Just upgraded and now OBS Studio keeps crashing...

[BloodEagle]

With an encoding error. I have tried switching encoding types and a few other things with 0 success. I thought because of this it was Nvidia Broadcaster so I switched to Xsplit Vcam and it also crashed....

There was more thread stuff but it made me cut it off.

The problem is nvidia broadcast itself

 

[BloodEagle]

Why would it also crash not using Nvidia Broadcast but instead using only Xsplit Vcam?

 

[Harold]

If the crash happens in the same thread with only xsplit vcam, then it's still nvidia broadcast

Have you tried temporarily removing nvidia broadcast?

 

[BloodEagle]

You mean uninstalling it? That will be my next step as I have an esports broadcast to do tomorrow and cannot have my stream shut down in the middle.

Thanks for the advice by the way.

 

[Harold]

The crash report you provided above says the crash is entirely in the nvidia broadcast components.
If you have similar modules listed in the crashing thread regardless of using nvidia broadcast or xsplit vcam, then it's still the nvidia broadcast causing the crash.

 

[BloodEagle]

Ok, so an update on this thread....

Over the past few days I have uninstalled, reformatted, and reinstalled Windows 10 because even though I had uninstalled Nvidia Broadcast it kept showing up on my system.

After wiping and reinstalling, resetting everything up, and attempting to stream today, I ended up getting the exact same OBS encoding crash as well as Star Citizen crashing. All of this happened this time without broadcast being installed.

I have included the log file in the hopes that someone can help me...

From the log:

08:47:26.171: Device Remove/Reset! Rebuilding all assets...

This is a graphics driver crash. Lost communication between your GPU and the graphics driver. This is either a bug in the graphics driver (update to the most recent version or to some older version that is known to work) or a hardware issue with your graphics card, for example incompatibility with your mainboard or insufficient power supply.

 

[BloodEagle]

Thanks. Power Supply is 1200 watt running a 3090, Ryzen 9 5950Xn and 64G of ram on a Gigabyte Aorus Master MB. All drivers are at their newest, BIOS fully updated and Brand new windows 10 install on a reformatted SSD.

I will try rolling back the GPU drivers 2 versions and see if it still happens.

 

[koala]

With "power supply" is also meant that you should verify all extra power connectors to your GPU have proper cabling according to the instructions in the manual, and they use different outlets of your power supply device. The RTX 3090 is quite a power hog under load.
Also make sure there is no overheating. And while you're at it, conduct a memory test and make sure your RAM is ok.

Did exactly this hardware work before? Or is it new and never worked with this workload properly before? If it never worked before, it's some hardware issue you have to find - you cannot fix hardware issues with any software installation or configuration.

 

[BloodEagle]

The MB, CPU, and RAM is all brand new. The 3090 is using a separate feed for each of the 3 power cables.Ran a memory test and showed no issues, but you know how that stuff can be. Everything worked fine in the past and this the first time I have had these issues.

I "think" I may know what the issue is... Doing some testing I noticed this only seems to happen with Nvidia Broadcast and XSplit Vcam which both create a virtual camera which seems to be what is making stuff crash. When I use ONLY my cam there does not seem to be any crashes.

I noticed that the next version of OBS includes these fixes..

Perhaps in the end these are indeed my issues and it will be fixed when the next version pops.

Not sure if it is stable enough for me to start using now or not.

 

[R1CH]

Those are niche crash fixes that won't help your issue. " Device Remove/Reset! Rebuilding all assets... " is really bad, basically your GPU crashed and had to be reset, usually crashing any apps along the way. Might be a faulty GPU or motherboard or something, usually hardware related.

 

[BloodEagle]

Thank you for letting me know. Whatever this issue is it has crippled me right in the middle of a very serious streaming week.
