Setting up Player with AVPlayerItem.

[lurui1029]

Player stopped working when set up with an AVAsset downloaded from user's iCloud photo library using PHImageManager:

Error Domain=NSCocoaErrorDomain Code=257 UserInfo={NSURL=file:///var/mobile/Media/PhotoData/Metadata/DCIM/101APPLE/IMG_1858.small.MP4, NSUnderlyingError=0x2833487b0 {Error Domain=NSOSStatusErrorDomain Code=-12203 "(null)"}}

Request AVAsset using iCloud PHAsset returns an AVAsset with no VideoTracks

Solution

Set up Player with an AVPlayerItem.

PHImageManager provides either an AVAsset or an AVPlayItem for a video request from user's photo library. This issue does not occur when working with an AVPlayerItem.
