greetings from a fellow church livestreamer
There can be lots of possibilities
- is OBS indicating RED for dropped frames (a network issue)
- Are you recording and streaming simultaneously (I do, so I have a higher res 1080p recording vs the very highly compressed FB version in their library)? if yes to recording, is the recording ok?
- are you monitoring hardware resource (CPU, GPU, RAM, etc) utilization [for ex. using Task manager’s Performance tab and/or Resource Monitor] to see if your system is being maxed out with your settings?
real-time video encoding is VERY computationally demanding
And then there is the basics? what have you changed (sometimes hard to know if you don't follow good change mgmt practices)
Hopefully no one got silly and decided to up to 60fps?
You should have OS updates, and possibly security software? any OBS 3rd party plug-ins recently added/changed?
Anyone forget to to turn off (or recently enable) unnecessary and inappropriate background processes during livestreaming like OneDrive, Google Drive, etc.
Or maybe folks back in person, and Internet bandwidth is no longer dedicated to streaming? Or someone left an office computer on and its using bandwidth, etc? Or worse, you are using WiFi, and running into WiFi contention (which is most of the time, but unless you know what you are doing, most folks don't notice it... but you will with streaming)
Many of the above won't be in an OBS log. But if you want folks to review yours, per the pinned post in this support forum
OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...
