Describe the issue you are experiencing

The video player for live camera streams often falls behind if there is an interruption to video playback. Interruption to video playback can include (but not limited to):

network issues
switching to another tab and HA losing priority (Web browsers)
switching to another app and HA losing priority (mobile apps)

Describe the behavior you expected

Video players should detect and automatically correct when they are lagging behind more than expected.

Steps to reproduce the issue

Add picture entity card to any dashboard pointing to a camera with a live video stream, ideally one with a timestamp for comparison
Load the dashboard and watch the video stream for a few seconds. Note how many seconds the stream is behind
(on Web) Switch to another tab and then go to another application. (on mobile) Switch to another app.
Wait about 30 seconds
Go back to HA dashboard, camera should resume where it was when it was suspended/de-prioritized because it was put in the background.

Additional information

This has been a long-standing Home Assistant frontend issue. The video player is not able to self-heal and realize when it has fallen behind in playback. This is often reported as video delay, but this is not related to the HLS video delay issue that causes a 15-30 second video delay. You can easily reproducible it with a LL-HLS setup that starts with an initial 1-2 second video delay that can easily become 30 seconds or even a few minutes.

The only way to "solve" the delay is to reload the page. Which for mobile apps is not really possible. The video player itself should be able to auto-correct these delays.
