Describe the issue you are experiencing

I recently moved from some old version of ghcr.io/home-assistant/home-assistant:stable to 2024.11.0, and found that my Generic Camera streams no longer live update.

The static picture that is generated from the stream is correct, and updates at intervals; I can see in the browser tools that the static image endpoint is successfully being polled in support of that.

I was able to open the playlist file in VLC and view footage, so I assume that the m3u8, mp4, and m4s segments are valid. As such, I think this is a frontend error.

Describe the behavior you expected

The live camera streams are viewable
