OBS was stable. Now crashing.

[dbbriggs5]

Hi all, thanks for any help you can give. Was previously using the latest 29.x.x build on a Mac M1 Mini w/ 8gb RAM. It began to crash randomly in the middle of recording. My setup is pretty simple, only 2-3 filters on a couple of cameras (see screenshots). I tried updating to v30 and also installed the new Advanced Scene Switcher. Same issue. The crash report below is duplicated 5 times from a single recording session, so I'm only sending one (same Crashed Thread, Termination Reason, etc).

I tried to post the whole crash report and it said it was too long so I posted through Thread 12

Meant to say, was previously using the latest 29.x.x build for many months...STABLE...on a Mac M1 Mini w/ 8gb RAM. Anyone got some insight?

 

[jet7]

Yes,

v30.0 in unstable on (M1) Mac. Usually Crashing on Exit.

Older versions like 29 did sometimes hang on exit, but eventually closed without chrashing.

v30.0 seems also have problems with NDI

OBS 30.0 frame rate drop after 27 switch between sources!!

At least on Mac book Air (M1) and with NDI sources this frame drop starts to happen in OBS 30.0 after 27 switch between 2 NDI source. After this frame rate degration start to happen it only get worse and worse after each switch between sources.

Can anyone help me interpret the crash log or give guidance? V29.x was stable for many months, with no changes to any plugins or updates to system software, and no new equipment added, but then randomly started crashing. When I upgraded to V30, it crashes in similar fashion. My log file is in the original post.

 

[mattytwoshoes]

Chiming in here. Updated to v30.0.2 as I started to get "random" crashes on v30.0.0 as well, after months of being stable. I attached the full system crash log here, there is definitely something up with some kind of browser source conflict I think. OBS log files don't show anything weird through the log analyzer...
