Random Crash When Displaying Image Source - Unhandled exception: c0000005 / Fault address: 7FFF7DB55277

[NMSS_1984]

Hello

I've been having problems since yesterday with a bug that causes OBS to close directly without transmitting or recording, just preparing the window to show what I need. Whether it's an emulator, a game, or anything. Sometimes it closes without further ado, and other times it throws an error message that only says:

"Woops, OBS has crashed!

Would you like to copy the crash log to the clipboard? The crash log will still be saved to:

And here it indicates the path of my computer where the error report is."

I have looked at this report, but I do not understand what has crashed, it only says: Fault address: 7FFF7DB55277 and that Thread 4540: (Crashed) related to the w32-pthreads.dll. But I don't understand what the mistake is here to be able to solve it. It seems strange to me because not less than a week ago everything was working correctly and without errors.

If someone can help me solve it, I would be grateful.

I leave the reports and thank you in advance.

Likely interference from the Source Record plugin's side on object destroy. Please, check the plugin's thread, because some mistakes were fixed in the latest release of the plugin.

Okay, yes. That's the problem. Thanks.
I have installed the new version of the plugin, but now it fails when changing the screen resolution of whatever I set to broadcast to full screen, OBS ends up crashing as well.
I tried a clean install of OBS using only the plugin that's giving me the error, either with the same configuration or another one, and I can't get it to work normally. I don't know what else to do to fix it.

I'm leaving the new log and the crash file in case they're helpful.

These last logs you have posted are not much different from the previous ones. Anyway, I think you should post them in the Source Record discussion thread - there is chance that in this case these issues will be addressed in the next release of the plugin.

Meanwhile, there is alternative named "Branch Output" plugin, and you may try it (of course, do not install both plugins in one portable OBS, create another one portable for your tests):

Branch Output - Streaming/Recording filter for source,scene

Note for MacOS & Linux OBS 31 has crashing issue on SRT failure so we recommend staying OBS 30.2.3 for SRT user. This plugin allows to live stream and/or recording for each source individually. Added “Branch Output” to source or scene effect...

I suspected it, but thanks for taking a look at the logs.
I already put on record what happened in the Source Record discussion, let's see if they fix it soon.
And thank you very much for the alternative, and the advice you have given me. I'll take a look at Branch Output. :)

...it fails when changing the screen resolution...

It seems that there is a related issue on GitHub:

[bug report] OBS crashed since of accessing deleted video_t · Issue #143 · exeldro/obs-source-record

hi, I think the reason is same with obsproject/obs-studio#11686 steps: install obs 31.0.2 and source-record 0.4.5 （I am using WINDOWS PC） run OBS, add display capture source add source-record filte...

github.com

And if you dig into the relevant PRs and commits, you might find out that likely issue wouldn't be fixed until OBS v31.1.x. So, it is better to have workarounds and don't touch something that is surely leading to the crash.
