@JJSarrasin

Note, it would be helpful if you could provide a full bugreport but I assume that all you have from the crashlytics reports are these stack traces?

From the stack trace it appears to be some issue within the framework in processing display info and it might be that the Vantiva TV Box has some issues in its android implementation around this.

I would suggest filing a bug with Vantiva. In addition, you could try and have some custom logic to disable video tracks via TrackSelectionParameters if playing on that model of device and there are not any displays attached. Then if a display is attached, you can enable video tracks. It may add some latency but may prevent those errors.

@microkatz You assumed right, we only have a few Crashlytics reports (about 0.1% of users over the last 30 days).

We’ve just opened a ticket with Vantiva and will keep you updated.

Vantiva couldn't investigate it without further logs.. We'll close the issue until we could reproduce it on one of our device and take the full logs. I will reopen if needed. Thanks
