Expected Behavior

Recording full screen "Display Capture" should not freeze after a few seconds.

Current Behavior

When using "macOS Screen Capture" Source recording works as expected until you go full screen. After this the video recording runs for a few seconds then freezes, audio recording continues as expected. This occurs in testing with Chrome + Youtube and Plex (not full screen works correctly but then freezes when going full screen).

What's really interesting is that if you use a "Window Capture" for the Chrome tab and go full screen the recording is black when the window is not "in focus" but when you watch the full screen video it records as expected (doesn't freeze).

The legacy "Display Capture" does freeze and works as expected.

Steps to Reproduce

1. Add macOS "Display Capture" source
2. Start recording screen
3. Open youtube video in chrome
4. Make video full screen
5. Stop recording
   ...

Anything else we should know?

Could you please run log stream --system | grep "replayd" in a Terminal while reproducing the issue and upload the output as a txt file on a comment?

If this is the same issue I came across and mentioned in discord recently, @gxalpha confirmed it and I think figured out the source of the issue. it was specifically an issue with macOS Screen Capture Display capture on 12.x with any application or window in fullscreen. Window captures weren't affected in my tests, and I don't think application captures were. Behavior changes in 13.

@PatTheMav Please find requested output attached

[PatTheMav]

OK, an important detail seems to be that replayd reports no issues (frames are supposedly captured just fine) but there are no frame updates arriving in OBS.

I've also replicated a behaviour I found debugging another issue: The recording is updated if the cursor is moved, but only if the cursor is hidden. If the cursor is set to be displayed, no movement will update frames.

[michaelgambold]

After the release of MacOS 13 I tried out the "macOS Screen Capture" source again it does not freeze whilst recording full screen (with a 5 minute test). I'll try a longer test and report back.

[Knownerd]

For me, it freezes in longer periods, let's say 30 min. The legacy capture doesn't freeze, but it is depreciated and has a delay of nearly 1s.

[PatTheMav]

We are aware of such issues that are due to a bug in macOS 13.0 - fixes are supposed to come with macOS 13.1, so we have to wait for that update to be released.

I have livestreams freeze after about 20 minutes using macOS Window Capture. Is this issue with all macOS Screen Capture types? Is this issue (Display Capture) fixed with the macOS 13.1 update or is there an OBS update that must be applied as well?

[gxalpha]

Is this issue with all macOS Screen Capture types?

I believe the issues where the "macOS Screen Capture" source would randomly freeze apply to all capture types.

Is this issue (Display Capture) fixed with the macOS 13.1 update or is there an OBS update that must be applied as well?

The random-freezing issues currently known with the source are resolved by updating to macOS 13.1, no OBS update is required. If you run into the problem on macOS 13.1, please let us know.

[cboxgo69]

Okay, that's good to know. I'll try Ventura 13.1 today and see how it goes. As for random, it's not random at all. It's predictable at about 20-30 minutes even if you just walk away and leave the game running and come back. I should be able to see if it happens without streaming more than that. Thanks

[gxalpha]

As for what this issue was originally about, this looks like it was because of our Display Capture workaround on macOS 12.
Because of all the problems, we have removed the "Display Capture" option from the "macOS Screen Capture" source on macOS 12, and recommend either using the old "Display Capture" or updating to macOS 13.

As such, I'm going to close this issue.

If anyone comes across any other problems (freezing, etc) with the macOS Screen Capture source:

• Update macOS to 13.1
• If it still occurs, please open a new bug report (preferably having gone through our support channels first)

Hi, i've the same problem with OSX 13.4 . Using the Mac OSX Screen Capture result in a screenshoot of the desktop background recorded , audio work as exepcted. The video freeze immediatly, like we try to record an image instead the screen. I'm only able to get a video ouptu using the screen capture from the obsolete menù.

[gavink97]

I'm experiencing the same issue (Where the video freezes) on Apple Silicon OSX 13.6 using MacOS Screen Capture to capture my display.

Deleting the MacOS Screen Capture Source & creating a new one seemed to solve the issue.

To reproduce the source freezing on the corrupted MacOS Screen Capture simply restart OBS and the source will be frozen.

tested with OBS 30 beta3 still freezing

I've seen some evidence of this issue occurring in 13.6.0 on a separate app I'm working on using SCK. Is it possible that this 13.0 bug has returned?

I haven't seen any evidence of the original issue from this thread reappearing.

That said, if you are working on an app using SCK, I'd suggest verifying that the behavior occurs when run outside the Xcode debugger; I myself have an SCK application that fails to record some fullscreen applications if it is currently being run in the debugger.

[jnpdx]

Thanks -- it's definitely occurring outside of the Xcode debugger, but it's good to know that it may be more susceptible.

In the event that this issue happens, I assume that frames stop getting delivered to func stream(_: SCStream, didOutputSampleBuffer sampleBuffer: CMSampleBuffer, of outputType: SCStreamOutputType) completely, right? It's not just that it erroneously reports frames with idle as the status?

[Merdin]

Just wanted to let you know that my macOS Screen Capture source is also freezing after x minutes of recording.

x = random number.

OBS Studio 29.1.3 (64 bit)
MacBook Pro - M2 Pro (16GB)
macOS Sonoma 14.0

[PatTheMav]

Please refrain from "I have this issue too" comments on GitHub, especially without any logs or helpful information - they do not contribute to resolving the issue, they will not help maintainers to find the root cause of the issue quicker, they will not change the priority of the issue.

What we need instead are clear steps to consistently (that is: the problem occurs at every attempt) reproduce the issue, because without those the issue cannot be investigated or its root causes either fixed or reported to Apple.

[quantuminformation]

Im on mac 14, so I shouldn't expect mac screen to capture atm?

I dont see the old display capture
