How to reproduce?

After upgrade to iOS 18, I want to Live Photo in video, seem not work anymore.

getMediaUrl => "file:///var/mobile/Media/DCIM/117APPLE/IMG_7666.MOV"
Exception when play this video: PlatformException(VideoError, Failed to load video: The file couldn’t be opened because you don’t have permission to view it., null, null)

I also tried fileWithSubtype
fileWithSubtype => file: File: '/private/var/mobile/Containers/Data/Application/973F8808-BD05-4354-9C1A-FA9CAC5A3AF9/tmp/.video/A10CB802-AB97-48D3-AF8C-9FB5D270BCBB_L0_001_1728264640.877920_o_IMG_7666.MOV'
Exception when play this video: PlatformException(VideoError, Failed to load video: Operation Stopped, null, null)

Is there any special porting need finish in iOS 18?
It play normal at iOS 17 (by getMediaUrl)

I think it should be different issue.
It still can reproduce after reboot.
This issue can reproduce more than one device. All devices are iOS 18.

[AlexV525]

We don't have iOS 18 devices around, unfortunately.

How about video assets? Do they played well on iOS 18?

Video Assets can play without issue.

The video url of live photo is got from the "privateFileURL".

(void)getMediaUrl:(NSString *)assetId
      resultHandler:(NSObject <PMResultHandler> *)handler
    progressHandler:(NSObject <PMProgressHandlerProtocol> *)progressHandler

if (@available(iOS 9.1, *)) {
        if ((asset.mediaSubtypes & PHAssetMediaSubtypePhotoLive) == PHAssetMediaSubtypePhotoLive) {
            PHAssetResource *resource = [asset getLivePhotosResource];
            NSURL *url = [resource valueForKey:@"privateFileURL"];
            if (url) {
                [handler reply:url.absoluteString];
                return;
            }
            [self fetchLivePhotosFile:asset handler:handler progressHandler:progressHandler withScheme:YES fileType:nil];
            return;
        }
    }
...

In iOS 18, if the "privateFileURL" is used to init the AVURLAsset and AVPlayerItem, the status of AVPlayerItem will be always AVPlayerItemStatusFailed and the video can not start to play.

In the other hand, the video url got from the following functions should work.

[self fetchLivePhotosFile:asset handler:handler progressHandler:progressHandler withScheme:YES fileType:nil];

@dodatw Could you help to confirm if the above comment works in your case?

[dodatw]

Hi Alex,

it is work if I call this function directlly

[self fetchLivePhotosFile:asset handler:handler progressHandler:progressHandler withScheme:YES fileType:nil];

Is it possiable fix in photo_manager ?
ex, check if iOS 18 don't call these function

            PHAssetResource *resource = [asset getLivePhotosResource];
            NSURL *url = [resource valueForKey:@"privateFileURL"];
            if (url) {
                [handler reply:url.absoluteString];
                return;
            }

[AlexV525]

Please apply the snippet until we fix this in the future release.

if (@available(iOS 18.0, *)) {
    [self fetchLivePhotosFile:asset handler:handler progressHandler:progressHandler withScheme:YES fileType:nil];
    return;
}
PHAssetResource *resource = [asset getLivePhotosResource];
NSURL *url = [resource valueForKey:@"privateFileURL"];
if (url) {
    [handler reply:url.absoluteString];
    return;
}
[self fetchLivePhotosFile:asset handler:handler progressHandler:progressHandler withScheme:YES fileType:nil];
return;
