Avplayer Stalling on Large Video Files Using Resource Loader Delegate

AVPlayer stalling on large video files using resource loader delegate

when the resource loader delegate fires up the NSURLConnection, the connection takes over saving the NSData to the pending requests and processing them. when the connection finished loading, the resource loader regains responsibility for handling the loading requests. the code was adding the loading request to the pending requests array but the issue was that they were not being processed. changed the method to the following and it works.

//AVAssetResourceLoader
- (BOOL)resourceLoader:(AVAssetResourceLoader *)resourceLoader shouldWaitForLoadingOfRequestedResource:(AVAssetResourceLoadingRequest *)loadingRequest
{
    if(isLoadingComplete == YES)
    {
        //NSLog(@"LOADING WAS COMPLETE");
        [self.pendingRequests addObject:loadingRequest];
        [self processPendingRequests];
        return YES;
    }

    if (self.connection == nil)
    {
        NSURL *interceptedURL = [loadingRequest.request URL];
        NSURLComponents *actualURLComponents = [[NSURLComponents alloc] initWithURL:interceptedURL resolvingAgainstBaseURL:NO];
        actualURLComponents.scheme = @"http";
        self.request = [NSURLRequest requestWithURL:[actualURLComponents URL]];
        self.connection = [[NSURLConnection alloc] initWithRequest:self.request delegate:self startImmediately:NO];
        [self.connection setDelegateQueue:[NSOperationQueue mainQueue]];

        isLoadingComplete = NO;
        [self.connection start];
    }

    [self.pendingRequests addObject:loadingRequest];
    return YES;
}

AVPlayer stops playing video after buffering

Since iOS 10.x, you can make some buffer settings, for example you can decide how many seconds you'll need to buffering your video:

    if #available(iOS 10.0, tvOS 10.0, OSX 10.12, *) {
        avPlayer?.automaticallyWaitsToMinimizeStalling = .playWhenBufferNotEmpty
        //preferredForwardBufferDuration -> default is 0, which means `AVPlayer` handle it independently, try more seconds like 5 or 10.
        playerItem.preferredForwardBufferDuration = TimeInterval(5) 
    }
