Bug Report Random Crash while streaming or recording

[LordRayden]

Hey there,
I really love your software and all configurations I made in the past days working out fine. Sadly I encounter a random crash once in a while with OBS showing the "Ooops OBS crashed"-screen. It happens in both situations, while streaming or while recording. Everything is up-to-date, windows updates (Win7 64-Bit), drivers and OBS Studio. I tried both, the 32-bit and the 64-bit OBS Studio client.

Today I streamed for about 3 hours, with no problem at all and then it suddenly crashed again. I would really appreciate your help.

[LordRayden]

Anyone? :*(

 

[Suslik V]

Look in Windows logs. Event Viewer. http://windows.microsoft.com/en-us/windows/open-event-viewer

 

[LordRayden]

Thanks for your answer.
I checked the event log. I made a custom one including all possible entries of any list in the event log around the time 19:53:49. There is no entry right before that. Only one 7 seconds after the crash under System, which says "Windows Error Reporting Service is now running".

 

[Suslik V]

You are checked both - 'System' and 'Application'? (this logs always takes too long to open on my PC, they are very huge).
Anyway, 'ntdll.dll' - it seems to be the part of the Windows OS. One more question: are you using OBS with Browser source included?

 

[LordRayden]

Yeah, I checked both logs. There is no entry around the moment of the crash. The only entry is the one mentioned above.
The first time I got the crash, I did a research what the 'ntdll.dll' is all about. When I saw it is a windows dll I immediately installed all left windows updates, but I didn't fix the problem.
I don't use Browser source. It is an OBS classic plugin, right? I use OBS Studio. Should I try out OBS classic and can I import/export any of my configurations from OBS Studio?

 

[Suslik V]

Doesn't matter. Studio has own Browser plugin (versions with/without browser, if you wish: https://github.com/jp9000/obs-studio/releases).

Meanwhile you can check your system for stability and obs setups for integrity.

 

[LordRayden]

I don't understand what I should try next. I use the version without the browser plugin. Why is this important and should I try the version including the browser plugin?

 

[Suslik V]

Oh, man! Forget about browser plugin. I'm simply asked - you answered.

Make new portable OBS Studio in different folder, make new scene, start recording, loop fr-043 demo and see what could crash first in nearby 4 hours. Then repeat with streaming.
