I'm using AVAssetExportSession to rexport a video edited by Adobe Premiere CC,
It's specific on iPhone XR/XS, I have exportSession.status failed with error :
Error Domain=AVFoundationErrorDomain Code=-11821 “Cannot Decode” UserInfo={NSLocalizedFailureReason=The media data could not be decoded. It may be damaged., NSLocalizedDescription=Cannot Decode, NSUnderlyingError=0x28338c4e0 {Error Domain=NSOSStatusErrorDomain Code=-16977 “(null)“}}
The video can be well played on native iPhone Player. On the others device (iPhone X, 6, 7, 8) no export error problem
