The behavior described is initiated by Android, not HLS.js. If you want to pause the media element used by HLS.js when the tab is backgrounded, pause it on visibilitychange. If you want this behavior fixed on Android, please report a bug to Google. |

@robwalch this very well could be an Android/Chrome bug but the issue is slightly different than what you stated: I play an HLS audio stream in Chrome. I then switch to YouTube (for example) – the Chrome audio is still playing which is what I would expect. I play a video in YouTube. The HLS stream from Chrome stops playing as expected and the YouTube video plays as expected. However, after a few seconds the YouTube video pauses on its own with no interaction and then nothing is playing. |

Confirming this is an issue with YouTube playback that you think is related to network activity from a live stream being refreshed in Chrome on Android from a background tab that has not been suspended? If you want to stop network activity from HLS.js, call stopLoad(). This could be done when playback is paused and the page is not visible - the responsibility for this falls on the app using HLS.js. As for that having anything to do with YouTube playback, that is something YouTube and Android teams should look into. |
What version of Hls.js are you using?
v1.5.7
What browser (including version) are you using?
Chrome 122.0.6261.91
What OS (including version) are you using?

Steps to reproduce
Expected behaviour
The YouTube video should continue playing
What actually happened?
The YouTube video is paused for no apparent reason after a few seconds.
It seems like the player in the backgrounded Chrome is still trying to load stream fragments or something after switching from Chrome to YouTube.
