Steps to Reproduce

Launch OBS 26.1.2.

Additional information

I had updated OBS from 26.1.0 to 26.1.2 and installed the new DAL binary shipped with the new release.
The previous version loads without any problems (26.1.0) when this happened.
I do not have any audio monitoring enabled, nor browser sources.

wookayin commented 3 years ago

Looking at stacktrace, it was crashing while initializing DAL plugins -- the OBS virtualcam itself. (I had installed a new one after the 26.1.2 upgrade). Removing the DAL plugin and OBS can now start without any crashes. Not sure why this happened.

asher-the-thrasher commented 3 years ago

that is the mac virtual plugin crash, Please try removing the virtual cam plugin like described here

https://github.com/johnboiles/obs-mac-virtualcam#uninstalling .

next time check on discord for support first

wookayin commented 3 years ago

@asher-the-thrasher Thanks. I checked discord before writing this but I believe this is a different, new issue. I'd like to note that the DAL plugin that was causing the problem was not the third-party plugin (obs-mac-virtualcam by johnboiles) but an official one that was shipped with the previous version, and that 26.1.0 was able to launch without any problems.

asher-the-thrasher commented 3 years ago

no, this was caused by the plugin as seen by this section /Library/CoreMediaIO/Plug-Ins/DAL/obs-mac-virtualcam.plugin/Contents/MacOS/obs-mac-virtualcam

it is pointing to the plugin and not anything built in

wookayin commented 3 years ago

My apologizes --- the previous version I was referring to was 26.1.0, not 26.0.2. sorry for the confusion.

asher-the-thrasher commented 3 years ago

it happens if the plugin is started from what happened to me, everything was fine until I started the plugin by mistake, and then it crashed obs and I couldn't open it until uninstalling.

wookayin commented 3 years ago

With all due respect, I don't think this is correct. /Library/CoreMediaIO/Plug-Ins/DAL/obs-mac-virtualcam.plugin is the built-in DAL plugin that can be installed from OBS application itself, a built-in one (not a third-party). One can easily verify that by removing this directory and installing a new one from OBS, whose path is exactly the same.

It would be very strange if one needs to manually remove the official, built-in DAL plugin every time OBS gets upgraded.

WizardCM commented 3 years ago

@wookayin out of curiosity, had you at any point in the past either installed the third party virtual camera plugin, or used one of the OBS 26 release candidates?

wookayin commented 3 years ago

@WizardCM Yes I had both of them before. Before 26.1, I was using third-party virtual-cams. During the beta testing of OBS 26.1, I also used release candidates and my custom builds as well (I reported a few issues around virtualcams). But since the official release of 26.1, I have been using the official virtual cam plugin after the recommended uninstallation steps (i.e. rm -rf ...) which I was aware of.

i just downloaded obs on top of what I had and no new virtual camera got installed in that location so I still believe that this was caused by the plugin and not the built in one.

sorry if I'm getting in the way here, just trying to lend my eyes from another mac user and from seeing other people's reports with the same issue. please let me know if I'm just missing something here

wookayin commented 3 years ago

@asher-the-thrasher if that's the case, what do you have under /Library/CoreMediaIO/Plug-Ins/DAL/? What else than obs-mac-virtualcam.plugin? I'm pretty sure this is the official one that gets installed. Please make sure that you have clicked "Start Virtual Camera" at least once to have the plugin installed.

asher-the-thrasher commented 3 years ago

@wookayin all i have there is NDIVirtualCamera.plugin and plugins-info.txt which says Third party CoreMediaIO DAL Plug-Ins

wookayin commented 3 years ago

That is not an official one either. Did you click "start virtual camera" as I said? I doubt you did.

asher-the-thrasher commented 3 years ago

and to add on the installation of the virtual camera plugin is installed in that location and just caused a crash for me once i tried it to confirm that's where i installed it.

asher-the-thrasher commented 3 years ago

oops, it seems that you're correct, i didn't understand what you had meant by that, my bad, now the plug-in is listed in that location.

ramikalai commented 3 years ago

Any updates on this issue? Also, are people running this with a build that has ARC enabled or disabled?

crux commented 3 years ago

$ brew uninstall obs-virtualcam

did fix my crash after upgrading 26.1.2

Something which is also talked about here: https://github.com/johnboiles/obs-mac-virtualcam/releases

but teams is not longer showing the virtual cam source, but this could be totally unrealted. Checked in zoom and it works there.

@wookayin Please try system_profiler SPCameraDataType on the console:

Looks like this for me:
