OBS Crashing, Bit Rate Going Down to 0

[Mark S.]

Hello,

The title says it all. OBS has been crashing numerous times as of late and I'm just... tired of it.

I've looked all over the forum to potentially solve the problem on my own, but I can't seem to identify exactly what the issue is. I checked my Windows Firewall settings but my Firewall doesn't even register OBS as an app, even though the software is installed, so I have no way to permit it through, but not even sure if that's the problem but may be it.

It could also be Internet fluctuations, which are a tad bit of a problem too, but I just don't see how OBS crashing could be cause by Internet lack of stability when the Internet itself works fine during the OBS crash.

I've also updated my Nvidia Drivers just in case, but have no idea if that was the solution and if it changed anything.

I'm hoping someone knowledgeable enough could provide some support after taking a look at my logs. I would be most thankful!

is this intentional?

11:48:31.927: Warning: OBS is already running!​

11:48:31.927: User is now running multiple instances of OBS!​

did you reboot after the crash? or check running processes and kill any zombie ones?

you have an old CPU for real-time video encoding. 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

Looks like you are trying 60fps, and using color correction on the webcam, right? on a 7 generation old CPU with only 12GB RAM, and using browser sources?? I'm sure those who know more than I will tell you it can work, but I'd suspect some optimizations at both OS and OBS levels

Your log indicates items in your plug-in folder that aren't plugins. Time for some clean-up?

Have you researched this?

hopefully you've seen the threads indicating streaming often requires CBR, but that you DON'T want to use CBR for recording

Thanks for responding!

This is not intentional. Whenever OBS crashes, it thinks there is already an OBS window open after the program appears to be fully shut down. Whenever I start it up, it thinks there's another OBS Window open where there isn't.

I've monitored all mid-stream and nothing seems to hit a cap. The memory stay at 63% usage exactly, never lower, never more. Not sure if that's a bottle neck situation there.

Not sure what could be in the plugin folder, wouldn't even know where to access it. It is as simple as finding the folder under the OBS program and delete all plugins?

I do use CBR for both stream and recording which I do simultaneously. Makes things much easier for me as I need both footage and to stream for future purposes. It'd be a first for me to be told CBR is bad for recording, so might need to look into that more. I always thought CBR was standard TBH.

This represents a fundamental mis-understanding of how the operating system (Windows) works. There IS an instance of OBS running (or crashed and not closed), even if you can't see it. Basic computer operations
You need to learn how to fix this ... (Task Manager and End Task/Process, log off/on, or reboot... depends on your level of understanding how far you can get with each)

are you monitoring CPU & GPU usage, Disk I/O, disk latency, etc?

Here's the quick-start guide:

OBS Studio Quickstart

Yes do look up CBR recommendations for streaming, vs CPQ for recording
see https://obsproject.com/forum/threads/best-settings.140188/#post-514693 @FerretBomb comment #2 [and plenty of other threads if you look]
not comment in log about disabling PVT

basically I recommend researching running OBS on and under powered computer. And if you are recording, using a SSD (vs a HDD) may (probably will) help overall (but whether worth adding to such an old computer is a separate discussion. I would but I know how to handle duplicating a boot drive, installing multiple disk drives, dealing with drive partitions, data drive (D:) etc... some may find all that overwhelming
