Question / Help OBS Studio UI freezes

[Asulamur]

So, I'm have an interesting issue where the entire OBS ui will periodically freeze for 5-20 seconds at a time. Sometimes it's just the UI, sometimes it's the cameras as well. It doesn't seem to affect the actual output to twitch, though, but it makes changing scenes and the like incredibly frustrating.

I have attached a crash log, although it typically doesn't actually crash. I can do an entire 2 hour + stream with it behaving this way, but no crash til I shut down OBS.

Any help would be greatly appreciated.

Oh, CPU/MEMORY usage stays low during all of this. I don't get it

If it does this without crashing over an entire output session, we need to see the log of an output session with that happening, not a crashlog.

Please post a log with your issue! Here's how...

When you say "CPU/memory usage stays low", are you basing this from Task manager? What is the actual total CPU usage for your system?

I have attached tonight's log file.

When I say CPU/memory stays low I mean both observed from monitoring task manager and from the CPU usage display native in OBS itself. Total for this system is around 24-35% during stream

When was the last time you updated the bios? Not sure if this would be related in this situation, but the microcode does need constant updating on AMD for stability purposes.

That said, there's only a few things that stand out to me. You've got 5 webcams connected, correct? How are all these hooked up to your system? Any hubs involved, usb extenders? Are they all on dedicated host controllers, as shown by USBView? There could be some kind of connection dropout happening, either through a possible bandwidth limitation or poor connection, which might be causing weird side effects.

The only other thing that really stands out is the use of opencl for your x264 encoder custom settings. I'd try taking this off, just to eliminate any extra variables.

So, I do have 5 cameras setup and try to keep them distributed across different hubs and one camera is connected to a capture card via HDMI. Sometimes there are issues with it not detecting a camera, possibly due to USB extensions, but regarding the problem experienced above.. it seems to be exclusive to OBS Studio. SLOBS is running the same scenes just fine, but is not ideal since it doesn't offer the same functionality with regard to advanced scene switching and scripts to auto change scenes. Also, changing encoder settings didn't seem to help, nor did disabling cameras when not in use.

I haven't tried OBS classic yet, but plan to see if that resolves any issues this weekend.
