Hi @abichal.jha,

Do you have some more information for us? Can you maybe provide which SDK version you are using?

In general, this stack trace does not include anything related to our BitmovinPlayer SDK, so with just the information we have right now, it’s super hard to determine where the crash is coming from.

Hi @davidsteinacher I’m using SDK 3.36.0.
No I don’t have more info this time.

Ok. Can you maybe provide information like:

  • do you maybe have the crash reason available as well?
  • which UI do you use?
  • do you have any event handler for onPlay, onPlaying, and onPaused and if so, do you call any Player API in those again?
  • does this happen only for a specific stream? E.g. only in live streams.

Crash reason is not available we only see sometime it crash on Destroy and some time play/pause.
Storyboard no SwiftUI is used.
We have event handler PlayerListener like onReady, onPlay, onPaused, onTimeChanged, onDurationChanged, onPlayerError, onStallStarted. We didn’t call any Player API but updating MPNowPlayingInfoCenter meta data.
This happen for both Live stream and VOD.

Hi David,

Any update on this issue? This issue has 215 crash events affecting 175 users in last 7 days which is a significant number. Thanks.

Sorry, I haven’t received any notifications on the replies.

However, without additional information, we cannot identify the proper crash reason. From the stack trace you provided, we can not see any reference to our BitmovinPlayer SDK so the crash could be unrelated to our Player.

Are there maybe additional threading information available or any possibility you could provide us clear reproduction steps?

but unable to replicate in debug mode.

Initially, you mentioned that you can not reproduce in debug mode. Does this mean you can reproduce it in a release build of your App?
