The "Enhancer for YouTube" webextension add-on¹ has a "Pause videos playing in background tabs when a video starts playing in the foreground tab" setting that makes a lot of sense: if you already have a playing video+audio tab (ex: a YouTube video), if you start another such tab, it automatically pauses playback in the other tab where sound was playing.

I think that's brilliant both for performance, lower power consumption, and for convenience: after all, it is unlikely that you can watch and listen to two videos at the same time _with sound_ ...

The exception I see is WebRTC: you should obviously not stop a WebRTC video+audio stream in favor of some random video from another tab, in that case it makes sense to have both playing at the same time.

change from safari to another app which is playing sounds, <audio> status on safari will be paused first and then be playiny, but can't play sounds on safari. This is puzzling.

This specific bug is not about Safari.

The problem here is that a different tab means different webview, hence possibly different WebProcess. So this would be a significant effort, and I'm not even sure it would be much GStreamer-related, so I'll update the bug title.
