Replay Kit in iOS 11

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?

 

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

 

Hey sorry for the late response... 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. I'm not really sure what happened, sorry I can'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?

 

Ah; I missed those releases; I will try it, hopefully it solves the issue....TBA

 

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

 

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

 

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????

 

No, I’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 mailfunctioning...

 

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. I'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 working....

 

Nope. I'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. I'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, I'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:

https://stackoverflow.com/questions...accessing-cachedsystemanimationfence-requires

 

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

 

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

 

Any update on this? I bought Prime31 and it had the same problem...

 

nope,
using Prime31 replayKit I get this error:
2017-10-02 22:52:37.526478-0700 XXXX[395:54101] screenRecorderDidChangeAvailability. is available: YES

http://support.prime31.com/28859/replaykit-inconsistent-on-ios11?show=28914#c28914

 

I have the same problem:
ReplayKit.APIAvailable returns "true", and ReplayKit.StartRecording(); does show the permissions popup, but then nothing happens and ReplayKit.isRecording returns "false".
It did work once, strangely enough.

Could it be that the old recording should be deleted ( ReplayKit.Discard ()) before starting a new one?

 

Bump any news on this?

Thanks!!

 

ReplayKit is not working correctly on iOS11! After I call StopRecording, sometimes the recording is never available.

 

Yes, Replay is NOT working. If someone at Unity could come up with a fix it would be much appreciated. I am using 2017.1.2p2.
It seems to start recording....but nothing works after that...

i am getting the following message:
Exception: accessing _cachedSystemAnimationFence requires the main thread

 

This definitely worked perfectly before 11. Is the new OS screen recorder function overriding this somehow? I'm not using prime31 but UItimate Mobile on Unity 5.6.3. The problem for me is pressing my in-game 'record' button but never getting the edit/share popup after stopping and calling it.

 

Bump - any news on this issue?

 

I just tried recording a video with ReplayKit and got

[general] Exception caught during decoding of received reply to message 'startRecordingWindowLayerContextIDs:windowSize:microphoneEnabled:cameraEnabled:broadcast:systemRecording:captureEnabled:listenerEndpoint:withHandler:', dropping incoming message and calling failure block.

So what is the status of this? Is there a way to solve this or do we have to wait for a new version of IOS/Unity?

 

The solution is to use a native replaykit bridge and not the Unity API.

https://github.com/miyabi/unity-replay-kit-bridge

 

Hi so I tried implementing this solution but with no luck. I tested the example that came with the bridge and the example works. As a result, I believe that this problem everyone is having is related to using ARKit + Replay Kit = BAD.

I have not found a solution yet.

 

ARKit + ReplayKit works. Whatever you are trying to achieve may take some more iOS knowledge on your behalf.

 

did you get front facing ARKit + ReplayKit to work?

or just old world facing

 

So is there no way to fix this bug yet?

 

I gave up on replay kit.

Natcorder has been way more reliable!
https://assetstore.unity.com/packages/tools/integration/natcorder-video-recording-api-102645

 

Unity should probably just buy out Nat*

 

Bump - any news on this issue?

 

I bought this for $50 and was disappointed with the documentation and I'm not using it. I just needed to record video on iOS and replay kit is free and worked fine for me.

 

Has anyone noticed that the Unity replay kit video component in Xcode was deprecated with iOS 9? They are using this old component and it has problems.

It does work, but the buttons are basically untappable on the iPhoneX ( see attachment ) All of the buttons are too close to the edges or in the notched area :/ -- not something you could ship to customers.

Any ideas for workarounds?

 

@michaelcolin, sorry to hear of your troubles. I can't speak for your particular problems, but natcorder has been fantastic for my purposes. Along with amazing support from the developer.

 

I would not jump on Netcorder too quickly if you building for IOS. On iPhone X I have to go to a very low resolution to get it to work and even then it sometimes just does not work. It appears to be the better solution right now but its not ready for consumer facing products on the latest devices.

 

Hi, just running into this issue. Is there no path to getting ReplayKit to work on 5.6.6?

 

Hi forum people, I'm getting this problem for a week and could not found any solution. The problem is still there?

 

use ReplayKit for live stream to Youtube still not working

Unity version 2019.2.17f1 . ---> on mac os xcode version -> Version 11.0 (11A420a) .
after saving video unity crash and video launched .
the main issue is above log when create a build on xcode (archive). build working fine when i directly run on device via xcode but cant create build . whyy ?

 

Hi,
Incase if any one is interested, we have Cross Platform Replay Kit on asset store where we have our own custom implementation. This avoids microphone issues and many other issues you see in native replay kit framework for iOS.

Along with it, plugin offers screen recording on Android platform too with same unified api!

Cheers,
