Apple ReplayKit. Getting a contact FMOD support message.

FMOD Engine
1

Hello,

I’m using FMOD Studio Programmer’s API with iOS (tested version 1.06.07 and 1.06.10) and I get this error:
FMOD error! (28) An error occurred that wasn’t supposed to. Contact support.

This started happening when I tried implementing Apple’s ReplayKit. It happens right after calling RPScreenRecorder::startRecordingWithMicrophoneEnabled. Audio skips and then cuts out completely and doesn’t return until I restart the application. Apple’s RPScreenRecorder also fails and stops recording.

Any ideas?

Thank you,

Luigi

If you are using an API that requires microphone access you will need to ensure you are setting the appropriate AudioSession, in your case “PlayAndRecord”.

You can read more about the AudioSession API here. For best results, make sure you set these preferences before initializing FMOD.

EDIT:
Based on your log output it looks like the AudioQueue got killed. This seems like a bug in iOS, however one possible work around would be to suspend FMOD before you start recording, and resume FMOD once the recording begins. You can do this via System::mixerSuspend, System::mixerResume.

Sorry not sure what’s up with the formatting, it’s not respecting my line breaks.

Thanks for the quick reply Mathew.

Unfortunately this doesn’t seem to make a difference.

I get the same result regardless of which AVAudioSession category my app is set to. I’ve tried AVAudioSessionCategoryPlayAndRecord and a few others (previously my App was on AVAudioSessionCategoryAmbient). I confirmed that setCategory call is not returning an error and is returning success.

I’m going to attach the output log below from when my game invokes startRecordingWithMicrophoneEnabled. You can see that STARTED REPLAY KIT RECORDING happens and then my game switches from the menu music to the in game music (menu.m4a to Level_2_song.m4a). If I don’t try to record with ReplayKit, everything plays back fine.

(Log1 added to question)

I also confirmed that my AVAudioSession category gets set before FMOD gets initialized.

5

I’ve updated my answer with a potential work around.

This seems to help a little as apparently the replay actually starts recording and then fails shortly after.

I now get the following error from iOS: The operation couldn’t be completed. (com.apple.ReplayKit.RPRecordingErrorDomain error -5804.)

This just seems to indicate some generic recording error.

However, my audio still does not return after resuming and I still get the contact FMOD support error. I put the suspend/resume a little before/after the recording call as I suspect many of these calls are asynchronous.

Here’s a trimmed log, let me know if you’d like the full one (it’s quite long):
(Log2 added to question)

7

It looks like you have some FMOD calls after suspend but before resume, can you move those after the resume?

8

I’ll try. Are the suspend/resume calls synchronous?

9

Yes, they are synchronous.

10

Thanks for all the help Mathew.

Alright, so here are three different logs from three different runs. The first two are using the PlayAndRecord AudioSession and the final one is with Ambient (I tried this because PlayAndRecord greatly lowers the output volume, but I can tackle that separately). The first two are slightly different second one has this error: CodecAudioQueue::processAudioQueue : Cannot enqueue buffer for audio queue. (err: -66632)

(Logs 3, 4 and 5 added to question)

11

Sorry didn’t specify: result is the same, audio does not return and recording stops.

12

It looks like startRecordingWithMicrophoneEnabled has a handler block for when it completes. Can you try suspending FMOD before the call to startRecording, then call resume in the handler block? If that doesn’t work can you try resuming FMOD much later after starting the record? I suspect that ReplayKit is doing some internal reconfiguration of the audio stack so I want to make sure that is well and truly done before bringing FMOD back.

13

The STARTED RECORDING log entry is in fact from the handler when no error is passed in. I’ll add a 10 second delay and write back…

14

I added 10 second delays on top of every operation we introduced. It waits 10 seconds after calling suspend, 10 seconds after record, and 10 seconds after resume before it tries to do anything else.

It’s quite clear that as soon as FMOD resumes ReplayKit stops recording with that RPRecordingErrorDomain error -5804.

(Log 6 added to question)

15

Unfortunately this is looking like a bug with ReplayKit. My understanding is it should transparently record what’s happening in the game, but it seems there is some mutual exclusion going on.

16

Thanks Mathew, I started a thread on Apple’s ReplayKit forum too. Hopefully someone from Apple will chime in. Here’s the link, if you’d like to follow: https://forums.developer.apple.com/thread/20791

17

I haven’t been able to get anyone from Apple to look into it, I unfortunately don’t have any contact there. If you hear of an answer to this through another thread (or have a contact you could ask), could you please follow up here? Thanks again for all the help.

18

I have this -5804 error too with FMOD EX and ReplayKit. Since 7 months have been passed, I wonder if there is any progress on this problem? Does the mixerSuspend/mixerResume work around works?

19

Unfortunately there have been no developments on this to my knowledge. I’d recommend re-testing with the last Xcode / iOS SDK, if the bug still persists follow up with Apple.
