Known issues with beta 1:
  • Flatpak is currently being published to the wrong branch, will be fixed in next release
  • Crash when transitioning to a new scene using a transition override
  • Vertical audio meters are not properly grayed out



Getting this error when I run OBS 27.2, I've had the file for a while (OBS 25) now and my OBS installation is on a different drive, but after updating to the latest beta version, I get this popup dialog. Tried lots of things even creating a folder for it, still no solution.

Seems like that comes from a third party plugin, perhaps an ASIO plugin. I would contact the developer of that plugin for assistance.

Appears to use a bit less memory (~20MB in my setup). Not sure if it's the CEF improvements and/or QSV fixes. BlackMagic UltraStudio Mini Recorder still works. Lookin' good.

I tried using Beta2 on M1 iMac OS Monterey 12.1.
When I streamed it with niconico, the delivery stopped in a few minutes.

There was once a rumor that version 27.2 should get BETA support for the Apple silicon chips.
Unfortunately, in the release note of V 27.2 BETA 2, I don't find anything about M1 support.
Does the V 27.2 Apple Silicon get support without Rosetta?

I tried out the new Flatpak version and came across the following issue: After docking any browser window (I tried Twitch Chat and a custom Browser Dock) and then clicking on it, OBS and all other open windows basically froze. I was able to kill OBS from terminal though.

Apart from that the support of Blackmagic capture devices breaks using Flatpak. From what I read that issue probably has to be solved by their support though. I tried following these instructions (adapting the JSON to the latest drivers and the beta branch), wasn't successful though.

To bad that we need to log in to all accounts on every singel time we start the OBS studio beta.
It will be cool ot have remembered the logins and stays loged in on the streamings acouunts and all that, as the orginal obs studio does.

On every singel time I start the beta I need to log back in to everything lol. Isent it any way this can be remembered as the orginal version ?
