Replay Kit in iOS 11

Unity Engine
,
1

Replaykit appears to fail on iOS 11. It requests permission to record, then nothing happens. Everything works fine in iOS 10. Any idea why this happens?

Replay Kit Permissions?

Hi Chris, we havenā€™t noticed anything unusual when testing ReplayKit on iOS 11. Could you report a bug with your project and exact steps describing what are you trying to do when it fails? Once you do that, please post the bug report number here. Thanks!

Have you tried with the last iOS 11 beta (15A5341f)??

4

So I tried running some tests with latest iOS 11 beta 5 and recording did fail a couple times. Then it ā€œmagicallyā€ started working. Not entirely sure what caused it to fail or start working again.
I passed it along to our developers, but it will be hard tracking down what causes the issue with such inconsistent results. Would be really useful if you guys could report bugs with your projects, this might help us to track down what exactly causes the problem and fix it.
Again, if you choose to do so, post the bug # here please.

Hey sorry for the late responseā€¦ I thought I had the forums set up to email me if there were responses. The same thing happened with me with inconsistency and now it appears to be working consistently. Iā€™m not really sure what happened, sorry I canā€™t give more details!

I have the same issue; tried two 3rd party assets as well, dialog asks to use the cam and mic, then nothing. It worked half way with a previous beta of ios11 (beta5), now on beta v8 not.

Have tried both Unity 2017.1 and 2017.2, no difference.

From all I can read, a lot of reports on this.

Anyone have updated info on this issue?

7

Can you try the GM seed of both Xcode and iOS 11. I was told this was fixed on appleā€™s side

8

Ah; I missed those releases; I will try it, hopefully it solves the issueā€¦TBA

9

Solved - the iOS11 GM seed solved it.
Thanks for the tip!

10

Still not working for me. iOS 11 Release version. Error message says recording is interrupted by another application.

11

I have the same problem. Its been working half of the time when i had iOS11beta 6 and xcode9 beta.
I am having issues with Unity Patch 5.6.3p4, iOS11 and Xcode9.

Does it work for you every time JoMaHo? What is your secret???

12

No, Iā€™m sorry to say it is very inconsistent; I do not have time to persue the issue now, just looking into this forum to see how it goes. Something is seriously wrong. 3rd party assets with Replaykit are also mailfunctioningā€¦

13

Thank you for the reply JoMaHo!

Did anyone try prime31 replay kit? or EveryPlay?

Release note
Prime 31
Version 2.10

  • iOS 11 compatibility update

Hi Everyone,
I spent the last 24 hours debugging this issue. Below is the relevant error. Iā€™ve tested this with 5.6.3f1 and 5.6.3f4 and originally got it on 5.6.2f1. Even when you look at UnityReplayKit file in Xcode it tells you that you should be calling the function from main thread as a warning. It happens with iOS 11 GM and Xcode 9 GM. Unfortunately this error only happens about %20 so you have to try a few times.

Hey behradMan

Just wondering, are you trying to record with front camera on and mic?

I cant even get basic functionality of capturing a video w/ game audio workingā€¦

16

Nope. Iā€™m just recording the screen with mic(which the user can deny). I can start recording but sometimes the stop recording handler is not called with the error I pasted above. Iā€™m also using the built-in replay kit api unity provides and not a plugin.

If anyone from Unity can take a look at the error, Iā€™m pretty sure it should be a quick fix especially since Xcode highlights it as a warning in UnityReplayKit.mm file. Here is even the same error for another case:

17

hey guys, i just purchased prime31 replayKit and it worked.
we will hammer it tomorrow on a bunch of devices and will post the results

best I

18

I tried with Prime31 too and get the same error message.

19

Any update on this? I bought Prime31 and it had the same problemā€¦

20

nope,
using Prime31 replayKit I get this error:
