Play video from camera roll in SpriteKit SKVideoNode - sprite-kit

Question

I've got most of this working but I'm stuck with something that might be simple. Im trying to play a video from the camera roll in SpriteKit. A video will play from the main bundle, and the video picker also works until I choose the video. I think I'm locking the main thread because when choosing the video the picker freezes. You're help is extremely appreciated.
.h
#import <SpriteKit/SpriteKit.h>
#import "GameViewController.h"
#import <MobileCoreServices/UTCoreTypes.h>
#interface GameScene : SKScene<UINavigationControllerDelegate,UIImagePickerControllerDelegate>
#end
.m
#import "GameScene.h"
#import <AVFoundation/AVFoundation.h>
#implementation GameScene {
AVPlayer *player;
SKVideoNode *videoNode1;
NSURL *fileURL;
NSString *moviePath;
UIViewController *viewController;
}
-(void)didMoveToView:(SKView *)view {
player = [AVPlayer playerWithURL: fileURL];
videoNode1 = [[SKVideoNode alloc] initWithAVPlayer:player];
videoNode1.size = CGSizeMake(self.frame.size.width,self.frame.size.height);
videoNode1.position = CGPointMake(self.frame.size.width/2.0f,self.frame.size.height/2.0f);
videoNode1.zPosition = 100.0f;
[self addChild:videoNode1];
player.volume = 1.0f;
[videoNode1 play];
}
- (void)getVideo {
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];
viewController = self.view.window.rootViewController;
[viewController presentViewController: imagePicker animated: YES completion:nil];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];
if (CFStringCompare ((__bridge CFStringRef) mediaType, kUTTypeMovie, 0) == kCFCompareEqualTo) {
fileURL = (NSURL*)[info objectForKey:UIImagePickerControllerMediaURL];
moviePath = [fileURL path];
if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum (moviePath)) {
UISaveVideoAtPathToSavedPhotosAlbum (moviePath, nil, nil, nil);
}
player = [AVPlayer playerWithURL: fileURL];
}
viewController = self.view.window.rootViewController;
[viewController dismissViewControllerAnimated:YES completion:nil];
NSLog(#"place video");
}

Answering my own question for others who want this feature. You must set up your node and player in the imagePicker method.
- (void)getVideo {
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];
viewController = self.view.window.rootViewController;
[viewController presentViewController: imagePicker animated: YES completion:nil];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
fileURL = [info objectForKey:UIImagePickerControllerMediaURL];
[picker dismissViewControllerAnimated:YES completion:NULL];
player = [AVPlayer playerWithURL: fileURL];
videoNode1 = [[SKVideoNode alloc] initWithAVPlayer:player];
videoNode1.size = CGSizeMake(self.frame.size.width, self.frame.size.height);
videoNode1.position = CGPointMake(self.frame.size.width/2.0f, self.frame.size.height/2);
videoNode1.zPosition = 100.0f;
[self addChild:videoNode1];
player.volume = 1.0f;
[videoNode1 play];
}
