SKVideoNode not displaying video

I am attempting to display a video using Sprite Kit and SKVideoNode on iOS 7.1. Apple's documentation makes this seem pretty straight forward. An example taken from the Sprite Kit Programming Guide:

SKVideoNode *sample = [SKVideoNode videoNodeWithVideoFileNamed:@"sample.m4v"];
sample.position = CGPointMake(CGRectGetMidX(self.frame),
[self addChild: sample];
[sample play];

I am trying the same code and seeing no video. The SKVideoNode is indeed in the node hierarchy. I've also tried multiple videos, all are H.264 AAC.

I found someone with a similar issue here. They seemed to solve it by instantiating an AVPlayer. That doesn't display video for me either. Ideas?

You should either add the video file to your bundle and load it through your bundle, or deactivate sandboxing.

I know the question is asked around 20 months ago, but never the less I thought I should share my learnings as well (it could be helpful to programmers who are working on SKVideoNode and facing the same issue, also there case is same as mine and mentioned below), related to SKVideoNode, video view display related issues.

I was recently exploring Sprite Kit where I found SKVideoNode to play video files on a SKScene. I created a GameScene inherited from SKScene and added an instance of UIImageView as backgroundImage on scenes skview ([self.scene.view addSubview:aView]) and next I created a SKVideNode's instance along with other UIKit subviews and SKNode childs added to the scene.view and scene respectively.

I configured the code for SKVideNode's as is mentioned in its documents of class refrence, I build and run the application to see video playing. But apart from video everything appeared on the screen, also when I increase the volume of the device, I was able to hear the sound(audio) of the video file.

Since I was able to hear audio so I thought I am missing some configuration or their is some issue due to which video view is not visible.

I tried some permutations and combination to use AVPlayer, different file formats but still the same behavior after this I started digging the views layering and z index concept to see if the video is not behind the background image or any other view, still same behavior.

Finally, what I did I removed every child and subviews (including background image) from the screen and tried to just play video, and this time the video view was visible on screen.

In short what I concluded with above behaviors is that, "if using Sprite Kit's SKVideoNode want to play videos than we should play them in SKScene instances, and not on above any UIKit views, as the instance of SKVideoNode is not visible if we are trying to add it at position where there is a UIKit view already present".

Well, as far as SpriteKit is concerned, it has SKView and SKScene inside a scene which allows a programmer to use both SpriteKit and UIKit elements in there games, but these types of issues could lead to a compromise in selecting the type of visual elements we want to use.

I had just solved it by converting the video file's format with Prism, MPEG4 video encoder. Hope it helps.

Couple of things first:

  1. You have to add the Foundation.framework to your project.
  2. Make sure you have added the video file to your project.
  3. Make sure your video file is one of these formats: .mov .mp4 .m4v .3gp .3gpp

Try out the sample code I have below:

#import "MyScene.h"
#import <AVFoundation/AVFoundation.h>

@implementation MyScene
{
     AVPlayer *_player;
     SKVideoNode *_videoNode;
}

-(id)initWithSize:(CGSize)size
{
    if (self = [super initWithSize:size])
    {
        [self setupMovie];
    }
    return self;
}

-(void)setupMovie
{
    NSURL *fileURL = [NSURL fileURLWithPath: [[NSBundle mainBundle] pathForResource:@"loop" ofType:@"mov"]];
    _player = [AVPlayer playerWithURL: fileURL];

    _videoNode = [[SKVideoNode alloc] initWithAVPlayer:_player];
    _videoNode.size = CGSizeMake(200, 100);
    _videoNode.position = CGPointMake(150, 150);

    [self addChild:_videoNode];

    _player.volume = 1.0;
    [_videoNode play];
}

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    //
}

-(void)update:(CFTimeInterval)currentTime
{
    //
}

@end
