Autoplay only the first youtube video when multiple tabs have been opened

[ShanaryS]

⚬ PROBLEM:

When opening multiple youtube videos, they all start playing if autoplay is enabled. This gets solved if I disable autoplay in the extension, but then when opening and watching a single youtube video, it doesn't autoplay.

⚬ SOLUTION:

Add an option to only autoplay a video if only a single youtube.com tab is open. This allows autoplay in the normal case while also preventing many videos being played at once.

⚬ ALTERNATIVES:

There are none. The extension allows pausing when switching tabs, but that prevents having youtube play in the background.

⚬ RELEVANCE / SCOPE:

Absolutely should be the default. I imagine the main reason for preventing autoplay is to stop when opening multiple tabs, at least for me.

⚬ "SIDE EFFECTS":

Would change the autoplay option from a boolean to three choices.

⚬ CONTEXT:

hi! @ShanaryS alternatively / additionally our feature "only one player instance playing" autopauses what plays in the once you play (or autoplay) in an another tab.

@ImprovedTube This has a better experience with multiple tabs but not quite what I wanted. I would prefer the option to keep playing the original video and prevent autoplay on the rest. Currently the active tab takes over.

I would also like if all it did was disable autoplay if a video was already playing. This allows you the option to manually play a second video without stopping the first if desired.

i think you want a proper/fixed "only one player instance is playing" ( https://github.com/code-for-charity/ImprovedTube-for-YouTube/issues/1516

plus maybe the autoplay options:

• autoplay: on for the first video only.
  • autoplay only for the first video but overwriting blocked autoplay by the browser. Like an audio-only-/podcast-mode.
    • ultimately this brings up the question: "What if you close the background tab playing, and opened more youtube tabs still blocked: shall, the oldest be played next, or the most recently added. And why would we use the tab bar like an unfomfortable queue / playlist?"
    • in terms of queue/history/playlists/bookmarks, we'd better start here? Playlist / watchlist generator from open tabs, browsing history, etc.  #1546
