[Bug]: Snapshot updates problem
### What happened?

Hi, after 2.0 update I've started to notice that there is a problem with catching snapshots. It works like 1 out 5 times. And if it was not updated it breaks the whole flow and stream becomes unresponsive. Attached some log snippet. I also have all the options active in my Indoor 2K camera config (Unbridge Camera, Force Refresh Snapshot, Improve livestream caching, Use RTSP). Thx in advance.
