ReplayKitExample: Content Sizing Error (-5807)

[phukhanhlee]

When I "Start Conference" - (ReplayKitExample/ViewController/func startConference()) . It shows error "Error Domain=com.apple.ReplayKit.RPRecordingErrorDomain Code=-5807 "Recording interrupted by multitasking and content resizing" UserInfo={NSLocalizedDescription=Recording interrupted by multitasking and content resizing})" . I saw this bug in another demo projects about record screen with ReplayKit.

"Start Broadcast" is working well !

iOS 12.0.1 -> may be this is problem ? iPhone X -> may be this is problem ?

[solution] After I research -> here is the solution : just restart device and then it doesn't throw that error anymore. https://stackoverflow.com/questions/51440249/replaykit-startcapturewithhandler-not-sending-cmsamplebufferref-of-video-type/52307215#52307215

Hi @phukhanhlee,

We have seen similar failures which were solved by restarting the device (see known issues). I'm curious do you only encounter the error after debugging or on devices which are not used for development as well?

If there is a way to make our ReplayKit code more reliable I am all ears, but I didn't see anything actionable in the Stack Overflow question that you linked.

Hello Developers,

There have been several bug reports filed by Twilio, and by other parties against the iOS 12.x releases.

This Apple developer forum thread offers a probable explanation of the cause of the error. User Johnabre noticed:

After looking at system logs more, like others my theory is that permissions popup is interfering with ReplayKit ^^;

// ... logs

Here's logs for the identical logic when recording succeeds - permission alert activates, then permission alert deactivates, then ReplayKit starts:

A workaround may be possible, though ReplayKit doesn't seem to offer a standalone API to request screen capturing permissions. (You can ask for camera and microphone permissions in advance, if those are needed). We have cut ISDK-2539 to track this issue, and try workarounds.

Best, Chris

I have the same error... with your test app ReplayKitExample, Whats your solution ?

We think this is a bug in ReplayKit. We have reached out to apple and filed a radar for this.

Hi Developers,

This error should no longer occur on iOS 13 devices, and we have updated our known issues section with this information.

If you are still able to reproduce on an iOS 13.x device, please let us know.

Thanks, Chris
