Having random crashes when swapping scene.

[Correalian]

Hi, yesterday during my stream I switched to BRB scene and when I came back I found OBS Studio has crashed. I've never encountered this before and will include the logs. Then tonight went to feed my dog, hit BRB and came back and found it had crashed again.

I've not changed anything for months with settings or such. Till the last two days had zero issues.

Any ideas on the cause and what I can try to rectify it?

Can you attach crash reports if there any? (main menu Help > Crash Reports)

 

[Correalian]

Sure, there is just one for the first stream. None for the second time it crashed.

I'm going to test with no plugins and see if it will do it again in the meantime.

No resources left (RAM) for OBS to complete the task.

Hi thanks for the info. I am just curious on why this is happening after not being a issue for months though. Is there a way to automate the ram to be cleared as I thought 64GB + the pagefile was enough for my needs.

Any recommendations?

You may try to look at the Task Manager ( like in this thread: https://obsproject.com/forum/threads/obs-studio-using-too-much-vram.185274/ ) and then make conclusion if something can be simplified.

Normally, the call to "obs.dll!video_frame_init" (allocation of the memory for a new frame) shouldn't result in a error like "obs.dll!os_breakpoint" (breakpoint reached).

Next two strings preset in the both logs:

07:00:40.492: error:   Failed to create D3D11VA video decoder
07:00:40.492: error:   Failed setup for format d3d11: hwaccel initialisation returned error.

these errors are from Media Source or sometimes Video Capture Device source.

In the mentioned thread (see above) browser acceleration was mentioned as a main reason of inadequate VRAM consumption. So, maybe it was the first and the Media Source playback (configured to use hardware acceleration) failed because of this.

Hi, thank you for the link and info, will check it all out tonight. The media source in question is just a short looping video (a few mb) to use on the break message scene using VLC.
