How to play movie with a URL using a custom NSURLProtocol?

Question

As you know,play a movie with MPMoviePlayerController object using

[[MPMoviePlayerController alloc] initWithContentURL: aURL];

now ,i want

Answer 1

@property AVPlayerViewController *avPlayerVC;
@property NSData *yourDataSource

// initialise avPlayerVC
    NSURL *dummyURL     = [NSURL URLWithString:@"foobar://dummy.mov"];// a non-reachable URL will force the use of the resourceLoader
    AVURLAsset *asset   = [AVURLAsset assetWithURL:dummyURL];
    [asset.resourceLoader setDelegate:self queue:dispatch_get_global_queue(QOS_CLASS_USER_INTERACTIVE, 0)];

    AVPlayerItem *item = [AVPlayerItem playerItemWithAsset:asset];

    self.avPlayerVC.player = [AVPlayer playerWithPlayerItem:item];
    self.avPlayerVC.player.actionAtItemEnd  = AVPlayerActionAtItemEndNone;



// implement AVAssetResourceLoaderDelegate

- (BOOL)resourceLoader:(AVAssetResourceLoader *)resourceLoader shouldWaitForLoadingOfRequestedResource:(AVAssetResourceLoadingRequest *)loadingRequest {

    loadingRequest.contentInformationRequest.contentType    = (__bridge NSString *)kUTTypeQuickTimeMovie;
    loadingRequest.contentInformationRequest.contentLength  = self.yourDataSource.length;
    loadingRequest.contentInformationRequest.byteRangeAccessSupported   = YES;

    NSRange range = NSMakeRange((NSUInteger)loadingRequest.dataRequest.requestedOffset, loadingRequest.dataRequest.requestedLength);
    [loadingRequest.dataRequest respondWithData:[self.yourDataSource subdataWithRange:range]];

    [loadingRequest finishLoading];
    return YES;
}

Notice the use of a dummy URL to force AVPlayer to use the AVAssetResourceLoaderDelegate methods instead of accessing the URL directly.
