these problems.

It is likely you use Chrome or a browser that uses Blink for its engine and the OP uses a non-blink browser like Firefox. I use Firefox and I can cofirm since the last few months Youtube usability borders on usable

long press -> save image/video is perfectly supported on a phone, it's just content diffusion platform that arbitrarily restrict it.

No, it's also iOS that's arbitrarily restricting it. I opened a bare .webm directly in Safari and got nothing on long press and nothing in any of the control widgets to save it.

I have an e-ink photo frame on the wall that switches picture once every 24h, picking one of my pictures of the last 10+ years by random. So every single one of my tens of thousands of pictures gets a real chance to be seen at least once during my lifetime :)

Which frame do you use? I’ve been looking for this for a long time, but I wasn’t aware color e-ink was good enough for this yet.
