Summary:
I see this problem for some video files in Camera Roll where they got via AirDrop or other sources, that is these videos aren't made by current iDevice's camera. It is reproducible for all devices that I tested with.

Steps to Reproduce:
For example, take a file .3gp format from Apple source https://support.apple.com/en-us/HT201549. After you downloaded it, you need to send it to device via AirDrop or email for example.
Then to export this file you can use
PHImageManager.default().requestExportSession(...)
or 
PHImageManager.default().requestAVAsset(...)
methods of PHImageManager shared instance.
Expected Results:
It should have exported it

Actual Results:
Error is received:
