{
    NSURL *url = [NSURL fileURLWithPath:path];
    AVURLAsset *asset = [AVURLAsset URLAssetWithURL:url options:nil];
    NSArray *keys = [NSArray arrayWithObjects:@"commonMetadata", nil];
    [asset loadValuesAsynchronouslyForKeys:keys completionHandler:^{
         NSArray *artworks = [AVMetadataItem metadataItemsFromArray:asset.commonMetadata
                                                            withKey:AVMetadataCommonKeyArtwork
                                                           keySpace:AVMetadataKeySpaceCommon];

         NSMutableArray *artworkImages = [NSMutableArray array];
         for (AVMetadataItem *item in artworks) {
             NSString *keySpace = item.keySpace;
             if ([keySpace isEqualToString:AVMetadataKeySpaceID3]) {
                 NSDictionary *d = [item.value copyWithZone:nil];
                 [artworkImages addObject:[UIImage imageWithData:[d objectForKey:@"data"]]];
             } else if ([keySpace isEqualToString:AVMetadataKeySpaceiTunes]) {
                 [artworkImages addObject:[UIImage imageWithData:[item.value copyWithZone:nil]]];
             }
         }
         if(block) {
             block(artworkImages);
         }
     }];
