Video.js: Live ui HLS stream crashes in chrome when running in the background

[nathanjamal]

Description

Leaving the player running a live HLS stream (with liveUI enabled) in Chrome in a tab that is not the currently focused tab, causes the page to crash after about an hour. The javascript memory used in this time increases by over 400%. This doesn't seem to happen when the tab is focused.
This can be seen using the LiveUI sandbox test in the Video.js git repo.

Steps to reproduce

1. clone the repository, and move into that directory
2. run npm install or npm ci to install all necessary packages
3. run npm start to start the local server
4. open http://localhost:9999/sandbox/liveui.html in Chrome
5. remove focus from that tab, either by minimising the window or opening another tab
6. after 1 hour open/focus the LiveUI tab

Results

Expected

Page is responsive and has continued playing

Actual

Presented with Chrome's 'Page Unresponsive' modal. Unable to use the page.

Having same issue (v7.5.5), can confirm.

After looking into the issue, this is definitely a duplicate of https://github.com/videojs/video.js/issues/5937

PR https://github.com/videojs/video.js/pull/6621 will resolve this as well.

@matbcvo try upgrading to 7.6.6 (but not to 7.7.x as there was a regression) for the time being

[DispatchCommit]

@gkatsev the RAF fix for #5937 slated for the 7.9.0 should close this issue as well.

[gkatsev]

Video.js 7.9.0 is out as a pre-release, closing as fixed.
