I attempt to export videos from Photo Library, but the export callback is never executed. I periodically check the progress of the export, and the progress is always zero.
AVAssetExportSession.Status always in waiting state
The code below works in 99.9% cases, but sometimes on some devices (absolutely randomly) it stops working, and only restart of the iPhone helps.
It is an example of the output URL: file:///var/mobile/Containers/Data/Application/B9EB607F-8F6F-4E3B-A6C3-88B580B8839F/Documents/last.mov
P.S. Some other video apps also freeze on video export (Videoleap, PicsArt) but some video apps (Filto, InShot) continue working
