AVPlayer instances failing and cutting to black screen

Hi,

I have an app attempting to do some video playback and editing, but I'm having an issue where with some videos, some operations like AVQueuePlayer/AVPlayerItem.seek will cause all players to move to .failed and just show black.

The only indication the OS gives the app that this has happened is some logs relating to the haptic engine:

[hcln]     AVHapticClient.mm:1309 -[AVHapticClient handleServerConnectionInterruption]: [xpc] Entered (due to connection interruption) for client ID 0x100031e

[hapi]     CHHapticEngine.mm:614  -[CHHapticEngine finishInit:]_block_invoke: ERROR: Server connection broke with error 'The operation couldn’t be completed. (com.apple.CoreHaptics error -4811.)

In the device console, the most likely culprit seems to be this (reported by kernal):

EXC_RESOURCE -> mediaserverd[768] exceeded mem limit: ActiveSoft 2500 MB (non-fatal)

If my assumption is correct, is it possible to mitigate this issue before mediaserverd and all the associated players get killed?

My understanding of this is that AV memory is separate to the app memory so responding to the usual didReceiveMemoryWarningNotification isn't applicable in this case, and that notification doesn't seem to be being send before these failures.

Thanks

It does sound like media services are being reset. Please file a report and include a sysdiagnose plus the approximate time the issue occurs.

Thanks, I've raised FB9750875

Is there anything I can do to react to this kind of media service reset? I can observe AVAudioSession.mediaServicesWereResetNotification but this doesn't seem to be posted when this issue occurs
